About 0899XZX

0899XZX is the ICD-10-PCS code for a drainage procedure on the left cornea using an external approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to biopsy of cornea, the ICD-9-CM procedure title it maps to (11.22).

For a different body part, codes include 0890XZX (right eye), 0891XZX (left eye), 0896XZX (right sclera), 0897XZX (left sclera), 0898XZX (right cornea), 089NXZX (right upper eyelid) and 5 more.

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.
