About 0UB10ZZ

0UB10ZZ is the ICD-10-PCS code for a excision procedure on the left ovary using an open approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to wedge resection of ovary, the ICD-9-CM procedure title it maps to (65.22).

For a different body part, codes include 0UB00ZZ (right ovary), 0UB20ZZ (bilateral ovaries), 0UB40ZZ (uterine supporting structure), 0UB50ZZ (right fallopian tube), 0UB60ZZ (left fallopian tube), 0UB70ZZ (bilateral fallopian tubes) and 8 more.

The same procedure with a different approach is coded 0UB13ZZ (percutaneous), 0UB14ZZ (percutaneous endoscopic), 0UB17ZZ (via natural or artificial opening) and 0UB18ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 628 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 629 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with CC), DRG 630 (Other Endocrine, Nutritional and Metabolic O.R. Procedures without CC/MCC), DRG 731 (Uterine and Adnexa Procedures for Malignancy with MCC), DRG 732 (Uterine and Adnexa Procedures for Malignancy with CC) and DRG 733 (Uterine and Adnexa Procedures for Malignancy without CC/MCC), under the surgical categories “Other Endocrine, Nutritional and Metabolic O.R. Procedures”, “Uterine and Adnexa Procedures for Malignancy” and “Uterine and Adnexa Procedures for Non-Malignancy”.

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