ICD-10-PCS Code For Pharynx And Epiglottis: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group B91G includes procedures performed to image structures in the pharynx and epiglottis in the ear, nose, mouth and throat body system. These ICD-10-PCS codes are used for inpatient documentation when real time fluoroscopic imaging is performed using external ionizing radiation to evaluate or document pharyngeal and epiglottic anatomy or function. Accurate coding within the ICD-10-PCS B91G group is essential for proper inpatient reimbursement, as it captures the imaging operation performed and the specific body part imaged which determines appropriate case mix and payment.

Pharynx And Epiglottis Fluoroscopy Procedure Overview

This procedure group includes fluoroscopic imaging of the pharynx and epiglottis within the ear, nose, mouth and throat body system. Procedures involve single plane or bi-plane real time display of images developed from external ionizing radiation to evaluate structure and function. Accurate ICD-10-PCS coding is important for inpatient reimbursement because it captures the specific imaging operation and body part, supporting proper case mix classification and payment.

When to Use

Use a code from this group when inpatient fluoroscopic imaging is performed to evaluate or document the pharynx or epiglottis. This includes studies done for assessment of anatomy, swallowing function, or guidance during related diagnostic procedures.

Typical Clinical Scenarios

An elderly patient is admitted from the emergency department with acute dysphagia and suspected aspiration after a witnessed choking episode; bedside evaluation is inconclusive and concern for pharyngeal structural abnormality or epiglottic dysfunction prompts real‑time radiographic assessment of swallowing and airway protection. A fluoroscopic swallow study of the pharynx and epiglottis is performed to visualize bolus transit and identify aspiration risk while images are captured digitally. Typical codes: B91GZZZ, B91GYZZ
A middle‑aged patient with progressive odynophagia and a known pharyngeal mass is scheduled for inpatient imaging prior to operative planning; dynamic fluoroscopic imaging is used to assess tumor effect on pharyngeal contour and epiglottic mobility under contrast for surgical mapping. Single‑plane fluoroscopy documents anatomy and function to guide the surgical team’s approach. Typical codes: B91GYZZ, B91GZZZ
A postoperative inpatient who underwent transoral surgery develops persistent throat discomfort and suspected postoperative pharyngeal narrowing affecting swallowing; fluoroscopic evaluation is ordered to assess postoperative pharyngeal and epiglottic anatomy and to determine need for further intervention or modified diet. Real‑time fluoroscopic imaging with possible contrast delineates structural complication and swallowing mechanics. Typical codes: B91GZZZ, B91GYZZ
