Posterior subluxation of right humerus, initial encounter

This code signifies an incomplete dislocation of the right humerus where the humeral head is displaced posteriorly relative to the glenoid fossa. It indicates the initial presentation of this injury, meaning the patient is receiving active treatment for the subluxation. This condition often results from trauma or excessive external rotation and abduction of the arm.

Apply this code for patients presenting with a newly diagnosed posterior subluxation of the right shoulder. This is appropriate for the initial evaluation, imaging, and any immediate treatment such as reduction or immobilization. Subsequent encounters for follow-up care of this specific injury will require a different seventh character.

• Ensure the documentation clearly specifies "posterior" displacement and "right" side.
• Verify that this is indeed the "initial encounter" for treatment of this specific injury.
• Distinguish between subluxation (partial dislocation) and complete dislocation, as these have different codes.
