About 08933ZX

08933ZX is the ICD-10-PCS code for a drainage procedure on the left anterior chamber using a percutaneous 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 diagnostic aspiration of anterior chamber of eye, the ICD-9-CM procedure title it maps to (12.21).

For a different body part, codes include 08923ZX (right anterior chamber), 08943ZX (right vitreous), 08953ZX (left vitreous), 089A3ZX (right choroid), 089B3ZX (left choroid), 089C3ZX (right iris) and 17 more.

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.
