Partial Hospitalization Programs (PHP) in Montana

What is a partial hospitalization program for substance use in Montana?

A partial hospitalization program for substance use disorders in Montana is the level of care that the American Society of Addiction Medicine (ASAM) Criteria call level 2.5, meaning about 20 or more hours of clinical services a week. Care takes place in a clinic or hospital outpatient setting, not in a residential unit.

Sessions usually combine group and individual counseling, medication management and family work, and people go home at night or to a recovery residence. The ASAM Criteria are the placement standard the society publishes, and a stay is usually measured in weeks before a step down to intensive outpatient or standard outpatient care.

Many search results for partial hospitalization describe psychiatric day programs built only for mental health conditions. Their schedules and lengths serve different needs and should not be applied to substance use disorder care. Programs that treat both conditions together often appear under dual diagnosis care in Montana.

How is PHP different from IOP and residential treatment?

PHP sits between intensive outpatient care and a residential stay, both in hours and in structure.

Montana Medicaid’s July 2025 fee schedule shows how costs differ between levels. Intensive outpatient at ASAM 2.1 pays $398.17 per week. Clinically managed high-intensity residential care at ASAM 3.5 pays $264.66 per day. To compare options, see IOP listings and residential rehab in Montana.

How many hours a day is PHP, and how long does it last?

Substance use PHP in Montana usually fills a weekday block, adding up to 20 or more hours a week. Schedules vary by program, so ask what time the day starts and ends.

Your assessment sets the length, not a fixed calendar. Staff reassess progress regularly, and a stay is usually measured in weeks. It ends with a step down to intensive outpatient or outpatient care, or a move to inpatient care if your needs grow.

Why withdrawal care may come first

People who drink heavily every day, or who use benzodiazepines or opioids, may need medically managed withdrawal before day treatment. A day program does not provide overnight monitoring. An intake assessment will show which comes first, and detox in Montana lists withdrawal management across the state.

Will Montana Medicaid, Medicare or private insurance cover PHP?

Montana Medicaid is run by DPHHS as Montana Healthcare Programs. It expanded on January 1, 2016 under the HELP Act, and most members are in Passport to Health rather than a managed care plan. The fee schedule rates quoted above cover intensive outpatient and residential levels. A separate rate for level 2.5 day treatment is not among them, so ask the admissions team how a PHP bills Montana Medicaid before you start. For more, see Medicaid-accepting programs and state-funded options.

Medicare Part B has a partial hospitalization benefit, delivered through hospital outpatient departments and community mental health centers. The benefit is built mainly around mental health. Whether a substance use day program qualifies depends on how the program is set up, and Medicare rehab in Montana can help you narrow the search.

Private plans that cover substance use treatment must follow federal parity rules. These rules bar stricter limits on substance use care than on comparable medical care. Ask your insurer about prior authorization and any limit on treatment days.

How do you look up a program and plan the day?

Two state bodies oversee substance use programs in Montana. The DPHHS Office of Inspector General licenses substance use disorder facilities through its Health Care Facility Licensure section. The Behavioral Health and Developmental Disabilities Division separately grants state approval to treatment programs under 53-24-208 MCA and publishes a provider list. Ask any program which of these it holds.

Distance shapes day treatment across Montana. About four in five listed PHPs are in towns rather than cities. Nine in ten sit within 25 miles of a river, at a median of 4.9 miles, most often the Clarks Fork Yellowstone River. Billings Logan International is the nearest airport for the largest group, a median of 3.8 miles away, which can help families visiting from far corners of the state.

Daily round trips can be long in eastern Montana, where providers are sparse. Ask about transport help or telehealth sessions. Another option is a recovery residence for the nights; Montana residences can be certified through a DPHHS-recognized organization such as Recovery Access Montana. Browse sober living in Montana.

Listings show co-occurring mental health care, accepted insurers, languages and populations served wherever providers have shared them. You can compare these across all Montana listings. In a crisis, call or text 988. We could not find a separate state substance use helpline in Montana, but the national treatment referral line takes calls around the clock.
