G002 – Glucose, quantitative or semi-quantitative
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Performs a quantitative or semi-quantitative glucose test. As per , this is classified as a 'simple office laboratory procedure'. Under the rules for delegated procedures on page , this service may be performed by a physician's employee, and the physician is not required to be physically present if certain conditions are met. This service is also listed as a component of the W010 Monthly Management of a Nursing Home or Home for the Aged Patient fee and is therefore not separately payable when W010 is billed ().
When to Use
- Use G002 when performing an in-office point-of-care glucose test for a patient presenting with acute symptoms of hypoglycemia or hyperglycemia.
- Bill this code for routine glucose monitoring during a standard office visit when it is not bundled into a comprehensive management fee like W010.
Common Pitfalls
- Billing G002 on the same day as a counselling code (e.g., K013, K040) will result in an automatic rejection, as it is not an exempt diagnostic procedure.
- Submitting G002 for a patient under W010 management will trigger a rejection because the laboratory fee is already included in the monthly nursing home management payment.
Billing Tips
- Ensure your billing software flags G002 as non-payable if any counselling code is present on the same claim to avoid unnecessary audit triggers.
- Since G002 is a delegated procedure, ensure your office documentation clearly identifies the staff member who performed the test if the physician was not physically present.
