Nonrheumatic tricuspid valve disorders (I36)

Nonrheumatic tricuspid valve disorders, classified under ICD-10 code I36, cover various conditions affecting the tricuspid valve of the heart that are not caused by rheumatic fever. These codes are used specifically to identify problems such as valve narrowing, leakage, or other abnormalities unrelated to rheumatic disease.

The ICD-10 code range starting at I36 includes distinct diagnoses like I36.0 for tricuspid valve stenosis (narrowing), sometimes due to tumors or prosthetic valve issues, and I36.1 for tricuspid valve insufficiency or regurgitation, which can be functional or linked to valve prostheses. When both stenosis and insufficiency occur together, I36.2 is used. Other unique tricuspid valve abnormalities such as leaflet prolapse, chordae tendineae defects, thrombosis, or valve leaflet rupture fall under I36.8. If the disorder is nonspecific or not detailed, I36.9 covers these unspecified nonrheumatic tricuspid valve disorders. Using exact codes from the I36 section ensures precise documentation and treatment tracking for nonrheumatic tricuspid valve conditions.

Instructional Notations

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • tricuspid valve disorders of unspecified cause I07
  • tricuspid valve disorders specified as congenital Q22.4 Q22.8 Q22.9
  • tricuspid valve disorders specified as rheumatic I07
  • tricuspid valve disorders with aortic and/or mitral valve involvement I08

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Tricuspid Valve Prolapse

Abnormal protrusion of one or more of the leaflets of TRICUSPID VALVE into the RIGHT ATRIUM during SYSTOLE. This allows the backflow of blood into right atrium leading to TRICUSPID VALVE INSUFFICIENCY; SYSTOLIC MURMURS. Its most common cause is not primary valve abnormality but rather the dilation of the RIGHT VENTRICLE and the tricuspid annulus.
