Harris v. Astrue

MEMORANDUM OPINION AND ORDER SUSAN E. COX, United States Magistrate Judge. Plaintiff Theresa Harris seeks judicial review of a final decision made by the Commissioner of the Social Security Administration (“SSA”) denying her application for Disability Insurance Benefits (“DIB”) and Supplementary Security Income (“SSI”) under Title II and Title XVI of the Social Security Act. Pursuant to the Commissioner filing a motion for Summary Judgment, this Court must decide whether to affirm, reverse, or remand that decision. *983 This Court grants the plaintiffs motion to remand [dkt. 25] and denies the Commissioner’s motion to affirm [dkt. 31]. PROCEDURAL HISTORY December 31, 2003 was the last date on which plaintiff was eligible for DIB and SSI. 1 On May 4, 2004, plaintiff protectively filed for DIB and SSI claiming disability since December 13, 2001. 2 Plaintiff later amended this disability date to December 30, 2003. 3 She alleged in her DIB and SSI application that she suffered from lumbar stenosis, which prevented her from being able to walk without a walker or a cane. 4 Plaintiffs application stated that her illness began on December 22, 1994, and became so severe by December 13, 2001 that she could no longer work. 5 On November 18, 2004, the SSA denied her application. 6 On January 13, 2005, plaintiff filed a timely request for reconsideration, noting in her disability report that her medical condition had not changed. 7 On March 10, 2005, the SSA denied plaintiffs request for reconsideration, so on April 29, 2005, plaintiff filed a request for a hearing by an administrative law judge (“ALJ”). 8 On August 16, 2006, ALJ Joseph Donovan presided over a hearing finding plaintiff not disabled and denying her application for DIB and SSI. 9 On June 11, 2007, plaintiff filed a request for review of the ALJ’s decision. 10 STATEMENT OF FACTS Born on September 6, 1953, plaintiff was fifty-two years old when she appeared before the ALJ. 11 She had completed high school and graduated from a four year institution with a liberal arts degree. 12 After graduating from college, plaintiff worked as a data-entry operator in a post office and as a mail room supervisor in an electronic supervising company. 13 In 1994, plaintiff was involved in a head-on automobile collision and soon after began experiencing back pain and muscle spasms. 14 Even as she complained to her doctors of severe back pain that prevented her from walking properly, she worked full-time as: a group home assistant responsible for monitoring mentally handicapped patients; an in-school detention, suspension, and study-hall supervisor; and finally; a substitute teacher. 15 On December 13, 2001, plaintiff terminated her employment as a suspension supervisor and has not attempted to work again. 16 On September 23, 2004, plaintiff filed a disability report as part of her application for disability insurance benefits under Title II of the Social Security Act, alleging that her infliction with lumbar stenosis, which was first noticed in a magnetic resonance imaging (“MRI”) scan taken on March 24, 2004, has existed since December 13, 2001, the last date she was insured (“DLI”). 17 *984 I. Plaintiffs Medical History Before The Date of Last Insured After her December 1994 automobile accident, plaintiff began experiencing back pain and muscle spasms. 18 In 1995/1996 plaintiff sought treatment at the Mayo Clinic for back spasms and lower back pain. 19 At that time, plaintiff was found to have some crushed thoracic vertebrae in her upper back. 20 The 2004 documentation referencing this time period reports that after 1995/1996 the plaintiff subsequently experienced “some intermittent discomfort, but was okay for a couple of years.” 21 In fact, in 1996, plaintiff told her doctor that she had no complaints and wanted to discontinue her pain medication. 22 In March of 1998 plaintiff began to see her primary care physician, Charlotte H. Mitchell, M.D., of St. James Hospital, for help with lower back pain. 23 In April 1998, medical records indicate that plaintiff had “no complaints.” 24 Nonetheless, soon after she began seeing Dr. Mitchell, plaintiff had an MRI taken of her spine. 25 Medical records dated April 14, 1998, from the Department of Radiology at St. James Hospital, indicated that “there is no inter-vertebral disk space narrowing or degenerative changes. There is a slight lumbar scoliosis demonstrative of a lumbar curvature with convexity towards the left. No bony destructive lesions are noted.” 26 On April 27, 1998, the radiologist, Walter S. Tan, M.D., read the results of the same MRI and reported to Dr. Mitchell that plaintiff had a “normal MRI of the thoracic spine,” because the saggital scans of her spine “show normal alignment of the thoracic vertebral bodies ... no fracture or destructive lesion in the bones ... no abnormal focus of increased or decreased signal in the bones ... [and] no spinal canal stenosis or herniated disc.” 27 Plaintiff had another MRI taken of her spine on July 13, 1998, which indicated that she had a T12, LI disk herniation. 28 Dr. Mitchell prescribed physical therapy to help mitigate plaintiffs lower back pain but, according to plaintiff, the pain never subsided. In 2000, Dr. Mitchell began treating plaintiff for a balance problem that was making it difficult for plaintiff to walk without using something to stabilize herself. 29 Plaintiff testified that her balance problems worsened in 2001 because she was walking with a cane. 30 In 2002, Dr. Mitchell reexamined plaintiffs back and found signs of attaxic gait secondary to plaintiffs back. 31 Between July 13, 1998 and December 31, 2003, the last date on which plaintiff was eligible for DIB and SSI, she had no more MRIs taken of her spine. The SSA tried to obtain sufficient medical records for the period between July 1998 and the end of 2003 documenting the condition of plaintiffs spine during this five year span, to no avail. 32 In this regard, there is only *985 sparse documentation available from plaintiffs physician at the time, Dr. Mitchell. The documentation available indicates that in May of 1999, plaintiff complained of stiffness in her back, but that her back pain was improving by June 1999. 