Type III traum spondylolysis of third cervcal vert, sequela

This code signifies a chronic or late effect of a traumatic spondylolisthesis affecting the third cervical vertebra (C3), specifically a Type III fracture. This type typically involves a bilateral fracture of the pedicles or articular processes, leading to anterior displacement of C3 on C4. The "sequela" indicates that this code is used for conditions arising as a direct result of the initial injury, after the acute phase of healing has passed.

Apply this code when documenting long-term complications or residual conditions stemming from a Type III traumatic spondylolisthesis of C3. This includes chronic pain, neurological deficits, or instability that persists after the initial injury has stabilized. Documentation should clearly state the C3 involvement, the Type III classification, and explicitly link the current condition to the past traumatic spondylolisthesis, often using terms like "due to prior injury" or "sequela of."

• Ensure the documentation specifies "Type III" and the "third cervical vertebra" (C3) for accurate code assignment.
• The "S" in the 7th character indicates "sequela," meaning this code is for late effects, not the initial acute injury.
• Always sequence this code after the primary diagnosis describing the specific sequela (e.g., chronic pain, myelopathy).
