G196
G196 – Hypersensitivity skin test for validated drugs or agents
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
When to Use
- Use G196 when performing a diagnostic skin prick or intradermal test specifically to confirm or rule out a drug hypersensitivity reaction.
- Select G196 for testing validated pharmaceutical agents, such as local anesthetics or antibiotics, where the clinical suspicion of an IgE-mediated reaction exists.
Common Pitfalls
- Claiming G196 for allergy testing related to environmental inhalants or food allergens, which are explicitly excluded from this code's scope.
- Billing E582 in conjunction with G196 for hospital-based procedures, as E582 is strictly limited to non-hospital settings.
Billing Tips
- Ensure the specific drug agent tested is clearly identified in the medical record to support the diagnostic nature of the G196 claim during an audit.
- Always append E582 to your G196 claim when testing with penicillin minor determinant mixture in a community clinic to capture the additional $32.20 fee.
