CPT 43196: Rigid Esophagoscopy with Guidewire and Dilators
CPT code 43196 denotes a rigid esophagoscopy performed through the mouth with placement of a guidewire and one or more dilators to treat esophageal strictures. Nationally, this code represents a focused therapeutic endoscopic procedure used to restore esophageal patency, improve swallowing, and address obstructive symptoms from benign or malignant disease. The procedure is typically delivered in ambulatory surgical centers or hospital operating rooms and is performed by otolaryngology, thoracic surgery, or gastroenterology specialists who use rigid endoscopic techniques.
Key payers considered in the overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Clinical & Coding Specifications
Clinical Context
A 62-year-old male with a history of progressive solid-food dysphagia and unintentional weight loss is referred to an otolaryngologist for evaluation. Office-based flexible endoscopy suggests a proximal esophageal stricture. The patient is scheduled for a diagnostic and therapeutic rigid esophagoscopy with guidewire-assisted dilation under general anesthesia in an ambulatory surgery center. Pre-procedure workflow includes history and physical, informed consent, anesthesia assessment, NPO verification, and review of anticoagulation. In the operating room, a rigid endoscope is introduced through the mouth, the stricture is traversed with a flexible guidewire, and serial dilators are passed over the wire to restore luminal diameter. Post-procedure workflow includes recovery monitoring for airway compromise, observation for perforation or bleeding, discharge instructions, and scheduling follow-up for symptom reassessment and pathology results if biopsies were taken.
