You just got your military ID. Someone tells you that you have Tri Care. Now what? The website has a dozen links, the clinic asks for a referral you didn’t know you needed, and the pharmacy counter says your prescription isn’t covered. This guide walks you through the practical steps—from figuring out which plan you have to filing a claim—so you can actually use your benefits without spending hours on hold.
Step 1: Figure Out Which Tri Care Plan You Have
Tri Care isn’t one plan. It’s a family of health plans, and the rules change depending on which one you’re in. The three you’ll hear most often are Prime, Select, and For Life.
How to check your plan
- Active duty: You’re automatically enrolled in Tri Care Prime. There’s no paperwork to file, but you do need to assign a primary care manager (PCM).
- Retirees: You may have Prime (if you enroll and pay the annual fee) or Select (if you want more flexibility).
- Age 65+: You’re likely on Tri Care For Life, which works alongside Medicare.
If you’re not sure, log into the milConnect portal or call your regional contractor. The plan name is printed on your Tri Care card. For a deeper breakdown of how each plan works, see this practical guide to TRICARE coverage.
Step 2: Enroll or Update Your Information in DEERS
DEERS is the Defense Enrollment Eligibility Reporting System. It’s the database that proves you’re eligible for Tri Care. If your information is wrong or missing, your claims will be denied—even if you have a card.
Common DEERS mistakes
New babies, new spouses, and recent retirees are the usual culprits. A newborn must be registered in DEERS within 90 days to avoid a gap in coverage. A new spouse needs to be added before they can use any benefits. And if you’ve recently retired, make sure your status has been updated from active duty to retired.
I once saw a family pay $400 out of pocket for a sick visit because their newborn wasn’t registered in DEERS yet. The clinic had no way to verify coverage, so they billed the family directly. Registering the baby took 15 minutes online and would have saved them the headache.
You can update DEERS online, by phone, or at a military ID card office. Bring your marriage certificate, birth certificate, or retirement orders, depending on the change.
Step 3: Know Your Costs Before You Go
Tri Care isn’t free for everyone. Even active duty families pay copays for some services. Knowing the numbers ahead of time prevents surprises at the pharmacy or billing office.
Here’s a quick snapshot of typical costs for common plans:
- Prime (active duty): $0 for most care, including preventive visits. $0 for generic prescriptions at military pharmacies.
- Prime (retiree): $25 copay for a specialist visit. $12 for a 30-day supply of a brand-name drug at a retail network pharmacy.
- Select: You pay a deductible ($150 for an individual, $300 for a family, as of 2024) and then 20% of covered services. Preventive care is free.
- For Life: You pay nothing out-of-pocket for Medicare-covered services, as long as Medicare pays first.
Check the current TRICARE costs page for your plan year. Rates change annually, and the pharmacy copays are different for generic, brand-name, and non-formulary drugs. Also look up the catastrophic cap—the maximum you’ll pay out of pocket each year. For Select, that cap can save you from financial ruin if you have a major medical event.
Step 4: Find a Provider Who Actually Takes Tri Care
“Do you take Tri Care?” is the wrong question. A provider might say yes because they’ll file the claim for you as an out-of-network provider—and then you get a bill for the difference. The right question is: “Are you a TRICARE-authorized network provider?”
How to search for a provider
Use the online provider directory on the TRICARE website. Filter by your plan (Prime or Select), your location, and the type of specialist you need. Then call the office and confirm two things: (1) they are in the network for your specific plan, and (2) they are accepting new patients with your insurance.
One reader called a dermatologist who said “we take Tri Care.” She booked an appointment, only to find out the office was out-of-network and the visit cost her $180 instead of a $25 copay. A two-minute call to confirm network status would have saved her $155.
If you’re on Prime, you’ll also need to make sure your PCM is assigned and that the specialist accepts your PCM’s referral.
