Coverage under prefix GPK

Traditional Indemnity

This prefix includes traditional indemnity coverage. Indemnity plans are the oldest form of health insurance and offer maximum provider choice with no network restrictions. Members pay a percentage of charges after meeting their deductible. Reimbursement is based on reasonable and customary rates for the service area.

EPO

Under this EPO prefix, the member has no out-of-network coverage for routine care. However, unlike HMO plans, no referral is needed to see a specialist within the network. When billing, confirm the provider's network participation status with the plan before submitting the claim.

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.
