Answer: Report CPT code 64612-51 (Chemodenervation of muscle[s]; muscle[s] innervated by facial nerve [e.g., for blepharospasm, hemifacial spasm]; multiple procedures) for the Botox injections. Don't use an unlisted-procedure code, since there is a more appropriate code to use for the injections.
For the Botox supply, bill HCPCS code J0585 (Botulinim toxin type A, per unit). Use the proper ICD-9 diagnosis code from the 370.0x series (Corneal ulcer).
Most important: Your carrier may not cover the Botox injections for this purpose. Get Medicare patients to sign an advance beneficiary notice prior to the procedure. If the patient has other insurance, contact them in advance to see if they'll cover the procedure - and get it in writing. Botox is an expensive drug to use for what may turn out to be a noncovered diagnosis and procedure.
