ICD Code I42.1

ICD code I42.1 is obstructive hypertrophic cardiomyopathy, a condition where the heart muscle becomes abnormally thick and obstructs blood flow, making it harder for the heart to pump blood effectively.

1. Presence of left ventricular hypertrophy, particularly involving the interventricular septum

2. Evidence of dynamic left ventricular outflow tract obstruction, either at rest or with provocation

3. Symptoms such as exertional dyspnea, chest pain, palpitations, or syncope

4. Echocardiographic findings of asymmetric septal hypertrophy and systolic anterior motion of the mitral valve

5. Absence of secondary causes of hypertrophy, such as hypertension or aortic stenosis

6. Family history suggestive of inherited cardiomyopathy

7. Electrocardiogram (ECG) abnormalities consistent with left ventricular hypertrophy or repolarization changes

Relevant CPT codes that may be used to treat ICD code I42.1 include:

- 93451: Right heart catheterization

- 93452: Left heart catheterization

- 93458: Coronary angiography with left heart catheterization

- 92986: Percutaneous balloon valvuloplasty

- 92960: Cardioversion, elective, external

- 33249: Insertion or replacement of permanent implantable defibrillator system

- 33208: Insertion of new or replacement of permanent pacemaker with transvenous electrodes; atrial and ventricular

- 33533–33536: Coronary artery bypass grafting (CABG)

- 33418: Transcatheter mitral valve repair

- 33430: Surgical repair of ventricular septal defect

These CPT codes are commonly associated with the management and treatment of I42.1.
