M75.9Shoulder lesion, unspecified

M75.9 is the ICD-10-CM diagnosis code for shoulder lesion, unspecified. It belongs to category M75 (shoulder lesions), block M70-M79 (other soft tissue disorders) 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 3 subcodes must be used instead.

Within M75, choose M75.9 (Shoulder lesion, unspecified) only when documentation doesn't support a more specific option: adhesive capsulitis of shoulder (M75.0), rotator cuff tear or rupture, not specified as traumatic (M75.1), Bicipital tendinitis (M75.2), Calcific tendinitis of shoulder (M75.3), impingement syndrome of shoulder (M75.4), bursitis of shoulder (M75.5) and other shoulder lesions (M75.8).

To report this condition, pick the subcode that matches the documentation: M75.90 (unspecified shoulder), M75.91 (right shoulder) and M75.92 (left shoulder).

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