M63: Disorders of muscle in diseases classified elsewhere
The group of conditions under the category "Disorders of muscle in diseases classified elsewhere" refers to muscle disorders that are not caused primarily by a muscle disease but are due to other underlying conditions. Symptoms and clinical presentations of these disorders often vary widely as they are dictated by the root cause of the disease. However, common features may include muscle weakness, muscle cramps, stiffness, and varying degrees of discomfort or pain. The progression and development of these disorders are largely dependent on the course of the underlying disease. Some of these muscle disorders are seen in individuals with systemic illnesses, infectious diseases, or certain genetic conditions. These disorders affect the musculoskeletal system, and specifically, they impact the function and structure of the muscle tissue. This cluster of conditions is not typically transmitted from person to person, but the underlying diseases causing these disorders may have different modes of transmission.
