20 C.F.R. §§ 220.177–220.180

Medical improvement. Medical improvement is any decrease in the medical severity of an impairment(s) which was present at the time of the most recent favorable medical decision that the annuitant was disabled or continued to be disabled. A determination that there has been a decrease in medical severity must be based on a comparison of prior and current medical evidence showing changes (improvement) in the symptoms, signs or laboratory findings associated with the impairment(s).

Medical improvement not related to ability to do work. Medical improvement is not related to the annuitant's ability to work if there has been a decrease in the severity of the impairment(s) (as defined in paragraph (a) of this section) present at the time of the most recent favorable medical decision, but no increase in that annuitant's functional capacity to do basic work activities as defined in paragraph (d) of this section. If there has been any medical improvement in an annuitant's impairment(s), but it is not related to the annuitant's ability to do work and none of the exceptions applies, the annuity will be continued.

Medical improvement that is related to ability to do work. Medical improvement is related to an annuitant's ability to work if there has been a decrease in the severity (as defined in paragraph (a) of this section) of the impairment(s) present at the time of the most recent favorable medical decision and an increase in the annuitant's functional capacity to do basic work activities as discussed in paragraph (d) of this section. A determination that medical improvement related to an annuitant's ability to do work has occurred does not, necessarily, mean that such annuitant's disability will be found to have ended unless it is also shown that the annuitant is currently able to engage in substantial gainful activity as discussed in paragraph (e) of this section.

Ability to engage in substantial gainful activity. In most instances, the Board must show that the annuitant is able to engage in substantial gainful activity before stopping his or her annuity. When doing this, the Board will consider all of the annuitant's current impairments not just that impairment(s) present at the time of the most recent favorable determination. If the Board cannot determine that the annuitant is still disabled based on medical considerations alone (as discussed in §§ 220.110 through 220.115), it will use the new symptoms, signs and laboratory findings to make an objective assessment of functional capacity to do basic work activities (or residual functional capacity) and will consider vocational factors. See §§ 220.120 through 220.134.

Evidence and basis for the Board's decision. The Board's decisions under this section will be made on a neutral basis without any initial inference as to the presence or absence of disability being drawn from the fact that the annuitant had previously been determined to be disabled. The Board will consider all of the evidence the annuitant submits. An annuitant must give the Board reports from his or her physician, psychologist, or others who have treated or evaluated him or her, as well as any other evidence that will help the board determine if he or she is still disabled (see § 220.45). The annuitant must have a good reason for not giving the Board this information or the Board may find that his or her disability has ended (see § 220.178(b)(2)). If the Board asks the annuitant, he or she must contact his or her medical sources to help the Board get the medical reports. The Board will make every reasonable effort to help the annuitant in getting medical reports when he or she gives the Board permission to request them from his or her physician, psychologist, or other medical sources, Every reasonable effort means that the Board will make an initial request and, after 20 days, one follow-up request to the annuitant's medical source to obtain the medical evidence necessary to make a determination before the Board evaluates medical evidence obtained from another source on a consultative basis. The medical source will have 10 days from the follow-up to reply (unless experience indicates that a longer period is advisable in a particular case). In some instances the Board may order a consultative examination while awaiting receipt of medical source evidence. Before deciding that an annuitant's disability has ended, the Board will develop a complete medical history covering at least the preceding 12 months (See § 220.45(b)). A consultative examination may be purchased when the Board needs additional evidence to determine whether or not an annuitant's disability continues. As a result, the Board may ask the annuitant, upon the Board request and reasonable notice, to undergo consultative examinations and tests to help the Board determine whether the annuitant is still disabled (see § 220.50). The Board will decide whether or not to purchase a consultative examination in accordance with the standards in §§ 220.53 through 220.54.

Point of comparison. For purposes of determining whether medical improvement has occurred, the Board will compare the current medical severity of that impairment(s), which was present at the time of the most recent favorable medical decision that the annuitant was disabled or continued to be disabled, to the medical severity of that impairment(s) at that time. If medical improvement has occurred, the Board will compare the annuitant's current functional capacity to do basic work activities (i.e., his or her residual functional capacity) based on this previously existing impairment(s) with the annuitant's prior residual functional capacity in order to determine whether the medical improvement is related to his or her ability to do work. The most recent favorable medical decision is the latest decision involving a consideration of the medical evidence and the issue of whether the annuitant was disabled or continued to be disabled which became final.

