B33GYZZMagnetic Resonance Imaging (MRI) of Bilateral Vertebral Arteries using Other Contrast
- Billable / Specific Code
B33GYZZ is a billable ICD-10-PCS procedure code for Magnetic Resonance Imaging (MRI) of Bilateral Vertebral Arteries using Other Contrast. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027). The root operation Magnetic Resonance Imaging (MRI) involves computer reformatted digital display of multiplanar images developed from the capture of radiofrequency signals emitted by nuclei in a body site excited within a magnetic field. In AHRQ's Clinical Classifications Software (CCSR), this procedure falls under Magnetic resonance imaging (MRI).
