Complete Medicare Denial Codes List - Updated

 

Medicare denial codes provide or describe the standard information to a patient or provider by an insurances about why a claim was denied. This is the standard format followed by all insurance companies for relieving the burden on the medical providers. MACs (Medicare Administrative Contractors) use appropriate group, claim adjustment reason, or remittance advice remark codes to communicate that why a claim or charges are not covered by Medicare and who is financially responsible for the charges.

A group code is a code identifying the general category of payment adjustment. Valid group codes for use on Medicare remittance advice are:

CO – Contractual Obligations: This group code is used when a contractual agreement between the payer and payee, or a regulatory requirement, resulted in an adjustment. These adjustments are considered a write off for the provider and are not billed to the patient in most of the cases.
OA – Other Adjustments: This group code is used when no other group code applies to the adjustment.
PR – Patient Responsibility: This group code is used when the adjustment represents an amount that may be billed to the patient or insured. This group would typically be used for deductible and co-pay adjustments.
