A diagnostic radiology examination of the oesophagus, stomach, and small bowel. This service has a technical component (Fee H: $59.10) and a professional component (Fee P: $49.80). The professional component covers the interpretation and report. The technical component covers the cost of equipment, supplies, and personnel. See for rules regarding the eligibility of technical and professional components.

When to Use

Use X109 when a comprehensive diagnostic study of the entire upper gastrointestinal tract, including the small bowel, is performed in a single session.
Use X109 when the clinical indication requires a small bowel follow-through in addition to the standard oesophagus and stomach examination, as it replaces the need for separate, restricted codes like X103 or X104.

Common Pitfalls

Billing X109 in combination with X103, X104, X107, or X108 will trigger an automatic rejection due to mutual exclusivity rules.
Attempting to bill X109 for services rendered via PACS or outside of a hospital setting will result in the denial of associated special visit premiums like C102, C103, or C104.

Billing Tips

Ensure the referral explicitly supports the necessity of the small bowel component to justify the use of X109 over more limited upper GI codes.
When billing for non-elective, urgent hospital-based interpretations, ensure the claim includes the appropriate special visit premium (e.g., C108, C110) to maximize the professional component value.
