Posterior subluxation of unsp sternoclavicular joint, subs

This code describes a partial dislocation of the sternoclavicular (SC) joint where the clavicle shifts backward relative to the sternum. It specifically refers to a posterior subluxation, indicating an incomplete separation of the joint surfaces. The "unspecified" nature means the laterality (left or right) is not documented.

Apply this code for follow-up encounters when a patient is receiving active treatment for a posterior sternoclavicular subluxation, such as physical therapy, cast care, or medication management. This includes subsequent visits after the initial injury has been diagnosed and treatment has begun.

• Ensure documentation clearly states "posterior subluxation" and that it's a subsequent encounter.
• Verify laterality is truly unspecified; if left or right is documented, a more specific code should be used.
• Do not use for initial encounters or for sequelae (late effects) of the injury.
