G201
G201 – Direct nasal tests
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Direct nasal tests, to a maximum of 3 per year (per test)
When to Use
- Use G201 when performing a direct nasal smear or diagnostic test specifically for allergic rhinitis or related nasal pathology.
- Use this code when the diagnostic procedure is distinct from a standard office assessment, keeping in mind the annual limit of 3 services per patient.
Common Pitfalls
- Billing G201 more than 3 times per year for the same patient will trigger an automatic rejection or recovery during audit.
- Attempting to bill G201 in conjunction with a full office assessment code (like A007) without clear documentation of a separate, medically necessary diagnostic procedure often leads to claim rejection.
Billing Tips
- Ensure the clinical note explicitly details the nasal testing procedure performed to justify the G201 fee separate from any concurrent allergy injection or assessment codes.
