About I07.2

I07.2 is the ICD-10-CM diagnosis code for rheumatic tricuspid stenosis and insufficiency. It belongs to category I07 (rheumatic tricuspid valve diseases), block I05-I09 (chronic rheumatic heart diseases) and chapter 9 (diseases of the circulatory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within I07 (rheumatic tricuspid valve diseases), I07.2 is specifically for rheumatic tricuspid stenosis and insufficiency. Related codes cover rheumatic tricuspid stenosis (I07.0), rheumatic tricuspid insufficiency (I07.1), 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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 397.0 (diseases of tricuspid valve).
