M93.0Slipped upper femoral epiphysis (nontraumatic)

M93.0 is the ICD-10-CM diagnosis code for slipped upper femoral epiphysis (nontraumatic). 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 8 subcodes must be used instead.

Within M93 (other osteochondropathies), M93.0 is specifically for slipped upper femoral epiphysis (nontraumatic). Related codes cover Kienbock's disease of adults (M93.1), Osteochondritis dissecans (M93.2), other specified osteochondropathies (M93.8) and osteochondropathy, unspecified (M93.9).

To report this condition, pick the subcode that matches the documentation: M93.00 ((nontraumatic)), M93.01 ((nontraumatic)), M93.02 ((nontraumatic)), M93.03 ((nontraumatic)), M93.04 ((nontraumatic)), M93.05 ((nontraumatic)), M93.06 ((nontraumatic)) and M93.07 ((nontraumatic)).

Use an additional code for associated chondrolysis (M94.3).

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