About 0U778ZZ

0U778ZZ is the ICD-10-PCS code for a dilation procedure on the bilateral fallopian tubes using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to dilation of fallopian tube, the ICD-9-CM procedure title it maps to (66.96).

For a different body part, codes include 0U758ZZ (right fallopian tube), 0U768ZZ (left fallopian tube), 0U798ZZ (uterus), 0U7C8ZZ (cervix), 0U7G8ZZ (vagina) and 0U7K8ZZ (hymen).

The same procedure with a different approach is coded 0U770ZZ (open), 0U773ZZ (percutaneous), 0U774ZZ (percutaneous endoscopic) and 0U777ZZ (via natural or artificial opening).

With a different device, use 0U778DZ (intraluminal device).

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.
