About S43.02

S43.02 is the ICD-10-CM diagnosis code for posterior subluxation and dislocation of humerus. 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 S43.0 (subluxation and dislocation of shoulder joint), S43.02 is specifically for posterior subluxation and dislocation of humerus. Related codes cover unspecified subluxation and dislocation of shoulder joint (S43.00), anterior subluxation and dislocation of humerus (S43.01), inferior subluxation and dislocation of humerus (S43.03) and other subluxation and dislocation of shoulder joint (S43.08).

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.
