Subluxation of C0/C1 cervical vertebrae, subs encntr

This code signifies a partial dislocation or misalignment of the atlanto-occipital joint (C0/C1) in the cervical spine. It indicates that the patient is receiving active treatment for this specific subluxation, but it is not the initial encounter for the condition.

Use this code for follow-up visits, cast changes, or medication adjustments when the patient is still undergoing active treatment for a C0/C1 subluxation. Documentation should clearly state the diagnosis of C0/C1 subluxation and indicate that the encounter is subsequent to the initial treatment.

• Ensure documentation specifies "subluxation" and not a complete "dislocation" (which would be coded differently).
• Verify that the encounter is for active treatment and not for sequelae or aftercare once treatment is complete.
• Confirm the specific vertebral level (C0/C1) is documented to avoid confusion with other cervical subluxations.
