How to Appeal a Mental Health Insurance Denial
A mental health denial means your insurer has refused to cover or has limited coverage for mental health or substance use disorder treatment. This can include therapy sessions, psychiatric medication, inpatient treatment, or substance abuse rehabilitation.
The Mental Health Parity and Addiction Equity Act (MHPAEA) requires insurers to cover mental health and substance use disorder services at the same level as medical/surgical services. Despite this law, mental health denials remain disproportionately common.
54% of mental health denials are overturned, and parity violation complaints have a particularly high success rate.
Your Legal Rights
The Mental Health Parity and Addiction Equity Act (MHPAEA) requires that insurers cannot impose stricter limitations on mental health benefits than on medical/surgical benefits. This includes visit limits, prior authorization requirements, and cost-sharing. The ACA designates mental health as an essential health benefit. Your state may have even stronger parity protections.

- 2Cite the MHPAEA specifically — insurers are required to provide equal coverage.
- 3Get a letter from your mental health provider explaining medical necessity.
- 4If visit limits are the issue, compare them to limits on comparable medical services.
- 5File the appeal citing both MHPAEA and ACA essential health benefit requirements.
- 6File a complaint with your state insurance department if the insurer violates parity.