33 A record from June 2001 indicates that plaintiff had a back “flare up” for one month prior to her doctor’s visit, where she was prescribed physical therapy. 34 Records from April 2002 indicate that plaintiff had some lower back discomfort and that she “wants [another] order for [physical therapy] because she didn’t go before.” 35 In May of 2002 plaintiff reported that the physical therapy was helpful, but that she had back stiffness, so it was recommended that she continue physical therapy. 36 The documentation available from this five year time period contains only three references to plaintiffs balance problems, twice in 1999 and once in 2002. 37 II. Plaintiffs Medical History After The Date of Last Insured Plaintiff switched doctors and received medical treatment from Kathryn Burke, D.O., from February 4, 2004 to July 26, 2004. 38 Dr. Burke initially noted that plaintiff had an extremely tense lumbar musculature and decreased range in motion in flexion and extension, so she scheduled an MRI for March 24, 2004. 39 The MRI revealed that “disc desiccation is evident at L3-4, L4-5 and L5-S1, manifest by a loss of normal disc height and T2 signal intensity.” 40 However, the lumbar vertebral bodies remained preserved in height and alignment with no signs of fracture or subluxation. 41 The MRI also demonstrated “normal signal and morphology” of the conus medullaris, the terminal end of the spinal cord, 42 and the cauda equine, the bundle of spinal nerve roots for all the spinal nerves below the first lumbar. 43 At L3-L4 and L4-L5, the MRI showed narrowing of the thecal sac to less than one centimeter in diameter, “secondary to diffuse bulging disc, bilateral facet arthropathy, and hypertrophy of the ligament flavum.” 44 On April 12, 2004, plaintiff received an exam and referral from Richard Freeman, M.D., at the Midwest Minimally Invasive Spine Specialists for her back pain. 45 Between April and August of 2004, plaintiff saw Ramesh P. Kanuru, M.D., of DBA Pain Management Consultants for epidural injections to moderate her back pain, and she visited Midwest Physicians Group, Ltd. for physical therapy. 46 She also took Betra, a muscle relaxer that Dr. Kanuru prescribed to treat her back pain. 47 In July and August of 2004, Aida Spahic-Mihajkovic, M.D., treated plaintiff for her back pain and inability to walk. 48 Dr. Mi *986 hajkovic prescribed plaintiff Xanax for her anxiety and Paxil for her fear of falling. 49 On October 12, 2004, Dr. Burke submitted a report to the Bureau of Disability Determination Services (“BDDS”) documenting the condition of plaintiffs spine. 50 In the report, Dr. Burke posited that plaintiffs back problems began sometime “prior to 3/1/04 (approximately) 1995/1996.” 51 Dr. Burke noted that the plaintiff complained of pain and noted physical findings concerning plaintiffs need for help walking and standing and her need for constant back support. 52 The report went on to note the presence of lumbar stenosis, and to diagnose the plaintiff with spinal stenosis as well as psychosomatic problems. 53 On October 12, 2004, Dr. Burke also prepared a Chronic Pain Residual Functional Capacity (“RFC”) Questionnaire. 54 Dr. Burke’s overall prognosis of plaintiffs condition was poor. 55 The report named an inability to walk without assistance, muscle spasms, and abnormal gait as positive signs of plaintiffs spinal ailment. 56 Dr. Burke further opined that plaintiff was severely limited in dealing with work stress and often experienced severe symptoms that interfered with her ability to concentrate. 57 Dr. Burke surmised that plaintiff would likely be absent from work twice a month as a result of her impairments or treatment for her impairments. 58 On June 13, 2005, Dr. Spahic-Mihajkovic evaluated plaintiffs health in a Mental Impairment Questionnaire. 59 Dr. Spahic-Mihajkovic gave her a Global Assessment of Function (“GAF”) score of 60-70 out of 90 total points, but noted that plaintiff would likely suffer from chronic panic disorder and a fear of falling for at least twelve months. 60 Mental health professionals use the GAF to convey an individual’s psychological, social, and occupational functioning on a spectrum in which scores between 41-50 indicate serious, 51-60 indicate moderate, and 61-70 indicate mild symptoms. 61 Dr. Spahic-Mihajkovic credited mood disturbance, emotional liability, recurrent panic attacks, decreased energy, persistent irrational fears, generalized persistent anxiety, somatization unexplained by organic disturbance, and pathological dependence or passivity as the symptoms on which she based her diagnosis. 62 Dr. Spahic-Mihajkovic’s clinical findings were that plaintiff relied on others to physically support herself while walking due to a fear of falling. 63 In her estimation, plaintiff would have moderate restrictions on her activities of daily living as a result of mental impairments, but would seldom experience deficiencies in concentration, persistence, or pace resulting in a failure to complete tasks in a timely manner. 64 *987 In the same questionnaire, Dr. Spahic-Mihajkovic also assessed plaintiffs mental abilities and aptitudes in relation to the performance of unskilled labor. 65 The questionnaire asked Dr. Spahic-Mihajkovic to rank plaintiff with respect to the abilities listed in terms of “poor,” “fair,” “good,” or “very good.” 66 While plaintiff was not “poor” in any category, Dr. Spahic-Mihajkovic noted that plaintiff had only a “fair” ability to remember work-like procedures, maintain regular attendance, be punctual, perform at a consistent pace, and deal with normal work-stress, including the stress of semiskilled and skilled work. 67 She noted that plaintiff would be “good” at completing a normal workday or work week without interruptions from psychologically based symptoms, being cognizant of normal hazards and taking appropriate precautions, understanding, remembering, and executing detailed instructions, setting realistic goals, and making plans independently of others. 