About 085M0ZZ

085M0ZZ is the ICD-10-PCS code for a destruction procedure on the left extraocular muscle using an open approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.

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 085A0ZZ (right choroid), 085B0ZZ (left choroid), 085L0ZZ (right extraocular muscle), 085N0ZZ (right upper eyelid), 085P0ZZ (left upper eyelid), 085Q0ZZ (right lower eyelid) and 5 more.

The same procedure with a different approach is coded 085M3ZZ (percutaneous).

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.
