About 02HQ42Z

02HQ42Z is the ICD-10-PCS code for a insertion procedure on the right pulmonary artery 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 pulmonary artery wedge monitoring, the ICD-9-CM procedure title it maps to (89.64).

For a different body part, codes include 02H442Z (coronary vein), 02H642Z (right atrium), 02H742Z (left atrium), 02HK42Z (right ventricle), 02HL42Z (left ventricle), 02HN42Z (pericardium) and 7 more.

The same procedure with a different approach is coded 02HQ02Z (open) and 02HQ32Z (percutaneous).

With a different device, use 02HQ40Z (monitoring device, pressure sensor), 02HQ43Z (infusion device), 02HQ4DZ (intraluminal device) and 02HQ4YZ (other device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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