X110 – Hypotonic duodenogram
OHIP Laboratory Code — DIAGNOSTIC RADIOLOGY · Schedule of Benefits
Hypotonic duodenogram is a diagnostic radiology procedure involving the gastrointestinal tract, as detailed on page of the Schedule. This service is structured with separate technical (H) and professional (P) components. The technical component covers the facility's costs, while the professional component is for the physician's interpretation. General rules for billing diagnostic services are found in the General Preamble on page .
When to Use
- Use X110 specifically for the radiological examination of the duodenum using a hypotonic agent to induce duodenal atony, distinguishing it from standard upper GI series codes like X103.
- Apply this code when the procedure is performed as a dedicated diagnostic study to evaluate duodenal pathology, such as suspected malignancy or inflammatory processes, rather than as part of a routine barium meal.
Common Pitfalls
- Billing X110 without a valid referral from an authorized source (Physician, Nurse Practitioner, or Oral Maxillofacial Surgeon) as required by GP111.
- Attempting to bill the technical component (H fee) as a physician; this component is reserved for the facility, while the physician should only claim the professional component (P fee).
Billing Tips
- Ensure the claim is submitted with the appropriate suffix (C for professional component) to avoid rejection when the fee schedule does not provide separate H and P fee codes.
- If the procedure is performed on an emergency basis after hours, ensure you select the correct Special Visit Premium (C102-C110) rather than attempting to add after-hours premiums to the base code if they are mutually exclusive.
