ICD-10-PCS Code For Nasopharynx Oropharynx: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group B92F includes procedures performed to capture and digitally reformat multiplanar images of the nasopharynx and oropharynx using computerized tomography. These ICD-10-PCS codes are used for inpatient documentation when multiplanar digital display images derived from multiple external ionizing radiation exposures are obtained for diagnostic or treatment planning purposes. Accurate coding within the ICD-10-PCS B92F group is essential for proper inpatient reimbursement, as it captures the imaging procedure performed and supports clinical documentation accuracy.

Nasopharynx/Oropharynx Computerized Tomography Procedure Overview

This procedure group includes computerized tomography imaging of the nasopharynx and oropharynx, using multiple external ionizing radiation exposures reformatted into multiplanar digital displays. These procedures target the ear, nose, mouth, and throat body system and provide detailed cross-sectional visualization of nasopharyngeal and oropharyngeal structures. Accurate ICD-10-PCS coding ensures the inpatient record reflects the specific imaging performed and supports appropriate reimbursement.

When to Use

Use codes from this group when multiplanar CT images of the nasopharynx or oropharynx are created from multiple external ionizing radiation exposures for diagnosis or surgical planning. Do not use this group for other imaging modalities or for procedures targeting different anatomical sites.

Typical Clinical Scenarios

A middle-aged adult is admitted through the emergency department with sudden-onset severe epistaxis and facial trauma after a motor vehicle collision. Concern for nasopharyngeal hemorrhage and suspected fractures with possible vascular injury prompts acquisition of multiplanar CT images of the nasopharynx and oropharynx to identify the bleeding source and plan endoscopic or interventional management. Contrast administration is performed to evaluate vascular structures and active extravasation. Typical codes: B92FY0Z
A patient with progressive unilateral nasal obstruction and suspected nasopharyngeal tumor is admitted for workup and staging prior to planned surgical resection. Multiplanar CT imaging of the nasopharynx and oropharynx is obtained using contrast to delineate tumor extent, involvement of adjacent structures, and assist operative planning. Low osmolar contrast is selected to optimize vessel and soft-tissue enhancement while minimizing contrast-related risk. Typical codes: B92F10Z
A postoperative inpatient who underwent endoscopic nasopharyngeal surgery develops increasing oropharyngeal swelling and concern for postoperative hematoma compromising the airway. Repeat multiplanar CT of the nasopharynx and oropharynx is performed without additional contrast to evaluate the extent of hematoma and airway compression and to guide urgent return to the operating room if needed. Typical codes: B92FZZZ
