2022 ICD-10-CM Code I43
Cardiomyopathy in diseases classified elsewhere
Valid for Submission
| ICD-10: | I43 |
| Short Description: | Cardiomyopathy in diseases classified elsewhere |
| Long Description: | Cardiomyopathy in diseases classified elsewhere |
Code Classification
I43 is a billable diagnosis code used to specify a medical diagnosis of cardiomyopathy in diseases classified elsewhere. The code I43 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 I43 might also be used to specify conditions or terms like cardiac glycogen phosphorylase kinase deficiency, cardiomyopathy associated with another disorder, cardiomyopathy due to connective tissue disease, cardiomyopathy due to disease caused by severe acute respiratory syndrome coronavirus 2, cardiomyopathy due to storage disease , cardiomyopathy due to viral infection, etc.
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 I43:
Code First
Code FirstCertain 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.
- underlying disease, such as:
- amyloidosis E85
- glycogen storage disease E74.0
- gout M10.0
- thyrotoxicosis E05.0 E05.9
Type 1 Excludes
Type 1 ExcludesA type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
Code Edits
The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10 Code Edits are applicable to this code:
- Manifestation diagnoses - Manifestation codes describe the manifestation of an underlying disease, not the disease itself, and therefore should not be used as a principal diagnosis.
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Cardiac glycogen phosphorylase kinase deficiency
- Cardiomyopathy associated with another disorder
- Cardiomyopathy due to connective tissue disease
- Cardiomyopathy due to disease caused by Severe acute respiratory syndrome coronavirus 2
- Cardiomyopathy due to storage disease
- Cardiomyopathy due to viral infection
- Cardiomyopathy in Duchenne muscular dystrophy
- Cardiomyopathy in Friedreich's ataxia
- Cardiomyopathy in myotonic dystrophy
- Diabetic cardiomyopathy
- Dilated cardiomyopathy associated with connective tissue disorder
- Dilated cardiomyopathy secondary to systemic lupus erythematosus
- Familial cardiomyopathy
- Familial cardiomyopathy
- Familial non-neuropathic amyloidosis
- Familial restrictive cardiomyopathy
- Familial restrictive cardiomyopathy
- Glycogen phosphorylase kinase deficiency
- Glycogen phosphorylase kinase deficiency, autosomal recessive
- Glycogen storage disease with severe cardiomyopathy due to glycogenin deficiency
- Myocardial degeneration
- Primary eosinophilic endomyocardial cardiomyopathy
- Primary eosinophilic endomyocardial restrictive cardiomyopathy
- Primary restrictive cardiomyopathy
- Restrictive cardiomyopathy secondary to familial storage disease
- Restrictive cardiomyopathy with endomyocardial fibrosis
- Transthyretin related familial amyloid cardiomyopathy
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code I43 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 314 | OTHER CIRCULATORY SYSTEM DIAGNOSES WITH MCC | 05 | 2.0834 |
| 315 | OTHER CIRCULATORY SYSTEM DIAGNOSES WITH CC | 05 | 0.9752 |
| 316 | OTHER CIRCULATORY SYSTEM DIAGNOSES WITHOUT CC/MCC | 05 | 0.7495 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert I43 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code I43 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
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.
