Where this comes up
Front-office and billing both hit this term — eligibility before the visit, prior auth before the procedure, contract terms during fee-schedule negotiation, and credentialing whenever a new provider joins or a payer roster lapses. Misses here become denials downstream.
Full definition
What it is in practice
The Mental Health Parity and Addiction Equity Act prohibits more restrictive financial requirements, quantitative treatment limits, or non-quantitative treatment limits. Enforcement has tightened in recent years.
How it shows up in your practice
If a payer's pre-auth or denial pattern for mental health appears more restrictive than for medical/surgical, parity arguments support appeal and complaint to the regulator.
