A241 OHIP Billing Code: Optometrist-Requested Neuro-Ophthalmic Assessment

The A241 billing code applies to assessments for neuro-ophthalmic disorders requested by optometrists and performed by fellowship-trained neuro-ophthalmologists. These assessments assist in diagnosing and managing complex visual and systemic neurological issues that may impact vision. Typical cases include optometrist referrals for concerns such as disc swelling, afferent pupillary defects, or unexplained visual field loss.

Despite its utility, this code is often underutilized due to stringent documentation requirements and restrictions on eligible practitioners. It is crucial for practitioners to comply with these criteria to ensure proper billing and payment.
