E600 – Laryngoscopy using operating microscope
OHIP Surgical Assists Code — RESPIRATORY SURGICAL PROCEDURES · Schedule of Benefits
When to Use
- Use E600 when performing a microlaryngoscopy for vocal cord lesion excision (Z322) where the operating microscope is essential for visualization.
- Apply this code when using the operating microscope during a direct laryngoscopy for biopsy (Z292) to ensure precise tissue sampling.
Common Pitfalls
- Billing E600 alongside E643 will result in an automatic rejection as they are mutually exclusive.
- Attempting to bill E600 without an associated base laryngoscopy code (Z292, Z293, Z322, or Z323) will lead to a claim denial.
Billing Tips
- Ensure the operative report explicitly mentions the use of an operating microscope to justify the E600 premium in the event of an audit.
