About 04970ZX

04970ZX is the ICD-10-PCS code for a drainage procedure on the left colic artery using an open 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 04900ZX (abdominal aorta), 04910ZX (celiac artery), 04920ZX (gastric artery), 04930ZX (hepatic artery), 04940ZX (splenic artery), 04950ZX (superior mesenteric artery) and 24 more.

The same procedure with a different approach is coded 04973ZX (percutaneous) and 04974ZX (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.
