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 v37.0):

306 Cardiac congenital and valvular disorders with mcc
307 Cardiac congenital and valvular disorders without mcc
