Official Description

Thoracoscopy, surgical; with excision of pericardial cyst, tumor, or mass

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 32661 involves a surgical thoracoscopy, which is a minimally invasive technique used to access the thoracic cavity. This procedure is specifically performed to excise a pericardial cyst, tumor, or mass. The pericardium is a protective fibrous membrane that encases the heart, and the presence of a cyst, tumor, or mass can lead to various complications, including cardiac compression or inflammation. During the procedure, the physician makes a small incision between the ribs, typically at the sixth or seventh intercostal space along the anterior axillary line, to introduce a videothoracoscope. This instrument allows for visualization of the thoracic cavity, enabling the physician to locate the cyst, tumor, or mass. Additional incisions are made to facilitate the introduction of surgical instruments necessary for the excision. The procedure requires careful dissection to remove the lesion while preserving surrounding structures, and it may involve the use of synthetic materials to repair any defects in the pericardium post-excision. Overall, this procedure is crucial for addressing pericardial lesions that may pose risks to cardiac function and overall health.

1. Indications

The procedure described by CPT® Code 32661 is indicated for the excision of pericardial cysts, tumors, or masses that may be causing symptoms or complications. The following conditions may warrant this surgical intervention:

  • Pericardial Cyst A fluid-filled sac that forms in the pericardium, which may lead to discomfort or pressure on the heart.
  • Pericardial Tumor Abnormal growths within the pericardial space that can be benign or malignant, potentially affecting heart function.
  • Pericardial Mass Any abnormal tissue growth in the pericardial area that may require removal to alleviate symptoms or prevent complications.

2. Procedure

The surgical procedure for CPT® Code 32661 involves several key steps to ensure the safe and effective excision of the pericardial cyst, tumor, or mass. The following procedural steps are performed:

  • Step 1: Incision and Access A small incision is made between the ribs, typically at the sixth or seventh intercostal space along the anterior axillary line. This incision allows for the introduction of a videothoracoscope, which provides visualization of the thoracic cavity.
  • Step 2: Inspection of the Thoracic Cavity The thoracic cavity is carefully inspected using the videothoracoscope to locate the pericardial cyst, tumor, or mass. This step is crucial for determining the extent of the lesion and planning the excision.
  • Step 3: Additional Incisions Two additional portal incisions are made at the posterior axillary line, usually at the fifth and eighth intercostal spaces. These incisions facilitate the introduction of surgical instruments necessary for the excision.
  • Step 4: Division of the Inferior Pulmonary Ligament The inferior pulmonary ligament is divided to provide better access to the pericardial area and to facilitate the removal of the lesion.
  • Step 5: Identification and Protection of the Phrenic Nerve The phrenic nerve, which is critical for diaphragm function, is identified and protected throughout the procedure to prevent any postoperative complications.
  • Step 6: Excision of the Lesion If the lesion is a cyst, it may be opened to evacuate fluid and debris. The cyst, tumor, or mass is then carefully dissected free from surrounding tissue and removed along with a margin of healthy pericardium to ensure complete excision.
  • Step 7: Closure of the Pericardium The defect in the pericardium may be covered with a synthetic patch to promote healing, or it may be left open to drain. If left open, a chest tube is placed into the defect to facilitate drainage. Additionally, a second chest tube is placed in the pleural space to manage any fluid accumulation.

3. Post-Procedure

After the completion of the thoracoscopic excision, post-procedure care is essential for recovery. Patients are typically monitored for any signs of complications, such as bleeding or infection. The placement of chest tubes allows for the drainage of any residual fluid and helps prevent the accumulation of air or fluid in the pleural space. Patients may experience some discomfort or pain at the incision sites, which can be managed with appropriate analgesics. The recovery period may vary depending on the individual patient's health status and the extent of the procedure, but close follow-up is necessary to ensure proper healing and to monitor for any recurrence of the cyst, tumor, or mass.

32674 Add-on Code MPFS Status: Active Code APC C Thoracoscopy, surgical; with mediastinal and regional lymphadenectomy (List separately in addition to code for primary procedure)
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
