CPT Code 64721 | Description & Clinical Information
CPT 64721 describes the surgical procedure of neuroplasty or transposition of the median nerve at the carpal tunnel, which is performed to alleviate the symptoms of carpal tunnel syndrome (CTS), a condition caused by the compression of the median nerve and nine flexor tendons of the hand that pass through the narrow tunnel in the wrist, resulting in numbness and weakness of the muscles in the hand, and can be caused by various disease conditions or work-related activities that require repetitive finger movements.
Official Description
The CPT book defines CPT code 64721 as: “Neuroplasty and/or transposition; median nerve at carpal tunnel”.
Billing Guidelines
Do not use codes 64716, 64718, 64719, or 64721 together with 11960. All codes mentioned are CPT codes.
To perform an endoscopic procedure, utilize CPT code 29848.
Clinical Information
The procedure describes by CPT code 64721 involves a surgical method to alleviate carpal tunnel syndrome. This condition occurs when the median nerve, which runs through the wrist and into the hand, is compressed due to pressure on the carpal tunnel. The result is pain, numbness, and tingling sensations in the hand and fingers.
To relieve the symptoms, a small incision is made over the carpal tunnel in the palm and wrist. This incision is carefully placed to avoid damaging any vital structures in the hand. Through this incision, the palmar fascia, which is a tough layer of tissue covering the carpal tunnel, is cut. This exposes the carpal ligament, which is then surgically divided.
The surgical division of the carpal ligament aims to release pressure on the median nerve, relieving the symptoms of carpal tunnel syndrome. Throughout the procedure, utmost care is taken to ensure the safety of the median nerve and the tendons surrounding it. Excessive pressure, traction or damage to any of these delicate structures can lead to further nerve damage or loss of hand function.
After the ligament is divided, the incision is closed in layers to promote proper healing. A successful CPT 64721 procedure should result in the relief of carpal tunnel syndrome symptoms, allowing for improved hand function and quality of life.
It is important to note that this procedure is a relatively simple surgery and often performed as an outpatient procedure. The patient is usually prescribed pain medication and referred to physical therapy after the procedure to ensure optimal recovery.
As with any surgical procedure, there are potential risks and complications involved with CPT 64721. These may include infection, bleeding, nerve damage, scarring, and prolonged recovery time. Patients should discuss these risks with their physician prior to the procedure to make an informed decision.
In conclusion, CPT code 64721 describes a surgical procedure used to treat carpal tunnel syndrome. It involves a small incision made in the palm and wrist to access and surgically divide the carpal ligament. Care is taken throughout the procedure to ensure the safety of the median nerve and surrounding structures. Although the procedure carries some risks, it can successfully relieve the symptoms of carpal tunnel syndrome and improve hand function.
