About M93.8

M93.8 is the ICD-10-CM diagnosis code for other specified osteochondropathies. 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, choose M93.8 (Other specified osteochondropathies) only when documentation doesn't support a more specific option: slipped upper femoral epiphysis (nontraumatic) (M93.0), Kienbock's disease of adults (M93.1), Osteochondritis dissecans (M93.2) and osteochondropathy, unspecified (M93.9).

To report this condition, pick the subcode that matches the documentation: M93.80 (of unspecified site), M93.81 (of shoulder), M93.82 (of upper arm), M93.83 (of forearm), M93.84 (of hand), M93.85 (of thigh), M93.86 (lower leg), M93.87 (of ankle and 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.