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.

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.

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:

First group of exceptions to medical improvement. The law provides for certain limited situations when the annuitant's disability can be found to have ended even though medical improvement has not occurred, if he or she can engage in substantial gainful activity. These exceptions to medical improvement are intended to provide a way of finding that the annuitant is no longer disabled in those limited situations where, even though there has been no decrease in severity of the impairment(s), evidence shows that the annuitant should no longer be considered disabled or never should have been considered disabled. If one of these exceptions applies, the Board must also show that, taking all of the annuitant's current impairment(s) into account, not just those that existed at the time of the Board's most recent favorable medical decision, the annuitant is now able to engage in substantial gainful activity before his or her disability can be found to have ended. As part of the review process, the annuitant will be asked about any medical or vocational therapy that he or she has received or is receiving. Those answers and the evidence gathered as a result as well as all other evidence, will serve as the basis for the finding that an exception applies.

Second group of exceptions to medical improvement. In addition to the first group of exceptions to medical improvement, the following exceptions may result in a determination that the annuitant is no longer disabled. In these situations the decision will be made without a determination that the annuitant has medically improved or can engage in substantial gainful activity.

Is the annuitant engaging in substantial gainful activity? If he or she is (and any applicable trial work period has been completed), the Board will find disability to have ended (see § 220.179(a)(5));

If the annuitant is not engaging in substantial gainful activity, does he or she have an impairment or combination of impairments which is medically disabling? If the annuitant's impairment(s) is medically disabling, his or her disability will be found to continue;

If the annuitant's impairment(s) is not medically disabling, has there been medical improvement as defined in § 220.177(a)? If there has been medical improvement as shown by a decrease in medical severity, see step (d). If there has been no decrease in medical severity, then there has been no medical improvement; (See step (e));

If there has been medical improvement, the Board must determine whether it is related to the annuitant's ability to do work in accordance with paragraphs (a) through (d) of § 220.177, (i.e., whether or not there has been an increase in the residual functional capacity based on the impairment(s) that was present at the time of the most recent favorable medical determination). If medical improvement is not related to the annuitant's ability to do work, see step (e). If medical improvement is related to the annuitant's ability to do work, see step (f);

If the Board found at step (c) that there has been no medical improvement or if it found at step (d) that the medical improvement is not related to the annuitant's ability to work, the Board considers whether any of the exceptions in § 220.178 apply. If none of them apply, disability will be found to continue. If one of the first group of exceptions to medical improvement applies, see step (f). If an exception from the second group of exceptions to medical improvement applies, disability will be found to have ended. The second group of exceptions to medical improvement may be considered at any point in this process;

If medical improvement is shown to be related to the annuitant's ability to do work or if one of the first group of exceptions to medical improvement applies, the Board will determine whether all of the annuitant's current impairments in combination are severe. This determination will consider all current impairments and the impact of the combination of those impairments on the ability to function. If the residual functional capacity assessment in step (d) above shows significant limitation of ability to do basic work activities, see step (g). When the evidence shows that all current impairments in combination do not significantly limit physical or mental abilities to do basic work activities, these impairments will not be considered severe in nature, and the annuitant will no longer be consider to be disabled;

If the annuitant's impairment(s) is severe, the Board will assess his or her current ability to engage in substantial gainful activity. That is, the Board will assess the annuitant's residual functional capacity based on all of his or her current impairments and consider whether he or she can still do work that was done in the past. If he or she can do such work, disability will be found to have ended; and

If the annuitant is not able to do work he or she has done in the past, the Board will consider one final step. Given the residual functional capacity assessment and considering the annuitant's age, education and past work experience, can he or she do other work? If the annuitant can do other work, disability will be found to have ended. If he or she cannot do other work, disability will be found to continue.
