L830 – Terminal Transferase by Immunofluorescence
OHIP Dermatology Code — Laboratory Medicine · Schedule of Benefits
L830 is a laboratory medicine procedure listed under the Haematopathology subsection. This test involves the detection of terminal transferase using immunofluorescence.
When to Use
- Use L830 specifically for the detection of Terminal Deoxynucleotidyl Transferase (TdT) in suspected acute lymphoblastic leukemia or lymphoblastic lymphoma cases.
- Select L830 when immunofluorescence is the required methodology for TdT identification, distinguishing it from flow cytometry-based markers or other immunohistochemical stains like L829.
Common Pitfalls
- Billing L830 alongside L829 for the same specimen can trigger a rejection if the ministry deems the testing redundant or part of a bundled diagnostic panel.
- Claiming L830 without a corresponding pathology requisition or diagnostic report that explicitly confirms the immunofluorescence technique will lead to audit recovery.
Billing Tips
- Ensure the laboratory report clearly differentiates the use of immunofluorescence for L830 from other enzyme-linked or flow-based assays to justify the specific fee code.
