In simple words: The doctor examines your esophagus (the tube connecting your throat to your stomach) by inserting a thin, flexible tube with a camera through your nose. During the examination, they might collect small tissue samples for analysis.This is a separate procedure and isn't billed alongside other procedures done at the same time.

This code describes a procedure where a flexible esophagoscope is inserted through the nose to examine the esophagus. It includes collecting tissue samples using brushing or washing techniques for diagnostic analysis. This is considered a separate procedure and should not be reported when performed as part of a more extensive procedure during the same session.

Example 1: A patient presents with difficulty swallowing. A flexible esophagoscopy is performed transnasally to evaluate the esophagus and collect tissue samples for biopsy to rule out eosinophilic esophagitis., A patient with chronic cough undergoes transnasal esophagoscopy to assess for laryngopharyngeal reflux. During the procedure, specimens are collected by brushing and washing for further evaluation., A patient experiences food impaction and a flexible esophagoscopy is performed transnasally. The procedure includes taking brushings of a suspicious area for cytology.

The medical record should document the indication for the esophagoscopy, the approach (transnasal), the use of a flexible endoscope, the areas examined, the methods used for specimen collection (brushing or washing), and any findings.
