About 06940ZX

06940ZX is the ICD-10-PCS code for a drainage procedure on the hepatic vein 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 06900ZX (inferior vena cava), 06910ZX (splenic vein), 06920ZX (gastric vein), 06930ZX (esophageal vein), 06950ZX (superior mesenteric vein), 06960ZX (inferior mesenteric vein) and 17 more.

The same procedure with a different approach is coded 06943ZX (percutaneous) and 06944ZX (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.
