About 059400Z
059400Z is the ICD-10-PCS code for a drainage procedure on the left innominate vein using an open approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to venous cutdown, the ICD-9-CM procedure title it maps to (38.94).
For a different body part, codes include 059000Z (azygos vein), 059100Z (hemiazygos vein), 059300Z (right innominate vein), 059500Z (right subclavian vein), 059600Z (left subclavian vein), 059700Z (right axillary vein) and 19 more.
The same procedure with a different approach is coded 059430Z (percutaneous) and 059440Z (percutaneous endoscopic).
With a different device, use 05940ZZ (no device).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
