X329 – Metastatic disease of bone
OHIP Laboratory Code — RADIATION ONCOLOGY · Schedule of Benefits
Treatment for metastatic disease of bone using non-sealed source radioisotopes. According to the preamble for Radioisotopes on page , the fee for this service includes treatment planning, dosage calculation, and the preparation of materials. Appropriate visit and procedural benefits may be claimed in addition.
When to Use
- Use X329 for the administration of non-sealed radioisotopes specifically for the palliative treatment of painful bone metastases.
- Use this code when the procedure involves the complete process of treatment planning, dosage calculation, and material preparation as defined in the Radiation Oncology preamble.
Common Pitfalls
- Do not bill X329 in conjunction with other radiation oncology procedural codes that already include the 'preparation of materials' component, as this constitutes double-billing.
- Avoid billing X329 as a standalone service without an associated visit or consultation code, as the OHIP schedule explicitly permits claiming additional visit benefits for the same encounter.
Billing Tips
- Always append the appropriate visit or consultation code on the same claim to ensure you are compensated for the clinical assessment, as X329 only covers the technical procedure.
- Ensure that the documentation clearly distinguishes between the technical component (X329) and the professional assessment (visit code) to satisfy audit requirements regarding the inclusion of planning and dosage calculation.
