E345 – Temporal bone resection
OHIP Surgical Assists Code — Y. Ocular and Aural Surgical Procedures · Schedule of Benefits
Temporal bone resection is a surgical procedure listed under the Inner Ear Repair sub-section of the Ocular and Aural Surgical Procedures section of the Schedule. The listed fee for the surgeon (suffix A) is $1379.10. See the unitBasedInfo section for details on assistant and anaesthesia fee calculations.
When to Use
- Use E345 for formal resection of the temporal bone, distinguishing it from simpler mastoidectomy procedures like E331 or E332.
- Select E345 when the surgical intent and operative report confirm a formal resection of the temporal bone structure, rather than limited debridement or biopsy.
Common Pitfalls
- Billing E345 in conjunction with other ear procedures without ensuring the services are not considered 'included' or 'incidental' under the General Preamble rules for multiple procedures.
- Failing to document the specific extent of the resection, which can lead to audit reclassifications if the procedure performed is found to be a less complex mastoid surgery (e.g., E331).
Billing Tips
- Ensure that if an assistant is required, the assistant's claim (suffix B) is submitted with the appropriate time units, as E345 is a major procedure that typically justifies surgical assistance.
