About 059T4ZX

059T4ZX is the ICD-10-PCS code for a drainage procedure on the right face vein using a percutaneous endoscopic 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 05904ZX (azygos vein), 05914ZX (hemiazygos vein), 05934ZX (right innominate vein), 05944ZX (left innominate vein), 05954ZX (right subclavian vein), 05964ZX (left subclavian vein) and 19 more.

The same procedure with a different approach is coded 059T0ZX (open) and 059T3ZX (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.
