ICD-10 Codes for Shoulder Dislocation
The ICD-10 codes for shoulder dislocation are S43.0 series codes, which must include laterality (left, right, or unspecified) and can be further specified by the type of dislocation (anterior, posterior, inferior, or unspecified).
Primary ICD-10 Codes for Shoulder Dislocation
The specific codes are:
S43.00- Unspecified subluxation and dislocation of shoulder joint
- S43.001A - Right shoulder, initial encounter
- S43.002A - Left shoulder, initial encounter
- S43.003A - Unspecified shoulder, initial encounter
S43.01- Anterior subluxation and dislocation of humerus
- S43.011A - Right shoulder, initial encounter
- S43.012A - Left shoulder, initial encounter
- S43.013A - Unspecified shoulder, initial encounter
S43.02- Posterior subluxation and dislocation of humerus
- S43.021A - Right shoulder, initial encounter
- S43.022A - Left shoulder, initial encounter
- S43.023A - Unspecified shoulder, initial encounter
S43.03- Inferior subluxation and dislocation of humerus
- S43.031A - Right shoulder, initial encounter
- S43.032A - Left shoulder, initial encounter
- S43.033A - Unspecified shoulder, initial encounter
Seventh Character Extensions
The seventh character in the code indicates the encounter type:
- A - Initial encounter
- D - Subsequent encounter
- S - Sequela (complication or condition that arises as a consequence of the injury)
Associated Conditions and Complications
When coding shoulder dislocations, consider these associated conditions that may require additional codes:
- Fractures (Hill-Sachs lesion, Bankart fracture)
- Rotator cuff tears
- Labral tears
- Brachial plexus injuries
- Vascular injuries
Documentation Requirements
For accurate coding, documentation should include:
- Laterality (right, left, or bilateral)
- Type of dislocation (anterior, posterior, inferior)
- Whether it's an initial or subsequent encounter
- Any associated injuries or complications
- Mechanism of injury when known
Clinical Considerations
Anterior dislocations account for approximately 95% of all shoulder dislocations 1, while posterior and inferior dislocations are less common. Proper identification of the type of dislocation is essential for accurate coding and appropriate treatment planning.
The American College of Radiology recommends standard radiographs, including anteroposterior views in internal and external rotation, and axillary or scapula-Y view, for evaluating dislocations and shoulder alignment 2.
