Coverage under prefix KTO

EPO

EPO (Exclusive Provider Organization) plans require members to use in-network providers, similar to an HMO. The key difference is that referrals are usually not required to see a specialist. Out-of-network care is not covered except in emergency situations. Submit claims to the payer listed above.

HDHP

Under this HDHP prefix, the member's plan has a higher deductible than traditional coverage. This affects patient cost-sharing but does not change how claims are submitted or processed. Use the same payer ID, claims address, and filing procedures listed above. Verify the member's remaining deductible before estimating patient responsibility.

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.
