M24.4Recurrent dislocation of joint

M24.4 is the ICD-10-CM diagnosis code for recurrent dislocation of joint. 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 9 subcodes must be used instead.

Within M24 (other specific joint derangements), M24.4 is specifically for recurrent dislocation of joint. Related codes cover Loose body in joint (M24.0), other articular cartilage disorders (M24.1), disorder of ligament (M24.2), pathological dislocation of joint, not elsewhere classified (M24.3), contracture of joint (M24.5), ankylosis of joint (M24.6), Protrusio acetabuli (M24.7), not elsewhere classified (M24.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: M24.40 (joint), M24.41 (shoulder), M24.42 (elbow), M24.43 (wrist), M24.44 (finger(s)), M24.45 (hip), M24.46 (knee), M24.47 (toes) and 1 more.

The conditions in its Excludes2 note aren't part of M24.4, but may be coded alongside it if the patient has both: recurrent dislocation of patella (M22.0-M22.1) and recurrent vertebral dislocation (M43.3-, M43.4, M43.5-).

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