About 04BS3ZX

04BS3ZX is the ICD-10-PCS code for a excision procedure on the left posterior tibial artery using a percutaneous approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of 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 04B03ZX (abdominal aorta), 04B13ZX (celiac artery), 04B23ZX (gastric artery), 04B33ZX (hepatic artery), 04B43ZX (splenic artery), 04B53ZX (superior mesenteric artery) and 24 more.

The same procedure with a different approach is coded 04BS0ZX (open) and 04BS4ZX (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical category “Other Vascular Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
