M62.0Separation of muscle (nontraumatic)

M62.0 is the ICD-10-CM diagnosis code for separation of muscle (nontraumatic). 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), M62.0 is specifically for separation of muscle (nontraumatic). Related codes cover other rupture of muscle (nontraumatic) (M62.1), nontraumatic ischemic infarction of muscle (M62.2), 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: M62.00 (unspecified site), M62.01 (shoulder), M62.02 (upper arm), M62.03 (forearm), M62.04 (hand), M62.05 (thigh), M62.06 (lower leg), M62.07 (ankle and foot) and 1 more.

Don't report M62.0 together with the conditions in its Excludes1 note: diastasis recti complicating pregnancy, labor and delivery (O71.8) and traumatic separation of muscle- see strain of muscle by body region.

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