Summary & Overview
CPT 33050: Pericardial Tumor or Cyst Excision
CPT code 33050 covers surgical excision of a tumor or cyst from the pericardium, the fibrous membrane surrounding the heart. This code captures a specialized cardiothoracic surgical procedure that carries clinical importance due to potential impacts on cardiac function and the need for perioperative cardiac care. Nationally, accurate coding for pericardial tumor or cyst excision informs utilization tracking, resource planning for cardiothoracic services, and payment for complex inpatient procedures.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for this surgical service, typical sites of care, and which major payers are relevant to coverage and reimbursement discussions. The publication highlights benchmarks where available, common billing considerations, and policy or coding updates that affect claim submission and medical necessity documentation. It also situates CPT code 33050 within broader cardiothoracic surgical service lines to help billing, coding, and revenue cycle teams ensure accurate capture of pericardial lesion excisions.
Data not available in the input is identified where specific payer rate benchmarks, associated taxonomies, related codes, and ICD-10 diagnosis mappings are not provided.

Clinical & Coding Specifications
Clinical Context
A 58-year-old patient presents with progressive dyspnea, chest discomfort, and imaging evidence of a pericardial mass identified on transthoracic echocardiography and confirmed by contrast-enhanced chest CT. The cardiothoracic surgery team evaluates the patient and determines that surgical excision of a pericardial cyst/tumor is indicated due to symptomatic compression of cardiac chambers and risk of malignant transformation. The patient is admitted to an inpatient surgical unit. Preoperative workflow includes history and physical, cardiology clearance, baseline labs, electrocardiogram, and anesthesia evaluation. Intraoperative management is performed in a cardiac operating room under general endotracheal anesthesia with invasive monitoring. A median sternotomy or subxiphoid approach is used based on tumor location; the pericardium is opened, the lesion is identified, resected, and hemostasis achieved. Specimens are sent for pathology. Postoperative care occurs in a cardiothoracic recovery area or intensive care unit with monitoring for arrhythmia, bleeding, pericardial effusion, and hemodynamic stability. Discharge planning includes wound care, activity restrictions, follow-up with cardiothoracic surgery, and pathology review.
