TRICARE planning
Confirm eligibility, plan rules, and provider status before care.
Use this guide to organize the TRICARE question before you schedule care: who is covered, which plan path applies, which region or contractor handles the case, and what must be verified before an appointment. VA Companion can help build a provider shortlist and call script; official eligibility, enrollment, referrals, authorizations, and final network status still come from TRICARE, DEERS, milConnect, or the regional contractor.
TRICARE is not a single provider list. Eligibility starts with the sponsor's uniformed service and DEERS record, then plan options depend on beneficiary category, location, Medicare status, and qualifying life events.

Who TRICARE is for
TRICARE serves uniformed service sponsors and eligible family members. Common categories include active duty families, Guard and Reserve families, retired service members and families, survivors, children, certain former spouses, Medicare-eligible beneficiaries, and other special groups.
Active duty families
Active duty service members generally follow a Prime option tied to duty station and military care access. Family members may use Prime options, Select, US Family Health Plan in certain areas, overseas options, or TRICARE Young Adult when adult-child rules apply.
Guard and Reserve
Guard and Reserve coverage can change when the sponsor is inactive, activated for more than 30 days, deactivated, in line-of-duty care, retired, or in the Retired Reserve. Verify the current sponsor status before assuming coverage or scheduling care.
Retired and Medicare-eligible
Retired service members and families may have Prime, Select, US Family Health Plan, Select Overseas, or TRICARE For Life options. If a beneficiary is eligible for both TRICARE and Medicare Part A, Medicare Part B is usually required to keep TRICARE coverage.
Provider types
Care can come through military hospitals or clinics, civilian network providers, or TRICARE-authorized non-network providers. Network status, authorized status, and plan rules affect costs, claims, and whether the provider can bill TRICARE.
Finding care
TRICARE provider directories can differ by plan, region, location, and provider type. Use VA Companion to build a shortlist, then confirm the provider through official TRICARE tools or the provider billing office before care.
Pharmacy and prescriptions
Prescription rules can depend on military pharmacy access, retail pharmacy, home delivery, formulary status, prior authorization, and whether Medicare or another plan is involved. Confirm pharmacy benefits before assuming the office visit and medication fill will process the same way.
Referrals and authorizations
Prime-style plans commonly require a primary care manager referral for specialty care, and some services need prior authorization. Ask who requests it, which NPI and location it must name, and whether you need the number before the appointment.
