Disorders of muscles (M60-M63)

Browse all the diagnosis codes used for disorders of muscles (m60-m63). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Instructional Notations

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • dermatopolymyositis M33
  • myopathy in amyloidosis E85
  • myopathy in polyarteritis nodosa M30.0
  • myopathy in rheumatoid arthritis M05.32
  • myopathy in scleroderma M34
  • myopathy in Sjögren's syndrome M35.03
  • myopathy in systemic lupus erythematosus M32

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.
