NPRC-MPR also stores medical treatment records of retirees from all branches and services, as well as records for dependents and other persons treated at naval medical facilities. Information from these records is made available upon written request (with dated signature). Requests must contain sufficient information to locate the record such as: complete name as it appears on the service records, service number or social security number, branch of service, and dates of service.
