G352 – Biliary tract provocative test with cholecystokinin
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Biliary tract provocative test with cholecystokinin.
When to Use
- Use G352 when performing a cholecystokinin (CCK) provocation test to reproduce biliary-type pain in patients with suspected sphincter of Oddi dysfunction.
- Select G352 specifically for the administration and monitoring of the provocative agent during a biliary diagnostic procedure, distinct from the imaging component covered by radiology codes.
Common Pitfalls
- Billing G352 alongside a standard office assessment (A007) or consultation (A005) will trigger an automatic rejection due to the restriction on concurrent assessment codes.
- Failing to distinguish this procedure from general diagnostic imaging codes like G355 or G356, which cover different biliary diagnostic interventions, often leads to claim denials.
Billing Tips
- Ensure the claim includes the specific diagnostic indication for the provocative test to avoid audit flags regarding the medical necessity of the CCK administration.
- Apply applicable Special Visit Premiums (Tables I-X) if the test is performed outside of standard office hours or in an emergency setting, as G352 is eligible for these add-ons.
