About BF121ZZ
BF121ZZ is the ICD-10-PCS code for a fluoroscopy procedure on the gallbladder 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 other biliary tract x-ray, the ICD-9-CM procedure title it maps to (87.59).
For a different body part, codes include BF101ZZ (bile ducts), BF111ZZ (biliary and pancreatic ducts), BF131ZZ (gallbladder and bile ducts), BF141ZZ (gallbladder, bile ducts and pancreatic ducts), BF151ZZ (liver) and BF181ZZ (pancreatic ducts).
The same procedure with a different approach is coded BF120ZZ (high osmolar) and BF12YZZ (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.
