Coverage under prefix W6Z

Traditional Indemnity

Traditional indemnity coverage under this prefix is a fee-for-service plan. Members can see any provider without network restrictions or referral requirements. The plan reimburses a set percentage of usual and customary charges. Claims are submitted directly to the payer listed above.

Medicaid

This prefix is associated with Medicaid managed care. When a BCBS plan administers Medicaid, the claims process may differ from commercial coverage: different payer ID, different claims address, different prior authorization rules, and different timely filing limits. Always verify Medicaid-specific details before submitting.

HMO

HMO coverage means this member must use providers within the plan's network. A primary care physician serves as the care coordinator and must authorize specialist referrals. Emergency services are the primary exception to the network requirement. Always verify referral status before providing non-emergency specialty care.
