About 02TH0ZZ

02TH0ZZ is the ICD-10-PCS code for a resection procedure on the pulmonary valve using an open approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to other operations on valves of heart, the ICD-9-CM procedure title it maps to (35.99).

For a different body part, codes include 02T50ZZ (atrial septum), 02T80ZZ (conduction mechanism), 02T90ZZ (chordae tendineae), 02TD0ZZ (papillary muscle), 02TM0ZZ (ventricular septum) and 02TN0ZZ (pericardium).

The same procedure with a different approach is coded 02TH3ZZ (percutaneous) and 02TH4ZZ (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.
