CPT 32609: Video-Assisted Endoscopic Pleural Biopsy

CPT code 32609 represents a video-assisted endoscopic pleural biopsy, a thoracic surgical procedure to obtain tissue from the pleura for diagnostic evaluation. This code matters nationally because pleural biopsy plays a central role in diagnosing malignant pleural disease, infectious pleuritis, and other causes of unexplained pleural effusion, impacting subsequent oncology, infectious disease, and pulmonary care pathways. Payment, coverage, and site-of-service considerations influence access to timely diagnosis and downstream treatment.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, common billing considerations, and expected sites of service. The publication summarizes typical use cases for the code, service line placement, and payer coverage landscape where available. It also highlights common modifiers and related billing factors for coding teams.

This resource is intended for billing professionals, practice managers, and clinicians who require a clear, national-level reference for coding and workflow alignment when documenting and submitting claims for thoracoscopic pleural biopsy procedures. Data not available in the input is noted where applicable.

Billing Code Overview

CPT code 32609 describes a video-assisted endoscopic pleural biopsy in which the provider obtains one or more tissue samples from the pleura, the membrane lining the chest cavity and enveloping the lungs. The procedure is performed using a video-assisted thoracoscopic approach that allows visualization of the pleural surfaces while sampling suspicious areas.

Service type: Surgical — thoracic endoscopic biopsy

Typical site of service: Hospital operating room or ambulatory surgery center (thoracic procedure suite)

Clinical & Coding Specifications

Clinical Context

A typical patient is a 64-year-old smoker with progressive dyspnea, pleuritic chest pain, and an unexplained unilateral pleural effusion identified on chest radiograph and confirmed by chest CT. Pulmonary medicine and thoracic surgery evaluate the patient. After initial diagnostic thoracentesis is nondiagnostic, the team recommends a video-assisted thoracoscopic pleural biopsy to obtain tissue for histology, microbiology, and cytology to evaluate for malignant mesothelioma, metastatic carcinoma, or infectious pleuritis. The procedure is performed in an operating room or ambulatory surgery center under general anesthesia with single-lung ventilation. The surgeon uses video-assisted endoscopic instruments to visualize the pleural space, inspects pleural surfaces, and obtains one or more tissue samples from abnormal pleural areas. Specimens are sent for pathology and cultures. Typical workflow includes preoperative consent and imaging review, anesthesia induction, placement of endoscopic ports, targeted pleural biopsies, possible pleurodesis if indicated, chest tube placement, post-anesthesia recovery, and discharge or inpatient admission based on clinical status.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when billing only the surgeon/physician interpretation or intraoperative professional service separate from technical facility costs.
`50`	Bilateral procedure	Use when bilateral pleural biopsies are performed during the same operative session.
`51`	Multiple procedures	Use when additional distinct procedures are performed during the same operative episode and payer requires modifier for multiple procedures.
`52`	Reduced services	Use when the biopsy procedure is started but substantially reduced or incomplete.
`53`	Discontinued procedure	Use when the procedure is terminated due to extenuating circumstances prior to completion.
`59`	Distinct procedural service	Use to indicate a distinct procedure not normally billed together, e.g., separate pleural biopsy distinct from a concurrent thoracotomy procedure.
`62`	Two surgeons	Use when two surgeons work together as primary surgeons performing distinct portions of the procedure.
`63`	Procedure performed on infants less than 4 kg	Use when patient meets weight criteria and procedure is on a neonate/infant as defined by payer guidance.
`66`	Surgical team	Use when a team approach is reported per payer rules for complex thoracic procedures.
`78`	Unplanned return to OR following initial procedure	Use when a patient returns to the operating room for a related procedure during the postoperative period.

`81`	Minimum assistant surgeon	Use when a minimal assistant surgeon service is provided and permitted by payer rules.
`82`	Assistant surgeon (when qualified resident not available)	Use when a qualified resident is not available and an assistant is necessary.
`59`	Distinct procedural service	Use when services are separate and unrelated on the same day; avoid unbundling; use only when clinical circumstances justify.
