About 02H70YZ
02H70YZ is the ICD-10-PCS code for a insertion procedure on the left atrium using an open approach with other device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part.
In plain terms, this corresponds to other repair of heart and pericardium, the ICD-9-CM procedure title it maps to (37.49).
For a different body part, codes include 02H00YZ (coronary artery, one artery), 02H10YZ (coronary artery, two arteries), 02H20YZ (coronary artery, three arteries), 02H30YZ (coronary artery, four or more arteries), 02H40YZ (coronary vein), 02H60YZ (right atrium) and 11 more.
The same procedure with a different approach is coded 02H73YZ (percutaneous) and 02H74YZ (percutaneous endoscopic).
With a different device, use 02H700Z (monitoring device, pressure sensor), 02H702Z (monitoring device), 02H703Z (infusion device), 02H70DZ (intraluminal device), 02H70JZ (cardiac lead, pacemaker), 02H70KZ (cardiac lead, defibrillator) and 2 more.
It is an operating-room procedure in the MS-DRG logic for DRG 361 (Other Circulatory System O.R. Procedures with MCC) and DRG 362 (Other Circulatory System O.R. Procedures without MCC), under the surgical category “Other Circulatory System O.R. Procedures”.
