About BR121ZZ
BR121ZZ is the ICD-10-PCS code for a fluoroscopy procedure on the thoracic disc(s) using a low osmolar approach with none (qualifier: none). In ICD-10-PCS, fluoroscopy means single plane or bi-plane real time display of an image developed from the capture of external ionizing radiation on a fluorescent screen. The image may also be stored by either digital or analog means.
In plain terms, this corresponds to contrast myelogram, the ICD-9-CM procedure title it maps to (87.21).
For a different body part, codes include BR101ZZ (cervical spine), BR111ZZ (cervical disc(s)), BR131ZZ (lumbar disc(s)), BR141ZZ (cervical facet joint(s)), BR151ZZ (thoracic facet joint(s)), BR161ZZ (lumbar facet joint(s)) and 9 more.
The same procedure with a different approach is coded BR120ZZ (high osmolar), BR12YZZ (other contrast) and BR12ZZZ (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.
