B420Z2ZComputerized Tomography (CT Scan) of Abdominal Aorta using Intravascular Optical Coherence

B420Z2Z is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the abdominal aorta using a none approach with intravascular optical coherence (qualifier: none). In ICD-10-PCS, computerized tomography (CT scan) means computer reformatted digital display of multiplanar images developed from the capture of multiple exposures of external ionizing radiation.

In plain terms, this corresponds to intravascular imaging of non-coronary vessel(s) by optical coherence tomography [OCT], the ICD-9-CM procedure title it maps to (38.25).

For a different body part, codes include B421Z2Z (celiac artery), B424Z2Z (superior mesenteric artery), B428Z2Z (bilateral renal arteries), B42CZ2Z (pelvic arteries), B42FZ2Z (right lower extremity arteries), B42GZ2Z (left lower extremity arteries) and 2 more.

With a different device, use B420ZZZ (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.
