About B43GY0Z

B43GY0Z 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 unenhanced and enhanced (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 B430Y0Z (abdominal aorta), B431Y0Z (celiac artery), B434Y0Z (superior mesenteric artery), B438Y0Z (bilateral renal arteries), B43CY0Z (pelvic arteries), B43FY0Z (right lower extremity arteries) and 1 more.

With a different device, use B43GYZZ (none).

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.
