M62 is a header code, so it can't be reported by itself. Choose one of the 8 more specific codes beneath it.

About M62
M62 is the ICD-10-CM diagnosis code for other disorders of muscle. It belongs to block M60-M63 (disorders of muscles) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 8 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: M62.0 ((nontraumatic)), M62.1 ((nontraumatic)), M62.2 (muscle), M62.3 ((paraplegic)), M62.4 (muscle), M62.5 (classified), M62.8 (muscle) and M62.9 (unspecified).
Don't report M62 together with the conditions in its Excludes1 note: alcoholic myopathy (G72.1), cramp and spasm (R25.2), drug-induced myopathy (G72.0), myalgia (M79.1-) and 1 more.
The conditions in its Excludes2 note aren't part of M62, but may be coded alongside it if the patient has both: nontraumatic hematoma of muscle (M79.81).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
