About 02CM4ZZ
02CM4ZZ is the ICD-10-PCS code for a extirpation procedure on the ventricular septum using a percutaneous endoscopic approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.
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 02C04ZZ (coronary artery, one artery), 02C14ZZ (coronary artery, two arteries), 02C24ZZ (coronary artery, three arteries), 02C34ZZ (coronary artery, four or more arteries), 02C44ZZ (coronary vein), 02C54ZZ (atrial septum) and 20 more.
The same procedure with a different approach is coded 02CM0ZZ (open) and 02CM3ZZ (percutaneous).
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.
