Dislocation of C2/C3 cervical vertebrae, subs encntr

This code signifies a dislocation between the second and third cervical vertebrae (C2/C3) that is being treated during a subsequent encounter. This injury involves the displacement of these vertebral bodies from their normal anatomical alignment, often resulting from significant trauma.

Apply this code when a patient is receiving follow-up care for a previously diagnosed C2/C3 cervical dislocation. This includes rehabilitation, cast changes, medication management, or monitoring for healing and complications after the initial treatment phase. Documentation should clearly indicate "subsequent encounter" or "follow-up" for the dislocation.

• Ensure documentation specifies the subsequent nature of the encounter, not the initial treatment.
• Distinguish between dislocation (S13.13-) and subluxation (S13.11- or S13.12-) of the cervical vertebrae.
• Always code the specific vertebral level (C2/C3) as indicated in the medical record.
