About 02T84ZZ

02T84ZZ is the ICD-10-PCS code for a resection procedure on the conduction mechanism using a percutaneous endoscopic approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to excision or destruction of other lesion or tissue of heart, thoracoscopic approach, the ICD-9-CM procedure title it maps to (37.37).

For a different body part, codes include 02T54ZZ (atrial septum), 02T94ZZ (chordae tendineae), 02TD4ZZ (papillary muscle), 02TH4ZZ (pulmonary valve), 02TM4ZZ (ventricular septum) and 02TN4ZZ (pericardium).

The same procedure with a different approach is coded 02T80ZZ (open) and 02T83ZZ (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.
