DI 28015.005 Two Mechanisms to Relate Medical Improvement (MI) to the Ability to Work
Two different mechanisms may apply in deciding if MI relates to the ability to work. The basis for the comparison point decision (CPD) determines which mechanism applies.
If CPD determination was based on the impairment(s) meeting or equaling a listing, use the prior listing mechanism to determine if there has been medical improvement. Consider whether the CPD impairment still meets or equals that prior listing.
NOTE: Consider the “MI related” step if the Disability Determination Services (DDS) finds at the “meets/equals” step that the impairment(s) does not meet or equal any current listing. If the impairment(s) does not meet or equal any current listing, it cannot meet or equal the CPD listing either, unless the CPD listing is no longer current (i.e., it has been changed or deleted). Thus, the “prior listing” mechanism of the “MI related” step may determine the outcome of the continuing disability review (CDR) where the CPD listing is no longer current.
If we based the CPD determination on medical-vocational factors using an RFC assessment, use the RFC comparison mechanism to determine if there has been MI related to the ability to work. Compare the CPD residual functional capacity (RFC) and medical improvement review standard (MIRS) RFC to determine whether improvement is related to the ability to work.
For more information on using this mechanism, see DI 28015.300 through DI 28015.320.
A. Exhibit for deciding which mechanism to use for relating MI to the ability to work
If the CPD was based on:
Then, decide whether MI is related to the ability to work
Meet or equal a listing of impairments
Consider whether the prior listing is currently met or equaled.
You can consider all CPD sub-sections (EXAMPLE: If previously met listing 5.05A consider 5.05A, 5.05B, 5.05C).
Compare CPD RFC and MIRS RFCs
When assessing MIRS RFC, consider only impairments present at the time of CPD.
No MI (related) or
Use 1. or 2. in this table, as appropriate, depending on the basis for the most recent pre-CPD favorable medical decision, which was made on a basis other than “no MI.”
If we based the CPD on “no MI,” document in the file that the prior CPD RFC still applies. See DI 28015.850 for more information
NOTE: If we originally allowed an adult as a Title XVI child, and there has been no age-18 disability redetermination, see DI 28005.003.
For additional information regarding Public Law 104-193, see DI 23570.001.
B. Decide which mechanism applies
1. No change or no MI in CPD
Reference DI 28015.005A in the chart in this section, and if there is no change or no change to MI at CPD, use the earlier decision only to decide which mechanism applies. Do not use the earlier decision as the CPD.
2. Unclear CPD basis
If the basis for the CPD is unclear, carefully consider the following factors to reasonably determine the basis for the CPD:
Basis code or vocational rule was cited (if any),
Presence or absence of an RFC assessment (whether on an RFC
