Code Classification

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:

  • BILLABLE CODE - Use I42.0 for Dilated cardiomyopathy
  • BILLABLE CODE - Use I42.1 for Obstructive hypertrophic cardiomyopathy
  • BILLABLE CODE - Use I42.2 for Other hypertrophic cardiomyopathy
  • BILLABLE CODE - Use I42.3 for Endomyocardial (eosinophilic) disease
  • BILLABLE CODE - Use I42.4 for Endocardial fibroelastosis
  • BILLABLE CODE - Use I42.5 for Other restrictive cardiomyopathy
  • BILLABLE CODE - Use I42.6 for Alcoholic cardiomyopathy
  • BILLABLE CODE - Use I42.7 for Cardiomyopathy due to drug and external agent
  • BILLABLE CODE - Use I42.8 for Other cardiomyopathies
  • BILLABLE CODE - Use I42.9 for Cardiomyopathy, unspecified

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:


Includes

Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

Code First

Code 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.

Type 2 Excludes

Type 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.

Clinical Information

Information for Patients


Cardiomyopathy

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 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.
