Posterior subluxation of left sternoclavicular joint, init

This code signifies a partial dislocation of the left sternoclavicular (SC) joint where the clavicle shifts backward relative to the sternum. This injury often results from direct trauma to the shoulder or upper chest. Patients typically present with pain, swelling, and limited range of motion in the affected area.

Apply this code for the initial treatment of a patient diagnosed with a posterior subluxation of the left sternoclavicular joint. This includes emergency department visits, initial consultations, and the first surgical or non-surgical management of the injury.

• Ensure documentation specifies "posterior" and "left" to support this specific code.
• Verify the encounter is the "initial encounter" for this injury; subsequent care will use different encounter characters.
• Confirm the diagnosis is a subluxation, not a complete dislocation, as this impacts code selection.
