The attached file is an APDA memorandum for PEB Presidents on what happens when the MEB and the VA disagree with a diagnosis.
Note that per ANNEX O (MEB Phase Implementation Guidance) to OPORD 12-31 (MEDCOM IMPLEMENTATION of the INTEGRATED DISABILITY EVALUATION SYSTEM),
"(8) [CHANGE] No Diagnostic Variance Memorandums (DVMs) will be written. The MEB provider discusses each diagnosis from the VA C&P examination in the NARSUM and includes each diagnosis on the DA 3947. Diagnoses from the VA C&P examination without supporting medical documentation will first be clarified from the VA C&P examiners (as per paragraph 6.d.(5)). The MEB provider indicates "no medical basis" for VA C&P examination diagnoses for which the VA provided no medical basis (and for which none appears in the record). No additional clinical diagnostic re-evaluation is conducted by the MEB provider. The diagnosis will still be included in the NARSUM and included on the DA 3947 with the statement "no medical basis.""
