About 03943ZZ
03943ZZ is the ICD-10-PCS code for a drainage procedure on the left subclavian artery using a percutaneous approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to other puncture of artery, the ICD-9-CM procedure title it maps to (38.98).
For a different body part, codes include 03903ZZ (right internal mammary artery), 03913ZZ (left internal mammary artery), 03923ZZ (innominate artery), 03933ZZ (right subclavian artery), 03953ZZ (right axillary artery), 03963ZZ (left axillary artery) and 23 more.
The same procedure with a different approach is coded 03940ZZ (open) and 03944ZZ (percutaneous endoscopic).
With a different device, use 039430Z (drainage 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.
