CPT 31643 Bronchoscopy Reimbursement & Policy | OpenPayer

Summary & Overview

CPT 31643: Bronchoscopy with Catheter Placement for Intrapulmonary Radiotherapy

CPT code 31643 denotes a rigid or flexible bronchoscopy performed to visualize the airways and to place one or more catheters into the lung for later insertion of radioactive elements used in intrapulmonary radiotherapy. This procedure combines diagnostic airway inspection with therapeutic catheter placement and may include fluoroscopic guidance. Nationally, the code is relevant for facilities that deliver interventional pulmonology and thoracic oncology services, particularly those coordinating bronchoscopic access for brachytherapy or other localized lung radiotherapy techniques.

Key payers covered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and service settings, plus coverage and billing considerations commonly encountered with this type of bronchoscopic catheter placement. The publication summarizes typical sites of service, workflow implications for oncology and pulmonary teams, and the billing landscape for hospitals and ambulatory surgical centers. Data not available in the input for associated taxonomies, specific ICD-10 diagnoses, related codes, and payer-specific reimbursement rates.

Billing Code Overview

CPT code 31643 describes a bronchoscopy procedure performed with a rigid or flexible bronchoscope to visualize the airways. The provider may use fluoroscopic guidance. During the procedure, one or more catheters are introduced into the lung to allow subsequent placement of radioactive elements in the lung cavity for radiotherapy.

Service type: Diagnostic and therapeutic airway intervention with catheter placement for intrapulmonary radiotherapy
Typical site of service: Hospital operating room, ambulatory surgery center, or specialized interventional pulmonology suite

Clinical & Coding Specifications

Clinical Context

A 64-year-old patient with a centrally-located non-small cell lung carcinoma is scheduled for catheter placement to deliver high-dose-rate brachytherapy to a pulmonary tumor. The patient arrives to an outpatient procedural suite or hospital operating room after pre-procedure evaluation, informed consent, and imaging review. Under moderate sedation or general anesthesia, a thoracic surgeon or interventional pulmonologist performs rigid or flexible bronchoscopy to visualize the airway, identify the tumor site, and introduce one or more catheters through the bronchoscope into the bronchial lumen or tumor cavity. Fluoroscopic guidance may be used to confirm catheter position. Catheters are secured for later connection to a remote afterloading radioactive source for intracavitary radiotherapy. Typical workflow includes pre-procedure imaging review (CT/chest radiograph), airway management and monitoring, bronchoscopy with catheter placement, intra-procedural fluoroscopy as needed, documentation of catheter number and position, and post-procedure recovery with instructions for radiation oncology follow-up for source loading.
