S43.2Subluxation and dislocation of sternoclavicular joint

S43.2 is the ICD-10-CM diagnosis code for 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 3 subcodes must be used instead.

Within S43 (dislocation and sprain of joints and ligaments of shoulder girdle), S43.2 is specifically for subluxation and dislocation of sternoclavicular joint. Related codes cover subluxation and dislocation of shoulder joint (S43.0), subluxation and dislocation of acromioclavicular joint (S43.1), subluxation and dislocation of other and unspecified parts of shoulder girdle (S43.3), sprain of shoulder joint (S43.4), sprain of acromioclavicular joint (S43.5), sprain of sternoclavicular joint (S43.6), sprain of other specified parts of shoulder girdle (S43.8) and sprain of unspecified parts of shoulder girdle (S43.9).

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.
