About 05910ZZ
05910ZZ is the ICD-10-PCS code for a drainage procedure on the hemiazygos 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), 05930ZZ (right innominate vein), 05940ZZ (left innominate vein), 05950ZZ (right subclavian vein), 05960ZZ (left subclavian vein), 05970ZZ (right axillary vein) and 19 more.
The same procedure with a different approach is coded 05913ZZ (percutaneous) and 05914ZZ (percutaneous endoscopic).
With a different device, use 059100Z (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.
