ICD-10-PCS Body System: ICD-10-PCS Body System B4 - Lower Arteries

The ICD-10-PCS root operation Lower Arteries (B4) within the Imaging section refers to diagnostic procedures that visualize the arteries in the lower body using various imaging technologies.

This operation captures detailed images of the lower arteries to assess blood flow, detect blockages, or guide treatment planning. Different imaging modalities are represented by specific codes: Plain Radiography (B40) uses external ionizing radiation on photographic plates to create planar images, while Fluoroscopy (B41) provides real-time visualization using a fluorescent screen. Computerized Tomography (CT Scan) (B42) produces multiplanar digital images from multiple exposures, and Magnetic Resonance Imaging (MRI) (B43) utilizes radio frequency signals within a magnetic field for detailed soft tissue contrast. Additionally, Ultrasonography (B44) offers real-time images based on high-frequency sound waves to visualize anatomy and blood flow. These lower artery imaging methods are crucial for accurate diagnosis and guiding interventions in vascular conditions.

List of ICD-10-PCS procedures under ICD-10-PCS Body System B4 - Lower Arteries

  • B40 - Plain Radiography - Planar display of an image developed from the capture of external ionizing radiation on photographic or photoconductive plate

  • B41 - 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

  • B42 - Computerized Tomography (CT Scan) - Computer-reformatted digital display of multiplanar images developed from the capture of multiple exposures of external ionizing radiation

  • B43 - 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

  • B44 - Ultrasonography - Real time display of images of anatomy or flow information developed from the capture of reflected and attenuated high frequency sound waves
