L042 – L042
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L042 for the professional component of a diagnostic Pap smear when the physician performs the collection and interpretation of the specimen.
- Apply this code when submitting a claim for a cervical cytology screening that meets the provincial laboratory quality standards for diagnostic reporting.
Common Pitfalls
- Do not bill L042 in conjunction with a general assessment code like A007, as the laboratory component is considered inclusive of the visit fee.
- Submitting L042 without the corresponding laboratory requisition number or site-specific diagnostic code will trigger an automatic rejection.
Billing Tips
- Ensure the diagnostic code used on the L042 claim matches the clinical indication documented on the lab requisition to avoid audit flags for unnecessary testing.
