Coverage under prefix WKW

PPO

This is a Preferred Provider Organization (PPO) prefix. PPO plans are the most common BCBS plan type. Members have the freedom to self-refer to specialists. Claims for in-network services are typically processed faster and reimbursed at higher rates than out-of-network claims.

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.

Medicaid

Medicaid managed care under this BCBS prefix means the state has contracted with this plan to administer Medicaid benefits. Balance billing Medicaid members is prohibited. Timely filing requirements may follow state Medicaid rules rather than the plan's commercial deadlines. Contact the plan to confirm submission requirements.
