R335
R335 – Reconstruction mandible - complete
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
A surgical procedure for the complete, unilateral reconstruction of the mandible with bone grafts* and/or a plate or prosthesis. This procedure is listed under the Orthognathic Surgery section for the Skull and Mandible.
When to Use
- Use R335 for complete, unilateral mandibular reconstruction involving bone grafting, rigid fixation plates, or custom prostheses.
- Select R335 when the procedure involves a full segment replacement, distinguishing it from R334 which is typically reserved for partial or less extensive mandibular repairs.
Common Pitfalls
- Billing R335 alongside other mandibular surgical codes (e.g., R645 or R646) without clear documentation of separate, distinct procedures will trigger a rejection for unbundling.
- Failure to document the specific use of bone grafts or prosthetic hardware in the operative report is a frequent cause for audit recovery, as the code definition explicitly requires these components.
Billing Tips
- Ensure the operative report explicitly details the 'complete' nature of the reconstruction to justify the use of R335 over lower-valued partial reconstruction codes.
- If the procedure is performed as a trauma case, ensure the Injury Severity Score (ISS) is documented in the chart to support the E420 trauma premium.
