About 02NX3ZZ
02NX3ZZ is the ICD-10-PCS code for a release procedure on the thoracic aorta, ascending/arch 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 Freeing of vessel, the ICD-9-CM procedure title it maps to (39.91).
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 02NX0ZZ (open) and 02NX4ZZ (percutaneous endoscopic).
It is an operating-room procedure in the MS-DRG logic for DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical category “Other Vascular Procedures”.
It was added in FY2017, effective October 1, 2016.
