Charles R. Sexton v. Director, Office of Workers' Compensation Programs

752 F.2d 213 Charles R. SEXTON, Petitioner, v. DIRECTOR, OFFICE OF WORKERS' COMPENSATION PROGRAMS, Respondent. No. 84-3093. United States Court of Appeals, Sixth Circuit. Argued Dec. 6, 1984. Decided Jan. 11, 1985. Lewis Seiler, Cincinnati, Ohio, for petitioner. Benefits Review Board, Ronald G. Ray (argued), J. Michael O'Neill, U.S. Dept. of Labor, Washington, D.C., for respondent. Before EDWARDS and KENNEDY, Circuit Judges, and PHILLIPS, Senior Circuit Judge. GEORGE CLIFTON EDWARDS, Jr., Circuit Judge. — 1 — Claimant Charles R. Sexton filed a claim for benefits under the Black Lung Benefits Act, 30 U.S.C. Sec. 901 et seq., on April 26, 1979. The ALJ, after a hearing, denied benefits on July 1, 1982, and the Board affirmed by Decision and Order December 5, 1983. — 2 — Claimant is now a 61-year old man. He has an eighth grade education. His work history includes employment at three different coal companies in Kentucky and Ohio. While his work history at coal mining is significantly less extensive than in most such cases, his description of his exposure which is undisputed in this record, bears repetition. As quoted in the transcript of the hearing in this case, it is as follows: — 3 — [Sexton]: The job was--I was a slate picker up in the tipple. There's about approximately 65, 70 feet up in the air where all the coal come off the barges, come up in the tipple. As it come into the tipple, there was just like this platform made here. There are three to four men sitting on each side of this big shaker that was in the back. It divided the dust, the lump and the slate as it come down this four foot belt, and it had two windows in it. That's all we had in that room. — 4 — The room was around, approximately 20 by 30, or something like that, your Honor, and we wore bandannas, red bandannas and blue bandannas over our noses and our eyes. We got them down like that to keep from sucking all that dust down into our stomach, and if you happen to eat a sandwich in there, a peanut butter sandwich or egg, if you take a bite of that sandwich and then if you happen to look down at the sandwich, there would be nothing but a big ring around where you took the bite. That's how much dust was in that one room. — 5 — Then, if you got too much dust in you, you push a red button and you go to the door and that guy--the foreman would send another man in and then you would go down on the railroad tracks and take a breather there, see. You throw the lumps of coal up in the boxcars. That went on like that. — 6 — * * * — 7 — * * * — 8 — Q. You indicated that you wore a bandanna over your face? — 9 — [Sexton]: Yes. — 10 — Q. What was the reason for that? — 11 — [Sexton]: Well, see, to keep the dust, you know, in your mouth--going down in your mouth and nose, and every once in a while you would step onto the outside and shake that bandanna out and come back in and put it back on your face. — 12 — * * * — 13 — * * * — 14 — Q. Did you ever [get] sick from the dust at all? — 15 — [Sexton]: Yes, sure. You had to go out. — 16 — Q. What kind of sickness would it be? — 17 — [Sexton]: Just spitting up that coal dust, you know, blowing your nose. — 18 — Q. Would it make you sick to your stomach? Would it make you feel nauseous? — 19 — [Sexton]: Oh, yes. You did get dizzy. — 20 — Q. Was that daily? — 21 — [Sexton]: Just about. — 22 — Tr. 8-12. — 23 — Claimant's testimony was that he worked for two years at Raymond City Coal Company in North Bend, Ohio, under this exposure. He had previously worked another year at Chevrolet Coal Mining Company in Harlan, Kentucky. He finally had to quit work at a non-coal related job in 1976 because of breathing problems. — 24 — The significant testimony in this case from the claimant's point of view is that of Dr. Robert Penman, Director of Pulmonary Medicine at Bethesda Hospital in Cincinnati, Ohio. Dr. Penman examined the claimant twice and wrote three reports which are as follows: 1. June 8, 1979 History: — 25 — * * * — 26 — * * * — 27 — He has been increasingly short of breath since 1946. He is now breathless on any exertion greater than