About 089A0ZX

089A0ZX is the ICD-10-PCS code for a drainage procedure on the right choroid using an open 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 other diagnostic procedures on retina, choroid, vitreous, and posterior chamber, the ICD-9-CM procedure title it maps to (14.19).

For a different body part, codes include 089B0ZX (left choroid), 089L0ZX (right extraocular muscle), 089M0ZX (left extraocular muscle), 089N0ZX (right upper eyelid), 089P0ZX (left upper eyelid), 089Q0ZX (right lower eyelid) and 5 more.

The same procedure with a different approach is coded 089A3ZX (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 116 (Intraocular Procedures with CC/MCC) and DRG 117 (Intraocular Procedures without CC/MCC), under the surgical category “Intraocular Procedures”.

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