|External ICD10 Documentation|
This diagnosis is a part of ICD10 collection.
Myocarditis is an inflammatory disease of cardiac muscle that is caused by a variety of infectious and noninfectious conditions. We differentiate between the following in this database:
- Myocarditis/carditis, acute infective
- Myocarditis, chronic
- Myocarditis, acute noninfective
- Myocarditis, acute NOS
Acute myocarditis has been defined as a condition with symptoms (most commonly of heart failure) developing over three months or less, while chronic myocarditis has been defined as developing over greater than three months.
The relationship between myocarditis and cardiomyopathies is complex. Myocarditis can (but may not) result in a cardiomyopathy, or it may resolve completely. In many people with cardiomyopathy, there may have been a myocarditis in the past, but the inflammatory component is gone by the time the cardiomyopathy is diagnosed.
Diagnostic criteria: New 12-lead ECG and/or Holter and/or stress testing abnormalities
- Elevated troponin T or troponin I.
- Functional and structural abnormalities on cardiac imaging (echocardiogram, angiogram, or CMR)
- Tissue characterization by CMR (cardiovascular magnetic resonance) or EMB (endomyocardial biopsy)

Possible Simultaneous Presence of Multiple Different Types of Infection in a Single Site
- This refers to the situation where there may be simultaneous infection with multiple types of organisms -- e.g. 2 of bacteria, virus, fungus. While a classic example is a proven viral pneumonia (e.g. influenza) with a suspected/possible bacterial pneumonia superimposed, this kind of thing can occur in places other than the lungs, e.g. meningitis.
- The "signature" of this is typically the patient being treated simultaneously with antimicrobial agents for multiple types of organisms. BUT don't confuse this with there being infections at DIFFERENT body sites.
- As per our usual practice, we will consider a diagnosis as present if the clinical team thinks it's present and are treating it, with the exception that the team initially treated for the possible 2nd type of infection but then decided it likely was NOT present and stopped those agents.
- And remember that Infectious organism, unknown is used when the the specific organism is unknown (this could be not knowing the TYPE of organism, or suspecting the type but not having identified the specific organism of that type), while when the organism has been identified but it's not in our bug list, THEN use Bacteria, NOS, Virus, NOS or Fungus or yeast, NOS.
Infections in ICD10 have combined coding requirements for some of their pathogens. Any that have antibiotic resistances would store those as Combined ICD10 codes as well. If the infection is acquired in the hospital, see Nosocomial infection, NOS. See Lab and culture reports for confirmation and details about tests. See Infections in ICD10 for more general info.
