About 07HM01Z
07HM01Z is the ICD-10-PCS code for a insertion procedure on the thymus using an open 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 07HK01Z (thoracic duct), 07HL01Z (cisterna chyli), 07HN01Z (lymphatic), 07HP01Z (spleen) and 07HT01Z (bone marrow).
The same procedure with a different approach is coded 07HM31Z (percutaneous) and 07HM41Z (percutaneous endoscopic).
With a different device, use 07HM03Z (infusion device) and 07HM0YZ (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 628 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 629 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with CC) and DRG 630 (Other Endocrine, Nutritional and Metabolic O.R. Procedures without CC/MCC), under the surgical categories “Major Chest Procedures”, “Other Endocrine, Nutritional and Metabolic O.R. Procedures”, “Other O.R. Procedures of the Blood and Blood Forming Organs” and 4 more.
It was added in FY2021, effective October 1, 2020.
