About 02N53ZZ

02N53ZZ is the ICD-10-PCS code for a release procedure on the atrial septum 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 other operations on septa of heart, the ICD-9-CM procedure title it maps to (35.98).

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), 02N63ZZ (right atrium) and 20 more.

The same procedure with a different approach is coded 02N50ZZ (open) and 02N54ZZ (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.
