I40. 0 converts approximately to one of the following ICD-9-CM codes: 422.91 - Idiopathic myocarditis.
B33. 22 - Viral myocarditis. ICD-10-CM.
Myocarditis is inflammation of the heart muscle (myocardium). The inflammation can reduce the heart's ability to pump blood. Myocarditis can cause chest pain, shortness of breath, and rapid or irregular heart rhythms (arrhythmias). Infection with a virus is one cause of myocarditis.
A rare condition in which the heart muscle becomes thick and inflamed and may also become weak. Myocarditis is usually caused by a viral infection, but it may also be caused by bacterial, parasitic, or fungal infections; autoimmune disorders; or being exposed to radiation or certain chemicals or drugs.
Acute myocarditis is inflammation of the myocardium. It is typically seen in infants and teenagers but can occur at any age. It most commonly results from a viral illness; however, it can also be due to non-infectious etiologies.
I40. 9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
Myocarditis can also lead to other complications, including atrial fibrillation, an irregular heartbeat that can cause serious problems, and blood clots that may result in a stroke.
The case highlights that COVID-19-associated myocarditis can present as new atrial fibrillation (AF) and heart failure without the classic COVID-19-associated symptoms.
Heart arrhythmias can occur during acute myocarditis. These arrhythmias can be of almost any type, including both the bradycardias (slow heart rhythms) and tachycardias (rapid heart rhythms), such as atrial fibrillation and ventricular tachycardia.
Myocarditis Causes Myocarditis is rare, but when it occurs, it is most commonly caused by an infection in the body. Infections from viruses (most common, including those that cause the common cold, influenza or COVID-19), bacteria, fungus or parasites can lead to myocardial inflammation.
To diagnose myocarditis, a health care provider will typically examine you and listen to your heart with a stethoscope. Blood and imaging tests may be done to check your heart health. Imaging tests can help confirm myocarditis and determine its severity.
Myocarditis is inflammation of the heart muscle, and pericarditis is inflammation of the outer lining of the heart. In both cases, the body's immune system causes inflammation in response to an infection or some other trigger. Learn more about myocarditis and pericarditis.
Viral cardiomyopathy is defined as viral persistence in a dilated heart. It may be accompanied by myocardial inflammation and then termed inflammatory viral cardiomyopathy (or viral myocarditis with cardiomegaly).
Selected treatments for COVID-19-associated myocarditis were variable, but the most common approach was supportive treatment alone (43.1%). Supportive therapy included intravenous/oral hydration, beta-blockers, or diuretics.
I09. 0 - Rheumatic myocarditis | ICD-10-CM.
ICD-10 code I21. 9 for Acute myocardial infarction, unspecified is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
Inclusion Terms are a list of concepts for which a specific code is used. The list of Inclusion Terms is useful for determining the correct code in some cases, but the list is not necessarily exhaustive.

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 I40.1 and a single ICD9 code, 422.91 is an approximate match for comparison and conversion purposes.
422.91 is a legacy non-billable code used to specify a medical diagnosis of idiopathic myocarditis. This code was replaced on September 30, 2015 by its ICD-10 equivalent.
References found for the code 422.91 in the Index of Diseases and Injuries:
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.
General Equivalence Map Definitions The ICD-9 and ICD-10 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.
