About 0U164Z9

0U164Z9 is the ICD-10-PCS code for a bypass procedure on the left fallopian tube using a percutaneous endoscopic approach (qualifier: uterus). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.

In plain terms, this corresponds to Salpingo-uterostomy, the ICD-9-CM procedure title it maps to (66.74).

For a different body part, codes include 0U154Z9 (right fallopian tube).

The same procedure with a different approach is coded 0U160Z9 (open).

With a different device, use 0U16479 (autologous tissue substitute), 0U164J9 (synthetic substitute) and 0U164K9 (nonautologous tissue substitute).

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.
