Summary & Overview
HCPCS C9751: Bronchoscopy with Transbronchial Microwave Ablation and Image-Guided EBUS
HCPCS Level II code C9751 represents a high-complexity bronchoscopic intervention that combines transbronchial microwave ablation of pulmonary lesions with multimodal image guidance and endobronchial ultrasound (EBUS)-guided sampling. The code captures both therapeutic ablation and comprehensive diagnostic staging when CT-based 3-D rendering, computer-assisted navigation, fluoroscopy, and EBUS sampling of mediastinal/hilar nodes are performed. Nationally, this code matters because it codifies advanced, image-guided interventional pulmonology procedures that integrate therapy and staging in a single session, with implications for reimbursement, facility resource planning, and care pathways for patients with pulmonary lesions.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical scope and service settings, payer coverage context, common modifiers, and areas where policy and billing complexity are most likely to arise. The publication outlines benchmarks and coding considerations relevant to hospital outpatient departments, ambulatory surgical centers, and inpatient operative settings, and highlights the clinical integration of ablation with diagnostic sampling. Data not available in the input is indicated where applicable.
Billing Code Overview
HCPCS Level II code C9751 describes a complex bronchoscopic procedure: rigid or flexible bronchoscopy with transbronchial microwave ablation of lesion(s). The procedure includes computed tomography acquisition(s) with 3-D rendering, computer-assisted image-guided navigation, fluoroscopic guidance when performed, and endobronchial ultrasound (EBUS) guided transtracheal and/or transbronchial sampling (e.g., aspiration(s)/biopsy(ies)) with assessment of all mediastinal and/or hilar lymph node stations or structures and therapeutic interventions.
Service type: Image-guided interventional pulmonology procedure combining ablation and diagnostic sampling.
Typical site of service: Hospital outpatient department or ambulatory surgical center; may also occur in inpatient operative settings depending on clinical context and patient condition.
Clinical & Coding Specifications
Clinical Context
A 67-year-old current smoker with a 45-pack-year history presents with a 2.5 cm spiculated right upper lobe pulmonary nodule found on surveillance chest CT and progressive cough. PET-CT demonstrates hypermetabolic activity in the nodule and borderline FDG uptake in a right hilar node. The pulmonologist recommends bronchoscopic evaluation with tissue diagnosis and possible local tumor ablation. The procedure performed is a bronchoscopic transbronchial microwave ablation using a flexible bronchoscope with endobronchial ultrasound (EBUS) for sampling of mediastinal and hilar lymph nodes, computer-assisted image-guided navigation using pre-procedure CT with 3-D rendering, and fluoroscopic guidance as needed.
Pre-procedure workflow includes review of imaging and navigation plan by the bronchoscopist and procedural team, informed consent emphasizing both diagnostic sampling and therapeutic ablation, anesthesia assessment (typically monitored anesthesia care or general anesthesia), and setup of the navigation system with CT data for real-time guidance. During the procedure the team performs EBUS-guided fine-needle aspiration of mediastinal/hilar lymph nodes, transbronchial biopsies of the peripheral lesion using navigation to guide the microwave ablation catheter, and then delivers microwave energy to ablate the target lesion. Immediate post-procedure care includes airway assessment, chest radiograph if indicated, monitoring for bleeding or pneumothorax, and instruction for follow-up imaging to assess ablation efficacy and sampling results.
