CPT 32998 Percutaneous RFA Reimbursement

CPT code 32998 represents a percutaneous, unilateral radiofrequency ablation (RFA) procedure used to thermally destroy tumor tissue in the lung, pleura, or chest wall via a minimally invasive needle electrode. This code captures a clinically important image-guided or non-image-guided interventional oncology service that supports lung cancer and chest wall tumor management and is relevant to hospital outpatient departments, ambulatory surgery centers, and interventional radiology practices nationwide. Nationally, accurate coding for percutaneous RFA affects clinical workflow, billing consistency, and payer coverage decisions for interventional oncology.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find guidance on the clinical context of 32998, how the service is typically delivered, and which sites of service are most common. The publication also provides benchmarking context and policy considerations relevant to reimbursement and claims adjudication, plus summaries of common billing nuances where available. Data not available in the input is clearly identified where applicable.

Billing Code Overview

CPT code 32998 describes a percutaneous, unilateral radiofrequency ablation procedure in which a provider inserts a needle electrode into the chest cavity using a minimally invasive approach. The electrode generates thermal energy using radio waves to destroy tumor cells in the lung, pleura, or chest wall. The procedure may be performed with or without imaging guidance.

Service type: Image-guided or non-image-guided percutaneous tumor ablation (radiofrequency ablation), unilateral

Typical site of service: Hospital outpatient department, ambulatory surgery center, or interventional radiology suite

Clinical Context

A 68-year-old patient with a solitary 2.5 cm peripheral non–small cell lung carcinoma in the right lower lobe and significant cardiopulmonary comorbidity is referred for image-guided percutaneous tumor ablation. The patient has already undergone staging with CT chest and PET/CT confirming no distant metastases and is not a candidate for lobectomy due to reduced pulmonary reserve. The interventional pulmonologist or interventional radiologist performs a unilateral percutaneous radiofrequency ablation using a needle electrode introduced through the chest wall into the tumor under CT guidance. Conscious sedation or monitored anesthesia care is provided in a procedure suite or interventional radiology room. Post-procedure, the patient is observed for pneumothorax and pain control; a chest radiograph or CT is obtained to evaluate for complications prior to discharge or admission for overnight observation.
