About 07HM33Z
07HM33Z is the ICD-10-PCS code for a insertion procedure on the thymus using a percutaneous approach with infusion 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 other miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).
For a different body part, codes include 07HK33Z (thoracic duct), 07HL33Z (cisterna chyli), 07HN33Z (lymphatic), 07HP33Z (spleen) and 07HT33Z (bone marrow).
The same procedure with a different approach is coded 07HM03Z (open) and 07HM43Z (percutaneous endoscopic).
With a different device, use 07HM31Z (radioactive element) 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 has been valid since ICD-10-PCS took effect on October 1, 2015.
