About 0U9L0ZZ

0U9L0ZZ is the ICD-10-PCS code for a drainage procedure on the vestibular gland using an open approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to percutaneous aspiration of Bartholin's gland (cyst), the ICD-9-CM procedure title it maps to (71.21).

For a different body part, codes include 0U900ZZ (right ovary), 0U910ZZ (left ovary), 0U920ZZ (bilateral ovaries), 0U940ZZ (uterine supporting structure), 0U950ZZ (right fallopian tube), 0U960ZZ (left fallopian tube) and 8 more.

The same procedure with a different approach is coded 0U9LXZZ (external).

With a different device, use 0U9L00Z (drainage device).

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.
