About 0UDN0ZZ

0UDN0ZZ is the ICD-10-PCS code for a extraction procedure on the ova using an open approach. In ICD-10-PCS, extraction means pulling or stripping out or off all or a portion of a body part by the use of force.

In plain terms, this corresponds to aspiration of ovary, the ICD-9-CM procedure title it maps to (65.91).

The same procedure with a different approach is coded 0UDN3ZZ (percutaneous) and 0UDN4ZZ (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) and DRG 743 (Uterine and Adnexa Procedures for Non-Malignancy without CC/MCC), under the surgical categories “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.
