Coverage under prefix C7D

Medicaid

Under this prefix, the member may have Medicaid coverage managed by this BCBS plan. Medicaid claims have specific rules around cost-sharing, balance billing, and timely filing that override the plan's standard commercial policies. Contact the plan's Medicaid provider services line for submission details.

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.

Traditional Indemnity

Traditional indemnity coverage means the member has fee-for-service insurance with no network limitations. Any licensed provider can be seen without referrals. Claims are reimbursed based on usual, customary, and reasonable (UCR) charges. The member typically pays a deductible and a percentage of allowed charges.
