Coverage under prefix NNK

HDHP

Under this HDHP prefix, the member's plan has a higher deductible than traditional coverage. This affects patient cost-sharing but does not change how claims are submitted or processed. Use the same payer ID, claims address, and filing procedures listed above. Verify the member's remaining deductible before estimating patient responsibility.

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

This is a traditional indemnity prefix. Unlike managed care plans (HMO, PPO, EPO), indemnity plans do not use provider networks. There are no referral requirements and no restrictions on which providers the member can see. Submit claims to the payer listed above for reimbursement at the plan's allowed rate.