68 The report also stated that plaintiff had a “very good” ability to understand, remember, and implement very short and simple instructions, maintain attention for two hour segments, sustain an ordinary route without special supervision, work in coordination with or proximity to others without being unduly distracted, make simple work-related decisions, ask simple questions or request assistance, accept instructions and negative feedback, get along with others without unduly distracting them or exhibiting behavioral extremes, and respond appropriately to changes in a routine work setting. 69 III. August 16, 2006 Hearing Before the ALJ On August 16, 2006, the plaintiff appeared before the ALJ along with two expert witnesses, Daniel V. Girzadas, M.D., an orthopedic surgeon, and Pamela Tucker, a vocational therapist, to comment on plaintiffs medical condition and her ability to hold a job in spite of her impairments. 70 The ALJ first questioned plaintiff about physical limitations that she had experienced stemming from her back pain and balance difficulties. 71 Depending on the degree of back pain she was experiencing at the time, plaintiff attested that she could consecutively sit for one to two hours and could stand for two to three hours. 72 Plaintiff did testify that she could sit for longer periods of time, provided that she took short breaks to stand up, stretch, and move around. 73 She also testified that with the assistance of a cane or a walker, prescribed by Dr. Burke, she could walk for as long as she wanted. 74 Plaintiff could raise her arms, reach up and touch to the side with both arms, put her arms straight out, move about on her hands and knees, crouch, and even bend at her hips without any assistance, but she required help standing up when she was low to the ground. 75 Plaintiff had no problems with her hands or feet, and she initially testified *988 that she could lift more than five pounds even from a seated position but, upon further questioning, she clarified that she could lift only about five pounds due to arthritis in her shoulder blade. 76 Plaintiff could, however, push and pull a five pound cart with her left arm, and could pull such a cart with her right arm. 77 The ALJ next questioned orthopedic surgeon Dr. Girzadas about plaintiffs medical conditions within the contexts of the standards governing disability insurance. 78 According to Dr. Girzadas, the medical reports from February 4, 2004 indicated that plaintiff was suffering from mid back pain for 10 years, pain which had been the same since plaintiffs 1994 motor vehicle accident. 79 Dr. Girzadas confirmed Dr. Burke’s initial finding of disc desiccation (loss of water content) at L3-L4, L4-L5, L5-S1 and a change in the T2 signal intensity, signifying a degenerative spinal disc disease. 80 However, he stated that plaintiffs back pain was improving and that the treating physician’s recommendation was continued physical therapy for plaintiffs cervical thoracic strain. 81 Upon being asked to identify which of plaintiffs illnesses have been present for more than one year, Dr. Girzadas listed back pain (present since 1994), balance issues (present since 1999), degenerative disc disease (present since 2004), and mild to moderate stenosis (narrowing of the spine) (present since 2004). 82 Dr. Girzadas noted that these conditions had more than a minimal effect on plaintiffs functioning, but that none of these conditions met or equaled a listing. 83 As far as her RFC, Dr. Girzadas testified that plaintiff had an inability to use ladders, ropes, scaffolds, foot controls or machinery, and to be exposed to heights and vibration. 84 Dr. Girzadas testified that plaintiff could stand or walk for two hours out of an eight hour day but would possibly need to use a cane during that period, walk up stairs or ramps occasionally, and lift ten pounds. 85 Lastly, the ALJ called vocational therapist Pamela Tucker (“VE”) to testify. Before asking for her insights into plaintiffs capacity to work, the ALJ asked her a series of questions that laid a framework within which the VE was to speak about plaintiffs past work experiences and her ability to work despite her medical conditions. 86 First, he asked whether she had heard testimony and had had a chance to review the record. 87 Second, he asked if “the record [was] sufficient for [her] to give [her] impressions as to the past relevant work?” 88 When she responded affirmatively, he asked her to consider “the dictate requirements of the Dictionary of Occupational Titles [“DOT”] as were revised and all of its intended resources” in telling the court about her impressions of plaintiffs work abilities. 89 Finally, he asked her to tell the court about differ *989 enees between her impressions and those of the DOT. 90 The VE classified plaintiffs previous occupational roles as light to medium semiskilled sedentary positions. 91 When plaintiff held positions as a home attendant and subsequently as a mailroom supervisor, she performed medium semi-skilled work. 92 She did light semi-skilled work as a teacher’s aide. 93 The VE suggested that these previous roles had endowed plaintiff with people, analytical, and instructing skills, which could be transferred to perform other types of sedentary semiskilled work. 94 The ALJ asked the VE to comment on whether there were jobs in the national and local economy for people of plaintiffs age with her education, background and impairments. 95 He asked her to take into account the plaintiffs following limitations: her ability to lift, carry, push, or pull ten pounds or less, sit for six out of eight hours in a day, stand for two out of eight hours in a day, walk two out of eight hours in a day possibly with the aid of a cane, and only occasionally reach overhead, balance, stoop, kneel, crouch, crawl, and climb ramps or stairs. 96 He also asked that the VE consider plaintiffs inability to climb ladders, ropes, or scaffolds, use foot or leg controls, or deal with heights, moving machinery, or vibration. 97 Considering all of the mentioned restrictions, the VE opined that plaintiff could work as an information clerk, for which the greater Chicago area had six thousand positions, an interviewer, for which two thousand positions existed, and an authorization clerk, for which one thousand positions existed. 98 IV. ALJ’s January 12, 2007 Decision On January 12, 2007, the ALJ determined that plaintiff was not under a disability as defined in the Social Security Act and therefore was not entitled to any DIB. 99 The ALJ began the five step sequential process by noting under step one that plaintiff had not engaged in substantial gainful activity since December 31, 2003 as defined in 20 C.F.R. § 404.1520(b). 