TRICARE; constructive eligibility for TRICARE benefits of certain persons otherwise ineligible under retroactive determination of entitlement to Medicare Part A hospital insurance benefits. Final rule

The Department is publishing this final rule to implement section 706 of the National Defense Authorization Act (NDAA) for Fiscal Year 2010, Public Law 111-84. Specifically, section 706 exempts TRICARE beneficiaries under the age of 65 who become disabled from the requirement to enroll in Medicare Part B for the retroactive months of entitlement to Medicare Part A in order to maintain TRICARE coverage. This statutory amendment and final rule only impact eligibility for the period in which the beneficiary's disability determination is pending before the Social Security Administration. Eligible beneficiaries are still required to enroll in Medicare Part B in order to maintain their TRICARE coverage for future months, but are considered to have coverage under the TRICARE program for the retroactive months of their entitlement to Medicare Part A. This final rule also amends the eligibility section of the TRICARE regulation to more clearly address reinstatement of TRICARE eligibility following a gap in coverage due to lack of enrollment in Medicare Part B.
