L806 – Bronchial, oesophageal, gastric, endometrial or other brushings and washings
OHIP Dermatology Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This service covers the professional interpretation by a pathologist of cellular samples collected via brushing or washing techniques from various body sites, including but not limited to, the bronchus, oesophagus, stomach, and endometrium. The analysis involves assessing cellular abnormalities, flora, or other specific features as required for diagnosis. As with all insured services, appropriate medical records must be maintained to support medical necessity as per .
When to Use
- Use L806 for the cytopathological interpretation of brushings obtained during endoscopic procedures, such as bronchial or esophageal brushings, where the primary diagnostic focus is cellular morphology.
- Select L806 for endometrial washings or brushings collected for diagnostic evaluation, distinguishing this from L804 which is typically reserved for fine needle aspiration cytology.
Common Pitfalls
- Billing L806 in conjunction with L805 or L808 for the same specimen site will trigger a rejection for duplicate or overlapping service claims.
- Submitting L806 for tissue biopsies that require histological sectioning rather than cytological brushing/washing will lead to audit recovery, as these should be billed under the appropriate surgical pathology codes.
Billing Tips
- Ensure the requisition clearly specifies the collection technique as 'brushing' or 'washing' to justify the use of L806 over other cytopathology codes like L810.
