TRICARE For Life is widely considered one of the best insurance options available to military retirees. It functions as a Medicare supplement with no enrollment fee and no monthly premium beyond what you already pay for Medicare Part B, which is $202.90 per month in 2026. For most beneficiaries, TFL picks up nearly all the costs that Medicare doesn’t cover, often leaving you with zero out-of-pocket expenses for doctor visits and hospital stays.
How TFL Actually Works
TRICARE For Life is a wraparound plan, meaning it coordinates directly with Medicare to cover your medical bills. When you see a doctor or go to the hospital, Medicare pays first as the primary insurer. TFL then steps in as the secondary payer and covers most or all of whatever Medicare leaves behind: deductibles, copays, and coinsurance. In practice, this two-layer system means many TFL beneficiaries pay nothing out of pocket for Medicare-covered services.
Enrollment is automatic. The moment you have both Medicare Part A and Part B in effect, TFL kicks in. There’s no application, no waiting period, and no annual enrollment window to worry about. The only requirement is that you maintain both parts of Medicare and remain TRICARE-eligible, which generally means you’re a military retiree, a retiree’s spouse, or a qualifying dependent.
What It Costs Compared to Medigap Plans
The most striking advantage of TFL is its price. Private Medicare supplement plans (often called Medigap) charge monthly premiums that typically range from $100 to $300 or more, depending on your age, location, and the plan you choose. TFL charges nothing on top of the Medicare Part B premium you’re already required to pay. That savings alone can add up to thousands of dollars a year.
TFL also has no annual deductible of its own for Medicare-covered services, and there’s no network restriction for civilian providers. You can see any doctor who accepts Medicare. About 90% of primary care and specialty care providers accept TRICARE patients, though access to mental health providers is tighter, with only about 47% accepting new TRICARE patients.
Prescription Drug Coverage
One area where TFL stands apart from most Medigap plans is pharmacy benefits. Medigap does not cover prescription drugs at all, so most Medicare beneficiaries need a separate Part D drug plan, which comes with its own premium and formulary restrictions. TFL includes pharmacy coverage through the TRICARE pharmacy program, eliminating the need for Part D entirely.
Copays through TFL’s pharmacy benefit are relatively low. For a 90-day supply through home delivery, you’ll pay $14 for a generic drug, $44 for a brand-name formulary drug, and $85 for a non-formulary drug. At a retail pharmacy, a 30-day supply costs $16 for generics, $48 for brand-name, and $85 for non-formulary medications. If you fill prescriptions at a military treatment facility pharmacy, the cost is $0.
Overseas Coverage
TFL provides a benefit that almost no civilian Medicare supplement offers: coverage outside the United States. Medicare itself does not pay for care in other countries, but if you’re a TFL beneficiary living or traveling overseas, TRICARE becomes your primary payer. You’ll be responsible for TRICARE’s annual deductible and cost-shares, but you still have meaningful insurance coverage abroad. International SOS serves as the overseas contractor and helps with claims, provider searches, and authorizations.
There’s an important catch: even though Medicare doesn’t cover anything overseas, you must keep paying your Part B premium to stay eligible for TRICARE. Dropping Part B, even while living abroad, means losing TFL entirely.
What TFL Does Not Cover
TFL is generous, but it has real gaps. Dental and vision care are not included. If you want those benefits, you’ll need to enroll separately through the Federal Employees Dental and Vision Insurance Program (FEDVIP). Military retirees and their families are eligible for FEDVIP dental coverage, and those enrolled in a TRICARE health plan can also sign up for FEDVIP vision coverage. These plans carry their own premiums.
Long-term custodial care, the kind provided in nursing homes for people who need help with daily activities like bathing or eating, is not covered. TFL does cover skilled nursing facility care, which involves a higher level of medical treatment including nursing, rehabilitation, physical therapy, and medications. There’s no day limit on skilled nursing as long as the care remains medically necessary, though TFL requires pre-authorization starting on day 101. To qualify, you generally need a hospital stay of at least three consecutive days before transferring to the facility.
Beneficiary Satisfaction
Government surveys paint a generally positive picture. About 80% of TRICARE beneficiaries rate their health care positively, and 68% give positive ratings to their health plan overall. The most common frustration is finding specialists who accept TRICARE. In one survey period, the percentage of beneficiaries reporting difficulty accessing specialty providers rose from 18% to 24%. Mental health access is a particular pain point given the lower provider acceptance rate.
These satisfaction numbers reflect TRICARE broadly, not TFL specifically, but TFL beneficiaries have the added flexibility of seeing any Medicare-accepting provider. That larger provider pool helps offset some of the access issues that affect other TRICARE plans.
The Bottom Line on Value
For the population eligible to use it, TFL is hard to beat. It offers Medigap-level coverage with no additional premium, includes prescription drug benefits that eliminate the need for a Part D plan, and provides overseas coverage that civilian supplements simply don’t match. The main limitations are the absence of dental and vision coverage and the lack of long-term custodial care, both of which are gaps shared by virtually every Medicare supplement on the market. If you’re eligible for TFL, it’s one of the strongest health insurance benefits available to any retiree population in the United States.
