Posterior subluxation of r sternoclav jt, sequela

This code describes a partial dislocation of the right sternoclavicular (SC) joint where the clavicle has moved backward relative to the sternum. It specifically indicates that this subluxation is a long-term complication or residual effect of a previous injury or condition, rather than an acute event. The patient may experience chronic pain, instability, or limited range of motion in the affected shoulder.

Use this code for patients presenting with persistent symptoms or findings related to a previously sustained posterior subluxation of the right sternoclavicular joint. This applies when the initial injury has healed, but the subluxation remains a chronic issue requiring ongoing management. It is appropriate for follow-up encounters addressing the long-term sequelae of such an injury.

• Always assign an additional code to identify the original cause of the sequela, if known and still relevant.
• Do not use this code for acute or initial presentations of a posterior sternoclavicular subluxation; refer to acute injury codes.
• Ensure documentation clearly states "sequela" or indicates a chronic, residual nature of the subluxation.