100 Under step two, the ALJ found that plaintiff suffered from a degenerative disc disease, which caused sufficient limitations to her work related functioning and thus qualified as severe per 20 C.F.R. 404.1520(c). 101 He recognized that plaintiff was diagnosed with disc desiccation at the L3-L4, L4-L5 and L5-SI levels in her spine after her DLL 102 However, he did not engage in an analysis to determine whether the onset date of plaintiffs disc desiccation occurred prior to the DLI because he found that plaintiffs aggregate medical impairments — disc desiccation, mitral valve prolapse, anxiety and panic disorder — did not impair her ability to perform work related activities and were, therefore, non-severe within the context of disability insurance. 103 The ALJ found *990 that plaintiff failed the third step of the process as she lacked an impairment or combination of impairments that amounted to one of the impairments listed in 20 C.F.R. § 404(p) Appendix 1, Listing 1.04. 104 The ALJ listed all impairments found in Listing 1.04, which provides: Disorders of the spine (e.g., herniated nucleus pulposus, spinal arachnoiditis, spinal stenosis, osteoarthritis, degenerative disc disease, facet arthritis, vertebral fracture), resulting in compromise of a nerve root (including the cauda equina) or the spinal cord with [either]: evidence of nerve root compression characterized by neuroanatomic distribution of pain, limitation of motion of the spine, motor loss (atrophy with associated muscle weakness or muscle weakness) accompanied by sensory or reflex loss and, if there is involvement of the lower back, positive straight-leg raising test (sitting and supine); or spinal arachnoiditis, confirmed by an operative note or pathology report of tissue biopsy, or by appropriate medically acceptable imaging, manifested by severe burning or painful dysesthesia, resulting in the need for changes in position or posture more than once every 2 hours; or lumbar spinal stenosis resulting in pseudoclaudication, established by findings on appropriate medically acceptable imaging, manifested by chronic nonradicular pain and weakness, and resulting in inability to ambulate effectively. 105 After evaluating the entirety of the record, the ALJ found that plaintiff had a RFC to perform sedentary work. 106 He held that she could lift or carry ten pounds, stand or walk at least two hours in an eight hour day, and sit for six hours in an eight hour day. 107 The ALJ found that plaintiffs other limitations included the use of an assistive device when walking, no use of foot/leg controls, no fine finger manipulation, no climbing ladders, ropes, or scaffolding, and the inability to deal with heights, dangerous moving machinery, or vibration. 108 The ALJ also found that plaintiff could occasionally reach overhead, climb ramps and stairs, balance, stoop, kneel, crouch, and crawl. 109 The ALJ, however, noted that plaintiffs descriptions of her daily activities, including her own personal care and grooming, cooking, and dish-washing, were not those which one would expect of a person complaining of disabling pain. 110 Additionally, he concluded that the medical evidence' — like the March 24, 2004, MRI and the April 12, 2004 physical exam by Dr. Freeman— failed to substantiate plaintiffs subjective complaints of pain. 111 The ALJ noted that the medical evidence provided could reasonably be expected to produce pain, but that plaintiffs statements concerning the intensity, persistence, and debilitating effects of her symptoms were not entirely credible. 112 The ALJ also gave credence to the State Disability Determination Services, who supported a finding of “not disabled.” 113 Finally, the ALJ examined the VE’s testimony in assessing whether plaintiff could make a successful adjustment to other work. 114 The ALJ underscored the legal *991 standard, that “if the claimant can perform all or substantially all of the exertional demands at a given level of exertion, the medical-vocational rules direct a conclusion of either ‘disabled’ or ‘not disabled’ dependant on the claimant’s specific vocational profile.” 115 Defaulting to the VE’s testimony, the ALJ found that the plaintiff possessed occupational skills from her previous work roles that enabled her to adjust to other work that was readily available in the national economy. 116 Based on the VE’s testimony, the ALJ listed positions, which plaintiff could easily assume, including an information clerk with 6,000 jobs existing in the Chicago metropolitan area; an interviewer, with 2,000 jobs existing in the Chicago metropolitan area, and; an authorization clerk, with 1,000 jobs existing in the Chicago metropolitan area. 117 Assessing plaintiffs age, education, work experience, and RFC, the ALJ concluded that plaintiff was capable of performing other work that existed in significant numbers and, thus, was not disabled under the framework of Medical-Vocational Rules 201.21 and 201.14. 118 STANDARD OF REVIEW In disability insurance benefits cases, a court’s scope of review is limited to deciding whether the final decision of the Commissioner of Social Security is based upon substantial evidence and the proper legal criteria. 119 Substantial evidence exists when a “reasonable mind might accept [the evidence] as adequate to support a conclusion.” 120 While reviewing a commissioner’s decision, the Court may not “reweigh evidence, resolve conflicts in the record, decide questions of credibility, or substitute [its] own judgment for that of the Commissioner.” 121 The Court may affirm, modify, reverse or remand the Commissioner’s decision only upon ascertaining that the decision lacks sufficient evidentiary support or is undermined by legal error. 