Does TRICARE for Life Cover Spouses? Eligibility, Costs, and Claims

Yes. TRICARE for Life does cover spouses of military retirees, and it covers them in their own right rather than as an add-on to the retiree’s policy. To get it, an eligible spouse must be registered in the Defense Enrollment Eligibility Reporting System (DEERS) and enrolled in both Medicare Part A and Medicare Part B. Once both parts are active, TRICARE for Life begins automatically, with no enrollment form and no premium of its own. The ongoing cost is the Medicare Part B premium, which is $202.90 per month at the standard rate in 2026.¹

Which Spouses Are Eligible

Federal law defines a military dependent to include the current spouse of a service member or retiree, an unremarried widow or widower, and certain former spouses.² Anyone within that definition who is otherwise eligible for TRICARE can receive TRICARE for Life once they become Medicare-eligible.³

Current Spouses

If you are married to a retired service member, you qualify as an eligible dependent. Your coverage is independent of your spouse’s, so each of you qualifies based on your own age and Medicare status. If you are younger than the retiree, you stay on your current TRICARE plan, such as TRICARE Prime or TRICARE Select, until you turn 65 or otherwise become Medicare-eligible.⁴ Your existing plan doesn’t change just because the retiree moved to TRICARE for Life. The retiree’s transition does count as a qualifying life event, giving you a 90-day window to switch plans if you want.

Surviving Spouses

If your military spouse has died, you keep TRICARE eligibility as long as you do not remarry.⁵ At 65, once you have Medicare Part A and Part B, your coverage transitions to TRICARE for Life automatically. Remarriage ends TRICARE eligibility, regardless of your age when it happens.

Former Spouses

Divorced spouses of military retirees can keep TRICARE, including eventual TRICARE for Life, if they meet one of two overlap tests:⁶

The 20/20/20 rule: the sponsor served at least 20 years of creditable service, the marriage lasted at least 20 years, and all 20 marriage years overlapped the 20 service years. This gives you the same TRICARE options as a retired family member, including TRICARE for Life, for as long as you remain unmarried.
The 20/20/15 rule: same service and marriage requirements, but only 15 of the marriage years overlapped the service years. For divorces finalized on or after September 29, 1988, coverage lasts only one year from the date of divorce.

The Medicare Part A and Part B Requirement

TRICARE for Life is available only to people who carry both Medicare Part A and Medicare Part B.⁷ There is no separate TRICARE for Life form and no enrollment fee. Coverage starts the first day you hold both parts. That means the whole eligibility question, for spouses, comes down to Medicare enrollment.

Enrolling on Time

Your Initial Enrollment Period for Medicare runs seven months: the three months before the month you turn 65, your birthday month, and the three months after.⁸ Signing up during the first three months means Medicare (and therefore TRICARE for Life) starts the month you turn 65, with no gap.

The Late Enrollment Penalty

Miss your Initial Enrollment Period without qualifying for a Special Enrollment Period and you’ll pay a lifetime penalty on Part B. The penalty adds 10 percent to your monthly premium for each full 12-month period you could have been enrolled but weren’t.⁹ A two-year delay means a permanent 20 percent surcharge. You would also have no TRICARE for Life during the gap.

If You Are Still Working

If you or your working spouse have employer-sponsored health coverage at 65, you can delay Part B without the late penalty. Once the job or the employer coverage ends, whichever comes first, an eight-month Special Enrollment Period opens for Part B.¹⁰ During any delay you will not have TRICARE for Life, because you don’t yet have Part B, and TRICARE will not act as a secondary payer to your employer plan in the meantime.¹¹

Before Age 65 on Disability

Spouses receiving Social Security Disability Insurance become Medicare-eligible after a 24-month waiting period.¹² Once that waiting period ends and both Part A and Part B are active, TRICARE for Life begins automatically. You don’t have to wait for 65.

If You Drop Part B

Drop Part B or stop paying the premium and you lose TRICARE for Life immediately.¹¹ You would generally have to wait for the Medicare General Enrollment Period (January 1 through March 31), with coverage restarting July 1, and a late enrollment penalty would likely apply going forward. You’d have no TRICARE coverage during that gap.

