About BP231ZZ
BP231ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the bilateral acromioclavicular joints using a low osmolar 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 computerized axial tomography, the ICD-9-CM procedure title it maps to (88.38).
For a different body part, codes include BP201ZZ (right sternoclavicular joint), BP211ZZ (left sternoclavicular joint), BP221ZZ (bilateral sternoclavicular joints), BP241ZZ (right clavicle), BP251ZZ (left clavicle), BP261ZZ (right scapula) and 24 more.
The same procedure with a different approach is coded BP230ZZ (high osmolar), BP23YZZ (other contrast) and BP23ZZZ (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.
