About BU121ZZ
BU121ZZ is the ICD-10-PCS code for a fluoroscopy procedure on the bilateral fallopian tubes 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 x-ray of fallopian tubes and uterus, the ICD-9-CM procedure title it maps to (87.85).
For a different body part, codes include BU101ZZ (right fallopian tube), BU111ZZ (left fallopian tube), BU161ZZ (uterus), BU181ZZ (uterus and fallopian tubes) and BU191ZZ (vagina).
The same procedure with a different approach is coded BU120ZZ (high osmolar), BU12YZZ (other contrast) and BU12ZZZ (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.
