If you are trying to get yourself or someone you love into treatment in the Columbus area, the first question is usually not clinical. It is financial. Ohio Medicaid does cover substance use disorder treatment, including withdrawal management and residential care, and this guide explains how that coverage is structured, what the levels of care mean, and what to do next.
Nothing here tells you what your own plan will pay. Coverage depends on your specific plan, and admissions verifies your benefits before admission.
What Ohio Medicaid covers for substance use treatment
Ohio Medicaid’s substance use disorder benefit is written into the Ohio Administrative Code. Rule 5160-27-09 lists the covered service tiers, and among them are “LOC 2: intensive outpatient/partial hospitalization including LOC 2 withdrawal management (WM)” and “LOC 3: residential services/inpatient services including LOC 3 WM.”[1]
Two things in that sentence matter to a family. First, withdrawal management, what most people call detox, is a covered service, not an add-on you have to argue for separately. Second, residential treatment is covered as its own tier, so coverage does not stop the day withdrawal ends.
The rule also ties those tiers to a published clinical standard rather than to an insurer’s internal definitions. It states that services “shall be defined by and shall be provided according to the American society of addiction medicine” treatment criteria.[2] That standard, usually shortened to ASAM, is why you will see level numbers like 3.7 or 3.5 on paperwork.
What the levels of care actually mean
The ASAM numbers describe how much medical and nursing support a setting provides, not how serious a person’s substance use is. A higher number means more monitoring available on site.
At Oak Grove Recovery, the services offered are medically supervised withdrawal management and residential treatment, along with medication-assisted treatment and aftercare support. Withdrawal management here is delivered with 24/7 nursing support, and qualified medical providers evaluate medication needs and tailor medical care to each person.
Oak Grove does not offer partial hospitalization or intensive outpatient programming. If a plan of care points toward those levels, that is a conversation for the assessment, not something to sort out before you call.
Who qualifies for Ohio Medicaid
Ohio expanded Medicaid to cover low-income adults who do not qualify through another category. The state describes this group as “adults aged 19 through 64 who have Medicaid because their income is at or below 138% of the Federal Poverty Level.”[3]
One change is worth knowing about before you apply. Ohio has added a work and community engagement requirement for certain adults in that expansion group, described by the state as “a minimum of 80 hours per month as a condition of coverage.”[4] Exemptions exist, and the state’s own page is the place to check whether one applies to you. This guide does not interpret your eligibility.
Prior authorization, and why nobody can give you one answer
Prior authorization is the step where a plan agrees in advance to pay for a service. Whether it is required for residential substance use treatment depends on your specific plan and on your history of admissions this year.
Most Ohio Medicaid members are enrolled in a managed care plan, and the Ohio Department of Medicaid announced a revised utilization management framework in 2026 under which “Authorizations are only required when services exceed reasonable thresholds,” alongside a move to standardized authorization forms across plans.[5]
So the honest answer to “will I need prior authorization?” is that it depends on your plan and that the framework changed recently. Anyone who gives you a single confident answer is guessing. Admissions verifies this for you before admission.
How to apply, and what to do if you cannot wait
The Ohio Department of Medicaid directs applicants to a single online front door: “You can apply online at Benefits.Ohio.Gov.”[6] The same page lists the Ohio Medicaid Consumer Hotline at 800.324.8680 and in-person or mail application through a County Department of Job and Family Services office. In Franklin County, that is Franklin County Job and Family Services.
If someone is in immediate physical danger, or if an overdose is happening or may have happened, that is an emergency and 911 is the right call. Applying for coverage is not the first step in an emergency, and admissions can talk through options while eligibility is being sorted out.

Frequently asked questions
Does Ohio Medicaid cover detox? Yes. Ohio Administrative Code 5160-27-09 lists withdrawal management within both the LOC 2 and LOC 3 service tiers, so it is part of the covered substance use disorder benefit rather than a separate service you have to qualify for on its own.[7] What your specific plan pays still depends on your plan, and admissions verifies that before admission.
Does Ohio Medicaid cover residential treatment? Residential treatment appears in the same rule as “LOC 3: residential services/inpatient services including LOC 3 WM.”[8] Coverage of the service category is established at the state level; the details of your own authorization run through your plan.
Do I need a referral before I call? No. You can call admissions directly. An assessment determines which level of care fits, and that assessment is also what supports any authorization your plan requires.
What if my Medicaid coverage lapsed? Call anyway. Admissions works with people whose coverage status is unclear, and the state’s Consumer Hotline at 800.324.8680 can confirm where an application or renewal stands.[9]
What is ASAM, and why does it keep coming up? ASAM is the American Society of Addiction Medicine. Ohio’s rule requires substance use services to be defined and delivered according to ASAM criteria,[10] which is why level-of-care decisions are written in ASAM terms rather than in plain language. An assessment translates it.
Is Oak Grove Recovery a hospital? No. Oak Grove is a residential treatment center providing medically supervised withdrawal management and residential care with 24/7 nursing support. It is not a hospital and does not provide hospital-level care.
How long will treatment last? Length of stay is determined by medical necessity and is individualized. It is set through assessment and reviewed as care progresses, not fixed in advance.
