About coding origin of both great vessels from right ventricle
The ICD-10-CM code for origin of both great vessels from right ventricle is Q20.1 (Double outlet right ventricle).
Within Q20 (congenital malformations of cardiac chambers and connections), Q20.1 is specifically for Double outlet right ventricle. Related codes cover common arterial trunk (Q20.0), Double outlet left ventricle (Q20.2), Discordant ventriculoarterial connection (Q20.3), Double inlet ventricle (Q20.4), Discordant atrioventricular connection (Q20.5), Isomerism of atrial appendages (Q20.6), other congenital malformations of cardiac chambers and connections (Q20.8) and congenital malformation of cardiac chambers and connections, unspecified (Q20.9).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 306 (Cardiac Congenital and Valvular Disorders with MCC, relative weight 1.546) and DRG 307 (Cardiac Congenital and Valvular Disorders without MCC, relative weight 0.9148), in MDC 05 (Diseases and Disorders of the Circulatory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
