How To Use CPT Code 64704

CPT 64704 describes a procedure known as neuroplasty, which involves the exploration, neurolysis, or nerve decompression of extracranial nerves, peripheral nerves, and the autonomic nervous system. This article will cover the official description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information and billing examples.

1. What is CPT Code 64704?

CPT 64704 is a code used to describe a surgical procedure called neuroplasty. This procedure involves the exploration, neurolysis, or nerve decompression of extracranial nerves, peripheral nerves, and the autonomic nervous system. It is performed to relieve tension on a nerve in the hand or foot by incising scar tissue or other sources of pressure. The nerves in the hand or foot include both sensory and motor nerves that innervate the back and palm of the hand.

2. Official Description

The official description of CPT code 64704 is: ‘Neuroplasty; nerve of hand or foot.’

3. Procedure

1. The provider begins by appropriately prepping and anesthetizing the patient.
2. An incision is made into the target site in the patient’s hand or foot where the compressed nerve is located.
3. The provider then locates the compressed nerve and performs external neurolysis, which involves removing the surrounding scarring from the nerve without entering into the nerve.
4. If necessary, the provider may also remove any bone spur or damaged muscle that is putting pressure on the nerve.
5. Once the nerve is freed and repaired, the provider closes the incision in layers.

4. Qualifying circumstances

CPT 64704 is performed on patients who have a compressed nerve in their hand or foot that requires exploration, neurolysis, or nerve decompression. The procedure is typically done to relieve tension on the nerve caused by scar tissue or other sources of pressure. It is important to note that CPT code 64704 should not be reported in conjunction with CPT code 11960.

5. When to use CPT code 64704

CPT code 64704 should be used when a provider performs neuroplasty on a nerve in the hand or foot. It is appropriate to use this code when the procedure involves the exploration, neurolysis, or nerve decompression of extracranial nerves, peripheral nerves, or the autonomic nervous system. However, it should not be reported with CPT code 11960.

6. Documentation requirements

To support a claim for CPT 64704, the provider must document the following information:

• Patient’s diagnosis and the need for neuroplasty
• Specific details of the procedure performed, including the location of the compressed nerve
• Incision site and closure method
• Any additional procedures performed, such as the removal of bone spurs or damaged muscle
• Signature of the provider performing the procedure

7. Billing guidelines

When billing for CPT 64704, ensure that the procedure involves the exploration, neurolysis, or nerve decompression of a nerve in the hand or foot. It should not be reported in conjunction with CPT code 11960. Additionally, consider the location of the testing, as it may affect how the procedure is coded.

8. Historical information

CPT 64704 was added to the Current Procedural Terminology system on January 1, 1990. There have been no updates to the code since its addition.

9. Examples

1. A provider performs neuroplasty on a compressed nerve in a patient’s hand to relieve tension and improve function.
2. A patient presents with foot pain caused by a compressed nerve, and the provider performs neuroplasty to alleviate the pressure and restore mobility.
3. A provider performs neuroplasty on a nerve in the hand of a patient with carpal tunnel syndrome to relieve symptoms and improve hand function.
4. A patient with chronic foot pain undergoes neuroplasty to decompress a nerve and alleviate discomfort.
5. A provider performs neuroplasty on a compressed nerve in a patient’s hand to improve sensation and motor function.
6. A patient with peripheral neuropathy undergoes neuroplasty to relieve pain and restore nerve function in the foot.
7. A provider performs neuroplasty on a compressed nerve in a patient’s hand to alleviate symptoms of tingling and numbness.
8. A patient with a history of foot trauma undergoes neuroplasty to release a compressed nerve and improve foot function.
9. A provider performs neuroplasty on a nerve in the hand of a patient with cubital tunnel syndrome to relieve symptoms and restore hand function.
10. A patient with chronic hand pain undergoes neuroplasty to decompress a nerve and alleviate discomfort.