122 SOCIAL SECURITY REGULATIONS The Social Security Act requires all applicants to prove that they are disabled as of their DLI to be eligible for disability insurance benefits. ALJs are required to follow a sequential five-step test to assess whether a claimant is legally disabled: (1) has the claimant engaged in substantial gainful activity; (2) if no, does the claimant have a severe medically determinable impairment or combination of impairments; (3) if yes, is the impairment so severe that it is tantamount to an impairment listed in the social security regulations in impeding the claimant from performing basic work-related activities; (4) if no, can the claimant perform her past relevant work; (5) if no, can the claimant adjust to perform another type of work existing in a significant number of jobs in the national economy? 123 At the fourth and fifth steps of the inquiry, the ALJ is required to evaluate the claimant’s RFC in calculating *992 which work-related activities she is capable of performing given her limitations. 124 An important notion stressed by the Seventh Circuit underlies the RFC analysis: disability insurance income “is not a form of unemployment insurance and is unavailable if any do-able work exists in the national economy, even if other persons with better skills are likely to be hired instead.” 125 ANALYSIS Plaintiff argues that the court should reverse or vacate the ALJ’s decision because the ALJ: (1) relied on suspect factors to discount plaintiffs credibility, (2) neglected to articulate a medical basis for finding that plaintiff had the RFC to perform sedentary work, (3) failed to elicit and address inconsistencies amongst the VE’s testimony and the DOT, (4) improperly held that plaintiffs aptitudes were transferable skills, and (5) improperly weighed medical sources and overlooked unfavorable medical evidence. The Court now examines each of these allegations. A. The ALJ’s Credibility Determination Plaintiff first argues that the ALJ improperly used evidence of her daily activities to discredit her claims regarding the intensity, persistence, and effects of her medical condition. The Commissioner refutes plaintiffs argument by noting that plaintiffs factual allegations conflicted with evidence in the record and that the ALJ has the authority to weigh evidence and resolve inconsistencies amongst testimonies in determining plaintiffs RFC. An ALJ’s credibility determination is entitled to substantial deference and cannot be invalidated unless proven to be patently wrong. 126 Courts accord substantial deference to ALJs’ credibility determinations, because they recognize that ALJs are in “the best position to observe the witness.” 127 Social security regulations mandate ALJs to consider a plaintiffs daily activities; dosage, effectiveness and side-effects of medication taken; type of pain treatment other than medication and; reasons the claimant may not seek treatment for pain. 128 The Seventh Circuit has empirically allowed ALJs to evaluate subjective evidence and their observations during the hearing in assessing the severity of a disability as it relates to RFC. 129 ALJs must provide specific reasons and evidentiary support for their credibility findings so that the parties and subsequent reviewers will know what weight the ALJ gave the plaintiffs statements. 130 That said, the Seventh Circuit has rejected claims that an ALJ failed to provide sufficiently specific reasons for his credibility determination where the ALJ thoroughly evaluated the plaintiffs condition and the record. 131 Here, the ALJ provided sufficient justification for his credibility determination. He did not find plaintiffs subjective complaints about pain to be credible because her daily activities did not appear to *993 be limited to the extent one would expect of someone who lives with “disabling symptoms and limitations.” 132 In her disability report, plaintiff stated that she took care of her own personal care and grooming (with the use of a shower chair), washed dishes while supporting herself on the sink, did laundry (although she could not carry a full laundry basket), and cooked while standing for 20 minutes at a time. 133 The ALJ stated that he tried to further investigate the nature and severity of plaintiffs limitations, particularly the location, duration, and frequency of her symptoms, and the factors that exacerbated the symptoms, as well as the dosage, and side of effects of her treatment. 134 However, he found that the medical evidence did not support plaintiffs subjective complaints of pain. 135 For example, an MRI demonstrated that plaintiffs vertical bodies were well preserved in height and alignment, with no fracture or subluxation in plaintiffs spine. 136 No focal bone marrow signal abnormalities were detected in the MRI. 137 In her April 12, 2004 physical exam, plaintiffs gait was normal and she could heel-to-toe walk easily. 138 Even Dr. Burke noted that plaintiff could lift up to ten pounds and stand or walk for up to two hours. 139 Therefore, it was reasonable for the ALJ to conclude that “while the claimant undoubtedly may experience some pain,” she exaggerated her medical condition. B. The ALJ’s RFC Analysis Plaintiff next argues that the ALJ provided no medical basis for rejecting evidence of her physical limitations and that his RFC determination was, therefore, invalid. According to plaintiff, had the ALJ evaluated medical evidence that she had difficulty maintaining balance, lifting more than five pounds, sitting or walking for prolonged periods, and would require periods of standing, stretching and moving about to work a full eight hour day, he would not have found that she was capable of performing sedentary unskilled work. The Commissioner found that the ALJ sufficiently addressed all of the evidence on record and argues that plaintiff failed to provide compelling evidence showing that the ALJ mis-characterized or overlooked evidence. A claimant’s RFC consists of the activities that can be performed despite one’s physical and mental limitations. 140 In determining RFC, ALJs evaluate the claimant’s age, ability to lift weight, sit, stand, walk, push, pull, and any other factors that would be helpful in gauging the claimant’s ability to perform sedentary, light, medium, heavy or very heavy levels of work. 141 During this process, ALJs are expressly prohibited from acting as doctors and making their own independent medical determinations. 142 Once they have determined a claimant’s RFC, ALJs are expected to minimally articulate reasons for crediting or rejecting evidence of a disability. 