G197
G197 – Skin testing - professional component
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
The professional component for allergy skin testing. The corresponding technical component is billed under G209. There is a maximum of 50 tests per year per patient.
When to Use
- Use G197 when you are personally interpreting and documenting the results of allergy skin tests performed by staff.
- Apply this code for each individual allergen test interpreted, ensuring the total count does not exceed 50 per patient per year.
Common Pitfalls
- Billing G197 without a corresponding G209 claim for the technical component will trigger an audit flag for incomplete service reporting.
- Submitting claims for more than 50 tests per patient per year will result in automatic rejection by the Ministry.
- Attempting to bill G197 as a standalone service without documented clinical interpretation of the specific allergen reactions is a common cause of recovery.
Billing Tips
- Always bill G197 in conjunction with G209 for every test performed to ensure the full professional and technical service is captured.
- Maintain a log of the specific allergens tested to justify the count of G197 units billed if requested during a post-payment review.
