Unsp subluxation of unsp sternoclavicular joint, subs encntr

This code indicates a partial dislocation of the sternoclavicular joint, where the clavicle has moved out of its normal position relative to the sternum, but the joint surfaces are still in partial contact. The specific side (left or right) of the injury is not documented, and this encounter is for follow-up care after the initial treatment.

Use this code for subsequent encounters when the patient is receiving ongoing treatment, follow-up, or rehabilitation for an unspecified subluxation of the sternoclavicular joint. This applies when the medical record does not specify whether the injury is to the left or right joint.

• Requires an additional code for any associated external cause of injury, if known.
• Do not use for initial encounters or sequela; different seventh characters apply for those phases of care.
• Ensure documentation clearly supports "unspecified" laterality and "subsequent encounter" for accurate code assignment.
