About 08WM3YZ

08WM3YZ is the ICD-10-PCS code for a revision procedure on the left extraocular muscle using a percutaneous 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 08W03YZ (right eye), 08W13YZ (left eye), 08WJ3YZ (right lens), 08WK3YZ (left lens) and 08WL3YZ (right extraocular muscle).

The same procedure with a different approach is coded 08WM0YZ (open).

With a different device, use 08WM30Z (drainage device), 08WM37Z (autologous tissue substitute), 08WM3JZ (synthetic substitute) and 08WM3KZ (nonautologous tissue substitute).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2018, effective October 1, 2017.
