Coverage under prefix B2Q

POS

Under this POS prefix, the member can access care both in-network and out-of-network, with cost-sharing that varies based on how the care is accessed. In-network care coordinated through the member's PCP has the lowest out-of-pocket cost. Include referral documentation when billing at the in-network benefit level.

Traditional Indemnity

Traditional indemnity coverage means the member has fee-for-service insurance with no network limitations. Any licensed provider can be seen without referrals. Claims are reimbursed based on usual, customary, and reasonable (UCR) charges. The member typically pays a deductible and a percentage of allowed charges.

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.
