S43.20Unspecified subluxation and dislocation of sternoclavicular joint

S43.20 is the ICD-10-CM diagnosis code for unspecified subluxation and dislocation of sternoclavicular joint. It belongs to category S43 (dislocation and sprain of joints and ligaments of shoulder girdle), block S40-S49 (injuries to the shoulder and upper arm) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

Within S43.2, choose S43.20 (Unspecified subluxation and dislocation of sternoclavicular joint) only when documentation doesn't support a more specific option: anterior subluxation and dislocation of sternoclavicular joint (S43.21) and posterior subluxation and dislocation of sternoclavicular joint (S43.22).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

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