How to appeal a CareFirst BCBS pediatric oncology denial

The framework that applies to your appeal

Federal law gives you the right to a full and fair internal appeal, then an external review by an independent third party.

CareFirst BCBS-specific note: BCBS licensee for Maryland, DC, and northern Virginia (~3.5M members). Operates as non-profit. Appeals jurisdiction depends on policy issue location — MIA (MD), DISB (DC), or SCC Bureau of Insurance (VA). CVS Caremark is the PBM.

How to submit the appeal to CareFirst BCBS

1. Read the denial letter — note the exact denial reason code and the appeal deadline (180 days from the date on the letter).
2. Gather supporting documentation: physician letter of medical necessity, relevant clinical notes, peer-reviewed citations supporting the treatment for your indication, and the policy or coverage document CareFirst BCBS cited in the denial.
3. File the appeal through CareFirst BCBS's portal (members: https://member.carefirst.com ; providers: https://provider.carefirst.com). Standard decision returns within 30 days; expedited urgent appeals return within 72 hours.
4. If denied again, request external review by an independent reviewer within 4 months of the final internal denial. In MD, the state insurance department coordinates external review for fully-insured plans; ERISA self-funded plans use a federal external review through DOL/EBSA.
