Plan Types & Coverage Differences

Blue Cross Blue Shield of North Carolina offers different plan types that affect how you access Bylvay:

HMO Plans: Require referrals from your primary care physician to see specialists like hepatologists or pediatric gastroenterologists. You'll need this referral before pursuing Bylvay coverage.

PPO Plans: No referral required, but staying in-network reduces costs. You can directly schedule with a hepatologist who treats PFIC or Alagille syndrome.

Key Consideration: All BCBS NC plans follow the same specialty drug prior authorization process for Bylvay, regardless of plan type. The main difference is how you access the prescribing specialist.
