About B221Z2Z
B221Z2Z is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the coronary arteries, multiple 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 coronary vessel(s) by optical coherence tomography [OCT], the ICD-9-CM procedure title it maps to (38.24).
For a different body part, codes include B223Z2Z (coronary artery bypass grafts, multiple) and B226Z2Z (heart, right and left).
With a different device, use B221ZZZ (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.
