Common Questions
Does Medicaid cover residential rehab?
In many states yes for some members when medically necessary, with utilization review. Not universal.
How long will Medicaid pay?
Often day-by-day or week-by-week concurrent review, not a prepaid package.
What if the facility has more than 16 beds?
IMD payment limits may apply for adults 21-64 unless a state option or waiver covers the stay.
What are alternatives if residential is denied?
PHP, IOP, outpatient counseling, OTP, and office-based MOUD. Appeal the denial in parallel.
How do I compare programs?
Ask about ASAM level, MOUD access, discharge planning, and whether they take your specific managed care plan.