walking on the level at a normal pace. He wheezes a lot and complains of pain in his chest at times. He has a cough productive of copious sputum. There is no previous history of chest illness or any other illness of note. He now smokes 2 or 3 cigarettes a day, used to smoke up to 1/2 pack of cigarettes daily until quite recently. He is receiving disability from the Veterans Authority for 23 years and is on Social Security Benefits since 1974. — 28 — Examination : Chest moves well with respiration. Breath sounds are normal but there are coarse rales at both lung bases. Cardiovascular examination shows no abnormality. Blood pressure, 140/85. — 29 — Chest X-ray : This shows fine nodulation in the lower and mid-zones of both lungs consistent with pneumoconiosis stage I (Cincinnati, 1/1 p). — 30 — Lung Function Tests : These show no abnormality. Vital capacity is normal (4.4 liters, predicted = 5.0 +/- 1.0). Expiratory flow is normal (FEV 1 = 3.3 liters = 75% of VC). — 31 — Conclusion : There is a history of exposure to coal mine dust and other dusts which maybe [sic] adequate for a diagnosis of pneumoconiosis. The X-ray is certainly suggestive of that diagnosis stage I. Lung function is not impaired. 2. August 4, 1980 History: — 32 — * * * — 33 — * * * — 34 — He has been increasingly short of breath since 1946 and is now breathless on any exertion greater than walking on the level at a normal pace. He wheezes and complains of pain in his chest at times. He has a cough productive of copious sputum. There is no previous history of chest illness or any other illness of note. He has now quit smoking since June of 1979, previously two or three cigarettes a day, had smoked up to 1/2 pack of cigarettes daily for many years. He receives disability benefits from Veterans Authority and has Social Security Benefits. — 35 — Examination : Chest moves well with respiration. There are minor wheezes at both lung bases and some coarse rales. Cardiovascular examination is normal. Blood pressure, 125/85. — 36 — Chest X-ray : This shows fine nodulation in the lower and mid-zones of both lungs consistent with pneumoconiosis stage I (Cincinnati, 1/1 p). — 37 — Lung Function Tests : These show some airway obstruction. Vital capacity is bormal [sic] (5.2 liters, predicted = 4.8). Expiratory flow is reduced (FEV 1 = 3.2 liters = 62% of VC). Arterial blood gases show no abnormality. PO2 is 85. Exercise test was attempted but after one minute of walking on the treadmill at 2 miles an hour the patient complained of weakness and faintness and the test had to be terminated at that time. — 38 — Conclusion : Although the history of exposure to coal mine dust and other dust maybe [sic] adequate there is a definite abnormality on the chest X-ray consistent with pneumoconiosis stage I. Lung function is impaired. 3. January 5, 1981 United States Department of Labor Employment Standards Administration 121 E. State Street Columbus, Ohio 43215 Re: Charles Sexton To Whom It May Concern — 39 — Mr. Sexton does in fact have black lung disease, and it has been caused at least in part by coal mining work, and because of the black lung disease Mr. Sexton is totally disabled. — 40 — Yours sincerely, — 41 — [s/ ] Robert W. Penman, M.D. — 42 — In addition to Dr. Penman's report, Dr. William Anderson examined claimant on November 12, 1979, and found that an x-ray indicated 1/1 pneumoconiosis. — 43 — The ALJ's denial of black lung benefits is founded upon a report by Dr. C.D. Smith, who is a Board-certified radiologist and B-reader1 but who did not examine claimant. As Congress has required in the Black Lung Benefits Act, the negative reading of an X-ray does not mean that the person to whom the X-ray applies does not have pneumoconiosis. 