About 02WA3MZ

02WA3MZ is the ICD-10-PCS code for a revision procedure on the heart using a percutaneous approach with cardiac lead. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to revision of lead [electrode], the ICD-9-CM procedure title it maps to (37.75).

The same procedure with a different approach is coded 02WA0MZ (open), 02WA4MZ (percutaneous endoscopic) and 02WAXMZ (external).

With a different device, use 02WA32Z (monitoring device), 02WA33Z (infusion device), 02WA37Z (autologous tissue substitute), 02WA38Z (zooplastic tissue), 02WA3CZ (extraluminal device), 02WA3DZ (intraluminal device) and 6 more.

It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), DRG 210 (Cardiac Pacemaker Revision or Device Replacement with MCC), DRG 211 (Cardiac Pacemaker Revision or Device Replacement without MCC) and DRG 907 (Other O.R. Procedures for Injuries with MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Cardiac Pacemaker Revision or Device Replacement”, “Other O.R. Procedures for Injuries” and 1 more.

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