Subluxation of C3/C4 cervical vertebrae, initial encounter

This code signifies a partial dislocation of the C3 and C4 vertebrae in the cervical spine. This means the vertebral bodies are misaligned, but their articular surfaces remain in partial contact, often resulting from trauma or degenerative changes. It describes the initial presentation and treatment of this specific spinal injury.

Apply this code when documentation clearly states a subluxation of the C3/C4 cervical vertebrae, particularly in an acute injury setting. This code is appropriate for the initial encounter where the patient is receiving active treatment for the injury. Supporting documentation would include imaging reports (X-ray, CT, MRI) confirming the subluxation and physician notes detailing the injury mechanism and initial management.

• Ensure the documentation specifies "subluxation" and not a complete "dislocation" (which would use a different code).
• Verify the specific vertebral levels involved (C3/C4) as other cervical levels have distinct codes.
• The "A" in the seventh character indicates an initial encounter; subsequent encounters for the same injury will require different seventh characters (e.g., D for subsequent, S for sequela).
