Question: Tennessee Subscriber Answer: Medicare payers will allow reimbursement for 64612 per eye. For example, if the ophthalmologist uses Botox to treat blepharospasm with injections into the skin around one eye, you would use 64612 with modifier LT (Left side) or RT (Right side) on the first line of the CMS-1500 form. If he injects Botox for blepharospasm of the right and left eyelids, report 64612-50 (Bilateral procedure). With payers other than Medicare, you should always use two lines when billing multiple procedures -- so in this case, code 64612-RT and 64612-LT. Report the codes per eye (right or left), not per injection. If the ophthalmologist administers more than one injection on the same side, you may still only report a single billing of 64612. If your office is supplying the drug, don't forget to bill using HCPCS supply code J0585 (Injection, onabotulinumtoxinA, 1 unit). In the past, Medicare reimbursed J0585 as 100 units, but for years it has reimbursed per unit. They will also allow billing for the wasted portion if no other patients are being treated with Botox that day and your patient is the last patient of the day to receive the Botox where an unused portion remains and must be wasted.
