M63: Disorders of muscle in diseases classified elsewhere
M63.2: Myositis in other infectious diseases classified elsewhere
Myositis refers to inflammation of the muscles. Code M63.2 in the ICD-10 WHO 2016 classification pertains to myositis in relation to other infectious diseases that are classified separately. This means that the myositis has been induced by another infectious disease. The main symptoms include muscle pain, tenderness, and weakness which can occur in any muscle group but usually affect those close to the trunk such as the neck, shoulders, back, and hips. These symptoms may occur suddenly or develop slowly over time. The myositis could be caused by a variety of infectious diseases ranging from bacterial, viral to parasitic infections. The disease progression can vary greatly from person to person, depending on the underlying infectious disease that has caused the myositis. As this condition is linked with an infectious disease, other symptoms related to that specific disease may also present.
