The short answer
How does insurance coverage for rehab work?
Most commercial plans cover some addiction and mental health treatment, and what yours pays depends on the plan and the level of care.
The federal parity law says a plan that covers mental health and addiction treatment can't limit it more strictly than it limits medical care. It doesn't mean every service is covered, or that treatment is free.
In network
Enhance is in network with most insurance plans, and admissions checks your member ID to confirm your plan is one of them. If your plan isn't listed here, call us and we'll check it for you.
Out of network
An out-of-network plan may pay less or nothing, and you can be billed for the difference. Admissions asks your plan what it pays out of network and tells you before you decide.
We're also in network with Optum, which often manages the behavioral health benefit on UnitedHealthcare cards.
How your plan type affects rehab coverage
The type of plan printed on your card shapes which providers you can see and what you need before treatment starts.
PPO plans
You can usually see in-network or out-of-network providers without a referral, though out-of-network care often costs more.
HMO plans
Care usually has to stay in the plan's network, and some HMOs need a referral from your primary doctor first.
EPO plans
Care usually has to stay in the plan's network, but you often do not need a referral to start.
Covered California plans
Marketplace plans must include mental health and substance use treatment as essential health benefits under federal law.
Employer plans
Plans through work, including CalPERS for California public employees, set their own networks and prior authorization rules.
Separate behavioral health companies
Some cards name a second company, such as Optum or MHN, that manages the mental health and addiction benefit.

Insurance terms that affect what you pay
A few terms in your insurance plan decide how much you pay for treatment.
- The deductible is what you pay before the plan pays.
- A copay is a set amount per visit or per day.
- Coinsurance is the share of the bill you pay after the deductible.
- Prior authorization is your plan's approval before a level of care starts.
- Medical necessity is the test your plan uses to decide whether it will pay.
What we won't promise before we check your plan
- A copay, a deductible, or a daily rate.
- That your plan will pay a claim.
- How many days your plan will cover.
If there is immediate danger, call 911 or go to the nearest emergency room. For a mental health crisis, call or text 988.

Common questions about rehab coverage
If your question is not answered here, call admissions at (714) 862-1907.
How long will insurance pay for inpatient rehab?
Your plan sets the number of days, and it varies from plan to plan. Admissions asks your plan and tells you what it says.
Why do plans deny rehab?
Common reasons include a missing prior authorization, a level of care the plan says isn't medically necessary, or a benefit the plan never included. A denial is the plan's decision, and we can't promise to overturn it.
How much does rehab cost after insurance?
It depends on your deductible, copay, and coinsurance, and on whether your plan covers the care. Admissions gets those figures from your plan when it checks your benefits.
Do I need a referral?
Some HMO plans require one, so bring it if you have it. If you don't have one, admissions will tell you whether your plan requires it before you start.
What does the Mental Health Parity Act require?
A plan that covers mental health and addiction treatment can't give it tighter limits, such as higher copays or fewer visits, than it gives comparable medical care.
What is the difference between in-network and out-of-network coverage?
In network means the provider has a contract with your plan, so you usually pay less. Out of network usually costs more, and you may be billed the difference.
What is prior authorization?
It is your plan's approval before a level of care starts. Admissions asks whether your plan requires it for the level you need before treatment begins.
Does insurance cover inpatient mental health care?
Many plans cover it when they agree it is medically necessary, often after prior authorization. Admissions checks what your plan requires before you start.
Does insurance cover PHP or IOP?
Many plans cover partial hospitalization and intensive outpatient care, often with prior authorization. Admissions checks what your plan pays for each level before you start.
Does insurance cover dual diagnosis treatment?
Plans that cover mental health and addiction treatment usually cover care for both together. Admissions checks your benefits for both conditions on the same call.
Are medications covered by insurance?
Many plans cover prescribed medication through a pharmacy benefit with its own copays. Your plan's drug list, called a formulary, shows which medications it covers.
How do deductibles and out-of-pocket maximums affect what I pay?
You pay covered costs up to your deductible before most coverage starts. Once you reach the out-of-pocket maximum, the plan pays covered in-network care in full for the rest of the plan year.
Does insurance verification guarantee coverage?
No. Verification tells you what your plan says it covers today, and the plan still decides whether to pay each claim.
What information do I need to verify my benefits?
Have your member ID, the name on your card, the plan type printed on it, and the kind of care you are looking for.
Can I appeal if my insurer denies coverage?
Yes. Your plan must explain a denial and tell you how to appeal it. In California you can also ask the state for an independent medical review.
Can I have more than one insurance plan?
Yes. When you have two plans, one pays first and the other may cover some of what is left, so give admissions both cards.
Does Medi-Cal or Medicare cover addiction treatment?
Both cover some addiction treatment. Admissions can tell you whether Enhance can work with your plan, and help you find another program if not.
What if I don't have insurance?
Call admissions anyway. They can talk through your options and help you find a program that fits if Enhance is not the right one.
Have admissions check your plan
Call with your insurance card in hand. Admissions will tell you what your plan covers before you agree to anything.
