X415 – CT Spine - without IV contrast
OHIP Laboratory Code — DIAGNOSTIC RADIOLOGY · Schedule of Benefits
Computed Tomography (CT) scan of one or more spinal regions, performed without the administration of intravenous (IV) contrast material. This service encompasses both the technical performance of the imaging and the professional interpretation of the results. It is subject to the general rules for diagnostic procedures as outlined in the Schedule of Benefits.
When to Use
- Use X415 for non-contrast spinal imaging when the clinical indication does not require contrast enhancement, such as evaluating bony trauma or degenerative changes.
- Select X415 over X416 when the study protocol is strictly non-contrast, as billing X416 for a non-contrast study is a technical error.
Common Pitfalls
- Billing X415 in conjunction with E406, E407, or E408 when the interpretation was not transmitted to the referring provider within the mandatory three-hour window.
- Attempting to claim a Diagnostic Special Visit Premium alongside PACS-based after-hours premiums (E406-E408) for the same interpretation, which is prohibited.
Billing Tips
- Ensure the referring physician's name and hospital privileges are documented, as this is a prerequisite for claiming after-hours PACS premiums (E406-E408) attached to X415.
