Valid for Submission
I42.8 is a billable diagnosis code used to specify a medical diagnosis of other cardiomyopathies. The code I42.8 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code I42.8 might also be used to specify conditions or terms like arrhythmogenic right ventricular dysplasia, arrhythmogenic right ventricular dysplasia, autosomal recessive familial wooly hair, cardiomyopathy, congenital wooly hair , disorder of myocardium associated with rejection of cardiac transplant, etc.
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code I42.8 are found in the index:
- - Cardiomyopathy (familial) (idiopathic) - I42.9
- - Dysplasia - See Also: Anomaly;
- - Myocardiopathy (congestive) (constrictive) (familial) (hypertrophic nonobstructive) (idiopathic) (infiltrative) (obstructive) (primary) (restrictive) (sporadic) - See Also: Cardiomyopathy; - I42.9
- - obscure (African) - I42.8
- - South African cardiomyopathy syndrome - I42.8

- TMEM70 related mitochondrial encephalo-cardio-myopathy
- Valvular cardiomyopathy
- Ventricular myocardial noncompaction cardiomyopathy
- CARDIOMYOPATHY DILATED-. a form of cardiac muscle disease that is characterized by ventricular dilation ventricular dysfunction and heart failure. risk factors include smoking; alcohol drinking; hypertension; infection; pregnancy; and mutations in the lmna gene encoding lamin type a a nuclear lamina protein.
- CARDIOMYOPATHY HYPERTROPHIC-. a form of cardiac muscle disease characterized by left and/or right ventricular hypertrophy hypertrophy left ventricular; hypertrophy right ventricular frequent asymmetrical involvement of the heart septum and normal or reduced left ventricular volume. risk factors include hypertension; aortic stenosis; and gene mutation; familial hypertrophic cardiomyopathy.
- CARDIOMYOPATHY RESTRICTIVE-. a form of cardiac muscle disease in which the ventricular walls are excessively rigid impeding ventricular filling. it is marked by reduced diastolic volume of either or both ventricles but normal or nearly normal systolic function. it may be idiopathic or associated with other diseases endomyocardial fibrosis or amyloidosis causing interstitial fibrosis.
- CARDIOMYOPATHIES-. a group of diseases in which the dominant feature is the involvement of the cardiac muscle itself. cardiomyopathies are classified according to their predominant pathophysiological features dilated cardiomyopathy; hypertrophic cardiomyopathy; restrictive cardiomyopathy or their etiological/pathological factors cardiomyopathy alcoholic; endocardial fibroelastosis.
- CARDIOMYOPATHY HYPERTROPHIC FAMILIAL-. an autosomal dominant inherited form of hypertrophic cardiomyopathy. it results from any of more than 50 mutations involving genes encoding contractile proteins such as ventricular myosins; cardiac troponin t; alpha tropomyosin.
- GLYCOGEN STORAGE DISEASE TYPE IIB-. an x linked dominant multisystem disorder resulting in cardiomyopathy myopathy and intellectual disability. it is caused by mutation in the gene encoding lysosomal associated membrane protein 2.
- DIABETIC CARDIOMYOPATHIES-. diabetes complications in which ventricular remodeling in the absence of coronary atherosclerosis and hypertension results in cardiac dysfunctions typically left ventricular dysfunction. the changes also result in myocardial hypertrophy myocardial necrosis and fibrosis and collagen deposition due to impaired glucose tolerance.

Convert I42.8 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code I42.8 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Cardiomyopathy is the name for diseases of the heart muscle. These diseases enlarge your heart muscle or make it thicker and more rigid than normal. In rare cases, scar tissue replaces the muscle tissue.
Some people live long, healthy lives with cardiomyopathy. Some people don't even realize they have it. In others, however, it can make the heart less able to pump blood through the body. This can cause serious complications, including
- Heart failure
- Abnormal heart rhythms
- Heart valve problems
- Sudden cardiac arrest (SCA)
Heart attacks, high blood pressure, infections, and other diseases can all cause cardiomyopathy. Some types of cardiomyopathy run in families. In many people, however, the cause is unknown. Treatment might involve medicines, surgery, other medical procedures, and lifestyle changes.
