About 02894ZZ

02894ZZ is the ICD-10-PCS code for a division procedure on the chordae tendineae using a percutaneous endoscopic 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 02884ZZ (conduction mechanism) and 028D4ZZ (papillary muscle).

The same procedure with a different approach is coded 02890ZZ (open) and 02893ZZ (percutaneous).

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.
