M62 Other disorders of muscle

All 131 codes in the M62 family, with the PDGM clinical group, comorbidity subgroup and primary-position rule CMS assigns, read from the CMS grouper crosswalk v07.2.26 and the CDC FY2027 code file.

What CMS assigns to M62

71 of the 131 codes group to Musculoskeletal Rehabilitation; 60 are assigned no clinical group. None of the 131 is assigned a comorbidity subgroup. 71 of the 131 can lead a claim. CMS attaches a code-first note to 1 of the 131.

Code first

CMS grouper convention 127, on M62.84. Code first:

  • disorders of myoneural junction and muscle disease in diseases classified elsewhere (G73.-)
  • other and unspecified myopathies (G72.-)
  • primary disorders of muscles (G71.-)
  • underlying disease, if applicable, such as:

Descriptions are CDC’s FY2027 wording; where CMS’s grouper abbreviates one, its form is shown beneath.
