Coverage under prefix W4K

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.

HMO

Under this HMO prefix, the member's coverage is limited to the plan's provider network. Care is coordinated through a primary care physician. Specialist visits require a referral from the PCP. When billing, confirm that the referring provider and the referral authorization number are included on the claim.

POS

POS (Point of Service) plans combine features of HMO and PPO coverage. Members choose a primary care physician and can get referrals to see in-network specialists at lower cost, or self-refer to out-of-network providers at higher cost. Claims should include referral information when the member uses the in-network benefit level.
