About 07HM31Z

07HM31Z is the ICD-10-PCS code for a insertion procedure on the thymus using a percutaneous approach with radioactive element. 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.

For a different body part, codes include 07HK31Z (thoracic duct), 07HL31Z (cisterna chyli), 07HN31Z (lymphatic), 07HP31Z (spleen) and 07HT31Z (bone marrow).

The same procedure with a different approach is coded 07HM01Z (open) and 07HM41Z (percutaneous endoscopic).

With a different device, use 07HM33Z (infusion device) and 07HM3YZ (other device).

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

It was added in FY2021, effective October 1, 2020.
