G150 – Visual evoked response - threshold - professional component
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
The professional component of a visual evoked response - threshold test, a diagnostic procedure used in ophthalmology. This code represents the physician's work in interpreting and reporting on the test, which is performed in conjunction with the technical component, G152. As defined in the Schedule, the professional component is a class of service representing the physician's interpretation and is claimed separately from the technical component.
When to Use
- Use G150 specifically to bill for the professional interpretation and reporting of a visual evoked response threshold test.
- Claim G150 only when the technical component of the test has been performed and billed concurrently using G152.
Common Pitfalls
- Billing G150 without a corresponding G152 claim will result in an automatic rejection as the professional component requires the technical component to be present.
- Attempting to bill G150 for a general ophthalmological examination or routine visual field test, which are covered under different diagnostic codes.
Billing Tips
- Ensure the formal written report of the interpretation is finalized and dated, as this is the primary evidence required to support the professional component claim during an audit.
