Billing for 2 Shunts in the Same Eye
Question: The payer denied CPT code 66185 Revision of aqueous shunt to extraocular equatorial plate reservoir; with graft when billed on separate lines for both superior and inferior tubes in the right eye. Should we have submitted with modifier -50 instead?
Answer: Payment is per eye, not per tube. You can attempt to submit with modifier -22 and go to review to request additional payment for this unusual case if you choose to do so.
