PR-182: Procedure Modifier Invalid on Date of Service

What Does PR-182 Mean?

With PR (Patient Responsibility), the cost was assigned to the patient due to the invalid modifier. This is atypical — modifier errors are typically the provider's responsibility. Contact the payer to verify the group code assignment.

CARC 182 indicates that a modifier appended to a procedure code on the claim was either expired, not yet effective, or otherwise invalid for the date of service. Modifiers provide additional information about how or where a service was performed, and like procedure codes, they have defined validity periods.

This denial commonly occurs after annual coding updates when modifiers are retired or replaced, when billing systems are not updated with current modifier tables, or when an incorrect modifier is applied due to a data entry error. The resolution is to identify the correct modifier and resubmit the claim.

How to Resolve

1. Verify the group code Contact the payer to confirm PR is the correct assignment for a modifier validity issue.
2. Correct and resubmit Fix the modifier and resubmit the claim.

How to Prevent PR-182

• Keep modifier tables current to prevent charges from being assigned to patients due to coding errors
