About 02TN0ZZ
02TN0ZZ is the ICD-10-PCS code for a resection procedure on the pericardium 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 Pericardiectomy, the ICD-9-CM procedure title it maps to (37.31).
For a different body part, codes include 02T50ZZ (atrial septum), 02T80ZZ (conduction mechanism), 02T90ZZ (chordae tendineae), 02TD0ZZ (papillary muscle), 02TH0ZZ (pulmonary valve) and 02TM0ZZ (ventricular septum).
The same procedure with a different approach is coded 02TN3ZZ (percutaneous) and 02TN4ZZ (percutaneous endoscopic).
It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC), DRG 165 (Major Chest Procedures without CC/MCC), DRG 270 (Other Major Cardiovascular Procedures with MCC), DRG 271 (Other Major Cardiovascular Procedures with CC) and DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), under the surgical categories “Major Chest Procedures”, “Other Major Cardiovascular Procedures”, “Lymphoma and Leukemia with Major O.R. Procedures” and 3 more.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
