Scarlet fever with myocarditis

This code identifies scarlet fever that has progressed to involve inflammation of the heart muscle. Scarlet fever is a bacterial infection, typically caused by Group A Streptococcus, characterized by a distinctive rash. Myocarditis, in this context, signifies a serious cardiac complication directly resulting from the streptococcal infection.

Apply this code when documentation clearly indicates a diagnosis of scarlet fever with co-occurring myocarditis. This typically involves a patient presenting with symptoms of scarlet fever alongside clinical or diagnostic findings consistent with myocardial inflammation, such as elevated cardiac enzymes, EKG changes, or echocardiographic abnormalities.

• Ensure documentation explicitly links the myocarditis to the scarlet fever; otherwise, separate codes for each condition may be necessary.
• Do not use this code for myocarditis due to other infectious agents or non-infectious causes.
• Consider additional codes for specific manifestations or complications of myocarditis, if documented.
