Summary & Overview
CPT 43197: Transnasal Flexible Esophagoscopy with Brushing/Washings
CPT code 43197 represents a diagnostic transnasal flexible esophagoscopy with collection of cells by brushing or washing. This procedure is used to evaluate esophageal symptoms such as dysphagia and to obtain cytologic specimens for laboratory analysis. Nationally, the code matters for accurate classification of endoscopic diagnostic services and appropriate tracking of minimally invasive esophageal sampling techniques.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Billing Code Overview
CPT code 43197 describes a diagnostic transnasal flexible esophagoscopy with collection of cellular samples by brushing or washing. The procedure involves inserting a flexible esophagoscope through the nose to visualize the esophagus using a light source and camera to identify causes of symptoms such as difficulty swallowing. Suspicious areas are sampled by brushing or washing to obtain cells for laboratory analysis.
-
Service type: Diagnostic endoscopic procedure of the esophagus with cytologic sampling (brushing/washings)
-
Typical site of service: Ambulatory surgical center or hospital outpatient department; may also be performed in an endoscopy suite or specialized outpatient clinic
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient presents to an outpatient endoscopy suite with progressive dysphagia to solids and episodic regurgitation. The otolaryngologist or gastroenterologist performs a flexible transnasal esophagoscopy using a slim, flexible esophagoscope inserted through the nasal cavity to visualize the esophageal mucosa. During the procedure, the provider inspects for strictures, rings, webs, mucosal lesions, and signs of reflux injury. If an area appears suspicious for inflammation, dysplasia, or neoplasia, the provider obtains cytologic sampling by brushings or performs esophageal washings to collect cells for laboratory cytology. The typical workflow includes pre-procedure assessment, topical nasal anesthesia and decongestant, monitored sedation as indicated, the transnasal esophagoscopy with targeted brushing/washings, specimen labeling and submission to the pathology/cytology laboratory, post-procedure recovery, and documentation of findings and follow-up recommendations. Typical site of service is an outpatient endoscopy suite, ambulatory surgery center, or hospital outpatient department.
