About 0899XZZ
0899XZZ is the ICD-10-PCS code for a drainage procedure on the left cornea using an external 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 incision of cornea, the ICD-9-CM procedure title it maps to (11.1).
For a different body part, codes include 0890XZZ (right eye), 0891XZZ (left eye), 0896XZZ (right sclera), 0897XZZ (left sclera), 0898XZZ (right cornea), 089NXZZ (right upper eyelid) and 5 more.
With a different device, use 0899X0Z (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.
