Nonrheumatic pulmonary valve disorders (I37)

ICD-10 code I37 and its subcategories address nonrheumatic pulmonary valve disorders, which involve problems with the pulmonary valve of the heart not caused by rheumatic fever. These codes help specify diagnoses like narrowed valves, valve leakage, or combined issues affecting the pulmonary valve.

These codes are used to document conditions such as pulmonary valve stenosis (narrowing of the valve), called by terms like "pulmonary stenosis" or "pulmonic valve stenosis," and classified under I37.0. When the valve leaks or doesn't close properly, known as pulmonary valve insufficiency or "pulmonary regurgitation," the appropriate code is I37.1. Cases with both narrowing and leakage fall under I37.2. Other less common or complex valve problems, including valve prolapse, abscesses, thrombosis, calcification, or prosthetic valve failures, are categorized under I37.8. Finally, when the specific nonrheumatic pulmonary valve issue is not detailed, coders use I37.9 for an unspecified disorder. These distinctions help medical coders and healthcare providers accurately capture diagnoses associated with pulmonary valve abnormalities in clinical records and billing.
