Anthem Elevance Coverage Determinations
Anthem Elevance Coverage Determinations: Overview
Anthem Elevance Health (formerly Anthem Blue Cross and Blue Shield) is a multi-state BCBS operation with a 23% overall denial rate. Coverage lookup is performed on a per-state basis, as plan designs and authorization requirements vary by contract. Most determinations are available through the provider portal, with a small number requiring telephonic review.
Key Requirements
- State-Specific Rules: Anthem Elevance operates in 14+ states under separate regulatory frameworks. Coverage policies differ by state and plan design.
- Portal Access: Use providers.anthem.com, integrated with Availity. Login credentials may vary by state contract.
- Service Codes: Enter CPT/HCPCS codes for your planned service. Some codes require pre-authorization; others do not.
- Prior Auth Coordination: Coverage determination is distinct from prior authorization. A covered service still requires PA if billed within the lookback period.
- Plan Verification: Verify the plan line of business (HMO, PPO, EPO) before lookup, as benefits differ by product.
