E318 – Incision and drainage of extensive haematoma of pinna with packing of ear and external compression dressing - local anaesthetic
OHIP Surgical Assists Code — AURAL SURGICAL PROCEDURES · Schedule of Benefits
This procedure involves the incision and drainage of an extensive haematoma of the pinna, performed under local anaesthetic. The service also includes the packing of the ear and the application of an external compression dressing. This code is distinct from E317, which is for the same procedure but under general anaesthetic. This service is prefixed with a '#', meaning the physician is not responsible for providing premises, equipment, supplies, and personnel when performed outside of a hospital or ICHSC, as per and .
When to Use
- Use E318 for the definitive drainage and compression dressing of an auricular haematoma performed in an office or emergency setting under local anaesthetic.
- Choose E318 over E317 when the procedure is performed without the involvement of an anaesthesiologist or general anaesthetic agents.
Common Pitfalls
- Billing E318 in conjunction with a minor assessment code for the same encounter is often rejected; ensure the procedure code captures the full scope of the visit.
- Failure to document the specific use of a compression dressing can lead to audit recovery, as the code explicitly requires this component for validity.
Billing Tips
- Since E318 is a '#' prefixed code, you are not responsible for the facility overhead, making it appropriate for office-based procedures where you do not supply the surgical tray or sterile environment.
- If the procedure is performed after hours in an emergency setting, ensure you append the appropriate E409 or E410 premium to the E318 base fee to capture the non-elective nature of the intervention.
