How Oklahoma Programs Handle Cost

Each count comes from the payment details programs report in our directory. The counts overlap: a program with a sliding scale that also takes Medicaid appears in both. When one organization lists a site more than once, it counts once.

Who Qualifies for Free Treatment

There's no single national rule. Each state runs its own publicly funded treatment system and sets its own eligibility rules. In Oklahoma, Oklahoma Department of Mental Health and Substance Abuse Services (ODMHSAS) oversees publicly funded substance use services.

Federal rules do set some priorities. Programs that get SAMHSA substance use block grant funds and serve women have to give pregnant women preference for admission. Funded programs that serve people who inject drugs give treatment preference in this order:

  1. Pregnant women who inject drugs
  2. Other pregnant women with a substance use disorder
  3. People who inject drugs
  4. Everyone else

A program that reports "no payment accepted" doesn't charge patients. Government-run programs may still bill insurance or use a sliding scale, and eligibility can depend on where you live, your income and whether you're insured. Ask before you go.

How to Apply in Oklahoma

Oklahoma Department of Mental Health and Substance Abuse Services (ODMHSAS) is the Oklahoma agency for publicly funded substance use treatment. Visit the Oklahoma Department of Mental Health and Substance Abuse Services (ODMHSAS) website for help finding treatment.

  1. Call a program from the list above. Ask whether it has openings, what it charges and whether you qualify for a reduced or no-cost fee.
  2. Have your ID, proof of income and any insurance or Medicaid card ready. Programs may ask for them at intake.
  3. If you don't have insurance, contact SAMHSA's National Helpline. It's free, confidential and open 24/7, and it can refer you to Oklahoma Department of Mental Health and Substance Abuse Services (ODMHSAS), which handles state-funded treatment.
  4. If you might qualify for Medicaid, apply now rather than waiting. Apply for SoonerCare.

Oklahoma Medicaid and Addiction Treatment

143 of the 179 Oklahoma programs in our directory say they accept Medicaid, and 87 accept a state-financed health plan other than Medicaid. Oklahoma's Medicaid program is SoonerCare.

State Medicaid programs cover addiction treatment to different degrees. Whether detox, residential care, outpatient programs or medication for opioid use disorder are covered depends on Oklahoma's rules and your plan, so check with both the program and your plan. Check eligibility and apply.

In Oklahoma, substance use treatment programs are licensed or certified by Oklahoma Department of Mental Health and Substance Abuse Services, Provider Certification. Check the state's provider list.

Frequently Asked Questions

Is rehab free in Oklahoma?

Some programs are. Of the 179 Oklahoma programs in our directory, 9 report that they accept no payment, and 37 are run by a state, county, tribal or federal agency. Of the government-run programs, 5 are run by the VA, the Department of Defense or the Indian Health Service. Those programs serve only eligible veterans, military health system patients or American Indian and Alaska Native patients. Government-run programs can still bill insurance or charge on a sliding scale, so ask about cost when you call. If you have no insurance, SAMHSA's National Helpline (see samhsa.gov) can refer you to Oklahoma Department of Mental Health and Substance Abuse Services (ODMHSAS), which handles state-funded treatment.

Does Oklahoma Medicaid cover rehab?

143 of the 179 Oklahoma programs in our directory say they accept Medicaid. Oklahoma's Medicaid program is SoonerCare. State Medicaid programs cover addiction treatment to different degrees, so ask the program and your Medicaid plan which services are covered before you start.

How much does rehab cost without insurance?

It depends on the type of care, how long it lasts and the program itself. Outpatient care usually costs less than a residential stay. In Oklahoma, 73 programs in our directory use a sliding fee scale based on income, and 81 offer payment assistance. Ask for the self-pay rate and whether you qualify for a reduced fee before you're admitted.

Who gets priority for state-funded treatment?

Under federal block grant rules, programs that get block grant funds and serve women must give pregnant women preference for admission. Funded programs that serve people who inject drugs give treatment preference in this order: pregnant women who inject drugs, other pregnant women with a substance use disorder, people who inject drugs, and then everyone else (45 CFR 96.131). Other eligibility rules vary by state, so ask the program or Oklahoma Department of Mental Health and Substance Abuse Services (ODMHSAS).

What is the difference between a sliding fee scale and payment assistance?

A sliding fee scale sets what you pay based on your income and other factors. Payment assistance varies more: each program decides what help it offers, so ask what's available and what paperwork you'll need.

Are there options for veterans and tribal members?

Yes. Veterans can ask the VA about substance use treatment through VA health care. American Indian and Alaska Native people can contact the Indian Health Service or a tribal health program about alcohol and substance use services.
