About the BU3 Code Range
The ICD-10-PCS root operation Magnetic Resonance Imaging (MRI) (code prefix BU3) refers to using MRI technology to create detailed images of body parts for diagnostic purposes. This operation is classified under the Imaging section and focuses on the female reproductive system.
This root operation encompasses MRI procedures targeting specific anatomical sites such as the right ovary, left ovary, bilateral ovaries, uterus, pregnant uterus, and vagina. The codes show variations that include imaging with or without contrast agents, and contrast types like "Other Contrast," further divided into unenhanced and enhanced imaging. For example, code BU33Y0Z describes an MRI of the right ovary using other contrast with both unenhanced and enhanced phases, while BU36ZZZ refers to an MRI of the uterus without contrast. Accurate use of these codes supports detailed documentation of MRI imaging specifically related to the female reproductive system in clinical records.
Questions About This Page
How many billable codes are in the BU3 range?
Of the 22 codes in this range, 21 are billable and valid for inpatient claim submission from October 1, 2025 through September 30, 2026. Table header codes group them but cannot be reported on claims.
What does the BU3 range classify?
The range classifies Magnetic Resonance Imaging (MRI) procedures, 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, performed on the female reproductive system. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
