Quick answer
Devoted Health sells Medicare Advantage plans, so it covers the medically necessary substance use treatment that Original Medicare covers and often more. Devoted lists individual and group counseling, medications to treat substance abuse, medication management visits, and outpatient and inpatient hospital care. Medicare Advantage plans may require prior authorization, and plan availability is by county.

You are on Medicare, Devoted Health is your plan, and you are trying to find out whether it will pay for detox or treatment. The reassuring part is the baseline: because Devoted sells Medicare Advantage plans, it has to cover what Original Medicare covers, and Medicare covers substance use disorder treatment. The part to pin down is your plan's own rules — what it lists, what needs approval, and what costs you share.
Does Devoted Health cover rehab and detox?
It depends on your plan and the level of care, but the baseline is solid. Medicare Advantage plans must cover all medically necessary services that Original Medicare covers, and they can add benefits beyond that. Devoted Health publishes a behavioral health benefit that includes the addiction services most people are asking about, from counseling to inpatient hospital care. If the service is medically necessary under Medicare's standards, a Medicare Advantage plan cannot simply decline it under a stricter internal rule.
What Devoted Health lists for substance use
Devoted Health's mental and behavioral health page sets out what its plans cover for substance abuse and addiction. The published list includes:
- Individual and group counseling for substance use
- Medications to treat substance abuse
- Visits with your provider to manage those medications
- Outpatient and inpatient hospital services for substance abuse
- Partial hospitalization program (PHP) — structured services in a hospital during the day, going home at night
- Inpatient hospitalization when around-the-clock care is needed
The same page notes that therapy, including family and group therapy, does not require a referral, and that medications for mental health conditions are covered like other medications on the plan's covered drug list.
What Medicare covers underneath
Because Devoted is a Medicare Advantage plan, the federal benefit is the floor. Medicare publishes what Part A and Part B cover for substance use disorder:
- Part A (hospital insurance) covers services you receive when admitted to a general or psychiatric hospital as an inpatient.
- Part B (medical insurance) covers inpatient services from a doctor while you are in the hospital, intensive outpatient program services at a hospital, community mental health center, federally qualified health center, rural health clinic or opioid treatment program, outpatient services you might get as part of substance use disorder treatment, and partial hospitalization services that meet certain requirements.
- Opioid use disorder medications. Part B covers methadone, buprenorphine and naltrexone when you get them in a doctor's office or through an opioid treatment program, and it covers nalmefene and naloxone to reverse an overdose. Part A covers those medications when you receive them as an inpatient at the hospital.
That is the benefit package a Medicare Advantage plan is measured against. Devoted can offer more, and most Medicare Advantage plans do, but it cannot offer less.
Prior authorization, and what you pay
Medicare Advantage differs from Original Medicare in two ways that matter when you are trying to get into treatment.
First, your plan may require approval before it covers certain services. Original Medicare generally does not require prior authorization, but Medicare Advantage plans may, and a residential or hospital-based program is the kind of service that often needs it. The 2024 CMS rule also limits how plans use medical necessity criteria — they must follow Medicare's national and local coverage determinations and cannot apply criteria more restrictive than Original Medicare's.
Second, your costs differ. Medicare Advantage plans set their own copays and coinsurance and have a yearly limit on what you pay for covered Part A and Part B services. Costs vary by plan, so confirm the numbers for your plan instead of assuming.
Who can join, and where
Devoted Health is a Medicare Advantage HMO and/or PPO plan with a Medicare contract. To join, you generally need to be entitled to Medicare Part A and enrolled in Medicare Part B, and you have to live in the plan's service area. Devoted also offers dual eligible special needs plans (D-SNPs) for people who have both Medicare and Medicaid, and it says its D-SNPs have contracts with state Medicaid programs.
Availability is by county, not statewide. Devoted Health announced it served more than 466,000 members across 29 states as of January 2026, and its published service area includes select counties in states including Florida, Ohio and Pennsylvania. If you are not sure whether a Devoted plan covers your county, the plan's service area page and your plan documents settle it.
One more note if Medicaid is also in the picture: Medicare Advantage enrollment is tied to Medicare, and Medicaid eligibility is decided separately by your state. If you qualify for both, a D-SNP may bundle the two.
How to start
Devoted Health members can call 1-800-338-6833 (TTY 711) to find a provider or understand benefits, or chat through the MyDevoted member account. Ask whether the level of care you need is covered, whether it requires prior authorization, and what you will owe.
