In simple words: Narrowing of the pulmonary valve that is not caused by rheumatic fever.

Nonrheumatic pulmonary valve stenosis.

Example 1: A 45-year-old patient presents with shortness of breath and fatigue. After diagnostic tests, including an echocardiogram, they are diagnosed with nonrheumatic pulmonary valve stenosis (I37.0)., A pediatric patient with a history of heart murmur is found to have nonrheumatic pulmonary valve stenosis (I37.0) during a routine check-up., An adult patient undergoing a cardiac catheterization is incidentally found to have mild nonrheumatic pulmonary valve stenosis (I37.0).

Documentation should include the type of disorder (stenosis), the valve affected (pulmonary valve), temporal parameters (acute, chronic, etc.), and any causal factors if known. Imaging studies such as echocardiograms are crucial for confirming the diagnosis and assessing the severity.

** This code specifically refers to nonrheumatic pulmonary valve stenosis. It is important to differentiate this from congenital or rheumatic causes. Conditions originating in the perinatal period, certain infectious and parasitic diseases, complications of pregnancy, childbirth and the puerperium, congenital malformations, deformations, chromosomal abnormalities, endocrine, nutritional and metabolic diseases, injury, poisoning and certain other consequences of external causes, neoplasms, symptoms, signs and abnormal clinical and laboratory findings, and systemic connective tissue disorders are excluded.
