About B42FZ2Z
B42FZ2Z is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the right lower extremity arteries 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 B420Z2Z (abdominal aorta), B421Z2Z (celiac artery), B424Z2Z (superior mesenteric artery), B428Z2Z (bilateral renal arteries), B42CZ2Z (pelvic arteries), B42GZ2Z (left lower extremity arteries) and 2 more.
With a different device, use B42FZZZ (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.
