E323 – Myringoplasty
OHIP Surgical Assists Code — Y. Ocular and Aural Surgical Procedures · Schedule of Benefits
Myringoplasty is a surgical repair of the tympanic membrane (eardrum). It is listed as a repair procedure for the middle ear in the Schedule of Benefits.
When to Use
- Use E323 specifically for the surgical repair of a tympanic membrane perforation when no other major middle ear reconstruction (such as tympanoplasty) is performed.
- Use E323 for simple myringoplasty procedures; do not use E320 (Myringotomy) or E322 (Tympanoplasty) as these represent distinct clinical interventions with different procedural requirements.
Common Pitfalls
- Billing E323 alongside other middle ear procedures without ensuring the documentation clearly distinguishes the separate surgical sites, as this often triggers manual review or rejection.
- Attempting to bill for a surgical assistant using standard assistant codes without prior authorization; you must submit a letter to a medical consultant and use M400B to obtain payment for assistance.
Billing Tips
- Ensure the procedure start time is clearly documented to support the application of E409 or E410 if the surgery is non-elective and performed outside standard hours.
- If the patient is under 16 years of age, always verify the correct age premium (e.g., AGE_PREMIUM_LT16Y) is applied to the base fee of $209.05 to maximize the claim value.
