Complete supplemental development of evidence to resolve insufficiencies or material
                        inconsistencies in the evidence. Supplemental development may also be necessary when
                        a reasonable effort has not been made to develop a complete medical history and all
                        available medical sources were not contacted during initial development or additional
                        sources were identified in the process of development.
                     
                     For supplemental development of evidence, see DI 22505.008.
                     
                     REMINDER: If the medical source cannot or will not provide the requested evidence, discontinue
                        development from the source.
                     
                     For information on when not to make a request for medical information from a source,
                        see DI 22505.006A3.
                     For information on when to discontinue follow-up activities because the medical source
                        cannot or will not provide the requested medical evidence, see DI 22505.035.
