• Woodmen/Assured Life’s Medicare Supplement administrative office will not process Medicare payment estimates where Medicare has not made a final determination on the claim.
• Only the “official” Medicare remittance advice or HIPAA 835 ERA should be used for supplemental billing purposes when filing a claim – Medicare’s predetermination of benefits will not be accepted.
