Anthem Denied Mental Health Coverage: How to Appeal

Anthem (now Elevance Health) manages behavioral health through Anthem Behavioral Health and, in some markets, through contracted Managed Behavioral Health Organizations (MBHOs). Mental health and substance use disorder denials from Anthem are among the most contested and legally charged claim disputes in health insurance. Federal parity law — and Anthem's obligations under it — gives you powerful tools to challenge these denials.

Why Anthem Denies Mental Health Claims

Anthem's behavioral health denials most commonly arise from:

• Level-of-care determination: Anthem uses its own Level of Care criteria and MCG Health guidelines to evaluate whether inpatient psychiatric care, residential treatment, partial hospitalization (PHP), intensive outpatient (IOP), or standard outpatient therapy is medically necessary. Anthem frequently authorizes a lower level of care than your treating clinician recommends.
• No Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization: Inpatient psychiatric admissions, residential programs, PHP, and IOP require prior authorization from Anthem Behavioral Health. The behavioral health authorization number is on the back of your insurance card. Emergencies are covered without advance authorization, but notification within 24 hours is typically required.
• Concurrent review termination: For ongoing inpatient or residential stays, Anthem conducts concurrent reviews. If your treatment team does not provide timely documentation, Anthem may retrospectively deny uncertified days.
• Program not covered or not licensed: Certain behavioral health programs — wilderness therapy, certain out-of-state facilities, programs without appropriate state licensure — may be excluded.
• Out-of-network behavioral health provider: Anthem's behavioral health networks are often narrow, leading members to out-of-network providers with significantly reduced or denied benefits.

Anthem's Legal History on Mental Health Parity

Anthem has faced significant regulatory actions and litigation regarding MHPAEA compliance. Multiple states — including California, Connecticut, and others — have required Anthem to revise its behavioral health criteria following parity audits. This regulatory history strengthens your position when filing a parity-based appeal.

Your Federal Parity Rights

The Mental Health Parity and Addiction Equity Act (MHPAEA) prohibits Anthem from applying more restrictive treatment limitations to behavioral health benefits than it applies to comparable medical/surgical benefits. If Anthem's behavioral health criteria are more stringent than its criteria for comparable medical conditions — for example, requiring prior authorization for psychiatric inpatient care but not for general medical inpatient care — that is an illegal parity violation.

Under the Consolidated Appropriations Act of 2021, you can formally request Anthem's NQTL (Non-Quantitative Treatment Limitation) comparative analysis — the document showing how Anthem compares its behavioral health criteria to medical/surgical criteria. Anthem must provide this analysis within 45 days of request.
