About 0JH638Z

0JH638Z is the ICD-10-PCS code for a insertion procedure on the subcutaneous tissue and fascia, chest using a percutaneous approach with defibrillator generator. 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 implantation of automatic cardioverter/defibrillator pulse generator only, the ICD-9-CM procedure title it maps to (37.96).

For a different body part, codes include 0JH838Z (subcutaneous tissue and fascia, abdomen).

The same procedure with a different approach is coded 0JH608Z (open).

With a different device, use 0JH630Z (monitoring device, hemodynamic), 0JH632Z (monitoring device), 0JH634Z (pacemaker, single chamber), 0JH635Z (pacemaker, single chamber rate responsive), 0JH636Z (pacemaker, dual chamber), 0JH637Z (cardiac resynchronization pacemaker pulse generator) and 15 more.

It is an operating-room procedure in the MS-DRG logic for DRG 245 (AICD Generator Procedures) and DRG 275 (Cardiac Defibrillator Implant with Cardiac Catheterization and MCC), under the surgical categories “AICD Generator Procedures” and “Cardiac Defibrillator Implant with Cardiac Catheterization”.

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