About 0U9K0ZZ

0U9K0ZZ is the ICD-10-PCS code for a drainage procedure on the hymen 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 Hymenotomy, the ICD-9-CM procedure title it maps to (70.11).

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 0U9K3ZZ (percutaneous), 0U9K4ZZ (percutaneous endoscopic), 0U9K7ZZ (via natural or artificial opening), 0U9K8ZZ (via natural or artificial opening endoscopic) and 0U9KXZZ (external).

With a different device, use 0U9K00Z (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.
