What Does PR-58 Mean?

With PR (Patient Responsibility), the CARC 58 adjustment for inappropriate or invalid place of service shifts the financial impact to the patient. Before billing the patient, verify that the denial reason is valid. The most common cause is patient chose a higher-cost setting when a lower-cost option was available — if the underlying issue can be corrected, resubmit the claim first to potentially eliminate the patient's liability.

CARC 58 indicates inappropriate or invalid place of service. The payer determined that the service or a portion of it does not meet coverage criteria under the patient's current plan benefits or the applicable coverage rules.

Common scenarios that trigger this adjustment include: payer determined the service could have been appropriately performed in a less expensive setting (e.g., outpatient instead of inpatient); The specific place of service is not approved by the payer for this type of procedure; Payer policy restricts certain services to specific types of facilities. The group code paired with CARC 58 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 Examine the PR-58 denial and any RARC codes to understand why the patient was held responsible.
  2. Gather supporting documentation Collect medical records, authorization documents, or plan benefit details that support coverage.
  3. File an appeal Appeal with clinical documentation if the POS was medically necessary.
  4. Hold patient billing pending appeal Do not bill the patient until the appeal is resolved. If the appeal is denied, then generate a patient statement.
