Most active-duty families should be on TRICARE Prime. It costs them nothing, and for a family with kids near a base, it’s hard to beat free. That’s the short answer, and for a lot of you it’s the only answer you need.
But “most” is not “all.” If you live an hour from the nearest network provider, if you want to see specialists without chasing referrals, or if you’re about to PCS overseas, Prime can quietly become the wrong call. The plans aren’t priced the same, they don’t work the same, and switching is locked to a yearly window that, for 2026, has already closed.
Here’s how to pick the right plan for your actual situation, with the real 2026 numbers and the decision rules nobody lays out in one place.
TRICARE in 60 seconds
TRICARE is the military health program. For the people choosing a plan, it comes down to a few options:
- Prime is managed care. You get a Primary Care Manager (PCM) who handles your care and refers you out for specialists. Cheapest by far, least flexible.
- Select is fee-for-service. You see any TRICARE-authorized provider without referrals, but you pay deductibles and cost-shares.
- Overseas versions of both exist for families stationed abroad.
- TRICARE For Life is the Medicare wraparound for retirees who have Medicare Part A and B.
- TRICARE Reserve Select is the premium-based plan for Guard and Reserve.
Two terms you need before the numbers make sense. Group A means your sponsor first enlisted or was appointed before January 1, 2018. Group B means on or after that date. Your costs depend on which group you’re in, so check your sponsor’s start date first.
The three plans active-duty families actually choose between
Prime, Select, and (if you’re stationed abroad) the overseas version. The retiree and Reserve plans are separate tracks covered further down.
Here are the verified 2026 costs for active-duty family members.
| Prime (ADFM) | Select Group A (ADFM) | Select Group B (ADFM) | |
|---|---|---|---|
| Annual enrollment fee | $0 | $0 | $0 |
| Annual deductible (E-1–E-4) | $0 | $50 indiv / $100 family | $66 indiv / $132 family |
| Annual deductible (E-5+) | $0 | $150 indiv / $300 family | $198 indiv / $397 family |
| Primary care visit | $0* | $28 | $19 |
| Specialty visit | $0* | $39 | $33 |
| Urgent care | $0* | $28 | $26 |
| Emergency room | $0* | $103 | $52 |
| Referrals required? | Yes | No | No |
| Catastrophic cap (family) | $1,000 (A) / $1,324 (B) | $1,000 | $1,324 |
*Prime care is $0 for active-duty family members when you follow the rules — using your PCM and getting referrals. Self-refer to an outside provider without a referral and you drop into the Point-of-Service option: a $300 individual / $600 family deductible, then you pay 50% of the cost, and none of it counts toward your catastrophic cap.
The pattern: Prime is free but routes you through a PCM and referrals. Select costs real money per visit but lets you go straight to any authorized provider. Note also that Select’s enrollment fee for active-duty families is $0 in 2026 — the cost is in the per-visit shares and the deductible, not an upfront fee.
Decision: active-duty family in CONUS with kids
Default to Prime. For a family that lives reasonably close to a military treatment facility or a dense network area, free routine care, free specialist visits (with referrals), and a $1,000–$1,324 catastrophic cap is the best deal in American health care. Kids need a lot of routine visits, and at $0 each, Prime wins.
When Prime doesn’t win, even in CONUS:
- You live far from the network. Prime assigns you a PCM, and that PCM may be inconveniently far. If the nearest network provider is a long drive and you’d rather use a local doctor who isn’t in-network, Select’s freedom can be worth the cost-shares.
- You hate referrals. If your family sees specialists often and the referral process drives you up a wall, Select buys you direct access. You’re paying $33–$39 a specialty visit (Group B/A) to skip the PCM gatekeeping.
- You have a specific civilian doctor you won’t give up. If that doctor takes TRICARE but isn’t a Prime network PCM, Select keeps you with them.
For most CONUS families with young kids, none of those outweigh free. Start with Prime and only move if one of the above genuinely applies to you.
Decision: PCS’ing overseas or to a remote duty station
Your plan changes when you leave CONUS, and the deciding factor is command sponsorship.
- Command-sponsored family overseas: TRICARE Prime Overseas works like stateside Prime. Assigned PCM, referrals, $0 cost-shares for family members. This is the standard setup for accompanied tours.
