M62.2Nontraumatic ischemic infarction of muscle

M62.2 is the ICD-10-CM diagnosis code for nontraumatic ischemic infarction of muscle. It belongs to category M62 (other disorders of muscle), 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 9 subcodes must be used instead.

Within M62 (other disorders of muscle), M62.2 is specifically for nontraumatic ischemic infarction of muscle. Related codes cover separation of muscle (nontraumatic) (M62.0), other rupture of muscle (nontraumatic) (M62.1), Immobility syndrome (paraplegic) (M62.3), contracture of muscle (M62.4), muscle wasting and atrophy, not elsewhere classified (M62.5), other specified disorders of muscle (M62.8) and disorder of muscle, unspecified (M62.9).

To report this condition, pick the subcode that matches the documentation: M62.20 (unspecified site), M62.21 (shoulder), M62.22 (upper arm), M62.23 (forearm), M62.24 (hand), M62.25 (thigh), M62.26 (lower leg), M62.27 (ankle and foot) and 1 more.

Don't report M62.2 together with the conditions in its Excludes1 note: compartment syndrome (traumatic) (T79.A-), nontraumatic compartment syndrome (M79.A-), traumatic ischemia of muscle (T79.6), rhabdomyolysis (M62.82) and 1 more.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
