L802 – Bone marrow interpretation (Romanowsky stain)
OHIP Dermatology Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Professional interpretation of a bone marrow specimen prepared with a Romanowsky stain. This service is typically performed by a haematopathologist following a bone marrow aspiration and/or core biopsy procedure, such as Z403.
When to Use
- Use L802 when performing the professional interpretation of a bone marrow aspirate smear stained with Romanowsky stain, distinct from the technical component of the lab work.
- Bill L802 in conjunction with Z403 when you have personally performed the aspiration and subsequently interpreted the resulting stained slide.
Common Pitfalls
- Do not bill L802 if the interpretation is performed by a pathologist in a hospital setting, as this is typically covered under the global hospital budget rather than a fee-for-service claim.
- Avoid billing L802 alongside L800 or L826 for the same specimen, as these codes are mutually exclusive based on the specific staining or analysis method used.
Billing Tips
- Ensure the clinical record clearly distinguishes between the procedural code Z403 for the marrow collection and the professional interpretation code L802 to avoid duplicate payment flags.
