POA Exempt CodeThe Center for Medicare & Medicaid Services (CMS) requires medical coders to indicate whether or not a condition was present at the time of admission, in order to properly assign MS-DRG codes. This "Present On Admission" (POA) indicator is recorded on CMS form 4010A.
Q23.3 is a billable ICD code used to specify a diagnosis of congenital mitral insufficiency. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
POA Indicators on CMS form 4010A are as follows:
|Indicator||Meaning||CMS Will Pay CC/MCC DRG Costs|
|Y||Diagnosis was present at time of inpatient admission||Yes|
|N||Diagnosis was not present at time of inpatient admission||No|
|U||Documentation insufficient to determine if the condition was present at the time of inpatient admission.||No|
|W||Clinically undetermined. Provider unable to clinically determine whether the condition was present at the time of inpatient admission.||Yes|

The ICD code Q233 is used to code Mitral insufficiency
Mitral insufficiency (MI), mitral regurgitation or mitral incompetence is a disorder of the heart in which the mitral valve does not close properly when the heart pumps out blood. It is the abnormal leaking of blood backwards from the left ventricle, through the mitral valve, into the left atrium, when the left ventricle contracts, i.e. there is regurgitation of blood back into the left atrium. MI is the most common form of valvular heart disease.
