About B33RYZZ
B33RYZZ is the ICD-10-PCS code for a magnetic resonance imaging (MRI) procedure on the intracranial arteries using an other contrast approach with none (qualifier: none). In ICD-10-PCS, magnetic resonance imaging (MRI) means 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 plain terms, this corresponds to magnetic resonance imaging of brain and brain stem, the ICD-9-CM procedure title it maps to (88.91).
For a different body part, codes include B330YZZ (thoracic aorta), B335YZZ (bilateral common carotid arteries), B338YZZ (bilateral internal carotid arteries), B33GYZZ (bilateral vertebral arteries), B33HYZZ (right upper extremity arteries), B33JYZZ (left upper extremity arteries) and 3 more.
The same procedure with a different approach is coded B33RZZZ (none).
With a different device, use B33RY0Z (unenhanced and enhanced).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
