Coverage under prefix E8Y

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.

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.

Traditional Indemnity

Under this indemnity prefix, the member has fee-for-service coverage. There is no provider network, no referral requirement, and no primary care physician gatekeeper. Claims are processed based on the plan's fee schedule. While less common than managed care plans, indemnity coverage is still offered by some BCBS companies.
