About 10A00ZZ

10A00ZZ is the ICD-10-PCS code for a abortion procedure on the products of conception using an open approach. In ICD-10-PCS, abortion means artificially terminating a pregnancy.

In plain terms, this corresponds to Hysterotomy to terminate pregnancy, the ICD-9-CM procedure title it maps to (74.91).

The same procedure with a different approach is coded 10A03ZZ (percutaneous), 10A04ZZ (percutaneous endoscopic), 10A07ZZ (via natural or artificial opening) and 10A08ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 770 (Abortion with D&C, Aspiration Curettage or Hysterotomy), under the surgical category “Abortion with D&C, Aspiration Curettage or Hysterotomy”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
