Dislocation of C4/C5 cervical vertebrae, subs encntr

This code indicates a dislocation of the cervical vertebrae between the fourth and fifth segments (C4 and C5) that is being treated or evaluated after the initial encounter for the injury. This injury involves the complete displacement of the articular surfaces of the C4 and C5 vertebrae.

Use this code for follow-up visits, rehabilitation encounters, or subsequent evaluations for a C4/C5 cervical dislocation after the acute phase of treatment. Documentation should clearly state "subsequent encounter" or indicate ongoing care for the previously diagnosed dislocation, such as cast changes, medication adjustments, or physical therapy sessions.

• Ensure the documentation specifies C4/C5. Other cervical levels have distinct codes.
• The 7th character "D" signifies subsequent encounter; do not use "A" (initial) or "S" (sequela) for this scenario.
• Always code any associated neurological deficits or spinal cord injuries separately.
