About 08WM0YZ

08WM0YZ is the ICD-10-PCS code for a revision procedure on the left extraocular muscle using an open approach with other device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

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 08W00YZ (right eye), 08W10YZ (left eye) and 08WL0YZ (right extraocular muscle).

The same procedure with a different approach is coded 08WM3YZ (percutaneous).

With a different device, use 08WM00Z (drainage device), 08WM07Z (autologous tissue substitute), 08WM0JZ (synthetic substitute) and 08WM0KZ (nonautologous tissue substitute).

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 was added in FY2018, effective October 1, 2017.
