How to appeal a Blue Cross Blue Shield of Massachusetts ibs & functional gi 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.

MA OPP (Office of Patient Protection) provides external review separately from carriers — distinct from federal IRO process for fully-insured plans.
