G72: Other myopathies

G72.8: Other specified myopathies

Other specified myopathies, delineated in the ICD-10 under the code G72.8, refers to specific categories of muscle diseases not otherwise designated in other codes. These conditions affect the muscle fibers, which are the basic units of muscles responsible for muscular strength and movement. Underlying causes can range from genetic disorders to certain medicines or toxins that adversely affect muscle health. Symptoms commonly seen in these disorders include muscle weakness, fatigue, cramps, stiffness, and in severe cases, difficulty in swallowing or breathing. The progression and the severity of these myopathies can differ greatly from person to person, with some cases worsening gradually over time, while others remain stable. These conditions mainly impinge upon the muscular system, but because muscles are crucial to many body functions, other systems such as respiratory or cardiac may also be affected.
