Though having dry eyes won’t necessarily impact your vision, it can be a painful condition that affects your quality of life. Medicare will generally cover an exam to diagnose the problem since it’s not considered “routine,” at which point you’ll be on the hook for 20% coinsurance after you’ve met your Part B. Your Part D plan might also cover medication to treat the condition, though in some cases, over-the-counter treatment will suffice. You’ll get similar coverage with a Medicare Advantage plan, and Medigap can help with your out-of-pocket costs if you have Original Medicare.
