tricare select retired coverage is one of the most misunderstood benefits in military healthcare, and the confusion usually starts with a single assumption: that nothing changes when you leave active duty. In reality, the shift from active-duty TRICARE to a retired plan changes your costs, your enrollment rules, and your deadlines.
Miss those details and you can face higher copays or even gaps in coverage.
The stakes are real. TRICARE Open Season runs each fall, and outside a Qualifying Life Event, that window is often your only chance to enroll or switch plans for the coming year. Many retirees report being surprised by enrollment fees and network rules they never dealt with while serving.
This guide breaks down eligibility, costs, enrollment steps, pharmacy rules, and the mistakes that cost retirees the most. Each section gives you one concrete action to take.
What tricare select retired Coverage Actually Means for You
tricare select retired is the preferred-provider plan for military retirees, and it works differently from TRICARE Prime. With Select, you can see any TRICARE-authorized provider, but you pay less when you stay in-network.
The plan is administered regionally. In the U.S., two contractors handle claims: Humana Military in the East Region and TriWest Healthcare Alliance in the West. That split matters because your customer service contact, network, and referral rules depend on your ZIP code.
Key features of the retired Select plan:
- No referrals required for most specialty care, unlike Prime
- Annual deductible and cost shares apply, which Prime enrollees often avoid
- Enrollment is generally required to maintain coverage, not automatic
- Network vs. non-network status directly changes what you pay
A common scenario: a retiree moves from Texas to Georgia and assumes the same provider network applies. Because the region changed, the contractor and in-network list changed too. Checking your region before any move avoids surprise bills.
The official TRICARE site publishes current regional contractor details and plan comparisons. How to apply this: log into your milConnect account today and confirm which region and contractor are listed for your address.
The Real Costs of tricare select retired in 2025
Retired Select costs are driven by three numbers: your group (retirees pay Group A or B rates based on when you entered service), your deductible, and your cost shares.

Group A covers sponsors who entered service before January 1, 2018. Group B covers those who entered on or after that date, and Group B generally carries higher enrollment fees. Deductibles are per person and per family, and they reset each calendar year.
| Cost element | What it tells you | Action to take |
|---|---|---|
| Group A vs. B | Your fee tier | Verify your group in milConnect |
| Annual deductible | Amount before cost shares begin | Budget for it in January |
| Network copay | Your share for in-network care | Stay in-network when possible |
| Non-network cost share | Higher share plus possible balance billing | Confirm network status first |
| Catastrophic cap | Yearly out-of-pocket maximum | Track spending toward the cap |
| Pharmacy tier | Cost by drug category | Check each drug's tier |
The catastrophic cap is the detail retirees overlook most. Once your out-of-pocket costs hit the annual cap, TRICARE generally covers covered services at 100% for the rest of the year.
Exact dollar figures change annually. TRICARE publishes updated rates each fall, so confirm current numbers on the official site rather than relying on a friend's older figures.
How to apply this: pull last year's Explanation of Benefits and total your actual out-of-pocket spend against the cap.
How to Enroll or Change Your tricare select retired Plan
Enrollment in tricare select retired is not automatic for most retirees. You either enroll during Open Season or qualify through a Qualifying Life Event.
The main enrollment paths:
- TRICARE Open Season — typically runs from the second Monday in November through the second Monday in December, with coverage starting January 1.
- Qualifying Life Event (QLE) — moves, marriage, divorce, birth, retirement, or loss of other coverage open a 90-day window.
- Medicare transition — at age 65, most retirees must enroll in Medicare Part B to keep TRICARE, and TRICARE For Life becomes the secondary payer.
A frequent mistake: a retiring service member waits until after separation to think about health coverage. The retirement date itself is a QLE, so you have a 90-day window to enroll — but you must act inside it.
TRICARE's own guidance is explicit about this timing. The TRICARE eligibility page explains that retiring from active duty is a Qualifying Life Event and that you must enroll within the window to avoid a coverage gap.
How to apply this: mark your retirement date and the Open Season dates on your calendar now, then set a reminder 30 days before each.
Pharmacy and Prescription Rules Under tricare select retired
Prescription costs are where tricare select retired enrollees often save or lose the most money. The plan uses a tiered pharmacy structure, and where you fill a prescription matters as much as what it is.

