Summary & Overview
CPT 60520: Thymectomy, Resection of Thymus Gland
CPT code 60520 denotes surgical removal of part or all of the thymus gland, most often performed for thymoma or other thymic pathology. As a definitive surgical treatment, this procedure is an important component of thoracic surgical practice and oncology care pathways nationwide. It has implications for hospital resource use, perioperative management, and long-term follow-up for patients with thymic tumors.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a national-level overview of how CPT code 60520 maps to clinical indications and sites of care, alongside expected service-line placement and payer coverage considerations. The publication summarizes common billing practices, lists frequently applied modifiers (input provided), and highlights areas where policy updates or coding clarification typically arise.
The report provides clinical context for when thymectomy is performed, describes typical sites of service (hospital OR and ambulatory surgical centers), and outlines the types of benchmarks and policy issues relevant to stakeholders, including reimbursement patterns, inpatient versus outpatient utilization, and coding specificity needs. Data not available in the input will be identified as such in detailed sections.
Billing Code Overview

-
Service type: Surgical resection of thymus (thymectomy), open or transsternal approach implied by gland removal
-
Typical site of service: Inpatient or outpatient hospital operating room; may also occur in ambulatory surgical centers depending on clinical complexity and surgical approach
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient presents with chest discomfort and imaging that reveals an anterior mediastinal mass suspicious for a thymoma. The thoracic surgery team evaluates the patient with preoperative labs, chest CT, and pulmonary function testing. After multidisciplinary review, the patient is scheduled for surgical resection of the thymus (thymectomy) under general anesthesia. In the operating room, the surgeon performs either a partial or total thymectomy via a median sternotomy, transcervical approach, or minimally invasive thoracoscopic/thoracotomy technique depending on tumor size and location. The procedure includes dissection of thymic tissue from adjacent structures, hemostasis, and placement of drains if needed. Postoperatively the patient is monitored in a post-anesthesia care unit and typically admitted to a surgical ward or ICU for respiratory monitoring and pain control. Pathology evaluation of the specimen confirms tumor type and margins, guiding any adjuvant therapy such as radiation or oncology referral.