- Not command-sponsored: You enroll in TRICARE Select Overseas, the fee-for-service option, and you can see any TRICARE-authorized provider with the usual cost-shares.
- Remote overseas locations have their own version, TRICARE Prime Remote Overseas, for designated remote areas.
The thing to get right before you move: confirm whether your family is command-sponsored, because it determines which overseas plan you’re even eligible for. Sort that out before the PCS, not after you land and need care.
Decision: Guard and Reserve
If you’re a drilling Guard or Reserve member not on active-duty orders, your option is TRICARE Reserve Select (TRS), a premium-based plan you buy. For 2026 the premium is $57.88 a month for member-only coverage and $286.66 a month for member-and-family. Its deductibles and cost-shares mirror Select Group B (primary care $19, specialty $33, a $1,324 family catastrophic cap).
At under $290 a month for a whole family with a hard cap on catastrophic costs, TRS is one of the cheapest family health plans available anywhere. If you’re Guard or Reserve without employer coverage you actually like, run the numbers on TRS before you buy anything on the civilian market.
Decision: retirees and TRICARE For Life
Once you’re a retiree, the picture shifts. Before Medicare eligibility you choose between Prime and Select as a retiree (with real enrollment fees now — Select runs $186.96 individual / $375 family per year for Group A in 2026, more for Group B). Once you have Medicare Part A and Part B, TRICARE For Life becomes your coverage. It’s a wraparound: Medicare pays first, TRICARE picks up much of the rest, and there’s no separate TRICARE enrollment fee. The one thing that trips retirees up is failing to enroll in Medicare Part B, which TFL requires.
Open enrollment: when you can change, when you can’t
This is the part that surprises people. You can’t switch TRICARE plans whenever you feel like it.
TRICARE Open Season is the annual window to enroll or change plans. For 2026 coverage, that window ran November 10 to December 9, 2025, and it’s closed. The next Open Season, around November 2026, sets your 2027 coverage. Open Season runs each fall for the following year, roughly from the Monday of the second full week of November through the Monday of the second full week of December.
Open Season doesn’t apply to everyone. Active-duty members can’t change (your coverage is set). TRICARE For Life needs no action. And the premium-based plans (TRS, Retired Reserve, Young Adult) can be bought any time.
Outside Open Season, you need a Qualifying Life Event (QLE) to change. A QLE opens a 90-day window to make eligible changes, and coverage tied to it starts on the date of the event. QLEs include marriage, divorce, a birth or adoption, a PCS move, your sponsor retiring or separating or activating, losing other coverage, or becoming Medicare-eligible. One family member’s QLE lets every eligible member change. If you’re reading this mid-year and want to switch, a QLE is your only door until next Open Season.
The mistakes that cost families money
- Not checking PCM network before a PCS. People stay on Prime through a move and discover their new PCM is 45 minutes away. Verify network coverage at your next duty station before you decide.
- Self-referring on Prime. Skipping the referral and seeing an outside provider drops you into Point-of-Service: a separate deductible, 50% cost-shares, and none of it counting toward your catastrophic cap. If you’re on Prime, use the PCM and get the referral.
- Missing the Open Season window. Forget it, and you’re locked into your current plan until the next fall unless you have a QLE.
- Retirees missing Medicare Part B. TRICARE For Life requires both Part A and Part B. Skip Part B and your wraparound coverage doesn’t work.
- Assuming Select’s fee is the whole cost. Active-duty families pay $0 to enroll in Select for 2026, but the deductibles and per-visit cost-shares add up. Run your family’s actual visit count before assuming Select is “almost free.”
The bottom line
If you’re an active-duty family near a base, start with Prime. It’s free, and for routine family care nothing beats it. Move to Select only if distance, referrals, or a specific provider you won’t leave make the per-visit costs worth it. Overseas, your plan is decided by command sponsorship, so confirm that before you move. Guard and Reserve should price out TRICARE Reserve Select against any civilian option. Retirees should make sure they’re enrolled in Medicare Part B before relying on TRICARE For Life. And whatever you choose, remember the only times you can change are Open Season each fall or within 90 days of a Qualifying Life Event.
