About 04BF4ZX

04BF4ZX is the ICD-10-PCS code for a excision procedure on the left internal iliac artery using a percutaneous endoscopic 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 04B04ZX (abdominal aorta), 04B14ZX (celiac artery), 04B24ZX (gastric artery), 04B34ZX (hepatic artery), 04B44ZX (splenic artery), 04B54ZX (superior mesenteric artery) and 24 more.

The same procedure with a different approach is coded 04BF0ZX (open) and 04BF3ZX (percutaneous).

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.
