ICD-10-PCS Body System: ICD-10-PCS Body System B9 - Ear, Nose, Mouth and Throat

The ICD-10-PCS root operation B9 refers to Imaging within the Ear, Nose, Mouth and Throat body system. This operation involves capturing visual representations of these anatomical regions for diagnostic purposes without any direct physical intervention.

This imaging operation includes several distinct modalities. Plain Radiography (B90) produces planar images using external ionizing radiation captured on a photographic or photoconductive plate. Fluoroscopy (B91) provides real-time, single or bi-plane imaging with ionizing radiation displayed on a fluorescent screen, which may be stored digitally or analogically. More advanced techniques include Computerized Tomography (CT Scan) (B92), which generates computer-reformatted multiplanar images from multiple radiation exposures, and Magnetic Resonance Imaging (MRI) (B93), which creates digital images from radiofrequency signals emitted by nuclei excited within a magnetic field. These ear, nose, mouth and throat imaging codes enable precise documentation of diagnostic imaging procedures essential for clinical evaluation and treatment planning.

List of ICD-10-PCS procedures under ICD-10-PCS Body System B9 - Ear, Nose, Mouth and Throat

  • B90 - Plain Radiography - Planar display of an image developed from the capture of external ionizing radiation on photographic or photoconductive plate

  • B91 - Fluoroscopy - Single plane or bi-plane real time display of an image developed from the capture of external ionizing radiation on fluorescent screen. The image may also be stored by either digital or analog means

  • B92 - Computerized Tomography (CT Scan) - Computer-reformatted digital display of multiplanar images developed from the capture of multiple exposures of external ionizing radiation

  • B93 - Magnetic Resonance Imaging (MRI) - Computer reformatted digital display of multiplanar images developed from the capture of radio frequency signals emitted by nuclei in a body site excited within a magnetic field
