DHCAPE is responsible for the Functional Specifications of the MHS Data Repository (MDR) and MHS Mart (M2). For each functional
specification there may be two accessible versions at any one time. The Current System version documents the specific file as it currently exists. If
present, the Future System version documents the file as it will be once proposed changes are implemented. Once those changes have been
implemented, the Future System version will be reclassified as the Current System version.
Each specification is assigned a status that reflects its level of permanence. Preliminary is a draft designation that identifies a working document to
which further changes are anticipated. Final is also a draft designation that indicates that the file is not likely to change.
The files available here are the most current versions of a document. The repository is updated as new versions are released. If you have any
questions or need access to an older version of a specification, please email the functional specifications manager at

“On October 1, 2013, the Department of Defense established the Defense Health Agency (DHA) to manage the activities of the Military Health System. These activities include those previously managed by TRICARE Management Activity (TMA), which was disestablished on the same date. During the next several months, all TMA websites will change to reflect the new DHA. We appreciate your patience during this transition."
