About coding tricuspid valve stenosis
The ICD-10-CM code for tricuspid valve stenosis is I07.0 (Rheumatic tricuspid stenosis). The official index lists 9 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on I07.0.
Within I07 (rheumatic tricuspid valve diseases), I07.0 is specifically for rheumatic tricuspid stenosis. Related codes cover rheumatic tricuspid insufficiency (I07.1), rheumatic tricuspid stenosis and insufficiency (I07.2), other rheumatic tricuspid valve diseases (I07.8) and rheumatic tricuspid valve disease, unspecified (I07.9).
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.
