Other hypertrophic cardiomyopathy
ICD-10 I42.2 is a billable code used to indicate a diagnosis of other hypertrophic cardiomyopathy.
I42.2 refers to 'Other hypertrophic cardiomyopathy,' a condition characterized by abnormal thickening of the heart muscle, particularly affecting the interventricular septum. This condition can lead to obstructive or non-obstructive forms of hypertrophic cardiomyopathy, resulting in impaired cardiac function. Clinically, patients may present with symptoms such as dyspnea, chest pain, palpitations, and syncope. The anatomy involved includes the left ventricle, which may become stiff and less able to relax, leading to diastolic dysfunction. Disease progression can vary widely; some patients remain asymptomatic, while others may develop severe heart failure or arrhythmias. Diagnostic considerations include echocardiography, which is essential for visualizing the hypertrophy, and genetic testing may be warranted in familial cases. Other imaging modalities, such as MRI, can provide additional insights into myocardial structure and function.

I42.2 encompasses various forms of hypertrophic cardiomyopathy that do not fall under specific genetic or other defined categories. This includes cases where the cause is unknown or multifactorial, and it may also include secondary hypertrophy due to other conditions.
I42.2 should be used when the hypertrophic cardiomyopathy does not fit into the more specific categories such as I42.0 (Hypertrophic cardiomyopathy due to genetic conditions) or I42.1 (Hypertrophic cardiomyopathy due to other conditions). Proper clinical evaluation is essential for accurate coding.
Documentation should include a comprehensive clinical assessment, echocardiographic findings, any relevant genetic testing results, and a detailed history of symptoms. Clear notes on the patient's functional status and any treatments attempted are also crucial.
