Diagnosis Code I41
Information for Medical Professionals
The following edits are applicable to this code:
Manifestation diagnoses 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.
Diagnostic Related Groups
The diagnosis code I41 is grouped in the following Diagnostic Related Group(s) (MS-DRG v33.0)
- OTHER CIRCULATORY SYSTEM DIAGNOSES WITH MCC 314
- OTHER CIRCULATORY SYSTEM DIAGNOSES WITH CC 315
- OTHER CIRCULATORY SYSTEM DIAGNOSES WITHOUT CC/MCC 316
Convert to ICD-9 General Equivalence Map
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.
- 422.0 - Ac myocardit in oth dis (approximate) Approximate Flag
The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
- Acute myocarditis associated with another disorder
- Myocarditis due to hypersensitivity state
- Rubella myocarditis
- Subacute myocarditis associated with acquired immunodeficiency syndrome
Index of Diseases and Injuries

- Type 1 Excludes Notes: Type 1 Excludes Notes
A 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 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.
- underlying disease, such as:
- typhus (A75.0-A75.9)
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.