143 *994 In finding plaintiff capable of performing sedentary unskilled work, the ALJ complied with social security regulations by articulating both an observational and a medical basis for rejecting plaintiffs subjective claims of pain. First, the ALJ explained that plaintiffs subjective complaints of pain, and her claim that any type of movement would exacerbate her pain, were not entirely credible. 144 Plaintiffs daily activities, including her own personal care, grooming, cooking, and dishwashing, “are not limited to the extent one would expect” of someone experiencing disabling pain. 145 Second, the ALJ found that the medical evidence provided reason to believe that'plaintiff was in pain, but failed to corroborate her claims regarding the intensity, persistence and debilitating effects of her medical condition. 146 Even the MRI from March 24, 2004, displaying plaintiffs lumbar stenosis condition, showed that plaintiffs vertical bodies were well preserved in height and alignment, with no fracture or subluxation noted. 147 There were no focal bone marrow signal abnormalities detected in the MRI. 148 In her April 12, 2004 physical exam, plaintiffs gait was normal and she could heel-to-toe walk easily. 149 Dr. Burke even reported that plaintiff could lift up to ten pounds and stand or walk for up to two hours in an eight hour day. 150 Third, the ALJ also considered the State Disability Determination Services’ finding that plaintiff was “not disabled,” recognizing that its opinion does not carry the same degree of weight as plaintiffs treating and examining physieians. 151 Therefore, the ALJ provided a sufficient basis for his RFC determination. C. The ALJ’s Questioning of the Vocational Expert Plaintiff states that the ALJ did not comport with social security regulations requiring ALJs to affirmatively ask VEs whether their evidence presented conflicts with the DOT. According to plaintiff, the VE testified that plaintiff could perform the work of an interviewer, authorization clerk and information clerk, which do not fall within the light “unskilled jobs” category in the DOT, but the ALJ did not investigate this inconsistency to obtain a reasonable explanation. Plaintiff finds fault in the ALJ’s decision to ask the VE to recognize differences between her impressions of plaintiffs abilities and those of the DOT before she testified, rather than waiting until after she had testified to ask “if the evidence she provided conflicts with information provided in the DOT.” 152 The Commissioner did not find a discrepancy between the VE’s testimony and the DOT. The Commissioner also argues that the VE listed occupations that fall under ‘light skilled’ labor in the DOT by their synonyms, such that plaintiff cannot find the job titles in the DOT even though they are indeed “light skilled” jobs. Consequently, the commissioner argues that the ALJ had no reason to elicit an explanation for the VE’s testimony in the first place. ALJs, who hear testimony from VEs about the requirements of a particular job, have an affirmative duty to inquire about potential conflicts between the VE’s findings and information provided in the DOT. 153 If a VE’s statements appear to *995 conflict with the DOT, the ALJ must investigate the inconsistency. 154 When an inconsistency arises, the ALJ is not required to default to the DOT over the view of a vocational expert. 155 Automatically deferring to the DOT over a VE’s view “would make the [DOT] an independent source of listed impairments, giving the Dictionary’s team of authors a power that Congress has bestowed on the Commissioner of Social Security.” 156 The DOT is only a tool and does not carry any binding force of law. 157 Plaintiffs may raise conflicts between the VE’s testimony and the DOT either during or after the hearing before the ALJ. 158 However, if a plaintiff fails to bring the ALJ’s attention to an inconsistency during the hearing by objecting, then plaintiff can only win a claim that the ALJ insufficiently investigated a conflict by proving that the conflict was obvious enough that the ALJ should have independently recognized it during the hearing. 159 The ALJ satisfied his duty to affirmatively ask whether any inconsistencies between the VE’s testimony and information in the DOT existed. Before allowing the VE to state her opinion as to the plaintiffs RFC with respect to the DOT, he asked her to consider the DOT’s dictates and to highlight any differences. 160 Plaintiff cites an unpublished district court case to support her argument that posing a hypothetical question asking a VE to identify discrepancies between her expert opinion and the DOT prior to her testimony is legally insufficient. 161 However, while recognizing an affirmative duty to inquire into possible discrepancies between a VE’s testimony and the DOT, the Seventh Circuit has not established a singular method by which ALJs must elicit potential conflicts. 162 Therefore, the ALJ satisfied this duty by asking the VE at the onset to describe her findings and to note where she differs from the DOT. The ALJ also did not err in deciding not to further question the VE because plaintiff did not object to the VE’s testimony with respect to plaintiffs ability to work and the inconsistency she now raises is not obvious. The ALJ could not have known that the precise job titles of “interviewer,” and “authorization clerk” do not appear in the DOT. Similarly, it is unlikely that the ALJ would have known that the VE’s testimony conflicted with the DOT because the evidence as a whole suggested that plaintiff had the ability to perform tasks associated with the jobs that the VE listed. The ALJ had already also determined that plaintiff had a college education and that she could read and write. 163 Dr. Spahic-Mihajkovic’s findings — that plaintiff had a very good ability to understand, remember and carry out short and simple instructions, to sustain an ordinary routine without special supervision, to make simple work-related decisions, and to get along with co-workers or peers — also corroborated the VE’s findings. 164 Since plaintiffs counsel did not raise during cross-exami *996 nation of the VE, or at any other point in the hearing, the discrete inconsistency now raised, the ALJ was not required to further investigate the VE’s testimony. Neither the court nor the ALJ has a duty to reopen the record at this time for this issue. 