Each TRICARE Manual posted on the website incorporates all published changes. Although changes are published, they are not implemented by the contractors until they receive direction to do so by the Contracting Officer. The TRICARE Reimbursement Manual (TRM) is incorporated by reference in the Managed Care Support Services (MCSS) contracts and is the principal vehicle for operating guidelines and instructions. The TRM provides a mechanism for keeping the contracts current by clarifying or modifying existing contractual requirements, adding new specifications/requirements and deleting obsolete information. The TRM, in conjunction with the February 2008 TRICARE Policy Manual (TPM), provides guidance, policy interpretation, and decisions implementing TRICARE, including those policies and procedures applicable to the Civilian Health and Medical Program of the Uniformed Services (CHAMPUS). The TRM contains operational policy necessary to implement Title 32 to the Code of Federal Regulations Part 199 (32 CFR 199). This manual augments the 32 CFR 199 and must be used in conjunction for complete policy information.
