Type 2 Excludes Help
A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (M60) and the excluded code together.

    Disorders of muscles
Clinical Information
  • A disorder characterized by inflammation involving the skeletal muscles.
  • An inflammatory process affecting the skeletal muscles. Causes include infections, injuries, and autoimmune disorders.
  • Inflammation of a muscle or muscle tissue.
  • Inflammation of skeletal muscle, not including inflammation of cardiac muscle
  • Inflammation of skeletal muscle.
  • Myositis is inflammation of your skeletal muscles, which are also called the voluntary muscles. These are the muscles you consciously control that help you move your body. An injury, infection or autoimmune disease can cause myositis. The diseases dermatomyositis and polymyositis both involve myositis. Polymyositis causes muscle weakness, usually in the muscles closest to the trunk of your body. Dermatomyositis causes muscle weakness, plus a skin rash. Both diseases are usually treated with prednisone, a steroid medicine, and sometimes other medicines.
