About B43GYZZ

B43GYZZ is the ICD-10-PCS code for a magnetic resonance imaging (MRI) procedure on the left lower extremity 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 other and unspecified sites, the ICD-9-CM procedure title it maps to (88.97).

For a different body part, codes include B430YZZ (abdominal aorta), B431YZZ (celiac artery), B434YZZ (superior mesenteric artery), B438YZZ (bilateral renal arteries), B43CYZZ (pelvic arteries), B43FYZZ (right lower extremity arteries) and 1 more.

The same procedure with a different approach is coded B43GZZZ (none).

With a different device, use B43GY0Z (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.
