Posterior subluxation of unsp sternoclav jt, sequela

This code signifies a partial dislocation of the sternoclavicular joint, specifically where the clavicle has shifted backward relative to the sternum. The "unspecified" nature indicates that the laterality (left or right) of the affected joint is not documented. The "sequela" designation means this is a residual condition or complication arising from an initial injury, rather than the acute injury itself.

Use this code when documenting a chronic or long-standing posterior subluxation of the sternoclavicular joint, where the original injury has healed but this partial dislocation persists as a consequence. This would apply in follow-up encounters for patients experiencing ongoing symptoms or functional limitations directly attributable to the subluxation, without explicit mention of which side is affected.

• Ensure documentation clearly states "posterior subluxation" and that it is a chronic or residual condition.
• Only use "unspecified" when the medical record does not specify laterality (left or right).
• Remember the "S" seventh character indicates a sequela, meaning the patient is seen for a late effect of an earlier injury.
