About 02K80ZZ

02K80ZZ is the ICD-10-PCS code for a map procedure on the conduction mechanism using an open approach. In ICD-10-PCS, map means locating the route of passage of electrical impulses and/or locating functional areas in a body part.

In plain terms, this corresponds to cardiac mapping, the ICD-9-CM procedure title it maps to (37.27).

The same procedure with a different approach is coded 02K83ZZ (percutaneous) and 02K84ZZ (percutaneous endoscopic).

It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 273 (Percutaneous and Other Intracardiac Procedures with MCC) and DRG 274 (Percutaneous and Other Intracardiac Procedures without MCC), under the surgical category “Percutaneous and Other Intracardiac Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
