X305 – Intracavitary treatment planning for contact x-ray therapy - first application
OHIP Laboratory Code — RADIATION ONCOLOGY · Schedule of Benefits
This service covers the intracavitary treatment planning for contact x-ray therapy, which incorporates sigmoidoscopy or proctoscopy. It is designated for the first application of the treatment course. Any repeat applications must be claimed using X306.
When to Use
- Use X305 for the initial planning session of contact x-ray therapy for rectal malignancies when the procedure includes the required sigmoidoscopy or proctoscopy.
- Apply this code specifically for the first treatment encounter in a series; subsequent sessions must transition to X306.
Common Pitfalls
- Billing X305 for repeat treatment sessions will trigger an automatic rejection as it is strictly limited to the first application.
- Failing to document the associated sigmoidoscopy or proctoscopy within the clinical note risks audit recovery, as the code definition explicitly incorporates these procedures.
Billing Tips
- Ensure the date of service matches the initial planning and first application date to avoid confusion with subsequent X306 claims.
