G495 – Glucagon test - (Type B)
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Glucagon test (Type B) for hypertension, pheochromocytoma and insulinoma provocative test (including cold pressor test).
When to Use
- Use G495 when performing a provocative test specifically for the investigation of pheochromocytoma or insulinoma, which distinguishes it from the more general diagnostic procedures covered under G494.
- Apply this code when conducting a cold pressor test as part of a cardiovascular assessment for hypertension, as the code explicitly includes this specific diagnostic maneuver.
Common Pitfalls
- Billing G495 in conjunction with a standard office visit (A007) is often flagged for audit if the documentation does not clearly delineate the time and resources spent on the provocative test versus the consultation.
- Submitting G495 without documenting the specific provocative agent or the physiological response observed during the test will lead to automatic rejection during manual review.
Billing Tips
- Ensure the clinical indication for the provocative test is clearly linked to the diagnosis of pheochromocytoma or insulinoma in the claim record to justify the higher complexity compared to routine diagnostic codes.
