Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code M60:

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Information

  • DERMATOMYOSITIS-. a subacute or chronic inflammatory disease of muscle and skin marked by proximal muscle weakness and a characteristic skin rash. the illness occurs with approximately equal frequency in children and adults. the skin lesions usually take the form of a purplish rash or less often an exfoliative dermatitis involving the nose cheeks forehead upper trunk and arms. the disease is associated with a complement mediated intramuscular microangiopathy leading to loss of capillaries muscle ischemia muscle fiber necrosis and perifascicular atrophy. the childhood form of this disease tends to evolve into a systemic vasculitis. dermatomyositis may occur in association with malignant neoplasms. from adams et al. principles of neurology 6th ed pp1405 6
  • MYOSITIS-. inflammation of a muscle or muscle tissue.
  • MYOSITIS OSSIFICANS-. a disease characterized by bony deposits or the ossification of muscle tissue.
  • POLYMYOSITIS-. diseases characterized by inflammation involving multiple muscles. this may occur as an acute or chronic condition associated with medication toxicity drug toxicity; connective tissue diseases; infections; malignant neoplasms; and other disorders. the term polymyositis is frequently used to refer to a specific clinical entity characterized by subacute or slowly progressing symmetrical weakness primarily affecting the proximal limb and trunk muscles. the illness may occur at any age but is most frequent in the fourth to sixth decade of life. weakness of pharyngeal and laryngeal muscles interstitial lung disease and inflammation of the myocardium may also occur. muscle biopsy reveals widespread destruction of segments of muscle fibers and an inflammatory cellular response. adams et al. principles of neurology 6th ed pp1404 9
  • MYOSITIS INCLUSION BODY-. progressive myopathies characterized by the presence of inclusion bodies on muscle biopsy. sporadic and hereditary forms have been described. the sporadic form is an acquired adult onset inflammatory vacuolar myopathy affecting proximal and distal muscles. familial forms usually begin in childhood and lack inflammatory changes. both forms feature intracytoplasmic and intranuclear inclusions in muscle tissue. adams et al. principles of neurology 6th ed pp1409 10
  • NERVOUS SYSTEM AUTOIMMUNE DISEASE EXPERIMENTAL-. experimental animal models for human autoimmune diseases of the nervous system. they include guillain barre syndrome see neuritis autoimmune experimental; myasthenia gravis see myasthenia gravis autoimmune experimental; and multiple sclerosis see encephalomyelitis autoimmune experimental.
  • PYOMYOSITIS-. an intramuscular suppuration of the large skeletal muscle groups. it is associated with infection such as staphylococcus aureus and pyoderma. it was known as a tropical disease but is increasing among the immunocompromised immunocompromised host. symptoms include muscle pain fever and leucocytosis. it has been diagnosed by mri scans.
  • ORBITAL MYOSITIS-. inflammation of the extraocular muscle of the eye. it is characterized by swelling which can lead to ischemia fibrosis or orbital pseudotumor.

Information for Patients


Myositis

Myositis means inflammation of the muscles that you use to move your body. An injury, infection, or autoimmune disease can cause it. Two specific kinds are polymyositis and dermatomyositis. Polymyositis causes muscle weakness, usually in the muscles closest to the trunk of your body. Dermatomyositis causes muscle weakness, plus a skin rash.

Other symptoms of myositis may include

  • Fatigue after walking or standing
  • Tripping or falling
  • Trouble swallowing or breathing

Doctors may use a physical exam, lab tests, imaging tests and a muscle biopsy to diagnose myositis. There is no cure for these diseases, but you can treat the symptoms. Polymyositis and dermatomyositis are first treated with high doses of a corticosteroid. Other options include medications, physical therapy, exercise, heat therapy, assistive devices, and rest.
