CPT Code 64617 | Description & Clinical Information

CPT 64617 describes the medical procedure in which the healthcare provider administers percutaneous chemodenervation to the larynx on one side, which can be guided by needle electromyography.

Official Description

The CPT book defines CPT code 64617 as: “Chemodenervation of muscle(s); larynx, unilateral, percutaneous (eg, for spasmodic dysphonia), includes guidance by needle electromyography, when performed”.

Billing Guidelines

Report 64617 as CPT code with modifier 50 for procedures performed bilaterally.

Do not bill for 64617 along with 95873 or 95874.

Use CPT code 95865 for electromyography of the larynx using a diagnostic needle.

To find the CPT codes for chemodenervation of the larynx with direct laryngoscopy, refer to 31570 and 31571.

Clinical Information

The procedure described by CPT code 64617 involves chemodenervation, a medical technique in which a pharmacologic compound, such as botulinum toxin, is injected into the body. This is done via a needle inserted through the skin to interrupt nerve signals and paralyze a muscle or group of muscles controlling the larynx, which is also known as the voice box. The larynx is an important part of the respiratory system as it produces the voice and helps in swallowing and breathing.

During the chemodenervation procedure, the provider may guide the injection using a needle electromyography technique. This helps to isolate the muscles that need to be paralyzed and assess the results of the procedure.

One of the primary uses of the CPT 64617 procedure is to treat spasmodic dysphonia. This is a medical condition that causes involuntary spasms in the muscles of the larynx, resulting in disruptions to voice production. Spasmodic dysphonia can lead to significant social and occupational limitations for those affected.

The chemodenervation procedure can provide relief by paralyzing the muscles responsible for spasmodic dysphonia. This can help to reduce voice disruptions and improve communication for individuals living with this condition.

It is important to note that like all medical procedures, the CPT 64617 carries certain risks. Patients may experience adverse effects such as difficulty swallowing, speech problems, and muscle weakness. It is essential for individuals considering this procedure to consult with their healthcare provider to determine if it is a suitable treatment option for their unique needs.

In conclusion, the CPT 64617 procedure involves chemodenervation, which is a medical technique used to interrupt nerve signals and paralyze muscles in the larynx. This procedure is typically used to treat spasmodic dysphonia, a condition that causes voice disruptions. While it can provide relief, it is important to be aware of the risks and to consult with a healthcare provider to determine if this is the best treatment option.

Return to all the CPT codes for destruction by neurolytic agent (eg, chemical, thermal, electrical or radiofrequency) procedures on the somatic nerves.
