About 0UN40ZZ

0UN40ZZ is the ICD-10-PCS code for a release procedure on the uterine supporting structure using an open approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to other repair of uterus and supporting structures, the ICD-9-CM procedure title it maps to (69.29).

For a different body part, codes include 0UN00ZZ (right ovary), 0UN10ZZ (left ovary), 0UN20ZZ (bilateral ovaries), 0UN50ZZ (right fallopian tube), 0UN60ZZ (left fallopian tube), 0UN70ZZ (bilateral fallopian tubes) and 8 more.

The same procedure with a different approach is coded 0UN43ZZ (percutaneous), 0UN44ZZ (percutaneous endoscopic) and 0UN48ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 748 (Female Reproductive System Reconstructive Procedures), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC), DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC) and DRG 958 (Other O.R. Procedures for Multiple Significant Trauma with CC), under the surgical categories “Female Reproductive System Reconstructive Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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