About Y77.11

Y77.11 is the ICD-10-CM diagnosis code for contact lens associated with adverse incidents. It belongs to category Y77 (ophthalmic devices associated with adverse incidents), block Y70-Y82 (medical devices associated with adverse incidents in diagnostic and therapeutic use) and chapter 20 (external causes of morbidity). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Y77.1 (therapeutic (nonsurgical) and rehabilitative ophthalmic devices associated with adverse incidents), Y77.11 is specifically for contact lens associated with adverse incidents. Related codes cover other therapeutic (nonsurgical) and rehabilitative ophthalmic devices associated with adverse incidents (Y77.19).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

It was added in FY2021, effective October 1, 2020.
