Not Valid for Submission
I42 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of cardiomyopathy. The code is not specific and is NOT valid for the year 2021 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.
Specific Coding for Cardiomyopathy
Non-specific codes like I42 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for cardiomyopathy:
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code I42:
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
Code FirstCode First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
- pre-existing cardiomyopathy complicating pregnancy and puerperium O99.4
Type 2 ExcludesType 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
- CARDIOMYOPATHY ALCOHOLIC-. disease of cardiac muscle resulting from chronic excessive alcohol consumption. myocardial damage can be caused by: 1 a toxic effect of alcohol; 2 malnutrition in alcoholics such as thiamine deficiency; or 3 toxic effect of additives in alcoholic beverages such as cobalt. this disease is usually manifested by dyspnea and palpitations with cardiomegaly and congestive heart failure heart failure.
- 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.
- CHAGAS CARDIOMYOPATHY-. a disease of the cardiac muscle developed subsequent to the initial protozoan infection by trypanosoma cruzi. after infection less than 10% develop acute illness such as myocarditis mostly in children. the disease then enters a latent phase without clinical symptoms until about 20 years later. myocardial symptoms of advanced chagas disease include conduction defects heart block and cardiomegaly.
- 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.
- MUSCULAR DYSTROPHY DUCHENNE-. an x linked recessive muscle disease caused by an inability to synthesize dystrophin which is involved with maintaining the integrity of the sarcolemma. muscle fibers undergo a process that features degeneration and regeneration. clinical manifestations include proximal weakness in the first few years of life pseudohypertrophy cardiomyopathy see myocardial diseases and an increased incidence of impaired mentation. becker muscular dystrophy is a closely related condition featuring a later onset of disease usually adolescence and a slowly progressive course. adams et al. principles of neurology 6th ed p1415
- 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.
- TAKOTSUBO CARDIOMYOPATHY-. a transient left ventricular apical dysfunction or ballooning accompanied by electrocardiographic ecg t wave inversions. this abnormality is associated with high levels of catecholamines either administered or endogenously secreted from a tumor or during extreme stress.
- 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.
Information for Patients
Also called: Dilated cardiomyopathy, Hypertrophic cardiomyopathy, Myocardiopathy, Restrictive cardiomyopathy
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
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.
