L143 – L143
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L143 for the microscopic examination of a direct smear for fungi, such as a skin scraping for suspected tinea corporis.
- Apply this code when performing a KOH preparation in the office to confirm a fungal diagnosis before initiating antifungal therapy.
Common Pitfalls
- Do not bill L143 in conjunction with a general office visit fee (A007) if the visit was solely for the purpose of the specimen collection and examination.
- Avoid billing L143 if the specimen is sent to an external laboratory, as the lab will bill for the professional component of the pathology service.
Billing Tips
- Ensure the clinical indication for the fungal smear is clearly linked to the diagnostic code to avoid automated rejections for lack of medical necessity.