165 D. Interpretation of Transferable Skills In his decision, the ALJ held that plaintiffs people, analytical, and instructing skills constituted transferrable work skills. 166 However, there is some discrepancy concerning whether the VE thought the plaintiff had acquired “instructing” or “constructing” skills. 167 The Court finds that this mistake is merely a typographical error. The Court cannot determine whether the error is on the part of the ALJ, who was present at the August 16, 2006 hearing and conceivably taking notes, or whether the mistake is on the part of the transcriber who made at least two other transcription mistakes in the record before the Court. 168 There is Seventh Circuit precedent that allows the Court to correct this type of scrivener’s error in favor of the ALJ and, thus, the Court has done so here. 169 That said, plaintiff claims that the ALJ erred in holding that her people, analytical, and instructing skills constituted transferrable work skills, rather than aptitudes. Plaintiff also asserts that even if we assume that her people, analytical, and instructing skills are transferable work skills, the ALJ and the VE both failed to explain how those skills could be applied to other jobs. The Commissioner refutes plaintiffs argument by characterizing transferability with respect to DIB as relating to work activities where individuals can develop expert proficiency. The Commissioner further argues that the Sixth Circuit has held that “effective communication, practical thinking, [and] the ability to deal with various people under adverse conditions” are transferable skills for purposes of social security regulations. 170 Social security regulations require an ALJ to identify the claimant’s acquired work skills and the specific occupations to which the acquired work skills are transferable in his decision. 171 Transferable work skills are defined as “practical and familiar knowledge of the principles and processes of an art, science or trade, combined with the ability to apply them in practice in a proper and approved manner” to meet the requirements of other jobs. 172 In contrast, aptitudes refer to an “inclination, a natural ability, talent, or capacity for learning.” 173 The Seventh Circuit has *997 classified basic work activities or aptitudes' — the ability to walk; stand; sit; lift; push; pull; reach; carry; handle; see; hear; speak; understand, execute or remember instructions; use judgment; respond to supervision, and; deal with changes in work setting — -as being distinct from transferrable work skills necessary to perform other jobs. 174 However, neither social security regulations nor Seventh Circuit precedent define instructing or analytical skills as aptitudes as a matter of law. 175 Plaintiffs people skills, instructing skills, and analytical skills can be properly classified as transferrable work skills. In the absence of a clear delineation between work skills and aptitudes in the social security regulations and Seventh Circuit case law on the issue, the court must examine the nature of plaintiffs former position and the positions that the ALJ contends plaintiff can perform despite her limitations to determine whether the skills named are indeed transferable work skills. It would seem that people, instructing, and analytical skills are the very skills that can be acquired from a sedentary supervisory position and transferred to another sedentary supervisory role. An individual can develop expert instructional and people skills by undergoing managerial training or holding a supervisory role. Furthermore, the DOT specifies that: “analyzing needs and product requirements” and “teaching others how to do something” are work skills required to perform the duties of an employment interviewer; 176 “using logic and analysis to identify the strengths and weaknesses of different approaches” and “teaching others how to do something” are work skills necessary to perform the duties of an information clerk 177 and; “using logic and analysis to identify the strengths and weaknesses of different approaches” and “evaluating the likely success of an idea in relation to the demands of the situation” are skills essential to perform the duties of a cash accounting clerk, who is responsible for preparing payroll and authorizing expenditures. 178 It is evident that plaintiffs analytical, instructing, and people skills would enable her to perform other sedentary unskilled positions. Plaintiff cites Key v. Sullivan to support the proposition that ALJs must explain how a person’s skills are transferable to other jobs. 179 However, Key does not establish a sweeping rule that ALJs must always explain how work skills are transferrable to other positions. In Key, the Court determined that the ALJ failed to “identify work skills actually acquired” by the plaintiff. 180 The matter at hand is inapposite. As the Court has just explained, it is evident that plaintiffs previ *998 ous jobs endowed her with the people, instructing, and analytical skills listed by the ALJ. SSR 82-41 requires that the ALJ identify a claimant’s acquired work skills, and specific occupations to which the acquired work skills are transferable. 181 The ALJ has done this. SSR 82-41 does not require, as the plaintiff argues, that the ALJ describe how the skills transfer to these jobs. The ALJ fully complied with the requirements of the social security regulations by listing the claimant’s transferable skills and the jobs to which they could be applied. The ALJ first acknowledged that plaintiff acquired people skills, instructing skills, and analytical skills from her previous sedentary positions that prepared her well for other sedentary occupations that existed in significant numbers in the national economy. 182 He subsequently stated that given her age, education, work experience, and RFC, plaintiff could perform the requirements of representative occupations such as an interviewer, an information clerk, and an authorization clerk. 