Step 5: Get Referrals and Authorizations (When Required)
This is where most people get burned. On Prime, your PCM is the gatekeeper. If you book a specialist directly without a referral, Tri Care may not pay for the visit—even if the specialist is in-network.
Prime vs. Select rules
On Prime, you need a referral for almost every specialist. The PCM will create a referral in the system, and you’ll get an authorization number. Keep that number. On Select, you don’t need a referral for most specialists, but you do need one for certain services like mental health care, surgery, and durable medical equipment.
Always check the specific rules for the service you need. For example, a routine mammogram might not need a referral, but an MRI usually does. And if you need physical therapy, a referral might cover only a set number of visits—say, 12. If you need more, your PCM has to renew it.
Step 6: Fill Prescriptions Without Overpaying
Tri Care has three pharmacy options: military pharmacies, retail network pharmacies, and home delivery. The cost difference can be significant.
For a 90-day supply of a generic maintenance medication, you might pay $10 at a military pharmacy, $24 at a retail network pharmacy, or $16 through home delivery. That’s a $14 difference per fill—enough to matter over a year.
Before you fill a new prescription, check the TRICARE formulary. If your drug isn’t on it, you may need a prior authorization or a different medication. Ask your doctor if a generic or formulary alternative is available.
Step 7: Handle Claims and Bills (It’s Usually a Coding Error)
Most network providers file claims for you. You shouldn’t have to submit paperwork. But sometimes you get a bill in the mail for something that should have been covered.
What to do if you get a bill
First, don’t pay it right away. Check your Explanation of Benefits (EOB) or the TRICARE claims portal. Look for the reason code. Often it’s a simple mistake: the provider used the wrong diagnosis code, or they billed a preventive service as diagnostic.
Call the provider’s billing office and ask them to resubmit the claim with the correct code. If that doesn’t work, call your regional contractor. They can walk you through the appeal process. You have 90 days to file an appeal for most claims.
Example: A retiree received a $300 bill for a lab test that should have been covered under Prime. The provider had accidentally billed it as a non-covered screening. One phone call to the regional contractor fixed it, and the bill was waived.
Step 8: Travel and PCS Moves: Don’t Assume You’re Covered
Tri Care Prime is great at home. It’s not designed for travel. If you’re going on vacation outside your home region, you may need to switch to Tri Care Select or get a referral for urgent care.
Overseas travel
Prime doesn’t cover routine care in most foreign countries. You can pay out of pocket and file a claim for reimbursement, but it’s a hassle. For a trip to Mexico or Europe, consider standalone travel insurance. This guide to what trip insurance really covers explains the fine print that gets claims denied.
PCS moves
When you move, you must transfer your Prime enrollment to your new region. If you’re moving overseas, you’ll switch to Tri Care Prime Overseas. Don’t wait until you arrive—start the transfer 30 days before your move. A family who PCS’d from Texas to Germany without transferring their enrollment spent two weeks paying out of pocket for routine care before their new coverage kicked in.
If You’re Over 65: How Tri Care For Life Works with Medicare
Once you turn 65, you must enroll in Medicare Part A and Part B to keep Tri Care For Life. Medicare pays first, and Tri Care pays second. You pay nothing out-of-pocket for Medicare-covered services.
You don’t need a Medicare Advantage plan. In fact, signing up for one can complicate your Tri Care For Life coverage. But if you’re comparing options—say, for a spouse who isn’t eligible for Tri Care—it helps to understand how those plans work. This explanation of how UnitedHealthcare Medicare plans work is a good starting point.
A 5-Minute Checklist Before Every Appointment
Before you walk into any clinic, run through this list:
- Is my PCM assigned and is my enrollment current?
- Do I have a referral or authorization number, if needed?
- Is the provider in-network for my specific plan?
- Have I checked the formulary for any prescriptions?
- Do I know my copay or cost-share?
That’s it. Tri Care doesn’t have to be a maze. Once you know which plan you’re on and follow the referral rules, it works like any other insurance—just with more acronyms.
