L845 – Specimen radiography or microradiography and interpretation
OHIP Dermatology Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This service involves the use of radiography or microradiography on a specimen for diagnostic purposes. The fee includes both the technical act of performing the imaging and the professional interpretation of the results, as outlined in the Special Procedures and Interpretation - Histology or Cytology subsection of Laboratory Medicine.
When to Use
- Use L845 for the radiographic imaging and interpretation of surgical specimens, such as breast biopsy tissue, to confirm the presence of calcifications or specific markers.
- Use this code when performing microradiography on bone or tissue samples to assess structural integrity or pathological changes that require radiographic visualization.
Common Pitfalls
- Billing L845 in addition to a standard pathology examination code (e.g., L834, L835) without a distinct, separate radiographic report in the patient record will lead to audit recovery.
- Attempting to bill L845 for general diagnostic imaging of a patient rather than a physical specimen is an incorrect application of this laboratory medicine code.
Billing Tips
- Ensure the interpretation report is physically attached or clearly referenced in the patient's chart to satisfy the documentation requirement for the professional component of the service.
- Verify that the referral source is documented, as L845 requires a valid referral from an authorized provider to be considered an insured service.
