What this denial means, and to whom
The care was for TOMAS TANAKA, a dependent on this policy
The payer withheld $51.44 from the provider for this service. The 835 did not assign any of this adjustment to the patient, so nothing here was reported as the member's responsibility. RARC M51: Missing/incomplete/invalid procedure code(s). Do not treat the denied amount as a patient bill on the strength of this remittance alone. If a bill arrives for it, ask the provider what correction or appeal is under way, and question any balance the remittance does not support.
From: 835 CAS adjustment group codes on this remittance; the 837P patient loop that identifies who was treated.
Limits: This says what the 835 reported, not what was billed. A later remittance, a secondary payer or a correction can each change what the member is asked to pay, and none of that is visible here.
