when a history of structural abnormalities are captured. If the patient has a history of a structural abnormality, sequence 4545 seeks to capture the type or types. This is a multi-select field, therefore if the patient has had multiple structural abnormalities from birth to the current procedure, all would be captured. If the patient has a history of a left ventricular aneurysm, left ventricular non-compaction syndrome that puts the patient at risk for sudden cardiac arrest, and Takotsubo's cardiomyopathy, just to name a few, then left ventricular structural abnormality associated with risk for sudden cardiac arrest would be selected. If the patient has a history of hypertrophic cardiomyopathy with high-risk features, of which include ventricular fibrillation, cardiac arrest, spontaneous sustained ventricular tachycardia, a family history of premature sudden death, unexplained syncope, left ventricular syncope, left ventricular thickness of 30 millimeters or thicker, abnormal exercise blood pressure, non-sustained spontaneous ventricular tachycardia, atrial fibrillation, myocardial ischemia, left ventricular outflow obstruction, high-risk mutation, or intense competitive physical exertion, then hypertrophic cardiomyopathy with high-risk features would be selected. If a high-risk feature is not present in the documentation, then hypertrophic cardiomyopathy with high-risk features would not be selected. Infiltrated structural abnormalities would be captured if there is documentation of amyloidosis, sarcoidosis, giant cell myocarditis, or Chagas disease. This list is not all inclusive of all potential infiltrative structural abnormalities. Therefore, please work with your clinician to assure the appropriate coding of other infiltrative abnormalities. While the selection of arrhythmogenic ventricular cardiomyopathy references the right ventricle, both right and left arrhythmogenic ventricular cardiomyopathies are captured when a diagnosis is made. Congenital heart disease associated with sudden cardiac arrest can include tetralogy of fallot, ventricular septal defects, Epstein abnormality, transposition of great vessels, a patent foramen ovale, atrial septal defect, and a common ventricle. This list is not all inclusive of all potential congenital heart diseases associated with sudden cardiac arrest structural abnormalities. Therefore, please work with your clinician to assure the appropriate coding of others.
