G206 – Patch test
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
maximum of 90 per patient, per year (per test)
When to Use
- Use G206 for each individual patch test applied during a diagnostic series, up to a maximum of 90 units per patient per year.
- Bill G206 when performing formal contact dermatitis investigations where multiple allergens are applied to the skin surface for delayed hypersensitivity assessment.
Common Pitfalls
- Do not bill G206 in conjunction with G198 on the same day for the same patient, as G198 covers the administration of allergenic extracts and is distinct from patch testing.
- Exceeding the annual limit of 90 units per patient will result in automatic rejection; track cumulative totals carefully to avoid billing beyond the cap.
Billing Tips
- Ensure the total number of patches applied is clearly documented in the chart to support the specific number of G206 units claimed on the day of service.

Procedure
Diagnostic and Therapeutic Procedures
If a patient presents for an allergy injection and has an acute infectious condition, albeit of the respiratory system, or some other unrelated condition which would have otherwise required a separate office visit, the physician is entitled to claim the appropriate assessment fee as well as the injection fee. If a patient requires a brief assessment of his allergic condition as well as the allergy injection, the physician should claim the injection and the basic fee, in which case the specific elements of the service include those of an assessment (see General Preamble ).
