About 0UM20ZZ

0UM20ZZ is the ICD-10-PCS code for a reattachment procedure on the bilateral ovaries using an open approach. In ICD-10-PCS, reattachment means putting back in or on all or a portion of a separated body part to its normal location or other suitable location.

In plain terms, this corresponds to other reimplantation of ovary, the ICD-9-CM procedure title it maps to (65.72).

For a different body part, codes include 0UM00ZZ (right ovary), 0UM10ZZ (left ovary), 0UM40ZZ (uterine supporting structure), 0UM50ZZ (right fallopian tube), 0UM60ZZ (left fallopian tube), 0UM70ZZ (bilateral fallopian tubes) and 5 more.

The same procedure with a different approach is coded 0UM24ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 731 (Uterine and Adnexa Procedures for Malignancy with MCC), DRG 732 (Uterine and Adnexa Procedures for Malignancy with CC), DRG 733 (Uterine and Adnexa Procedures for Malignancy without CC/MCC), DRG 742 (Uterine and Adnexa Procedures for Non-Malignancy with CC/MCC), DRG 743 (Uterine and Adnexa Procedures for Non-Malignancy without CC/MCC) and DRG 907 (Other O.R. Procedures for Injuries with MCC), under the surgical categories “Uterine and Adnexa Procedures for Malignancy”, “Uterine and Adnexa Procedures for Non-Malignancy”, “Other O.R. Procedures for Injuries” and 1 more.

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