Other congenital malformations of cardiac chambers and connections

BILLABLE

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

Q20.8 is a billable ICD code used to specify a diagnosis of other congenital malformations of cardiac chambers and connections. 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
1Exempt from POA reportingNo


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.

Specialty: Cardiology
MeSH Codes: D006330, D006330, D006330
ICD 9 Codes: 745, 746, 747

The normal structure of the heart (left) in comparison to two common locations for a ventricular septal defect (right), the most common form of congenital heart defect.

This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code Q20.8 and a single ICD9 code, 745.8 is an approximate match for comparison and conversion purposes.
