About 02HN42Z

02HN42Z is the ICD-10-PCS code for a insertion procedure on the pericardium using a percutaneous endoscopic approach with monitoring 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 Pericardiotomy, the ICD-9-CM procedure title it maps to (37.12).

For a different body part, codes include 02H442Z (coronary vein), 02H642Z (right atrium), 02H742Z (left atrium), 02HK42Z (right ventricle), 02HL42Z (left ventricle), 02HP42Z (pulmonary trunk) and 7 more.

The same procedure with a different approach is coded 02HN02Z (open) and 02HN32Z (percutaneous).

With a different device, use 02HN40Z (monitoring device, pressure sensor), 02HN4JZ (cardiac lead, pacemaker), 02HN4KZ (cardiac lead, defibrillator), 02HN4MZ (cardiac lead) and 02HN4YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC), DRG 165 (Major Chest Procedures without CC/MCC), DRG 270 (Other Major Cardiovascular Procedures with MCC), DRG 271 (Other Major Cardiovascular Procedures with CC) and DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), under the surgical categories “Major Chest Procedures”, “Other Major Cardiovascular Procedures”, “Lymphoma and Leukemia with Major O.R. Procedures” and 3 more.

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