Substance use disorder treatment is not a single event , it is a progression through levels of care, each designed for a different stage of recovery. TRICARE covers all of them. Understanding what each level is, what TRICARE pays, and when you need authorization helps you plan your treatment without surprises.
Coverage information is drawn from TRICARE.mil , Substance Abuse. Always verify current coverage and prior authorization requirements with TriWest at 1-888-874-9378 before entering any level of care.

Medical detox
Medical detox is the medically supervised process of clearing the substance from your body while managing withdrawal safely. It is not treatment for the underlying addiction , it is stabilization. TRICARE covers medical detox as an inpatient benefit, meaning coverage for the clinical services provided, not for room and board above what the clinical rate covers.
Prior authorization is required before entering a detox facility. For a true medical emergency, you seek care first and notify TRICARE within 24 hours. For planned detox , which is most cases , call TriWest at 1-888-874-9378 before admission, have your TRICARE ID and the facility’s name ready, and get an authorization number before you check in.
For active-duty service members, the branch substance abuse programs (Army ASAP, Air Force ADAPT, Navy and Marine Corps SARP) coordinate detox referrals when needed. See our full guide on what happens during medical detox day by day.
Residential treatment
Residential treatment is 24-hour structured clinical programming at a facility where the person lives during treatment. This is what most people mean when they say rehab. TRICARE covers residential treatment as a benefit based on medical necessity. There is no fixed maximum number of days , coverage continues as long as inpatient care is clinically appropriate and the facility documents that through continued stay reviews.
Prior authorization is required before admission. The facility typically handles this process, but you should verify it has been obtained before your first day. TRICARE Select cost-sharing for residential treatment is the lesser of $535 per day or 25 percent of the allowable charge, after the annual deductible. Active-duty service members on TRICARE Prime pay nothing.
Continued stay reviews happen approximately every 5 to 7 days. The facility’s clinical staff submit documentation to TriWest certifying ongoing medical necessity. If a continued stay review results in a denial , TRICARE decides the person no longer needs that level of care , the facility should assist you in appealing that decision or transitioning to the next appropriate level.
Partial hospitalization (PHP)
PHP is typically a 5-to-6-hour structured treatment program, 5 days per week, where the person returns home or to a sober living environment each evening. It is appropriate after completing residential treatment when significant clinical structure is still needed, or as a first level of care when residential treatment is not clinically required.
TRICARE covers PHP under both the mental health and substance use disorder benefits. Prior authorization is typically required. Cost-sharing is generally 20 to 25 percent of the allowable charge per day for TRICARE Select beneficiaries. PHP is often one of the most cost-effective covered levels of care relative to the clinical intensity it provides.
Intensive outpatient (IOP)
IOP typically involves 3-hour group and individual therapy sessions, 3 to 4 days per week. The person continues living at home and can maintain work and family responsibilities. IOP is appropriate as a step-down from PHP, or as an initial level of care for people who do not need a higher level of clinical intensity.
TRICARE covers IOP as an outpatient benefit. Prior authorization is often required , confirm with TriWest before starting. Cost-sharing is typically 20 to 25 percent of the allowable charge for TRICARE Select. For TRICARE Prime family members with a referral, co-pays are modest. TRICARE Prime active-duty members pay nothing.
IOP allows people to maintain their normal life while in structured treatment, making it compatible with military work schedules when the duty station permits it.
Standard outpatient therapy
Standard outpatient therapy is individual or group counseling sessions, typically weekly. This level of care supports ongoing recovery after completing a higher level, or is appropriate for people with less severe substance use disorders who do not require more intensive programming.
Standard outpatient therapy generally does not require prior authorization. TRICARE Select beneficiaries pay a co-pay per visit, typically $25 to $35. TRICARE Prime family members pay a smaller co-pay at civilian network providers. Active-duty pay nothing.
Long-term outpatient therapy , continuing to see a counselor or therapist throughout recovery , is a significant factor in sustained recovery outcomes and is a covered benefit with no predetermined limit as long as it is clinically supported.
Medication-assisted treatment (MAT)
TRICARE covers FDA-approved medications for substance use disorder, including buprenorphine (Suboxone), naltrexone (Vivitrol), and methadone when dispensed through a licensed opioid treatment program. These medications can be ongoing, meaning the person takes them for months or years as part of a sustained recovery plan.
MAT does not require a specific level of care to be covered , it can be prescribed in an outpatient setting alongside counseling. Some medications require prior authorization depending on the plan and the specific drug. TRICARE’s pharmacy benefit covers most MAT medications at the standard co-pay for the formulary tier. See the TRICARE Pharmacy Program at tricare.mil for formulary and co-pay details.
How prior authorization works across levels
Prior authorization is required for inpatient levels (detox and residential) under all TRICARE plans. PHP and IOP often require it as well. Standard outpatient therapy generally does not. When transitioning between levels , from residential to PHP, or PHP to IOP , a new authorization may be required for the next level. The facility’s clinical team should manage this transition, but you should confirm it is happening before the transition date.
If TRICARE denies authorization for a level of care you and your provider believe is necessary, you have the right to appeal. See our guide on how to appeal a TRICARE denial for the specific steps and deadlines.
