Subluxation of C2/C3 cervical vertebrae, subs encntr

This code signifies a partial dislocation or misalignment of the second and third cervical vertebrae (C2/C3) in the neck. It indicates that the patient is receiving follow-up care for an injury that occurred previously, rather than the initial treatment. This condition can lead to neck pain, stiffness, and neurological symptoms if nerves are compressed.

Apply this code for patients presenting for ongoing treatment, such as physical therapy, chiropractic adjustments, or follow-up evaluations, after the initial acute phase of a C2/C3 subluxation has passed. Documentation should clearly state "subsequent encounter," "follow-up," or indicate ongoing care for a previously diagnosed subluxation.

• Ensure the encounter is not for the initial treatment of the injury; otherwise, an initial encounter code would be more appropriate.
• Verify laterality if applicable to other spinal subluxation codes, though C2/C3 is typically midline.
• Always review the full documentation to confirm the specific vertebral level and the encounter type (initial, subsequent, sequela).
