Summary & Overview

CPT 60522: Thymectomy via Sternotomy or Thoracotomy

CPT code 60522 denotes partial or complete thymectomy performed via a median sternotomy or unilateral/bilateral thoracotomy and may include removal of adjacent mediastinal structures. This thoracic surgical code is used for management of thymic tumors, myasthenia gravis when indicated, and other mediastinal pathologies requiring open resection. Nationally, accurate coding for major thoracic procedures like this affects hospital claims processing, DRG assignment, and aggregated utilization metrics for cardiothoracic surgery.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for open thymectomy, typical sites of service and procedural setting, and the primary payer landscape. The publication highlights billing benchmarks, common payer considerations, and relevant policy updates that influence coverage and claims adjudication for major thoracic procedures. It also outlines implications for hospital service-line planning and surgical resource allocation. Where specific payer-level data or related coding details are not provided in the input, the report notes that such data are not available.

Billing Code Overview

CPT code 60522 describes surgical removal of the thymus gland, either partially or completely, performed through an incision in the sternum (sternotomy) or via one or both sides of the chest (thoracotomy). The procedure may include excision of adjacent mediastinal tissues when necessary to achieve complete resection.

Service type: Surgical resection of thymus (open thoracic surgery)
Typical site of service: Inpatient or outpatient hospital surgical setting, operating room (thoracic surgery service)

Clinical & Coding Specifications

Clinical Context

A typical patient is a 45–65-year-old adult referred for surgical management of a thymic mass (such as a thymoma) or for symptomatic myasthenia gravis unresponsive to medical therapy. The patient presents after cross-sectional imaging (CT or MRI) demonstrating an anterior mediastinal lesion centered in the thymic bed. Preoperative evaluation includes neurology assessment if autoimmune disease is present, pulmonary function testing, cardiopulmonary clearance, and blood typing. The operative plan calls for removal of the thymus gland via a median sternotomy or unilateral/bilateral thoracotomy depending on tumor size and invasion. Intraoperatively the thoracic surgeon performs en bloc resection of the thymus with adjacent mediastinal tissue as indicated; specimens are sent for permanent pathology. Postoperative care includes ICU or step-down monitoring for respiratory compromise, pain control, chest tube management if placed, and follow-up imaging and neurology evaluation. Typical sites of service are an inpatient operating room within a hospital setting, with recovery in post-anesthesia care unit and possible ICU admission for complex resections.

`G70.00`	Myasthenia gravis without (acute) exacerbation	Thymectomy is indicated in many patients with generalized myasthenia gravis to improve symptoms and reduce medication needs.
