What Does PR-A6 Mean?

When paired with Group Code PR, the patient bears financial responsibility because the prior hospitalization requirement was not met. This may occur for elective admissions without the required qualifying stay. Appeal with documentation if the requirement was actually met but not reflected on the claim.

CARC A6 indicates the payer denied the claim because a required prior hospitalization or 30-day transfer condition was not met. Certain services — most commonly skilled nursing facility (SNF) admissions under Medicare — require the patient to have had a qualifying inpatient hospital stay within a specified period (typically 30 days) before the current admission or service.

The denial may occur because no qualifying prior hospitalization was found in the payer's records, the prior stay was outside the required time window, the patient was not formally transferred from a qualifying facility, documentation of the qualifying stay was not included with the claim, or incorrect admission dates prevented the system from recognizing the qualifying stay.

The most common resolution path is locating documentation of the qualifying prior hospitalization and submitting it with an appeal. If the prior stay exists but was at a different facility, obtaining records from that facility may be necessary.

Common Causes

Cause Frequency
Patient did not meet admission criteria The patient's condition did not meet the prior hospitalization requirement and the patient bears financial responsibility Common
Elective admission without prior qualifying stay The patient was admitted electively without the required prior hospitalization within the coverage window Common

How to Resolve

  1. Verify the prior hospitalization requirement Determine whether the qualifying stay actually occurred.
  2. Appeal with documentation if met If the qualifying stay occurred, appeal with discharge summary and admission dates to remove patient liability.
  3. Inform the patient if not met If the requirement was genuinely not satisfied, inform the patient of their financial responsibility.
Appeal Guide
