Yes. TRICARE For Life covers rehab, and for most services it does it very well, because it wraps around Medicare. When a rehab service is covered by both Medicare and TRICARE, Medicare pays first, TRICARE For Life pays the rest, and retirees often owe nothing. The one gap worth knowing is residential substance use rehab, which Medicare generally does not cover, so TRICARE For Life pays under TRICARE rules and you owe a cost-share. Here is how it works, level by level.
Retirees who age into Medicare at 65 often worry that their addiction or mental health coverage narrows. For rehab, the opposite is usually true. The combination of Medicare and TRICARE For Life is one of the more generous setups out there.
The trick is understanding who pays first, because that single mechanic decides whether a given level of care costs you nothing or a modest cost-share.

Does TRICARE For Life cover rehab?
Yes. TRICARE For Life is Medicare-wraparound coverage for retirees and other TRICARE-eligible beneficiaries who have Medicare Part A and Part B.1 For rehab, that means the two programs work as a team, and the combination covers the substance use and mental health continuum broadly.
The headline is reassuring: when a service is a benefit of both Medicare and TRICARE, you generally pay nothing out of pocket, because Medicare pays its share and TRICARE For Life pays the remainder.1
How does TRICARE For Life work with Medicare?
Through a simple order of payment. Medicare pays first, and TRICARE For Life pays second.2 What you owe depends on which program covers the service.
If both cover it, you usually owe $0. If only Medicare covers it, you owe the Medicare cost-share. If only TRICARE covers it, TRICARE For Life pays first and you owe the TRICARE deductible and cost-share. If neither covers it, you pay the full charge.2 That third case, TRICARE-only, is where residential rehab lives.
| Service | Who pays first and your likely cost |
|---|---|
| Inpatient psychiatric or SUD hospital | Medicare first, then TFL. Often $0 because both cover it. |
| Outpatient therapy and counseling | Medicare first, then TFL. Usually $0 when both cover. |
| Intensive outpatient and partial hospitalization | Medicare first, then TFL. Usually $0 when both cover. |
| Residential substance use rehab | TFL first, Medicare usually does not cover it. You owe a TRICARE cost-share. |
| Methadone and opioid treatment programs | Medicare first, then TFL. Often $0. |
Which levels does Medicare pay first, and which does TRICARE For Life cover?
Medicare carries the load on most of the continuum. Part A covers inpatient hospital psychiatric and substance use care, and Part B covers outpatient therapy, intensive outpatient, and partial hospitalization.3 On all of those, TRICARE For Life wraps around to cover the Medicare cost-shares, which is why retirees so often pay nothing.
TRICARE, meanwhile, covers the full substance use continuum, including detox, medication-assisted treatment, and residential care.4 Where Medicare and TRICARE overlap, you are in the $0 zone. Where only TRICARE reaches, you owe a TRICARE cost-share. The rules for that TRICARE side mirror our page on how TRICARE covers inpatient mental health.
What about residential rehab that Medicare does not cover?
This is the one place retirees get a bill they did not expect. Medicare’s mental health and substance use coverage runs through inpatient hospital, outpatient, intensive outpatient, and partial hospitalization, but it generally does not cover standalone residential substance use rehab the way TRICARE does.3
Because Medicare is not paying first there, TRICARE For Life steps in as the first payer under TRICARE rules, and you owe the TRICARE deductible and cost-share rather than $0.2 It is still covered. It just is not free, and knowing that ahead of time avoids the surprise.
What will you actually pay out of pocket?
For most rehab services, very little or nothing, because Medicare pays first and TRICARE For Life absorbs the Medicare deductibles and cost-shares when both programs cover the care.6 Residential substance use rehab is the main exception, where a TRICARE cost-share applies.
One honest caveat: Medicare deductibles, the Part B premium, and TRICARE cost-shares all reset every January, so any figure is a moving target.7 Confirm the current numbers on the TRICARE For Life cost matrix and Medicare’s site before you commit to a program. Where TFL sits among the plans is covered in our overview of TRICARE plan types and rehab coverage.
Do you need prior authorization?
It depends on the level of care. Residential treatment requires pre-authorization, partial hospitalization does not, and for intensive outpatient you should check with your regional contractor.8
There is one more layer for TRICARE For Life specifically. If you live in the United States or a territory, you also follow Medicare’s rules, so using Medicare-approved providers keeps the wraparound working smoothly.1
Does TRICARE For Life cover methadone, MAT, and opioid treatment programs?
Yes. Medicare has covered opioid treatment programs, including methadone, buprenorphine, and naltrexone, since 2020, and TRICARE For Life wraps around that coverage.5 Through a Medicare-enrolled program there is often no copay after the Part B deductible.
TRICARE also covers medication-assisted treatment and office-based opioid treatment on its side.4 Between the two, a retiree on TRICARE For Life has strong, low-cost access to the medications that are the backbone of opioid recovery.
Our take
Generous coverage, with one residential asterisk
For retirees, TRICARE For Life plus Medicare is close to the best rehab coverage in the system. Most of the continuum lands at $0 because Medicare pays first and TRICARE For Life mops up the rest. The single thing to plan for is residential substance use rehab, where Medicare steps back and a TRICARE cost-share applies.
Our team is independent and does not provide treatment or earn anything from referrals. We flag the residential gap because it is the one place a retiree assumes $0 and gets a bill, and a quick check of the cost matrix beforehand takes the surprise out of it.
