M24.37Pathological dislocation of ankle and foot, not elsewhere classified

M24.37 is the ICD-10-CM diagnosis code for pathological dislocation of ankle and foot, not elsewhere classified. It belongs to category M24 (other specific joint derangements), block M20-M25 (other joint 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 6 subcodes must be used instead.

Within M24.3 (pathological dislocation of joint, not elsewhere classified), M24.37 is specifically for pathological dislocation of ankle and foot, not elsewhere classified. Related codes cover unspecified joint, not elsewhere classified (M24.30), shoulder, not elsewhere classified (M24.31), elbow, not elsewhere classified (M24.32), wrist, not elsewhere classified (M24.33), hand, not elsewhere classified (M24.34), hip, not elsewhere classified (M24.35), knee, not elsewhere classified (M24.36) and other specified joint, not elsewhere classified (M24.39).

To report this condition, pick the subcode that matches the documentation: M24.371 (classified), M24.372 (classified), M24.373 (classified), M24.374 (classified), M24.375 (classified) and M24.376 (classified).

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