About 02TN4ZZ

02TN4ZZ is the ICD-10-PCS code for a resection procedure on the pericardium 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 Pericardiectomy, the ICD-9-CM procedure title it maps to (37.31).

For a different body part, codes include 02T54ZZ (atrial septum), 02T84ZZ (conduction mechanism), 02T94ZZ (chordae tendineae), 02TD4ZZ (papillary muscle), 02TH4ZZ (pulmonary valve) and 02TM4ZZ (ventricular septum).

The same procedure with a different approach is coded 02TN0ZZ (open) and 02TN3ZZ (percutaneous).

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.
