About B335ZZZ
B335ZZZ is the ICD-10-PCS code for a magnetic resonance imaging (MRI) procedure on the bilateral common carotid arteries using a none 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 other and unspecified sites, the ICD-9-CM procedure title it maps to (88.97).
For a different body part, codes include B330ZZZ (thoracic aorta), B338ZZZ (bilateral internal carotid arteries), B33GZZZ (bilateral vertebral arteries), B33HZZZ (right upper extremity arteries), B33JZZZ (left upper extremity arteries), B33KZZZ (bilateral upper extremity arteries) and 3 more.
The same procedure with a different approach is coded B335YZZ (other contrast).
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.