The basics:
- Military pharmacies typically have the lowest cost for covered drugs
- TRICARE Pharmacy Home Delivery (mail order) is generally next cheapest for maintenance medications
- Network retail pharmacies cost more than home delivery
- Non-network pharmacies carry the highest share
Retirees on multiple maintenance medications often shift them to home delivery and report meaningful annual savings. The trade-off is planning ahead, since delivery takes time.
One authority worth citing directly: the TRICARE Pharmacy Program page states that home delivery is designed for maintenance medications and typically offers lower costs than retail. Express Scripts administers the pharmacy benefit, so that is your contact for formulary questions.
A common scenario: a retiree fills a 30-day supply at a retail pharmacy for a blood-pressure drug, unaware the same drug is far cheaper through home delivery. Moving it takes one phone call or a portal login.
How to apply this: list every prescription you take, check each drug's tier and cost at home delivery versus retail, and move maintenance drugs to mail order.
5 Mistakes Retirees Make With tricare select retired
Most costly problems with tricare select retired trace back to a small set of avoidable errors. Knowing them in advance saves both money and stress.
The five mistakes to avoid:
- Missing the Open Season deadline — outside a QLE, you may wait a full year to enroll or change plans
- Skipping Medicare Part B at 65 — failing to enroll can end your TRICARE coverage entirely
- Using non-network providers without checking — balance billing and higher cost shares follow
- Ignoring the catastrophic cap — not tracking spend means missing when full coverage kicks in
- Assuming automatic enrollment after retirement — Select generally requires you to enroll actively
A QLE window is narrow. TRICARE generally gives you 90 days from the event to make a change, and missing it usually means waiting for Open Season.
There is also a documentation angle. Keeping copies of enrollment confirmations, QLE paperwork, and Medicare cards prevents disputes later. Claims systems occasionally misplace records, and your copy resolves it fastest.
How to apply this: create a folder — physical or digital — holding your enrollment confirmation, Medicare card, and current plan details, and review it each Open Season.

Frequently Asked Questions About tricare select retired
What happens to my tricare select retired coverage when I turn 65?
At 65, you generally must enroll in Medicare Part B to keep TRICARE. Once enrolled, TRICARE For Life becomes your secondary payer and coordinates with Medicare. If you or your spouse delayed Part B enrollment, contact your regional contractor promptly, because gaps can create coverage interruptions.
Verify your Part B status before your birthday month to keep your tricare select retired transition smooth.
Can I add a family member to my tricare select retired plan mid-year?
Yes, if you have a Qualifying Life Event such as marriage, birth, or adoption. You generally get 90 days from the event to add a dependent. Outside a QLE, changes wait for Open Season. Documentation matters — keep the marriage certificate or birth record ready. This is one of the most common tricare select retired questions from new retirees.
Does tricare select retired work if I live overseas?
Generally, no. TRICARE Select is designed for the U.S. and U.S. territories. Overseas retirees typically use TRICARE Overseas Program coverage through International SOS. If you relocate abroad, contact your regional contractor before you move to arrange the transition. Planning ahead keeps your tricare select retired coverage from lapsing during an international move.
How does tricare select retired coordinate with employer health insurance?
If you have employer coverage, TRICARE generally pays after your employer plan. You must disclose other coverage when enrolling. Some retirees choose to rely on employer insurance and suspend TRICARE, then reinstate later under the rules. Confirm coordination order with your contractor before assuming which plan pays first under tricare select retired.
What if my tricare select retired claim is denied?
Start by requesting the Explanation of Benefits and confirming the reason — network status, missing referral, or coding error are common. You can file an appeal within the deadline stated on the denial notice. Contact your regional contractor's beneficiary counseling office for help. Most tricare select retired denials are resolved with documentation, so keep your records organized.
Your Next Steps for tricare select retired Coverage
