About 089B00Z

089B00Z is the ICD-10-PCS code for a drainage procedure on the left choroid using an open 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 other operations on retina, choroid, and posterior chamber, the ICD-9-CM procedure title it maps to (14.9).

For a different body part, codes include 089A00Z (right choroid), 089L00Z (right extraocular muscle), 089M00Z (left extraocular muscle), 089N00Z (right upper eyelid), 089P00Z (left upper eyelid), 089Q00Z (right lower eyelid) and 5 more.

The same procedure with a different approach is coded 089B30Z (percutaneous).

With a different device, use 089B0ZZ (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.
