You’ve found a treatment program, you’ve checked your insurance, and then you hear a new term: prior authorization. It’s a common step between deciding to get help and starting treatment, and it’s often misunderstood. Knowing how it works can take some of the uncertainty out of the admissions process.
What Prior Authorization Is
Prior authorization, sometimes called pre-certification or pre-approval, is a health plan’s process for confirming that a service is medically necessary before agreeing to pay for it. For addiction and mental health treatment, the plan reviews clinical information about your needs and decides whether the requested level of care fits.
It isn’t a judgment of whether you deserve help. It’s an administrative step that plans use for many kinds of care, including surgeries, imaging and hospital stays.
Which Levels of Care Commonly Require It
Requirements vary widely from plan to plan, but in general:
- Medical detox and residential treatment commonly require prior authorization.
- Partial hospitalization programs often require it as well.
- Intensive outpatient programs, including virtual IOP, may or may not, depending on the plan.
- Routine outpatient therapy visits often don’t, though some plans review them after a certain point.
Who Handles the Request
In most cases, the treatment provider submits the prior authorization request to your plan, often by phone or through an online portal. You’ll usually be asked to sign consent forms that allow the provider to share clinical information with your insurer. You can also call your plan yourself to ask what’s required and how the process works for your specific benefits.
What Insurers Look At
Plans use clinical criteria to decide whether a level of care is appropriate. For substance use treatment, many plans rely on criteria developed by the American Society of Addiction Medicine (ASAM), which look at a person’s needs across several areas. Reviewers commonly consider:
- Risk of serious withdrawal, especially from alcohol or benzodiazepines, which can be life-threatening
- Physical health conditions that affect safety or treatment
- Mental health symptoms, including depression, anxiety, trauma or thoughts of self-harm
- Readiness and ability to engage in treatment
- Risk of continued use or relapse without more structured support
- Whether the home environment supports recovery
Honest, complete answers during your assessment help the clinical team describe your needs accurately. There’s no advantage in downplaying symptoms, and doing so can lead to a level of care that doesn’t fit.
How You Can Help the Process Go Smoothly
Most of the work of prior authorization happens between the treatment team and your plan, but a few simple steps on your end can prevent delays:
- Have your insurance card and a photo ID ready when you call admissions.
- Share a complete list of medications, including doses, along with any recent substance use.
- Mention past treatment, hospital stays or withdrawal symptoms, since this history can matter to a reviewer.
- Sign the release forms that allow your provider to talk with your plan.
- Keep your phone nearby in case the plan or the treatment team needs to reach you.
Timing and Urgent Requests
Standard requests may take longer to process, while urgent requests are generally reviewed on a faster timeline. When someone needs care quickly, the provider can ask the plan to treat the request as urgent. Some plans also allow notification shortly after an urgent admission instead of approval beforehand. Your plan’s rules determine which approach applies.

Concurrent Review: Authorization Doesn’t End at Admission
Approval is usually granted for a certain number of days or sessions at a time. As treatment continues, the plan conducts concurrent reviews, checking progress and deciding whether to extend care at the current level or approve a step down. For example, someone might move from residential care to a partial hospitalization program and then to a virtual intensive outpatient program as symptoms improve and skills grow.
These reviews happen in the background for most people in treatment. Knowing they exist can help you understand why your care team documents progress closely and why the length of each stage can vary.
If a Request Is Denied
A denial can feel like a closed door, but you usually have options:
- Peer-to-peer review: a clinician involved in your care speaks directly with the plan’s reviewer to discuss your needs.
- Internal appeal: you or your provider ask the plan to reconsider, often with additional records or a letter of medical necessity.
- Expedited appeal: in urgent situations, plans generally must decide faster.
- External review: if the plan upholds the denial, you may be able to request an independent review.
It’s also reasonable to ask whether a different level of care would be approved in the meantime so you aren’t left without support.
Frequently Asked Questions
Does prior authorization mean my treatment will be paid for?
Not exactly. It confirms medical necessity, but payment still depends on your eligibility, benefits, deductible and other plan terms on the dates of service.
Can I start detox before approval comes through?
If you’re experiencing a medical emergency, such as a seizure, severe confusion or trouble breathing, call 911 right away. For urgent but non-emergency situations, talk with the admissions team about your options.
Does virtual IOP need prior authorization?
Some plans require it and some don’t. Ask about virtual care specifically when you verify benefits.
Can I request my plan’s criteria?
Yes. You can generally ask your plan for the medical necessity criteria it used to make a decision about your mental health or substance use care.
