Coverage under prefix YCN

Medicare Advantage

Under this prefix, the member may have Medicare Advantage coverage administered by this BCBS plan. MA claims are subject to CMS regulations in addition to the plan's own policies. Balance billing restrictions apply. Verify the member's specific MA plan details and confirm the correct payer ID for electronic submission.

Traditional Indemnity

This prefix includes traditional indemnity coverage. Indemnity plans are the oldest form of health insurance and offer maximum provider choice with no network restrictions. Members pay a percentage of charges after meeting their deductible. Reimbursement is based on reasonable and customary rates for the service area.

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.
