About the B43 Code Range
The ICD-10-PCS root operation Magnetic Resonance Imaging (MRI) (code B43) involves using magnetic resonance technology to create detailed images of blood vessels. This operation focuses on capturing noninvasive imaging data for diagnostic or evaluation purposes within the Imaging section.
This ICD-10-PCS Magnetic Resonance Imaging operation applies to various arteries in the body. Examples include imaging the Abdominal Aorta with or without contrast enhancement (codes B430ZZZ, B430Y0Z), the Celiac Artery (B431ZZZ, B431Y0Z), and the Superior Mesenteric Artery (B434ZZZ, B434Y0Z). It also covers vascular imaging of the Bilaterial Renal Arteries (B438ZZZ), Pelvic Arteries (B43CZZZ), and both right and left lower extremity arteries (e.g., B43FZZZ and B43GZZZ). The specificity of these codes ensures precise documentation of the artery imaged, the use of contrast if applicable, and bilateral involvement when relevant, supporting accurate clinical and billing records.
Questions About This Page
How many billable codes are in the B43 range?
Of the 25 codes in this range, 24 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 B43 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 lower arteries. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
