Coverage under prefix M3N

PPO

This prefix is associated with a PPO plan. Preferred Provider Organization coverage gives members flexibility to see specialists without referrals and to use out-of-network providers at higher cost-sharing. Claims can be submitted for both in-network and out-of-network services, though reimbursement rates differ.

Traditional Indemnity

Traditional indemnity coverage under this prefix is a fee-for-service plan. Members can see any provider without network restrictions or referral requirements. The plan reimburses a set percentage of usual and customary charges. Claims are submitted directly to the payer listed above.

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.
