About 059100Z
059100Z is the ICD-10-PCS code for a drainage procedure on the hemiazygos 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), 059300Z (right innominate vein), 059400Z (left 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 059130Z (percutaneous) and 059140Z (percutaneous endoscopic).
With a different device, use 05910ZZ (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.
