Dislocation of C1/C2 cervical vertebrae, subs encntr

This code signifies a dislocation between the first (atlas) and second (axis) cervical vertebrae, specifically when the patient is receiving follow-up care for this injury. This could involve ongoing treatment, rehabilitation, or monitoring after the initial acute phase of the injury.

Apply this code for patients presenting for subsequent treatment or evaluation of a C1/C2 dislocation that has already been acutely managed. Documentation should clearly indicate the encounter is not for the initial injury, but rather for ongoing care, such as cast changes, physical therapy, or follow-up imaging.

• Ensure the encounter is explicitly documented as "subsequent" or "follow-up" for the dislocation.
• Do not use this code for the initial treatment of the dislocation; refer to the appropriate "initial encounter" code.
• Always code any associated neurological deficits or spinal cord injuries separately.
