L059 – Creatinine
OHIP Dermatology Code · Schedule of Benefits
Creatinine - Laboratory Medicine (Technical Component)
When to Use
- Use L059 exclusively when billing for the technical component of a creatinine test performed in a licensed laboratory facility, not within your own office.
- Apply this code when you are the designated pathologist or laboratory physician providing a formal, written interpretative report on the creatinine result for a referred patient.
Common Pitfalls
- Billing L059 for in-office testing is a frequent audit trigger; you must use G039 for any creatinine test performed using your own office equipment.
- Submitting L059 without a corresponding written interpretative report on file will lead to clawbacks, as the fee specifically compensates for the professional interpretation, not just the technical performance.
- Attempting to bill L059 in addition to the Q040 Diabetes Management Incentive for the same patient encounter is often flagged as double-dipping, as creatinine is a constituent element of the incentive.
Billing Tips
- Ensure your clinical documentation includes a distinct, signed interpretative report for the creatinine value to satisfy the mandatory requirement for this technical fee.
- Verify that the laboratory facility's billing system is not already claiming the technical component for the same specimen to avoid duplicate submission errors.
