Not sure if you’ve seen this page, but has some useful info and POC’s. Looks like MRR needs to be recommended by BUMED. I’m not sure what category you fall into below, but might help point you in the right direction.
PERS-951: Medical Hold (MEDHOLD)
The MEDHOLD program authorizes reservists to be retained on active duty to receive medical treatment for service-connected injury, illness or disease that is incurred or aggravated while on continuous active duty orders of more than 30 days and results in a potentially unfitting condition, as determined by a military physician. If authorized, member will be retained on active duty, with member’s consent, until found fit for duty or until final disposition is determined by the Physical Evaluation Board (PEB). Elective medical/dental treatment is not authorized. Reference SECNAVINST 1770.5.
PERS-953: Medical Retention Review (MRR)
An MRR package is submitted to BUMED for reservists who develop, or have a material change in, a potentially disqualifying medical condition that is not expected to resolve within 180 days and is likely to prevent member from safely/effectively fulfilling the responsibilities of their grade/designator/rating or interfere with mobilization. PERS-953 adjudicates MRR packages based on BUMED recommendations, assigns Physical Risk Classification (PRC) codes and prepare messages for release. Reference MILPERSMAN 6110-020 and RESPERSMAN 6000-010.
PERS 954: Temporary Disability Retirement List (TDRL) & Permanent Disability Retired List (PDRL)
Processes results of the Physical Evaluation Board's (PEB) Notification of Decision, and produces orders to discharge members from Active or Reserve Component to either the Temporary (TDRL) or Permanent (PDRL) Disability Retirement List for eventual processing by local command Personnel Support Detachments (PSD) or Navy Operational Support Command (NOSC). TDRL is a program designed to enable all eligible members with a rated disability the opportunity to receive retirement benefits, which include medical coverage for members and dependents, and a monthly stipend until medical conditions can become stabilized or corrected. TDRL is also responsible for the processing of all orders directing disability rated service members to undergo Periodic Physical Medical Examinations, and their resulting travel reimbursements. PDRL is a program designed to provide permanent disability benefits to members of the military with service-connected disabilities.
Medical Department Representatives (MDRs) can obtain the forms and documents required for LOD-HC and MRR requests from Medical Readiness and Reporting System (MRRS). Commands requiring MEDHOLD request procedures should contact PERS-951 at the e-mail below. LOD-HC related requests must be submitted by the NOSC/Squadron via RCC/Wing to the appropriate LOD-HC inbox listed below. MRR requests must be submitted in WEBWAVE.
