About 02NN3ZZ

02NN3ZZ is the ICD-10-PCS code for a release procedure on the pericardium using a percutaneous approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to Pericardiotomy, the ICD-9-CM procedure title it maps to (37.12).

For a different body part, codes include 02N03ZZ (coronary artery, one artery), 02N13ZZ (coronary artery, two arteries), 02N23ZZ (coronary artery, three arteries), 02N33ZZ (coronary artery, four or more arteries), 02N43ZZ (coronary vein), 02N53ZZ (atrial septum) and 20 more.

The same procedure with a different approach is coded 02NN0ZZ (open) and 02NN4ZZ (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.
