Key takeaway
Insurance rarely pre-promises a full marketing length of rehab. Plans often authorize a block of days, then review again based on medical necessity. Ask how concurrent review works and what you owe if days are denied. Call or text (800) 653-9376 for help listing authorization questions.

How length usually works
An initial authorization, then concurrent review with clinical updates. Your share can change if days are denied. See does insurance cover inpatient rehab.
What to ask
- How many days are authorized today?
- When is the next review?
- What is my responsibility if denied?
- What step-down is planned?
Appeals
Ask for criteria and deadlines. Parity consumer materials explain rights at a high level.

Common Questions
Will my plan pay for 30 days automatically?
Usually not automatically. Authorization length depends on clinical criteria and plan rules. See 30-day rehab cost.
What is concurrent review?
The plan checks during a stay whether continued days remain medically necessary.
What if authorization ends early?
Ask about appeal rights, step-down to PHP or IOP, and your financial responsibility in writing.
Do parity laws guarantee a length?
Parity limits discriminatory management; it does not guarantee a set number of days.
How can I prepare?
Get initial auth in writing and ask the facility how they handle extensions.
