Coverage under prefix ISX

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.

HMO

Under this HMO prefix, the member's coverage is limited to the plan's provider network. Care is coordinated through a primary care physician. Specialist visits require a referral from the PCP. When billing, confirm that the referring provider and the referral authorization number are included on the claim.

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.
