In ICD-10-CM, coders will report codes in the ­S43- series (dislocation and sprain of joints and ligaments of ­shoulder girdle) when a physician documents a subluxation or dislocation of the shoulder joint. These codes require seven characters, including a seventh character to denote the encounter (initial, subsequent, or sequela).

Subluxations and dislocations of the shoulder are classified by the bone or joint involved and are further specified by laterality. For a subluxation or dislocation of one of the shoulder joints, coders would choose among these subcategories:
  • S43.0, subluxation and dislocation of shoulder joint
  • S43.1, subluxation and dislocation of acromio­clavicular joint
  • S43.2, subluxation and dislocation of sterno­clavicular joint
  • S43.3, subluxation and dislocation of other and ­unspecified parts of shoulder girdle
The codes for the specific joints are then further subdivided to include specific types of subluxations and dislocations, laterality, and encounter. For example, category S43.1 (subluxation and dislocation of acromioclavicular joint) is subdivided into the following categories:
  • S43.10, unspecified dislocation of acromioclavicular joint
  • S43.11, subluxation of acromioclavicular joint
  • S43.12, dislocation of acromioclavicular joint, 100%-200% displacement
  • S43.13, dislocation of acromioclavicular joint, greater than 200% displacement
  • S43.14, inferior dislocation of acromioclavicular joint
  • S43.15, posterior dislocation of acromioclavicular joint
The tip is adapted from “ICD-10 anatomy refresher: Shoulder” in the October Briefings on APCs.
