About M93.2
M93.2 is the ICD-10-CM diagnosis code for Osteochondritis dissecans. It belongs to category M93 (other osteochondropathies), block M91-M94 (Chondropathies) 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 10 subcodes must be used instead.
Within M93 (other osteochondropathies), M93.2 is specifically for Osteochondritis dissecans. Related codes cover slipped upper femoral epiphysis (nontraumatic) (M93.0), Kienbock's disease of adults (M93.1), other specified osteochondropathies (M93.8) and osteochondropathy, unspecified (M93.9).
To report this condition, pick the subcode that matches the documentation: M93.20 (of unspecified site), M93.21 (of shoulder), M93.22 (of elbow), M93.23 (of wrist), M93.24 (of joints of hand), M93.25 (of hip), M93.26 (knee), M93.27 (of ankle and joints of foot) and 2 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
