How To Use CPT Code 0442T

CPT 0442T describes a percutaneous cryoablation procedure that involves the destruction of a nerve plexus or other truncal nerve using freezing temperatures. This article will cover the official description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, and examples of CPT code 0442T.

1. What is CPT Code 0442T?

CPT 0442T can be used to describe a percutaneous cryoablation procedure that involves the destruction of a nerve plexus or other truncal nerve using freezing temperatures. This code is used when a healthcare provider performs the procedure to treat complex regional pain syndrome or other neuropathy.

2. Official Description

The official description of CPT code 0442T is: ‘Ablation, percutaneous, cryoablation, includes imaging guidance; nerve plexus or other truncal nerve (eg, brachial plexus, pudendal nerve)’

3. Procedure

1. The healthcare provider begins by prepping and anesthetizing the patient, typically with moderate sedation.
2. After localizing the area to be treated, the provider injects lidocaine to provide local anesthesia.
3. A small skin incision is made over the area to be treated.
4. Using imaging guidance, the provider inserts a special cryoablation needle down to the nerve.
5. Through the needle, an “ice ball” is delivered to destroy (ablate) the nerve.
6. The provider may follow a freeze-thaw, freeze-thaw protocol.
7. Once satisfied that the nerve has been destroyed, the needle is removed and the small incision is closed.

4. Qualifying circumstances

CPT 0442T is used for patients with complex regional pain syndrome or other neuropathy who require the destruction of a nerve plexus or other truncal nerve. The procedure is performed by a healthcare provider using cryoablation, which involves the application of freezing temperatures. The nerve plexus or truncal nerve can be located in the trunk of the body or the genital area (pudendum).

5. When to use CPT code 0442T

CPT code 0442T should be used when a healthcare provider performs a percutaneous cryoablation procedure to destroy a nerve plexus or other truncal nerve using freezing temperatures. This code should be used specifically for the ablation of the nerve, and not for other procedures or services provided during the same encounter.

6. Documentation requirements

To support a claim for CPT 0442T, the healthcare provider must document the following information:

• Patient’s diagnosis of complex regional pain syndrome or other neuropathy
• Specific nerve plexus or truncal nerve targeted for ablation
• Date of the procedure
• Details of the procedure, including the use of imaging guidance
• Any complications or adverse events that occurred during or after the procedure
• Signature of the healthcare provider performing the procedure

7. Billing guidelines

When billing for CPT 0442T, ensure that the procedure is performed by a qualified healthcare provider and includes imaging guidance. Do not report the imaging guidance service separately. It is important to note that CPT code 0442T should not be reported if other specific codes (CPT 0444T to CPT 0465T) have already been performed within the previous seven days. Additionally, consider the location of the testing when coding for pulmonary function tests, as they have both a professional and technical component.

8. Historical information

CPT 0442T was added to the Current Procedural Terminology system on July 1, 2016. There have been no updates to the code since its addition.

9. Examples

1. A healthcare provider performs a percutaneous cryoablation procedure to destroy a nerve plexus in the brachial plexus of a patient with complex regional pain syndrome.
2. Using freezing temperatures, a provider performs a percutaneous cryoablation procedure to ablate a truncal nerve in the pudendal area of a patient with neuropathy.
3. A healthcare provider utilizes cryoablation to destroy a nerve plexus in the trunk of a patient with complex regional pain syndrome.
4. Performing a percutaneous cryoablation procedure, a provider targets a truncal nerve in the brachial plexus of a patient with neuropathy.
5. A patient with complex regional pain syndrome undergoes a percutaneous cryoablation procedure to destroy a nerve plexus in the pudendal area.
6. Using freezing temperatures, a provider performs a percutaneous cryoablation procedure to ablate a truncal nerve in the trunk of a patient with neuropathy.
7. A healthcare provider utilizes cryoablation to destroy a nerve plexus in the brachial plexus of a patient with complex regional pain syndrome.
8. Performing a percutaneous cryoablation procedure, a provider targets a truncal nerve in the pudendal area of a patient with neuropathy.
9. A patient with complex regional pain syndrome undergoes a percutaneous cryoablation procedure to destroy a nerve plexus in the trunk of the body.
10. Using freezing temperatures, a provider performs a percutaneous cryoablation procedure to ablate a truncal nerve in the brachial plexus of a patient with neuropathy.
