Coverage under prefix C4X

HDHP

HDHP (High-Deductible Health Plan) coverage means the member has a higher deductible than traditional plans, often paired with a Health Savings Account (HSA). Most services require the member to pay out-of-pocket until the deductible is met. Preventive care is typically covered before the deductible. Submit claims normally to the payer listed above.

Medicaid

Medicaid coverage under this prefix means the member's Medicaid benefits are administered by a BCBS managed care plan. Medicaid managed care claims may have different submission requirements, payer IDs, and timely filing deadlines than commercial claims. Verify the specific Medicaid plan details with the payer.

Medicare Advantage

This prefix includes Medicare Advantage coverage. MA plans follow CMS guidelines for timely filing (365 days from date of service), which may differ from the commercial plan's deadline. The payer ID for Medicare Advantage claims may differ from the standard commercial payer ID. Verify before submitting.
