CPT 39200 Mediastinal Cyst Excision Reimbursement

CPT code 39200 represents surgical excision of a mediastinal cyst accessed through an incision in the thorax or median sternum. This is a definitive operative procedure performed by thoracic or cardiothoracic surgeons to inspect mediastinal structures and remove cystic pathology. Nationally, the code is relevant for hospital-based surgical billing, perioperative resource allocation, and coding compliance for complex chest procedures. Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will gain a concise clinical and billing orientation to CPT code 39200, including the clinical context of mediastinal cyst removal, typical sites of service (inpatient hospital and operating room), and the types of surgical teams involved. The publication outlines billing benchmarks and common modifier usage where available, highlights payer coverage considerations, and summarizes policy and documentation elements that commonly affect medical necessity determinations and claim adjudication. Data not available in the input is noted where applicable. The goal is to provide clinicians, coding staff, and revenue cycle professionals a clear reference for the clinical intent and billing context of CPT code 39200 for national application.

Billing Code Overview

CPT code 39200 describes a surgical procedure in which the provider gains access to the mediastinum by incising the thorax or the sternum (breastbone), inspects the mediastinal structures, and removes a cyst. This procedure is a mediastinal cyst excision via thoracotomy or median sternotomy.

Service Type: Surgical — Thoracic/Thoracic-Cardiac Surgery

Typical Site of Service: Inpatient hospital or operating room

Clinical Context

A 45-year-old patient presents with progressive anterior chest pressure and imaging that identifies a symptomatic mediastinal cyst. After multidisciplinary evaluation, the cardiothoracic surgical team schedules an operative excision. The typical workflow begins with preoperative evaluation (history, focused cardiopulmonary exam, chest CT or MRI confirming location and size of the cyst, and anesthesia assessment). On the day of surgery the patient undergoes general endotracheal anesthesia. The provider gains access to the mediastinum by a median sternotomy or anterolateral thoracotomy depending on cyst location and extent, inspects the mediastinum, isolates the cyst from adjacent structures (pericardium, great vessels, trachea, esophagus), and performs complete excision of the cyst with hemostasis. Intraoperative adjuncts may include chest tube placement and intraoperative pathology (frozen section). Postoperative care includes ICU or PACU monitoring for airway, hemodynamic stability, chest tube management, pain control, and follow-up imaging and pathology review prior to discharge.

`D36.5`	Neoplasm of uncertain behavior of mediastinum	Used when behavior is uncertain preoperatively and excision is required for diagnosis.
`J98.89`	Other specified respiratory disorders	May be used when nonspecific mediastinal mass causes compressive respiratory symptoms and specific diagnosis pending.
`R07.9`	Chest pain, unspecified	Symptom-based code when chest pain prompts imaging and subsequent cyst excision.
`R09.1`	Pleurisy	Used when pleural irritation or associated pleural disease accompanies mediastinal lesions.
`I26.9`	Pulmonary embolism without acute cor pulmonale	Listed when preoperative workup must exclude thromboembolic disease that can complicate thoracic surgery (coexisting condition).
