ICD-10-PCS Body System: ICD-10-PCS Body System BW - Anatomical Regions

The ICD-10-PCS root operation BW - Anatomical Regions refers to a group of imaging techniques used to visualize specific parts of the body for diagnostic purposes. This operation encompasses multiple modalities that capture and display images of anatomical regions without direct physical intervention.

Within the Imaging classification, these codes describe various imaging methods. For example, Plain Radiography (BW0) produces planar images from external ionizing radiation on photographic plates. Fluoroscopy (BW1) provides real-time image display on a fluorescent screen and may involve single or biplane techniques. Advanced imaging like Computerized Tomography (CT scan) (BW2) and Magnetic Resonance Imaging (MRI) (BW3) offer digitally reformatted multiplanar views using ionizing radiation and radio frequency signals respectively. Additionally, Ultrasonography (BW4) captures images through high-frequency sound waves, while Other Imaging (BW5) covers alternative imaging modalities. These codes help medical coders accurately document different imaging procedures performed to assess anatomical regions.

List of ICD-10-PCS procedures under ICD-10-PCS Body System BW - Anatomical Regions

  • BW0 - Plain Radiography - Planar display of an image developed from the capture of external ionizing radiation on photographic or photoconductive plate

  • BW1 - 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

  • BW2 - Computerized Tomography (CT Scan) - Computer-reformatted digital display of multiplanar images developed from the capture of multiple exposures of external ionizing radiation

  • BW3 - 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

  • BW4 - Ultrasonography - Real time display of images of anatomy or flow information developed from the capture of reflected and attenuated high frequency sound waves

  • BW5 - Other Imaging - Other specified modality for visualizing a body part
