About 0899X0Z

0899X0Z is the ICD-10-PCS code for a drainage procedure on the left cornea using an external 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 incision of cornea, the ICD-9-CM procedure title it maps to (11.1).

For a different body part, codes include 0890X0Z (right eye), 0891X0Z (left eye), 0896X0Z (right sclera), 0897X0Z (left sclera), 0898X0Z (right cornea), 089NX0Z (right upper eyelid) and 5 more.

With a different device, use 0899XZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 116 (Intraocular Procedures with CC/MCC), DRG 117 (Intraocular Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC), DRG 909 (Other O.R. Procedures for Injuries without CC/MCC) and DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), under the surgical categories “Intraocular Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
