What Does PR-11 Mean?

With PR (Patient Responsibility), the CARC 11 adjustment for diagnosis inconsistent with procedure shifts the financial impact to the patient. Before billing the patient, verify that the denial reason is valid. The most common cause is diagnosis-procedure inconsistency results in reduced coverage with balance to patient — if the underlying issue can be corrected, resubmit the claim first to potentially eliminate the patient's liability.

CARC 11 appears on a remittance when the payer identifies an issue related to diagnosis inconsistent with procedure. This is a technical billing or coding problem that must be corrected before the claim can be processed for payment. The denial indicates the claim data did not meet the payer's adjudication requirements.

Common scenarios that trigger this adjustment include: the ICD-10 code does not provide medical necessity justification for the CPT code billed; Coder selected an ICD-10 code that does not match the clinical reason for the procedure; The diagnosis pointer on the claim line links to an unrelated diagnosis code. The group code paired with CARC 11 determines who bears the financial responsibility — CO places it on the provider as a contractual obligation, PR shifts it to the patient, OA indicates a coordination of benefits or other payer adjustment.

How to Resolve

  1. Review the denial reason Examine the remittance for CARC 11 and any accompanying RARC codes to understand the specific issue behind the PR adjustment.
  2. Determine if the issue is correctable Check whether the underlying problem (coverage reduced due to diagnosis mismatch) can be fixed. If so, correct and resubmit before billing the patient.
  3. Correct and resubmit if applicable If the denial is due to an error that can be corrected, fix the issue and resubmit the claim to potentially eliminate the patient's liability.
  4. Appeal if the PR designation is incorrect Appeal if the diagnosis-procedure combination is correct and the patient responsibility amount is incorrect.
  5. Bill the patient if the determination stands If the PR adjustment is confirmed correct and no correction or appeal is viable, generate a patient statement and follow standard collection procedures.
