About 028D3ZZ

028D3ZZ is the ICD-10-PCS code for a division procedure on the papillary muscle using a percutaneous 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 papillary muscle, the ICD-9-CM procedure title it maps to (35.31).

For a different body part, codes include 02883ZZ (conduction mechanism) and 02893ZZ (chordae tendineae).

The same procedure with a different approach is coded 028D0ZZ (open) and 028D4ZZ (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.
