Donald L. Lanning appeals to this Court from a decision of the United States District Court for the Western District of Missouri affirming the decision of the Secretary that Lanning is not entitled to social security benefits because he retains the residual functional capacity for sedentary work. We have carefully reviewed the record and conclude that we have no alternative but to remand to the administrative law judge (AU) for further proceedings. The principal reason for this decision is that the AU did not properly indicate who had the burden of proof in assessing whether Lanning was able to perform any substantial gainful activity.
Lanning turned 55 in 1983, the year in which the administrative hearing was held. He worked as a police officer and security guard from 1960 to 1980. In August of 1980, Lanning was forced to retire due to heart problems; in November of that year, he underwent triple heart bypass surgery. It is conceded by the Secretary and the AU that Lanning is unable to perform his past relevant work as police officer, detective and security guard. The question, thus, is whether Lanning can perform other work. The AU found that he could perform sedentary work. In making this decision, the AU did not properly indicate who had the burden of proof. This Court has consistently held that if the claimant is not able to return to his former job, the burden of proof shifts to the Secretary to establish that there is other work in the national economy that he can perform.
See e.g., Holland v. Heckler,
In light of the fact that we must remand for further administrative proceedings, we think it important to comment on additional matters. The AU found that although Lanning’s testimony regarding his limitations and pain was credible to the extent that he claimed an inability to perform his past relevant work, it was not credible to the extent of any inability to perform certain sedentary work. The AU, however, failed to make an express credibility determination detailing why he rejected Lanning’s testimony, as required by this Court.
See O’Leary v. Schweiker,
The AU also failed to give full consideration to the report of Dr. Devins, Lanning’s treating physician. Dr. Devins reported that both he and the cardiologist believed that Lanning was totally disabled due to continuing chest and leg pains and lethargy despite surgery and the use of the following drugs: Diazide, Inderol, Procardia, La-six and Coumadin. Dr. Devins’s reports stated that Lanning suffered from arteriosclerotic heart disease, angina pectoris with crushing chest pain, shortness of breath, fatigue, deep venous incompetency, and stasis dermatitis. The AU disregarded this medical opinion, basing his determination on a consulting physician’s report. This latter report did not address Lanning’s ability to perform sedentary work. It did, however, state that Lanning’s impairments might prevent employment in a strenuous occupation, and would prevent “Lanning from lifting more than 40 lbs of weight or climbing more than one flight of stairs in performing his duties.” This Court has stated that “the report of a consulting physician who examined that claimant once does not constitute ‘substantial evidence’ upon the record as a whole, especially when contradicted by the evaluation of the claimant’s treating physician.”
Hancock v. Secretary of Dept. of Health, Education and Welfare,
In order for the AU to find that Lanning is able to perform sedentary work, he must find that such work is
“realistically
within the physical and mental capabilities of the claimant.”
See McMillian v. Schweiker,
Accordingly, we reverse and remand for further proceedings consistent with this decision.
Notes
. In the case of sedentary work, this entails lifting up to 10 pounds at a time and occasionally lifting and carrying files, ledgers and small tools. Although it generally involves sitting, a certain amount of walking and standing is often required. See 20 C.F.R. § 404.1567(a) (1983).
