Substance Abuse Treatment Services Covered By Medicaid In Montana

Montana Medicaid covers residential programs, outpatient treatment, medical detox, medication-assisted treatment using buprenorphine or naltrexone, dual diagnosis care for co-occurring mental health disorders, individual and group therapy, medical care, support groups, and recovery coaching.

The Montana Department of Public Health and Human Services (DPHHS) states that Montana Medicaid covers substance abuse and mental health services.

How To Use Medicaid To Cover Drug Treatment In Montana

Using your Montana Medicaid benefits to pay for addiction treatment works just like using any other health insurance. When you’re ready to enter a rehab program, simply provide your Medicaid information to the treatment facility you want to attend. The rehab center will then contact Medicaid directly to verify your coverage and discuss your treatment plan.

Some services may require prior authorization, which means the facility needs approval from Medicaid before providing certain types of care, but the treatment center handles this process for you.

Cost Of Addiction Treatment At A Montana Medicaid Rehab Center

Montana Medicaid is designed for people with limited income, and there are household income limits you must meet to qualify for benefits. Once enrolled, most people receive addiction treatment services with little to no out-of-pocket costs. However, depending on your specific income level compared to the Federal Poverty Level, you may owe small co-payments for some services.

If your annual household income is below 100% of the Federal Poverty Level, you may pay $4 for outpatient services, $75 for inpatient services, $4 for preferred brand-name medications, and $8 for non-preferred brand-name drugs. If your income is above 100% of the Federal Poverty Level but you still qualify for Medicaid, you may owe up to 10% of the cost of services you receive.

Montana law protects you from excessive costs. You will never be asked to pay co-payments totaling more than five  percent of your annual household income, ensuring treatment remains affordable.

Medicaid Requirements For Montana Residents

To qualify for Montana Medicaid, you must be a U.S. citizen or legal resident living in Montana and meet income requirements based on your household size. You must also fit into at least one eligible category: pregnant women, parents or caretakers of children 18 or younger, people who are blind, individuals with disabilities, or adults 65 or older. Montana’s expanded Medicaid also covers many low-income adults without children.
