ICD-10 Code I07.9 – Rheumatic tricuspid valve disease, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I07.9 – Rheumatic tricuspid valve disease, unspecified
What it is
This code identifies rheumatic involvement of the tricuspid valve when the record does not specify the exact type of lesion. Use it for valve damage linked to rheumatic heart disease, with unspecified tricuspid valve findings.
Clinical signs
Clinical features vary; refer to documentation. Findings may include a tricuspid murmur, right-sided heart strain, or signs of tricuspid valve dysfunction on echocardiography.
When to use this code
Use I07.9 when the provider documents rheumatic tricuspid valve disease but does not name stenosis, insufficiency, or another specific lesion. It also fits when the diagnosis is confirmed, yet the chart only states “unspecified” tricuspid valve involvement. Check documentation if the record suggests a different valvular disorder.
Do not use for
Do not use this code for nonrheumatic tricuspid valve disorders or for a more specific rheumatic tricuspid diagnosis that is documented elsewhere. If the note only describes a murmur or suspected disease, check documentation.
Coding tip
Code the most specific rheumatic tricuspid valve term documented; if the lesion type is missing, I07.9 is appropriate.
