About BW29ZZZ
BW29ZZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the head and neck using a none approach with none (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 BW20ZZZ (abdomen), BW21ZZZ (abdomen and pelvis), BW24ZZZ (chest and abdomen), BW25ZZZ (chest, abdomen and pelvis), BW28ZZZ (head), BW2FZZZ (neck) and 1 more.
The same procedure with a different approach is coded BW290ZZ (high osmolar), BW291ZZ (low osmolar) and BW29YZZ (other contrast).
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.
