X404 – CT Neck - with IV contrast
OHIP Laboratory Code — DIAGNOSTIC RADIOLOGY · Schedule of Benefits
Computed Tomography (CT) of the neck, with IV contrast. This service falls under the Diagnostic Radiology section of the Schedule of Benefits.
When to Use
- Use X404 specifically when a CT neck is performed with IV contrast; do not use X403, which is the code for a CT neck without contrast.
- Use this code for diagnostic imaging of the neck structures where contrast enhancement is clinically required to differentiate vascular structures, lymphadenopathy, or masses from surrounding tissues.
Common Pitfalls
- Billing X404 for a scan performed without IV contrast, which constitutes an incorrect service code and risks audit recovery.
- Attempting to bill the technical component of X404 for a hospital inpatient, which is prohibited under the Schedule of Benefits as the technical fee is included in the hospital global budget.
Billing Tips
- Ensure the referral documentation clearly specifies the necessity of contrast to support the use of X404 over X403.
- If performing this service as an urgent, non-elective hospital visit after hours, ensure you select the appropriate special visit premium (C109, C108, or C110) rather than attempting to add procedural premiums to the base code.
