G332 – Capsule endoscopy
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Capsule endoscopy is a diagnostic procedure. The specific payment rule regarding 'identifying gastrointestinal bleeding of obscure origin' is not found on the referenced page (page 446) or elsewhere in the Schedule of Benefits. G332 does not have a '#' prefix on page , making the related description about hospital funding inapplicable.
When to Use
- Use G332 when performing a capsule endoscopy to investigate suspected small bowel pathology that remains undiagnosed after standard upper and lower endoscopy.
- Bill G332 for the diagnostic interpretation of the images captured during the procedure, ensuring the service is performed within an appropriate clinical setting.
Common Pitfalls
- Do not bill G332 in conjunction with other diagnostic imaging codes for the same anatomical region if the Schedule of Benefits explicitly restricts concurrent billing.
- Avoid billing G332 if the procedure is performed as part of a research protocol or for non-insured indications, as these are not eligible for OHIP reimbursement.
Billing Tips
- Since G332 lacks the '#' prefix, ensure you are not incorrectly applying hospital-based funding modifiers that are reserved for codes designated with that symbol.
