M62.1Other rupture of muscle (nontraumatic)

M62.1 is the ICD-10-CM diagnosis code for other rupture 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, choose M62.1 (Other rupture of muscle (nontraumatic)) only when documentation doesn't support a more specific option: separation of muscle (nontraumatic) (M62.0), 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: M62.10 (unspecified site), M62.11 (shoulder), M62.12 (upper arm), M62.13 (forearm), M62.14 (hand), M62.15 (thigh), M62.16 (lower leg), M62.17 (ankle and foot) and 1 more.

Don't report M62.1 together with the conditions in its Excludes1 note: traumatic rupture of muscle - see strain of muscle by body region.

The conditions in its Excludes2 note aren't part of M62.1, but may be coded alongside it if the patient has both: rupture of tendon (M66.-).

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