Definition · Codes and claim data
A present on admission indicator on an inpatient claim says whether a diagnosis was present when the patient was admitted. CMS uses it so a hospital is not paid extra for a condition that developed after admission in specified cases. It is not part of the ICD-10-CM code itself. Use the ICD-10 code lookup.

The indicator is reported with the diagnosis code. The code page on this site shows the CDC description. It does not show the indicator, because the indicator is a claim fact.
