Chemodenervation of laryngeal muscle(s), unilateral, percutaneous, with needle electromyography guidance.
Modifier 50 is applicable for bilateral procedures.
Medical necessity should be established by documenting the diagnosis causing laryngeal muscle dysfunction and the impact of this dysfunction on the patient's voice, breathing, or swallowing. The medical record should also demonstrate that less invasive treatments have been tried or are not appropriate.
The physician injects a chemodenervation agent, such as botulinum toxin, into the larynx to treat conditions like spasmodic dysphonia. Needle electromyography is used to guide the injection.
In simple words: This procedure involves injecting medicine into the larynx (voice box) on one side to treat muscle spasms.A small needle is inserted through the skin, and the injection is guided by electromyography (EMG) to ensure precise placement of the medicine.
Chemodenervation of muscle(s); larynx, unilateral, percutaneous (e.g., for spasmodic dysphonia), includes guidance by needle electromyography, when performed.
Example 1: A patient with spasmodic dysphonia receives a unilateral injection of botulinum toxin into the laryngeal muscles, guided by needle electromyography., A patient with vocal tremor undergoes chemodenervation of the laryngeal muscles on one side using EMG guidance for precise targeting., A patient with laryngeal dystonia receives a percutaneous injection of botulinum toxin into the affected laryngeal muscles on one side, with the procedure guided by needle electromyography.
Documentation should include the diagnosis, the specific laryngeal muscles injected, the chemodenervation agent used, the use of needle electromyography guidance, and the response to the procedure.
