When is a beneficiary considered to be in Group B?

A beneficiary is considered to be in Group B if their sponsor enlisted or was commissioned on or after January 1, 2018. This distinction is particularly important for understanding eligibility and benefits under the TRICARE program. Group B was established as a result of changes in benefits for new entrants into military service, reflecting the updates to the service-member's compensation and health care options implemented from that date onward.

The eligibility for Group B is linked to the service dates of the sponsor, which means that new entry dates significantly influence the classification and benefits available to beneficiaries. This classification helps ensure that transition rules and healthcare policies are appropriately aligned with the service timeframes of those newly entering the military. Understanding this aspect can help beneficiaries identify their specific coverage options and any changes to their healthcare plans throughout their sponsor's service.
