Question: I have a Medicare patient that one of our surgeons injected with Botox for spasmodic dysphonia. He billed out CPT® code 64613, which I believe is an incorrect code since he did this procedure with a flexible laryngoscope and injected the Botox in that manner. What’s the correct way to code the procedure?
Answer: Begin with the correct diagnosis of 478.79 (Other diseases of larynx) for spasmodic dysphonia.

You are correct that the physician is incorrectly planning to bill 64613 (Chemodenervation of muscle[s]; neck muscle[s] [e.g., for spasmodic torticollis, spasmodic dysphonia]) for the procedure.64613 is used if the Botox is injected into the larynx via a percutaneous approach. Because he used a laryngoscope for visualization and injection administration, the appropriate choice is 31570 (Laryngoscopy, direct, with injection into vocal cord[s], therapeutic). Also report J0585 (Injection, Onabotulinumtoxina, 1 unit) on a separate line with a notation of the number of units injected. On a third line, report J0585 with the number of units wasted.
