About 0JH635Z

0JH635Z is the ICD-10-PCS code for a insertion procedure on the subcutaneous tissue and fascia, chest using a percutaneous approach with pacemaker, single chamber rate responsive. 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 initial insertion of single-chamber device, rate responsive, the ICD-9-CM procedure title it maps to (37.82).

For a different body part, codes include 0JH835Z (subcutaneous tissue and fascia, abdomen).

The same procedure with a different approach is coded 0JH605Z (open).

With a different device, use 0JH630Z (monitoring device, hemodynamic), 0JH632Z (monitoring device), 0JH634Z (pacemaker, single chamber), 0JH636Z (pacemaker, dual chamber), 0JH637Z (cardiac resynchronization pacemaker pulse generator), 0JH638Z (defibrillator generator) and 15 more.

It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 210 (Cardiac Pacemaker Revision or Device Replacement with MCC), DRG 211 (Cardiac Pacemaker Revision or Device Replacement without MCC), DRG 242 (Permanent Cardiac Pacemaker Implant with MCC), DRG 243 (Permanent Cardiac Pacemaker Implant with CC) and DRG 244 (Permanent Cardiac Pacemaker Implant without CC/MCC), under the surgical categories “Cardiac Pacemaker Revision or Device Replacement” and “Permanent Cardiac Pacemaker Implant”.

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