30 U.S.C. Sec. 923(b).2 — 44 — We hold that the ALJ and the Board erred in giving greater weight to a non-examining doctor's negative reading of a single X-ray than to the results of examinations and X-ray readings by two qualified physicians. This is particularly true since one of the doctors finding pneumoconiosis, Dr. Penman, possesses qualifications which appear to equal or exceed those of any physician ever cited to this court as a witness on pulmonary diseases. See Appendix, infra. — 45 — As another panel of this court has recently recognized: — 46 — It is well-established that a single positive X-ray can trigger the presumption in favor of a claimant, and the Secretary cannot rebut that presumption merely by presenting the results of a negative reinterpretation of the same X-ray. See e.g., Haywood v. Secretary, 699 F.2d 277, 283 and 285 (6th Cir.1983); Smith v. Califano, 682 F.2d 583, 587 (6th Cir.1982); Lawson v. Secretary, 688 F.2d 436, 438 (6th Cir.1982); Miniard v. Califano, 618 F.2d 405, 410 (6th Cir.1980); Singleton v. Califano, 591 F.2d 383, 385 (6th Cir.1979); Cunningham v. Califano, 590 F.2d 635 (6th Cir.1978); Dickson v. Califano, 590 F.2d 616, 623 (6th Cir.1978); Burchett v. Mathews, 575 F.2d 1189, 1191 (6th Cir.1978); Ansel v. Weinberger, 529 F.2d 304, 309-310 (6th Cir.1976). — 47 — Hatfield v. Secretary of Health and Human Services, 743 F.2d 1150, 1155 (6th Cir.1984). — 48 — The judgment of the Benefits Review Board is reversed and the case is remanded for the award of black lung benefits.

KENNEDY, Circuit Judge, dissenting. — 133 — I respectfully dissent. — 134 — Claimant worked only three years in the mines and accordingly is not entitled to any presumption. The ALJ found that claimant had not established that he suffers from pneumoconiosis or has a disabling respiratory or pulmonary complaint arising out of his brief period of coal mine employment in the early 1940's. He was engaged in other employment until 1974. The Benefits Review Board determined that the ALJ's decision is supported by substantial evidence. I agree. — 135 — The ALJ found that claimant did not establish pneumoconiosis by x-ray. The x-rays on which he relied, and upon which Dr. Penman relied for his diagnosis, were reread by a "B" reader and found completely negative for pneumoconiosis. The ALJ was entitled as the factfinder to accord more weight to the "B" reader. Peabody Coal Co. v. Benefits Review Board, 560 F.2d 797, 802 (7th Cir.1977). — 136 — The ALJ was also entitled to give little or no weight to Dr. Penman's conclusion that claimant is disabled from pneumoconiosis. Dr. Penman was not shown to be an attending physician. The record reflects only that he examined claimant on two occasions. Blood gas studies and pulmonary function studies were normal. The only objective findings he made were that claimant had minor wheezes at both lung bases and some coarse rales, and some airway obstruction. It was not until five months later, without examining claimant again, that Dr. Penman stated that he was totally disabled by black lung disease. The ALJ as the factfinder was entitled to find that Dr. Penman's reports were inconsistent. — 137 — Although I might as the factfinder have accepted Dr. Penman's opinion, I cannot say that the ALJ was compelled to accept it. — 138 — Accordingly, I would affirm the decision of the Benefits Review Board. Footnotes [1] A "B-reader" is one who has passed an examination testing his proficiency in detecting the presence of pneumoconiosis in chest x-rays. The test is administered by the Appalachian Laboratory for Occupational Safety and Health as provided in 42 C.F.R. Sec. 37.51 [2] "In carrying out the provisions of this part, the Secretary shall to the maximum extent feasible (and consistent with the provisions of this part) utilize the personnel and procedures he uses in determining entitlement to disability insurance benefit payments under section 223 of the Social Security Act, but no claim for benefits under this part shall be denied solely on the basis of the results of a chest roentgenogram. In determining the validity of claims under this part, all relevant evidence shall be considered, including, where relevant, medical tests such as blood gas studies, X-ray examination, electrocardiogram, pulmonary function studies, or physical performance tests, and any medical history, evidence submitted by the claimant's physician, or his wife's affidavits, and in the case of a deceased miner, other appropriate affidavits of persons with knowledge of the miner's physical condition, and other supportive materials."
