About 10T20ZZ

10T20ZZ is the ICD-10-PCS code for a resection procedure on the products of conception, ectopic using an open approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to removal of extratubal ectopic pregnancy, the ICD-9-CM procedure title it maps to (74.3).

The same procedure with a different approach is coded 10T23ZZ (percutaneous), 10T24ZZ (percutaneous endoscopic), 10T27ZZ (via natural or artificial opening) and 10T28ZZ (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.
