ICD-10-PCS BY3 Imaging: Fetus and Obstetrical Magnetic Resonance Imaging (MRI)

The ICD-10-PCS root operation Magnetic Resonance Imaging (MRI) (BY3) refers to capturing detailed images of the fetus or obstetrical structures using magnetic resonance technology. This imaging technique provides high-resolution, non-invasive visualization without ionizing radiation.

Within the Imaging section, these codes specify MRI procedures targeting various fetal body parts and the whole fetus. Examples include MRI of the Fetal Head (codes BY30ZZZ, BY30YZZ, BY30Y0Z), Fetal Heart (codes BY31ZZZ, BY31YZZ, BY31Y0Z), Fetal Thorax (codes BY32ZZZ, BY32YZZ, BY32Y0Z), and other regions such as the Fetal Abdomen, Spine, Extremities, and the Whole Fetus. Contrast use is differentiated by codes indicating unenhanced, enhanced, or other contrast types, allowing precise documentation of imaging technique variations. Proper coding of these fetal MRI procedures supports accurate obstetrical diagnostic records and facilitates optimized patient care.

List of ICD-10-PCS codes used to specify 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). There are a total of 22 procedure codes in this section.
