POA Exempt
POA Exempt Code
The 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.
| ICD-10 from 2011 - 2016

Q20.4 is a billable ICD code used to specify a diagnosis of double inlet ventricle. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

POA Indicators on CMS form 4010A are as follows:

IndicatorMeaningCMS Will Pay CC/MCC DRG Costs
YDiagnosis was present at time of inpatient admissionYes
NDiagnosis was not present at time of inpatient admissionNo
UDocumentation insufficient to determine if the condition was present at the time of inpatient admission.No
WClinically undetermined. Provider unable to clinically determine whether the condition was present at the time of inpatient admission.Yes

The ICD code Q20 is used to code Congenital heart defect

Congenital heart defect (CHD), also known as a congenital heart anomaly or congenital heart disease, is a problem in the structure of the heart that is present at birth. Signs and symptoms depend on the specific type of problem. Symptoms can vary from none to life-threatening. When present they may include rapid breathing, bluish skin, poor weight gain, and feeling tired. It does not cause chest pain. Most congenital heart problems do not occur with other diseases. Complications that can result from heart defects include heart failure.

MeSH Codes: D006330, D006330, D006330

Common ventricle (exact match)

This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 745.3 was previously used, Q20.4 is the appropriate modern ICD10 code.
