IPCCC ICD-11 Congenital Heart Atlas

You are here: Communication between left ventricle and right atrium Congenital anomaly of an atrioventricular valve or atrioventricular septum Structural developmental anomaly of heart or great vessels

IPCCC Term Communication between left ventricle and right atrium
IPCCC Code 07.14.02
ICD-11 MMS LA87.Y
ICD-11 Code 1370033158

Definition

A deficiency of the atrioventricular component of the membranous septum permitting shunting of blood from the left ventricle to the right atrium.

Synonyms/Abbreviations

Gerbode defect

STS-EACTS-derived IPCCC term

VSD, Type: Gerbode type (Left ventricle to right atrial communication)

EPCC-derived IPCCC term

Communication between left ventricle and right atrium (Gerbode defect)

ICD-11 MMS code or crossmap

LA87.Y*: This Foundation term is not in ICD-11 MMS. If using MMS to code, crossmap to "Other specified congenital anomaly of an atrioventricular valve or atrioventricular septum" with code LA87.Y

ICD-10 MMS code or crossmap

Q21.0**: This term is not in ICD-10. If coding using ICD-10, use the higher order term “Ventricular septal defect” with code Q21.0

Parent

Congenital anomaly of an atrioventricular valve or atrioventricular septum

Coding Notes

This is an isolated absence of the atrioventricular septum without other components that may be commonly seen in association with spectrum of disorders associated with atrioventricular septal defects such as a common atrioventricular valve or interatrial or interventricular communications. The Gerbode defect may be confused with ventricular septal defects where a deficiency of tricuspid valvar tissue permits ventriculo-atrial shunting subsequent to initial interventricular shunting (left ventricle to right ventricle to right atrium).
