X325 – Application of radium or radioisotope plaque or mould
OHIP Laboratory Code — RADIATION ONCOLOGY · Schedule of Benefits
Application of a radium or radioisotope plaque or mould. The '#' prefix indicates that when this service is rendered in a hospital, the provision of premises, equipment, supplies, and personnel is funded through the hospital's budget and is not included in the physician fee (). This procedure is eligible for payment as an in-patient or out-patient service. As per the note on , in-patient services must adhere to rules for '#' services on page . For out-patient services, payment is directed to the hospital's registered Department of Radiology, even though a technical component is not separately listed.
When to Use
- Use X325 when performing the physical application of a radioisotope plaque or mould for brachytherapy, distinct from the planning or dosimetry services covered by X322 or X323.
- Apply this code for the direct supervision and placement of superficial or intracavitary radiation sources where the physician is actively involved in the application process.
Common Pitfalls
- Billing X325 for hospital-based out-patient procedures under an individual physician number rather than the registered Department of Radiology will result in payment rejection or audit recovery.
- Attempting to claim X325 in conjunction with technical fees is incorrect, as the '#' prefix explicitly mandates that hospital overhead is excluded from the physician fee.
Billing Tips
- Ensure that for out-patient hospital services, the claim is directed to the Department of Radiology to comply with the specific payment adjustment rules for '#' prefixed codes.
