Coverage under prefix M8P

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.

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.
