M99 Remark Code - Missing/Invalid Product Number
The M99 remark code indicates that there is a missing, incomplete, or invalid Universal Product Number (UPN) or Serial Number associated with the billed item. This remark supplements a Claim Adjustment Reason Code which identifies the primary reason for the adjustment, clarifying that the issue is specifically related to product identification details.
How It Relates to the Denial
The M99 remark code typically accompanies adjustment reason codes that deal with billing errors or insufficient information related to the product being billed. Together, they signal that the claim cannot be processed due to identification issues with the product or device in question.
Common Scenarios
1A provider submits a claim for a medical device that requires a Universal Product Number, but the claim is returned with a denial indicating the product number is missing.
→ In this case, the M99 remark code is pointing out that the claim cannot be processed because the required UPN is either not provided or invalid. The payer expects the provider to supply the correct product identification.
2A pharmacy bills for a medication that should have a Serial Number, but the remittance shows an adjustment for insufficient information.
→ Here, the M99 remark code signifies that the adjustment is due to the missing or invalid Serial Number for the billed medication. The payer is indicating that this information needs to be clarified or corrected.
3A surgical facility submits a claim for a piece of equipment used during a procedure, but the remittance indicates an adjustment due to an incomplete product number.
→ The M99 remark code suggests that the adjustment is due to the lack of a complete Universal Product Number for the equipment billed. The payer is indicating that the claim cannot be processed without this detail.
What to Do
