Summary & Overview

CPT 43510: Esophageal Stent Placement for Stricture Palliation

CPT code 43510 represents the placement of a permanent intraluminal esophageal stent to relieve symptomatic esophageal stricture, most often used for palliation of obstruction from malignancy or radiation-induced scarring. Nationally, this procedure is an important component of palliative care pathways for advanced esophageal disease, reducing dysphagia and improving quality of life for patients with unresectable tumors or severe benign strictures.

Key national payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, and an explanation of how CPT code 43510 is used in billing. The report summarizes common billing modifiers associated with the service and highlights areas where policy updates, medical necessity criteria, and documentation requirements commonly influence coverage and reimbursement.

This publication also provides benchmarks and practical guidance on coding accuracy and claim documentation to support appropriate use of CPT code 43510 in hospital outpatient and ambulatory surgery settings. The content is presented to inform billing staff, clinicians, and policy analysts involved in esophageal stent placement services.

Billing Code Overview

CPT code 43510 describes the placement of an indwelling (permanent) intraluminal tube or stent through an area of esophageal stricture. The procedure is typically performed to relieve obstruction caused by tumor overgrowth or fibrotic narrowing following radiation therapy and is performed for palliative treatment of esophageal stricture.

Service type: Endoscopic or fluoroscopically guided esophageal stent placement for palliation of obstructive esophageal stricture
Typical site of service: Hospital outpatient department or ambulatory surgery center; may also be performed in interventional radiology suites or endoscopy units within a hospital setting.

Clinical & Coding Specifications

Clinical Context

A 68-year-old male with a history of esophageal squamous cell carcinoma treated with chemoradiation presents with progressive dysphagia to solids and impaired oral intake. Endoscopic evaluation demonstrates a malignant mid‑esophageal stricture causing near‑obstruction with inability to maintain adequate nutrition and risk for aspiration. The care team elects palliative endoscopic placement of a permanent self‑expanding intraluminal esophageal stent to restore luminal patency and allow oral intake.

The clinical workflow includes pre‑procedure evaluation (history, medication review, consent, coagulation assessment), sedation or monitored anesthesia care, endoscopic localization and dilation as needed, deployment of the stent across the stricture under endoscopic and fluoroscopic guidance, confirmation of stent position and patency, recovery monitoring, and discharge planning with dietary and follow‑up instructions. Typical site of service is an endoscopy suite, ambulatory surgery center, or hospital operating room depending on patient condition and anesthesia needs. Service type is palliative therapeutic endoscopic stent placement for esophageal obstruction.
