Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


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.
  • arthrogryposis multiplex congenita Q74.3
  • metabolic disorders E70 E88
  • myositis M60

Patient Education


Muscle Disorders

Your muscles help you move and help your body work. Different types of muscles have different jobs. There are many problems that can affect muscles. Muscle disorders can cause weakness, pain or even paralysis.

Causes of muscle disorders include:

  • Injury or overuse, such as sprains or strains, cramps or tendinitis
  • A genetic disorder, such as muscular dystrophy
  • Some cancers
  • Inflammation, such as myositis
  • Diseases of nerves that affect muscles
  • Infections
  • Certain medicines

Sometimes the cause of muscle disorders is unknown.
