Coverage under prefix MKL

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.

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.

POS

This prefix is linked to a POS plan. Point of Service coverage gives members a choice at the time of service: use the HMO-style in-network benefit with a referral for lower costs, or access out-of-network providers at reduced coverage levels. The billing approach depends on which option the member chooses.
