Coverage under prefix KEI

PPO

PPO (Preferred Provider Organization) plans allow members to visit any healthcare provider without a referral. In-network providers cost less, but out-of-network care is still covered at a reduced rate. When billing for a PPO plan, submit claims directly to the payer listed above. No referral documentation is needed.

Medicaid

Medicaid coverage under this prefix means the member's Medicaid benefits are administered by a BCBS managed care plan. Medicaid managed care claims may have different submission requirements, payer IDs, and timely filing deadlines than commercial claims. Verify the specific Medicaid plan details with the payer.

Medicare Advantage

Medicare Advantage coverage under this prefix means the plan administers Medicare Part A and Part B benefits on behalf of CMS. These claims may have different processing rules than commercial claims, including different prior authorization requirements and appeal timelines. CMS timely filing rules (365 days) typically apply.
