Dislocation of other parts of thorax, initial encounter

This code signifies the displacement of a thoracic joint, excluding the sternum, ribs, or vertebrae, from its normal anatomical position. This injury typically involves structures like the costochondral or costovertebral joints, or other less common articulations within the chest wall.

Apply this code for initial encounters involving acute dislocations of thoracic structures such as the costochondral junction, costovertebral joint, or sternoclavicular joint (when the primary injury is considered a thoracic dislocation rather than a shoulder girdle injury). This code is appropriate when the specific dislocated part is not covered by more specific codes for sternum, rib, or vertebral dislocations.

• Ensure documentation clearly specifies a dislocation of a thoracic component other than the sternum, rib, or vertebra.
• Verify that this is the patient's initial encounter for this specific injury.
• Distinguish from sprains/strains (S23.3-), which involve ligamentous injury without complete joint separation.
