Present on Admission Exempt ICD-10 Codes - Trisomy 18 and Trisomy 13 (Q91)

The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific ICD-10 diagnosis codes that are exempt from the POA reporting requirement.
