Present On Admission
POA Help
"Present On Admission" is defined as present at the time the order for inpatient admission occurs — conditions that develop during an outpatient encounter, including emergency department, observation, or outpatient surgery, are considered POA.
  • Q24.8 is considered exempt from POA reporting.
ICD-10-CM Q24.8 is grouped within Diagnostic Related Group(s) (MS-DRG v36.0):
  • 306 Cardiac congenital and valvular disorders with mcc
  • 307 Cardiac congenital and valvular disorders without mcc
