About 059L0ZZ
059L0ZZ is the ICD-10-PCS code for a drainage procedure on the intracranial vein using an open approach. 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 05900ZZ (azygos vein), 05910ZZ (hemiazygos vein), 05930ZZ (right innominate vein), 05940ZZ (left innominate vein), 05950ZZ (right subclavian vein), 05960ZZ (left subclavian vein) and 19 more.
The same procedure with a different approach is coded 059L3ZZ (percutaneous) and 059L4ZZ (percutaneous endoscopic).
With a different device, use 059L00Z (drainage 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.
