G427 – Ophthalmodynamometry
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Ophthalmodynamometry is a diagnostic procedure listed under ophthalmology.
When to Use
- Use G427 when performing objective measurement of central retinal artery pressure to evaluate carotid artery insufficiency.
- Use this code when assessing patients for suspected ophthalmic artery occlusion or stenosis where non-invasive pressure measurement is clinically indicated.
Common Pitfalls
- Do not bill G427 in conjunction with a general eye examination code like A025, as the procedure is considered part of the comprehensive assessment.
- Avoid billing G427 if the procedure is performed as a routine screening rather than a diagnostic investigation for a specific symptomatic vascular condition.
Billing Tips
- Ensure the clinical indication for the pressure measurement is clearly linked to a vascular diagnosis to justify the procedure separate from standard diagnostic codes like G424 or G426.
