About the B53 Code Range

The ICD-10-PCS root operation Magnetic Resonance Imaging (MRI) (Code B53) involves creating detailed images of veins using magnetic resonance technology. This falls under the Imaging section and specifically targets veins in various regions of the body.

The ICD-10-PCS MRI operation includes procedures such as imaging the cerebral and cerebellar veins (e.g., B531ZZZ), intracranial sinuses (B532ZZZ), and major vessels like the superior (B538ZZZ) and inferior vena cava (B539ZZZ). MRI can also evaluate veins in the upper and lower extremities bilaterally or individually (e.g., B53DYZZ for bilateral lower extremity veins), as well as the renal, pulmonary, portal, and pelvic veins. These codes distinguish between unenhanced, enhanced, and other contrast usage to provide precise procedural documentation. Leveraging these specialized MRI codes ensures accurate record-keeping of diagnostic imaging focused on venous structures throughout the body.

Questions About This Page

How many billable codes are in the B53 range?

Of the 49 codes in this range, 48 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 B53 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 veins. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
