ICD-10-PCS Body System: ICD-10-PCS Body System BY - Fetus and Obstetrical

The ICD-10-PCS root operation BY refers to Fetus and Obstetrical Imaging, which involves producing diagnostic images of the fetus or obstetrical structures. This operation is essential for monitoring fetal development and evaluating pregnancy status without invasive procedures.

Within the Imaging classification, key methods include Magnetic Resonance Imaging (MRI) and Ultrasonography. MRI (code BY3) generates detailed multiplanar images by capturing radio frequency signals from nuclei excited within a magnetic field. Ultrasonography (code BY4) uses high-frequency sound waves to create real-time images of fetal anatomy or blood flow. Both techniques provide critical, non-invasive visualization tools fundamental to obstetrical care. Accurate coding with these fetus and obstetrical imaging options ensures clear communication regarding the specific imaging technology and approach used during pregnancy management.

List of ICD-10-PCS procedures under ICD-10-PCS Body System BY - Fetus and Obstetrical

  • BY3 - 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

  • BY4 - Ultrasonography - Real time display of images of anatomy or flow information developed from the capture of reflected and attenuated high frequency sound waves
