Coverage under prefix A9I

EPO

This is an Exclusive Provider Organization (EPO) prefix. EPO plans do not cover out-of-network care except in genuine emergencies. Members can see any in-network specialist without a referral from their primary care physician. Claims for out-of-network non-emergency services will be denied.

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.

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.
