Nasal Bones ICD-10-PCS Coding & Reimbursement

ICD-10-PCS Code For Nasal Bones: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BN04 includes procedures performed to image bony structures in the nasal bones using plain radiography. These ICD-10-PCS codes are used for inpatient documentation when plain radiographic imaging of the nasal bones is performed to evaluate fractures, deformity, or other bony pathology as part of the inpatient encounter. Accurate coding within the ICD-10-PCS BN04 group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Nasal Bones Plain Radiography Procedure Overview

This procedure group includes plain radiography imaging performed on the nasal bones, part of the skull and facial bones body system. These procedures capture planar images using external ionizing radiation on photographic or photoconductive plate to evaluate fractures, deformities, or other bony pathology. Accurate ICD-10-PCS coding of these imaging procedures supports proper inpatient documentation and reimbursement by reflecting the specific body part and imaging operation performed.

When to Use

Use a code from this group when an inpatient receives plain radiographic imaging specifically of the nasal bones to evaluate trauma, suspected fracture, or other bony abnormality. Select the code when the imaging modality is plain radiography captured by external ionizing radiation on photographic or photoconductive plate.

ICD-10-PCS Code

Description

BN04ZZZ

Plain Radiography of Nasal Bones

Typical Clinical Scenarios

A young adult presents to the emergency department after a midface blunt trauma from an assault with nasal deformity, epistaxis, and localized bony tenderness; the patient is admitted for observation and facial trauma workup to assess for nasal bone fracture and surgical planning. Plain radiography of the nasal bones is performed to quickly evaluate bony alignment and identify obvious fractures as part of the inpatient imaging evaluation. Typical codes: BN04ZZZ
An elderly inpatient on a medical ward reports new onset nasal pain and swelling after a low‑impact fall at the nursing facility; the team admits the patient for fall evaluation and concerns for occult nasal bone injury given anticoagulation use increasing bleeding risk. A targeted plain radiograph of the nasal bones is obtained to detect fractures or displacement that could alter management while the patient remains hospitalized. Typical codes: BN04ZZZ
A postoperative patient who underwent closed reduction of a nasal fracture earlier in the admission develops increasing deformity and persistent instability of the nasal bridge; the surgical and inpatient teams order follow‑up plain radiography to assess recurrent displacement or fixation failure before deciding on revision intervention. Typical codes: BN04ZZZ
