This service represents the professional component (interpretation and report) of fluorescein angiography. The corresponding technical component is billed separately as G853. Note: For bilateral procedures, add 50% of the listed benefit. This rule also applies to G853, G444, and G854.

When to Use

Use G425 when you are providing the formal interpretation and written report for a fluorescein angiography procedure performed on a patient.
Apply this code when billing for the professional component in conjunction with the technical component G853 performed in the same session.

Common Pitfalls

Failing to append the bilateral modifier (usually 'BI' or equivalent) when interpreting images for both eyes, which results in underpayment of the 50% premium.
Billing G425 without a corresponding G853 technical fee, which may trigger an audit regarding the existence of the technical component documentation.
Attempting to bill G425 alongside a general office visit code (A007) for the same encounter without clear documentation of a separate, distinct clinical assessment.

Billing Tips

Ensure your clinical note explicitly states the interpretation findings to support the professional component claim, as the report is the primary audit requirement for G425.
Always bill G425 and G853 together on the same claim submission to ensure the professional and technical components are reconciled correctly by the Ministry.
