Coverage under prefix NNW

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.

PPO

Under this PPO prefix, members are covered for both in-network and out-of-network care. The plan pays a higher percentage of allowed charges when members use participating providers. No gatekeeper or primary care referral is required. Verify the member's specific benefits for cost-sharing details.

HMO

HMO (Health Maintenance Organization) plans require members to choose a primary care physician (PCP) and obtain referrals before seeing specialists. Out-of-network services are generally not covered except in emergencies. Claims must be submitted to the payer listed above and should include referral authorization when applicable.
