How to Appeal Substance Abuse Treatment Denials
Insurance companies routinely deny or cut short substance abuse treatment despite parity law protections. Knowing your rights under MHPAEA and how to appeal effectively can be lifesaving.
Mental Health Parity and Substance Abuse
The Mental Health Parity and Addiction Equity Act (MHPAEA) requires insurers to cover substance abuse treatment at the same level as comparable medical/surgical benefits.
Common Substance Abuse Treatment Denials
- Level of care denied — insurer says outpatient is sufficient, but inpatient/residential is needed
- Length of stay cut short — insurer stops paying during treatment
- Specific facility denied — must use in-network or plan-preferred facility
- Medication-assisted treatment (MAT) denied — Suboxone, methadone, or Vivitrol not covered adequately
- Aftercare denied — IOP, PHP, or sober living not covered
How to Appeal
- Cite MHPAEA — if comparable medical conditions would get inpatient care, substance abuse should too
- Document clinical severity — ASAM criteria level for your patient supports the level of care
- Clinical assessment — include comprehensive substance abuse evaluation
- Treatment history — show failed outpatient attempts if requesting higher level
- Provider recommendations — treating provider's clinical judgment about needed level of care
- Request expedited appeal — substance abuse treatment delays can be life-threatening
Parity Violations to Watch For
- Requiring prior authorization for substance abuse but not comparable medical conditions
- Limiting residential treatment days while not limiting rehabilitation hospital days
- Applying more restrictive medical necessity criteria to substance abuse than medical/surgical
