X113 – Colon - air contrast
OHIP Laboratory Code — DIAGNOSTIC RADIOLOGY · Schedule of Benefits
An air contrast barium enema is a diagnostic radiology procedure for examining the colon, listed under the Gastrointestinal Tract sub-section. The service, which can be a primary or secondary study, includes any survey films taken as part of the examination. As a diagnostic service, it is composed of a technical component (H-fee) and a professional component (P-fee), which are billed separately. See for listing. Description from SOB: - air contrast, primary or secondary, including survey films, if taken.
When to Use
- Use X113 specifically for double-contrast barium enema studies where both barium and air are utilized to visualize the colonic mucosa.
- Select X113 for diagnostic imaging of the colon when a single-contrast study (X112) is insufficient for the clinical diagnostic requirements.
Common Pitfalls
- Billing X113 without ensuring the technical component (H-fee) and professional component (P-fee) are submitted separately as required by the Schedule of Benefits.
- Failing to include the mandatory survey films in the claim, as these are considered bundled into the X113 fee and cannot be billed as additional X-ray codes.
Billing Tips
- Ensure the referral source is clearly documented in the patient record, as X113 requires a valid referral from a physician, nurse practitioner, or oral maxillofacial surgeon.
