About BW29Y0Z
BW29Y0Z is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the head and neck using an other contrast approach with unenhanced and enhanced (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 other tomography of head, the ICD-9-CM procedure title it maps to (87.04).
For a different body part, codes include BW20Y0Z (abdomen), BW21Y0Z (abdomen and pelvis), BW24Y0Z (chest and abdomen), BW25Y0Z (chest, abdomen and pelvis), BW28Y0Z (head), BW2FY0Z (neck) and 1 more.
The same procedure with a different approach is coded BW2900Z (high osmolar) and BW2910Z (low osmolar).
With a different device, use BW29YZZ (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.
