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.
  • I25.2 is considered exempt from POA reporting.
ICD-10-CM I25.2 is grouped within Diagnostic Related Group(s) (MS-DRG v37.0):
  • 302 Atherosclerosis with mcc
  • 303 Atherosclerosis without mcc
