About 03933ZX
03933ZX is the ICD-10-PCS code for a drainage procedure on the right subclavian artery using a percutaneous approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to biopsy of blood vessel, the ICD-9-CM procedure title it maps to (38.21).
For a different body part, codes include 03903ZX (right internal mammary artery), 03913ZX (left internal mammary artery), 03923ZX (innominate artery), 03943ZX (left subclavian artery), 03953ZX (right axillary artery), 03963ZX (left axillary artery) and 23 more.
The same procedure with a different approach is coded 03930ZX (open) and 03934ZX (percutaneous endoscopic).
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.
