X173
X173 – Myelogram - spine and/or posterior fossa
OHIP Laboratory Code — DIAGNOSTIC RADIOLOGY · Schedule of Benefits
A diagnostic imaging procedure that involves the injection of a contrast medium into the spinal canal to visualize the spinal cord, nerve roots, and surrounding structures via X-ray. The fee is divided into a technical component (H) of $34.95 and a professional component (P) of $27.30. Per :, the technical component is claimed with suffix B (e.g., X173B) and the professional component with suffix C (e.g., X173C).
When to Use
- Use X173C when providing the professional interpretation of a myelogram for spinal cord or nerve root visualization.
- Use X173B when billing for the technical facility component of the myelogram procedure performed in an eligible hospital setting.
Common Pitfalls
- Submitting X173 without a suffix will result in an automatic rejection; you must split the claim into X173B and X173C.
- Billing X173C in a private clinic setting is ineligible for the professional fee component if the facility does not meet hospital-based diagnostic requirements.
- Attempting to bill X173 alongside other diagnostic imaging codes for the same anatomical region without clear clinical justification may trigger a manual audit for unbundling.
Billing Tips
- If performing this procedure on an urgent basis in a hospital on a weekend, ensure you append the C110 premium to the professional component (X173C) to capture the special visit fee.
