About coding pulmonic valve murmur
The ICD-10-CM code for pulmonic valve murmur is I37.8 (Other nonrheumatic pulmonary valve disorders).
Within I37, choose I37.8 (Other nonrheumatic pulmonary valve disorders) only when documentation doesn't support a more specific option: nonrheumatic pulmonary valve stenosis (I37.0), nonrheumatic pulmonary valve insufficiency (I37.1), nonrheumatic pulmonary valve stenosis with insufficiency (I37.2) and nonrheumatic pulmonary valve disorder, unspecified (I37.9).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
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.
