About 089L0ZZ
089L0ZZ is the ICD-10-PCS code for a drainage procedure on the right extraocular muscle using an open approach. 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 extraocular muscles and tendons, the ICD-9-CM procedure title it maps to (15.9).
For a different body part, codes include 089A0ZZ (right choroid), 089B0ZZ (left choroid), 089M0ZZ (left extraocular muscle), 089N0ZZ (right upper eyelid), 089P0ZZ (left upper eyelid), 089Q0ZZ (right lower eyelid) and 5 more.
The same procedure with a different approach is coded 089L3ZZ (percutaneous).
With a different device, use 089L00Z (drainage device).
It is an operating-room procedure in the MS-DRG logic for DRG 115 (Extraocular Procedures Except Orbit), 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), DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC) and DRG 958 (Other O.R. Procedures for Multiple Significant Trauma with CC), under the surgical categories “Extraocular Procedures Except Orbit”, “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.
