Coverage under prefix GNO

Medicare Advantage

This prefix includes Medicare Advantage coverage. MA plans follow CMS guidelines for timely filing (365 days from date of service), which may differ from the commercial plan's deadline. The payer ID for Medicare Advantage claims may differ from the standard commercial payer ID. Verify before submitting.

PPO

PPO coverage under this prefix means the member can access any provider. In-network providers have negotiated rates with the plan, while out-of-network providers are reimbursed based on usual and customary charges. Prior authorization is generally not required for routine services but may be needed for high-cost procedures.

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.
