Anthem BCBS Claim Filed Too Late: How to Appeal

Why Anthem BCBS Denies Late Filing Claims

Anthem BCBS denies claim filed too late claims when it determines the request does not meet its internal coverage criteria. This may involve a medical necessity determination, a prior authorization requirement, a network limitation, or a policy exclusion.

Common Denial Reasons

• Not medically necessary: Anthem BCBS's clinical reviewers determined the service did not meet coverage criteria
• Prior authorization not obtained or denied: Advance approval was required but not received
• Out-of-network provider: The treating provider or facility is not in Anthem BCBS's network
• Plan exclusion: The service is excluded under your specific Anthem BCBS plan
• Missing documentation: Insufficient clinical records were submitted to support the claim

Steps to Appeal

1. Get the denial in writing — Request Anthem BCBS's denial letter with the specific reason and policy provision cited
2. Request the clinical policy document — Anthem BCBS must provide the internal criteria applied to your claim
3. Obtain a letter of medical necessity — Your treating physician should directly address the denial reason
4. File an internal appeal — Submit within 180 days of the denial notice. Urgent appeals must be processed within 72 hours
5. Request external review — If the internal appeal fails, request independent external review

Documents Required

• Anthem BCBS denial letter and Explanation of Benefits (EOB)
• Treating physician's letter of medical necessity
• Clinical records supporting the denied service
• Anthem BCBS's clinical policy bulletin for the denied service
• Published clinical guidelines supporting the treatment
