About 02NJ4ZZ
02NJ4ZZ is the ICD-10-PCS code for a release procedure on the tricuspid valve using a percutaneous endoscopic 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 closed heart valvotomy, tricuspid valve, the ICD-9-CM procedure title it maps to (35.04).
For a different body part, codes include 02N04ZZ (coronary artery, one artery), 02N14ZZ (coronary artery, two arteries), 02N24ZZ (coronary artery, three arteries), 02N34ZZ (coronary artery, four or more arteries), 02N44ZZ (coronary vein), 02N54ZZ (atrial septum) and 20 more.
The same procedure with a different approach is coded 02NJ0ZZ (open) and 02NJ3ZZ (percutaneous).
It is an operating-room procedure in the MS-DRG logic for 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 category “Other Major Cardiovascular Procedures”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
