About 0U998ZX

0U998ZX is the ICD-10-PCS code for a drainage procedure on the uterus using a via natural or artificial opening 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 closed biopsy of uterus, the ICD-9-CM procedure title it maps to (68.16).

For a different body part, codes include 0U908ZX (right ovary), 0U918ZX (left ovary), 0U928ZX (bilateral ovaries), 0U948ZX (uterine supporting structure), 0U958ZX (right fallopian tube), 0U968ZX (left fallopian tube) and 5 more.

The same procedure with a different approach is coded 0U990ZX (open), 0U993ZX (percutaneous), 0U994ZX (percutaneous endoscopic) and 0U997ZX (via natural or artificial opening).

It is an operating-room procedure in the MS-DRG logic for DRG 744 (D&C, Conization, Laparoscopy and Tubal Interruption with CC/MCC) and DRG 745 (D&C, Conization, Laparoscopy and Tubal Interruption without CC/MCC), under the surgical category “D&C, Conization, Laparoscopy and Tubal Interruption”.

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