How To Use CPT Code 50542

CPT 50542 describes the laparoscopic ablation of renal mass lesion(s) using various methods such as cryoablation or radiofrequency. This article will cover the description, official description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information and billing examples.

1. What is CPT Code 50542?

CPT 50542 can be used to describe the laparoscopic ablation of renal mass lesion(s) using methods like cryoablation or radiofrequency. This code is used when the provider destroys the mass lesion(s) via a laparoscopic approach, using imaging guidance and monitoring during the procedure.

2. Official Description

The official description of CPT code 50542 is: ‘Laparoscopy, surgical; ablation of renal mass lesion(s), including intraoperative ultrasound guidance and monitoring, when performed.’

3. Procedure

1. The provider typically makes several small incisions in the abdomen to access the kidney.
2. Using imaging guidance, the provider locates the renal mass lesion(s).
3. If cryoablation is used, the provider inserts a probe containing liquid nitrogen to freeze and destroy the lesion(s).
4. If radiofrequency ablation is used, the provider passes a thin probe into the mass lesion(s) and uses radiofrequency waves to increase the temperature and destroy the tumor.
5. The procedure includes intraoperative ultrasound guidance and monitoring, if used.
6. The provider closes the small incisions with staples or sutures.

4. Qualifying circumstances

CPT 50542 is performed on patients with renal mass lesion(s) that require ablation. The provider uses a laparoscopic approach and may use cryoablation or radiofrequency methods to destroy the lesion(s). Intraoperative ultrasound guidance and monitoring may be used during the procedure.

5. When to use CPT code 50542

CPT code 50542 should be used when a provider performs laparoscopic ablation of renal mass lesion(s) using cryoablation or radiofrequency methods. This code should only be used once per procedure.

6. Documentation requirements

To support a claim for CPT 50542, the provider must document the following information:

• Diagnosis of renal mass lesion(s) and the need for ablation
• Method used for ablation (cryoablation or radiofrequency)
• Date and details of the procedure, including the use of intraoperative ultrasound guidance and monitoring
• Any complications or additional procedures performed
• Signature of the provider performing the procedure

7. Billing guidelines

When billing for CPT 50542, ensure that the procedure is performed using a laparoscopic approach and includes cryoablation or radiofrequency ablation. Intraoperative ultrasound guidance and monitoring should also be documented. Do not report CPT 50542 with other codes for renal ablation procedures. Use CPT code 50541 for surgical laparoscopic ablation of renal cysts.

8. Historical information

CPT 50542 was added to the Current Procedural Terminology system on January 1, 2003. There have been no updates to the code since its addition.
