About 0UB50ZX

0UB50ZX is the ICD-10-PCS code for a excision procedure on the right fallopian tube using an open approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to biopsy of fallopian tube, the ICD-9-CM procedure title it maps to (66.11).

For a different body part, codes include 0UB00ZX (right ovary), 0UB10ZX (left ovary), 0UB20ZX (bilateral ovaries), 0UB40ZX (uterine supporting structure), 0UB60ZX (left fallopian tube), 0UB70ZX (bilateral fallopian tubes) and 8 more.

The same procedure with a different approach is coded 0UB53ZX (percutaneous), 0UB54ZX (percutaneous endoscopic), 0UB57ZX (via natural or artificial opening) and 0UB58ZX (via natural or artificial opening 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.
