Coverage under prefix A4C

Medicare Advantage

Medicare Advantage (MA) coverage means this member receives their Medicare benefits through a private BCBS plan rather than through original Medicare. MA plans may have different payer IDs and claims addresses than the commercial plan. Check with the payer to confirm the correct submission details for Medicare Advantage claims.

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.

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.
