L801 – Metabolic Bone Studies
OHIP Dermatology Code — Laboratory Medicine · Schedule of Benefits
Payable for the professional interpretation of metabolic bone studies as part of an anatomic pathology assessment. This service falls under the subcategory of Surgical Pathology within Laboratory Medicine.
When to Use
- Use L801 when performing a professional interpretation of a bone biopsy specimen specifically for metabolic bone disease, distinct from routine surgical pathology assessments.
- Apply this code when the diagnostic workup requires specialized histomorphometric analysis of bone tissue that exceeds the scope of standard L861-L867 surgical pathology codes.
Common Pitfalls
- Billing L801 in conjunction with standard L861-L867 codes for the same specimen is often flagged as unbundling unless the metabolic study represents a distinct, separately requested diagnostic procedure.
- Submitting L801 without clear evidence of a metabolic bone disease workup in the pathology report will lead to audit recovery, as it is not a generic code for all bone biopsies.
Billing Tips
- Ensure the pathology report explicitly details the metabolic parameters assessed to justify the L801 fee over standard surgical pathology codes.
