Coverage under prefix B9K

HDHP

This prefix is associated with a High-Deductible Health Plan. HDHP members pay more out-of-pocket before insurance coverage begins. These plans are commonly paired with HSA or HRA accounts. When billing, be aware that the member may have significant cost-sharing responsibility until their annual deductible is satisfied.

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.

HMO

This prefix is linked to an HMO plan. Health Maintenance Organization coverage requires members to use in-network providers and coordinate care through a designated primary care physician. Referrals are typically required for specialist visits. Claims submitted without proper referral documentation may be denied.
