About 0U9F4ZX

0U9F4ZX is the ICD-10-PCS code for a drainage procedure on the cul-de-sac 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 biopsy of cul-de-sac, the ICD-9-CM procedure title it maps to (70.23).

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 0U9F0ZX (open), 0U9F3ZX (percutaneous), 0U9F7ZX (via natural or artificial opening) and 0U9F8ZX (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 746 (Vagina, Cervix and Vulva Procedures with CC/MCC) and DRG 747 (Vagina, Cervix and Vulva Procedures without CC/MCC), under the surgical category “Vagina, Cervix and Vulva Procedures”.

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