About 02890ZZ

02890ZZ is the ICD-10-PCS code for a division procedure on the chordae tendineae using an open approach. In ICD-10-PCS, division means cutting into a body part, without draining fluids and/or gases from the body part, in order to separate or transect a body part.

In plain terms, this corresponds to operations on chordae tendineae, the ICD-9-CM procedure title it maps to (35.32).

For a different body part, codes include 02880ZZ (conduction mechanism) and 028D0ZZ (papillary muscle).

The same procedure with a different approach is coded 02893ZZ (percutaneous) and 02894ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 228 (Other Cardiothoracic Procedures with MCC) and DRG 229 (Other Cardiothoracic Procedures without MCC), under the surgical category “Other Cardiothoracic Procedures”.

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