What a Spouse Actually Pays

TRICARE for Life itself has no premium and no enrollment fee.⁷ The costs you carry are on the Medicare side.

Part B Premium in 2026

The standard monthly Part B premium is $202.90 in 2026. Higher-income beneficiaries pay more through the Income-Related Monthly Adjustment Amount (IRMAA). For individual filers, the 2026 brackets are:¹

$109,000 or less: $202.90
$109,001 to $137,000: $284.10
$137,001 to $171,000: $405.80
$171,001 to $205,000: $527.50
$205,001 to $499,999: $649.20
$500,000 or more: $689.90

For married couples filing jointly, the income brackets are roughly doubled. The standard rate applies at joint income of $218,000 or less.

Part A Premium If You Don’t Qualify Free

Most people get Part A without a premium based on their own or a spouse’s 40 quarters of work (about 10 years). A military spouse who did not work outside the home may not meet that threshold. Without premium-free Part A, the cost can run up to $565 per month in 2026.¹³ Check your standing with the Social Security Administration well before turning 65.

How Claims Work

TRICARE for Life pays last, after Medicare and any other health insurance.¹⁴ Medicare processes the claim first, and the balance transfers automatically to the TRICARE claims processor. You don’t file anything separately. For services both programs cover, TRICARE for Life picks up the remaining Part B deductible ($283 in 2026)¹ and Medicare’s 20 percent coinsurance, often leaving nothing owed at the point of care.

If a service is covered by TRICARE but not Medicare, TRICARE pays first. If Medicare covers a service but TRICARE doesn’t, you are responsible for any remaining coinsurance.

Overseas

Medicare doesn’t pay for care outside the United States and its territories. Overseas, TRICARE for Life becomes the primary payer instead of the secondary payer, and you owe TRICARE’s annual deductible and cost-shares.¹⁵ You still have to keep Part B enrolled to keep TRICARE eligibility, even if Medicare pays nothing for care in the country where you live.

Prescriptions

Pharmacy benefits come through the TRICARE pharmacy program, which covers the same medications as other TRICARE plans. Medicare Part D is not required, and adding it generally means paying a premium for overlapping coverage.¹⁶ You can fill prescriptions at military pharmacies at no cost, through TRICARE mail order, or at retail pharmacies with applicable copayments.

Gaps to Plan Around

TRICARE for Life is broad, but it does not cover everything a spouse may need later in life.

Long-Term and Custodial Care

TRICARE does not cover long-term care, which includes help with daily activities such as eating, dressing, bathing, and moving around.¹⁷ Extended nursing home stays and in-home personal assistance fall on you: out of pocket, private long-term care insurance, or eventual Medicaid.

Dental and Vision

Routine dental and vision care are not part of TRICARE for Life. Retirees and their eligible family members can buy separate coverage through the Federal Employees Dental and Vision Insurance Program (FEDVIP), which opens annually during the Federal Benefits Open Season in November and December.¹⁸

Keeping DEERS Current

TRICARE verifies eligibility through DEERS. If your record is missing or outdated, claims can be denied, because the regulations allow ineligibility to be presumed when the system lacks proper documentation.¹⁹ As a spouse, you’re responsible for making sure your record is accurate and that status changes (address, marriage, divorce, death of the sponsor) are reported promptly.

To update or verify your record, visit a Real-Time Automated Personnel Identification System (RAPIDS) site at a military installation with legal documentation such as a marriage certificate, divorce decree, or death certificate.²⁰ You can also check your status through the milConnect portal to confirm your Medicare eligibility flag before your 65th birthday.

Transitioning to TRICARE for Life at 65

Start several months out. The key steps:

Verify your DEERS record three to six months ahead, and confirm your information is current.
Enroll in Medicare Part A and Part B during the first three months of your Initial Enrollment Period so coverage begins the month you turn 65.⁸
Get a new permanent Uniformed Services ID card at any ID card office after turning 65.²¹
Confirm coverage through milConnect once Part A and Part B are active. TRICARE for Life begins automatically.
