About 02N03ZZ
02N03ZZ is the ICD-10-PCS code for a release procedure on the coronary artery, one artery 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 vessels of heart, the ICD-9-CM procedure title it maps to (36.99).
For a different body part, codes include 02N13ZZ (coronary artery, two arteries), 02N23ZZ (coronary artery, three arteries), 02N33ZZ (coronary artery, four or more arteries), 02N43ZZ (coronary vein), 02N53ZZ (atrial septum), 02N63ZZ (right atrium) and 20 more.
The same procedure with a different approach is coded 02N00ZZ (open) and 02N04ZZ (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 was added in FY2018, effective October 1, 2017.
