About 0U9G4ZX

0U9G4ZX is the ICD-10-PCS code for a drainage procedure on the vagina using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to vaginal biopsy, the ICD-9-CM procedure title it maps to (70.24).

For a different body part, codes include 0U904ZX (right ovary), 0U914ZX (left ovary), 0U924ZX (bilateral ovaries), 0U944ZX (uterine supporting structure), 0U954ZX (right fallopian tube), 0U964ZX (left fallopian tube) and 5 more.

The same procedure with a different approach is coded 0U9G0ZX (open), 0U9G3ZX (percutaneous), 0U9G7ZX (via natural or artificial opening), 0U9G8ZX (via natural or artificial opening endoscopic) and 0U9GXZX (external).

It is an operating-room procedure in the MS-DRG logic for DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC), DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), DRG 746 (Vagina, Cervix and Vulva Procedures with CC/MCC) and DRG 747 (Vagina, Cervix and Vulva Procedures without CC/MCC), under the surgical categories “Other Skin, Subcutaneous Tissue and Breast Procedures” and “Vagina, Cervix and Vulva Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
