In simple words: This code represents a heart condition related to rheumatic fever that is not specifically described by other codes.

This code encompasses rheumatic heart diseases that are not otherwise specified, such as rheumatic disease of the pulmonary valve, and other unspecified rheumatic heart diseases.

Example 1: A patient with a history of rheumatic fever presents with symptoms of pulmonary valve stenosis, such as shortness of breath and chest pain, and echocardiography confirms the diagnosis of rheumatic pulmonary valve disease., A patient with a past diagnosis of rheumatic fever experiences fatigue and palpitations. After a thorough examination and diagnostic testing, the physician determines that the patient has rheumatic heart disease affecting unspecified structures of the heart, not classified under other I09 categories., A patient with known rheumatic heart disease develops symptoms like shortness of breath and swelling in the legs. After an echocardiogram and physical examination, the doctor diagnoses the patient with rheumatic heart disease, impacting an area not explicitly defined by existing I09 codes.

Documentation should include evidence of a prior rheumatic fever episode, clinical findings related to the current heart condition, and results of diagnostic tests such as echocardiography or electrocardiography that confirm the specific rheumatic heart disease.
