About 07HT4YZ

07HT4YZ is the ICD-10-PCS code for a insertion procedure on the bone marrow using a percutaneous endoscopic approach with other 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.

For a different body part, codes include 07HK4YZ (thoracic duct), 07HL4YZ (cisterna chyli), 07HM4YZ (thymus), 07HN4YZ (lymphatic) and 07HP4YZ (spleen).

The same procedure with a different approach is coded 07HT0YZ (open) and 07HT3YZ (percutaneous).

With a different device, use 07HT41Z (radioactive element) and 07HT43Z (infusion 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.
