2025 Thyroid Radiofrequency Ablation CPT Code
Bryant Schmitz • Updated Jul 31, 2025 • 70 hits
Thyroid radiofrequency ablation (RFA) is reported using CPT codes 60660 and +60661. These codes are used by endocrine surgeons, interventional radiologists, and other trained providers to describe thermal ablation of benign thyroid nodules. The procedure is typically performed under ultrasound guidance and helps reduce nodule volume without surgery. This article outlines proper coding practices for thyroid RFA to support accurate billing and reimbursement.

CPT Code for Thyroid Radiofrequency Ablation
The primary CPT code for thyroid RFA is 60660, which covers ablation of a single lobe or the thyroid isthmus. When additional lobes are treated during the same session, add-on code +60661 should also be reported.

Detailed Description of CPT Code 60660
• CPT Code: 60660
• Code Description: Ablation, one or more non-malignant thyroid nodules, unilateral lobe or isthmus, percutaneous, using radiofrequency
• Inclusions: Pre-procedural imaging, ultrasound guidance, percutaneous probe insertion, energy delivery, and post-ablation assessment
• Exclusions: Ablation of additional lobes (billed with +60661), general anesthesia, and separate diagnostic ultrasound studies
Coding & Billing Considerations
• Use 60660 for ablation of one thyroid lobe or the isthmus.
• Report +60661 in addition to 60660 when more than one lobe is treated.
• Do not report these codes for malignant nodules; use other appropriate CPT codes.
• Document ultrasound guidance clearly, though it is considered included in the code.
• Ensure that medical necessity is established in the patient's record for insurance coverage.
• Modifier use is generally unnecessary unless bilateral procedures are distinct and separate.
• Facilities may need to report associated supplies and equipment separately for reimbursement.
Why Proper Coding Is Important
Accurate coding of thyroid radiofrequency ablation ensures appropriate reimbursement and reduces the risk of claim denials. Correct CPT code selection reflects the scope and complexity of the procedure, facilitating proper documentation and compliance. It also supports clarity when communicating with payers and enhances revenue cycle management for outpatient interventional procedures.
What is a CPT Code?
CPT stands for Current Procedural Terminology. These codes are used by medical professionals to describe procedures and services performed. CPT codes are crucial for the billing process, allowing healthcare providers to communicate with insurance companies and other payers about the procedures performed.
