About 02T93ZZ

02T93ZZ is the ICD-10-PCS code for a resection procedure on the chordae tendineae using a percutaneous approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of 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 02T53ZZ (atrial septum), 02T83ZZ (conduction mechanism), 02TD3ZZ (papillary muscle), 02TH3ZZ (pulmonary valve), 02TM3ZZ (ventricular septum) and 02TN3ZZ (pericardium).

The same procedure with a different approach is coded 02T90ZZ (open) and 02T94ZZ (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.
