About 0UWMX0Z

0UWMX0Z is the ICD-10-PCS code for a revision procedure on the vulva using an external approach with drainage device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to other miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).

For a different body part, codes include 0UW3X0Z (ovary), 0UW8X0Z (fallopian tube), 0UWDX0Z (uterus and cervix) and 0UWHX0Z (vagina and cul-de-sac).

The same procedure with a different approach is coded 0UWM00Z (open).

With a different device, use 0UWMX7Z (autologous tissue substitute), 0UWMXJZ (synthetic substitute) and 0UWMXKZ (nonautologous tissue substitute).

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.
