How Do I Verify My Insurance Benefits for Rehab?
Calling your insurance company before your loved one enters treatment is not just recommended, it is essential. It is the only way to know exactly what will and won't be covered, what your out-of-pocket costs will be, and whether the specific facility you have in mind is in-network. This guide walks you through the process step by step, including the exact questions to ask.

What to Have Ready
Before calling your insurance company, gather the following. Having everything ready will make the call faster and more productive.
Insurance Card
The member ID number, group number, and the member services phone number (usually on the back of the card). This is the number you will call.
Pen and Paper (or Notes App)
Write down everything, representative name, date and time of the call, reference number, and every answer to every question. These notes are critical if you need to appeal a decision later.
Facility Name and NPI
If you have a specific treatment facility in mind, have its name and National Provider Identifier (NPI) number ready. The NPI is how insurers identify providers in their system. You can look up NPIs at npiregistry.cms.hhs.gov.

Exactly What to Ask — Question by Question
Ask to speak with a behavioral health or substance use disorder benefits specialist, not just a general customer service representative. General reps often don't have detailed knowledge of addiction treatment benefits. Write down the name of the representative and a call reference number before asking any questions.
Basic Coverage Confirmation
- "Does this plan cover substance use disorder treatment?"
- "Is there a separate behavioral health or substance use disorder deductible?"
- "What is my deductible for behavioral health, and how much have I met so far this year?"
- "What is my copay or coinsurance for inpatient treatment? For outpatient?"
- "Is there an out-of-pocket maximum for behavioral health benefits?"
Level of Care Coverage
- "Does this plan cover medically supervised detox? Inpatient/residential treatment? Partial hospitalization (PHP)? Intensive outpatient (IOP)? Standard outpatient?"
- "Are there any day or visit limits for any of these levels of care?"
- "Is coverage for any level of care based on medical necessity?"
- "Which criteria does the plan use to determine medical necessity for residential treatment, the ASAM criteria?"
Prior Authorization
- "Does any level of addiction treatment require prior authorization?"
- "If so, what information is needed for the authorization request?"
- "How far in advance must authorization be requested?"
- "What is the turnaround time for authorization decisions?"
- "Is there an expedited authorization process for urgent situations?"
In-Network vs. Out-of-Network
- "Does this plan cover out-of-network addiction treatment?"
- "If so, what is the out-of-network benefit, is there a separate deductible?"
- "Is [specific facility name and NPI] in-network for this plan?"
- "If [facility] is not in-network, can I request a single-case agreement to treat them as in-network?"
Medication-Assisted Treatment (MAT)
- "Does this plan cover medications for opioid use disorder, buprenorphine (Suboxone), methadone, naltrexone?"
- "Is prior authorization required for MAT medications?"
- "Are there quantity limits on MAT prescriptions?"
- "Is step therapy required before MAT is covered?"
What to Do With What You Learn
Get It in Writing
After the call, request a written summary of the benefits explained to you, by email or through the insurer's online portal. Verbal representations can be disputed later; written confirmation is far stronger. If the insurer won't provide written confirmation, that itself is worth noting.
Share With the Treatment Team
Give Banyan's admissions team your benefits verification notes. They can identify potential coverage gaps, anticipate prior authorization requirements, and help structure the admission process to maximize what your insurance covers.
Know the Appeals Process
Before admission, ask the insurer: "If treatment is denied or authorization is not extended, what is the appeals process?" Understanding this before you need it saves critical time when the moment arrives. See our guide on appealing an insurance denial for details.
