Coverage under prefix C4B

Medicare Advantage

This prefix is associated with Medicare Advantage. MA plans combine hospital (Part A) and medical (Part B) coverage, and many include prescription drug coverage (Part D). When billing, confirm whether the plan uses the same payer ID for MA claims as for commercial claims, as many BCBS companies use separate IDs.

PPO

Under this PPO prefix, members are covered for both in-network and out-of-network care. The plan pays a higher percentage of allowed charges when members use participating providers. No gatekeeper or primary care referral is required. Verify the member's specific benefits for cost-sharing details.

POS

POS coverage under this prefix operates on a tiered system. Tier 1 (in-network with referral) provides the highest coverage. Tier 2 (in-network without referral) provides moderate coverage. Tier 3 (out-of-network) provides the lowest coverage. Verify which tier applies before submitting the claim.