183 Therefore, the ALJ did not err in finding that plaintiff had transferrable work skills. E. The ALJ’s Evaluation of the Medical Evidence on Record Lastly, plaintiff argues that the ALJ failed to evaluate all of the medical evidence on record at stage three of the sequential evaluation because the ALJ failed to analyze or address the opinions of Dr. Burke. The Commissioner responds by arguing that Dr. Burke is incapable of commenting on plaintiffs medical state before plaintiffs DLI because she became the plaintiffs primary care physician two months after the DLI and presented no medical evidence suggesting that her findings were illustrative of plaintiffs condition prior to 2004. The Commissioner also argues that the ALJ properly decided not to grant equal weight to all of the medical evidence considering there were many inconsistencies amongst the evidence on record. The ALJ is not afforded unlimited judicial deference but, rather, the ALJ must, in addition to relying on substantial evidence, articulate his or her analysis at some minimal level. 184 Although “[i]t is a basic obligation of the ALJ to develop a full and fair record,” the ALJ “need not evaluate in writing every piece of evidence in the record,” as long as he or she provides a “logical bridge” between the conclusion and the evidence on the record. 185 With respect to medical source evidence, the ALJ’s decision in this case does not reflect a thorough evaluation of the evidence as a whole because the ALJ failed to articulate a basis for rejecting the opinions of Dr. Burke. Disappointingly, the ALJ never cited to the opinions of Dr. Burke in his decision and, therefore, it is impossible to tell whether the ALJ examined them at all. 186 Social security regulations require ALJs to grant controlling weight to physicians’ opinions pertaining to the nature and severity of a claimant’s medical condi *999 tion when the medical findings comport with substantial evidence on record. 187 Unless ALJs give a treating source’s opinion controlling weight, they must evaluate six criteria in deciding how much weight to afford a medical opinion: (1) the nature and duration of the examining relationship; (2) the length and extent of the treatment relationship; (3) the extent to which medical evidence supports the opinion; (4) the degree to which the opinion is consistent with the entire record; (5) the physician’s specialization if applicable; and (6) other factors which validate or contradict the opinion. 188 Here, the ALJ did not give Dr. Burke, one of plaintiffs treating sources, controlling weight, but then failed to articulate his reasoning. From the parties briefs and the record, this appears to be a case of “dueling doctors” where the ALJ must evaluate and resolve a conflict between the opinions of two treating physicians. 189 In the case of dueling doctors, “medical evidence, especially that from a treating physician, ‘may be discounted if it is internally inconsistent or inconsistent with other evidence’ in the record.” 190 In this case, the inconsistency is that the ALJ chose to discuss and give weight to one of plaintiffs treating physician’s opinions, who saw plaintiff after her DLI, but not the other treating physician who also saw her after her DLI. The ALJ stated that he afforded controlling weight to Dr. Spahic-Mihajkovic’s Mental Impairment evaluation of plaintiff, but provides no discussion or mention of Dr. Burke’s evaluations. The Commissioner is correct that the opinions of both Dr. Burke and Dr. Spahic-Mihajkovic do not relate back to the period prior to plaintiffs DLI and, thus, neither opinion may be particularly probative of plaintiffs condition during the relevant time period. However, the ALJ was still required to articulate his analysis of Dr. Burke’s opinion, at least at some minimal level, especially in light of 20 C.F.R. § 404.1527, which states that the SSA “will always give good reasons in our notice of determination or decision for the weight we give your treating source’s opinion.” 191 Further, although the timing of Dr. Burke’s reports may have been a reason to discount them, it does not justify ignoring Dr. Burke’s opinions in their entirety without explanation, especially since the ALJ relied on the report of Dr. Spahie-Mihajkovic, which was generated after Dr. Burke’s reports. 192 Dr. Burke became Plaintiffs primary care physician after plaintiffs DLI, and submitted both her BDDS report and her report to plaintiffs counsel eight months after beginning a treating relationship with the plaintiff. 193 As the Commissioner points out, the job of the ALJ was to determine whether plaintiff had a disability that existed prior to the expiration of plaintiffs insured status, ie. December 31, 2003, and Dr. Burke’s reports clearly postdated plaintiffs DLI. 194 In Eichstadt v. *1000 Astrue, the Seventh Circuit addressed evidence that post-dated the plaintiffs DLI, and noted that although that evidence tended to suggest that the plaintiff was currently disabled, it provided no support for the proposition that the plaintiff was disabled at any time prior to the date last insured. 195 Here, we have a similar situation, in that Dr. Burke’s reports in the record directly precede a note from the SSA documenting its failed efforts to obtain medical records from the time period between 1998 and 2004, which could have substantiated that plaintiff had a documented disability before plaintiffs DLI. 196 Consequently, in light of the above, the ALJ may have been justified in deciding that Dr. Burke’s opinions were unworthy of being given controlling weight but, even if that were to have been the ALJ’s reasoning, that analysis still needed to be stated. 197 Therefore, we remand this matter for, if nothing more, further analysis and explanation as to the weight, if any, given to Dr. Burke’s opinions and reports. Put another way, if the ALJ rejected Dr. Burke’s opinion, that needed to be articulated. CONCLUSION For the reasons set forth above, the Court finds that the ALJ’s January 12, 2007 decision lacks evidence of a fully developed record. Accordingly, the Court grants plaintiffs motion to remand [dkt. 25] and denies the Commissioner’s motion to affirm [dkt. 31]. This matter is hereby remanded for further evaluation and explanation regarding the opinions of Dr. Burke. IT IS SO ORDERED Footnotes [1] R. 14. [2] R. 100. [3] R. 14. [4] R. 103. [5] R. 104.
