MINE or MINE-equivalent impairments are considered permanent. Therefore, extensive
            current medical development is not needed. However, the disability determination services
            (DDS) must contact a current medical source when possible. The DDS may obtain evidence
            quickly for expedited processing by telephone contact with the medical source, or
            the source’s representative (e.g., nurse, secretary, etc.). If no medical source is
            available, see DI 28040.125.
         
         This section contains information specific to continuing disability reviews (CDR)
            and MINE or MINE-equivalent impairments. However, general information on obtaining
            medical evidence by telephone is located in DI 22505.030.
