M93.07Acute on chronic slipped upper femoral epiphysis, unspecified stability (nontraumatic)

M93.07 is the ICD-10-CM diagnosis code for acute on chronic slipped upper femoral epiphysis, unspecified stability (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 4 subcodes must be used instead.

Within M93.0, choose M93.07 (Acute on chronic slipped upper femoral epiphysis, unspecified stability (nontraumatic)) only when documentation doesn't support a more specific option: unspecified slipped upper femoral epiphysis (nontraumatic) (M93.00), acute slipped upper femoral epiphysis, stable (nontraumatic) (M93.01), chronic slipped upper femoral epiphysis, stable (nontraumatic) (M93.02), acute on chronic slipped upper femoral epiphysis, stable (nontraumatic) (M93.03), acute slipped upper femoral epiphysis, unstable (nontraumatic) (M93.04), acute on chronic slipped upper femoral epiphysis, unstable (nontraumatic) (M93.05) and acute slipped upper femoral epiphysis, unspecified stability (nontraumatic) (M93.06).

To report this condition, pick the subcode that matches the documentation: M93.071 (right hip), M93.072 (left hip), M93.073 (unspecified hip) and M93.074 (bilateral hips).
