Ophthalmology and Optometry Coding Alert

Question: We have a patient with a corneal ulcer and herpes zoster. To help the healing process, the ophthalmologist plans to perform tarsorrhaphy, using Botox to get the lid to droop over the bandage lens he applied. Any ideas on how I would report this? Should I use the unlisted-procedure code?

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.
