ICD-10-CM Code I43
Cardiomyopathy in diseases classified elsewhere
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.Manifestation Code
Certain ICD-10-CM codes identify an underlying condition known as an etiology code. Conditions that arise as a result of an underlying condition (etiology), are referred to as Manifestations. In ICD-10-CM, etiology codes must be coded first, followed by the manifestation codes. When a condition requires etiology and manifestation codes, there is a "use additional code" note following the etiology code and a "code first" note following the manifestation code.I43 is a billable ICD code used to specify a diagnosis of cardiomyopathy in diseases classified elsewhere. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code I43 is used to code Cardiomyopathy
Cardiomyopathy (literally "heart muscle disease") is the measurable deterioration for any reason of the ability of the myocardium (the heart muscle) to contract, usually leading to heart failure. Common symptoms include dyspnea (breathlessness) and peripheral edema (swelling of the legs). Those with cardiomyopathy are often at risk of dangerous forms of irregular heart rate and sudden cardiac death. The most common form of cardiomyopathy is dilated cardiomyopathy. Although the term "cardiomyopathy" could theoretically apply to almost any disease affecting the heart, it is usually reserved for "severe myocardial disease leading to heart failure." Cardiomyopathy and myocarditis resulted in 443,000 deaths in 2013, up from 294,000 in 1990.

- codeFirst:
- Underlying disease, such as:
- Amyloidosis See code E85.-

Code Type-1 Excludes:
Type-1 Excludes
Type-1 Excludes mean the conditions excluded are mutually exclusive and should never be coded together. Excludes 1 means "do not code here." - Cardiomyopathy (in):
- Coxsackie (virus) - instead, use code B33.24
- Diphtheria - instead, use code A36.81
- Sarcoidosis - instead, use code D86.85
- Tuberculosis - instead, use code A18.84

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)
This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code I43 and a single ICD9 code, 425.8 is an approximate match for comparison and conversion purposes.
