(a) General. Paragraphs (a), (b), and (c) of §220.177 discuss what is meant by medical improvement, medical improvement not related to the ability to work and medical improvement that is related to the ability to work. How the Board will arrive at the decision that medical improvement has occurred and its relationship to the ability to do work, is discussed in paragraphs (b) and (c) of this section.

(b) Determining if medical improvement is related to ability to work. If there is a decrease in medical severity as shown by the symptoms, signs and laboratory findings, the Board then must determine if it is related to the annuitant's ability to do work. In §220.177(d) the relationship between medical severity and limitation on functional capacity to do basic work activities (or residual functional capacity) and how changes in medical severity can affect the annuitant's residual functional capacity is explained. In determining whether medical improvement that has occurred is related to the annuitant's ability to do work, the Board will assess the annuitant's residual functional capacity (in accordance with §220.177(d)) based on the current severity of the impairment(s) which was present at that annuitant's last favorable medical decision. The annuitant's new residual functional capacity will then be compared to the annuitant's residual functional capcity at the time of the Board's most recent favorable medical decision. Unless an increase in the current residual functional capacity is based on changes in the signs, symptoms, or laboratory findings, any medical improvement that has occurred will not be considered to be related to the annuitant's ability to do work.

(c) Additional factors and considerations. The Board will also apply the following in its determinations of medical improvement and its relationship to the annuitant's ability to do work:

(1) Previous impairment was medically disabling. If the Board's most recent favorable decision was based on the fact that the annuitant's impairment(s) at that time was medically disabling, an assessment of his or her residual functional capacity would not have been made. If medical improvement has occurred and the current severity of the prior impairment(s) is no longer medically disabling based on the standard (see §220.100(b)(3)) applied at the time of that decision, the Board will find that the medical improvement was related to the annuitant's ability to work. If the medical findings support impairment(s) that is currently so severe as to be medically disabling, the annuitant is deemed, in the absence of evidence to the contrary, to be unable to engage in substantial gainful activity. If there has been medical improvement to the degree that the impairment(s) is not currently medically disabling, then there has been medical improvement related to the annuitant's ability to work. The Board must, of course, also establish that the annuitant can currently engage in gainful activity before finding that his or her disability has ended.

(2) Prior residual functional capacity assessment made. The residual functional capacity assessment used in making the most recent favorable medical decision will be compared to the residual functional capacity assessment based on current evidence in order to determine if an annuitant's functional capacity for basic work activities has increased. There will be no attempt made to reassess the prior residual functional capacity.

(3) Prior residual functional capacity assessment should have been made, but was not. If the most recent favorable medical decision should have contained an assessment of the annuitant's residual functional capacity (i.e., his or her impairment(s) was not medically disabling) but does not, either because this assessment is missing from the annuitant's file or because it was not done, the Board will reconstruct the residual functional capacity. This reconstructed residual functional capacity will accurately and objectively assess the annuitant's functional capacity to do basic work activities. The Board will assign the maximum functional capacity consistent with an allowance.

(4) Impairment subject to temporary remission. In some cases the evidence shows that the annuitant's impairment(s) are subject to temporary remission. In assessing whether medical improvement has occurred in annuitants with this type of impairment(s), the Board will be careful to consider the longitudinal history of the impairment(s), including the occurrence of prior remission, and prospects for future worsenings. Improvement in such impairment(s) that is only temporary, i.e., less than 1 year, will not warrant a finding of medical improvement.

(5) Prior file cannot be located. If the prior file cannot be located, the Board will first determine whether the annuitant is able to now engage in substantial gainful activity based on all of his or her current impairments. (In this way, the Board will be able to determine that his or her disability continues at the earliest point without addressing the often lengthy process of reconstructing prior evidence.) If the annuitant cannot engage in substantial gainful activity currently, his or her disability will continue unless one of the second group of exceptions applies (see §220.179(b)).
