Eye Disease Is Different From Routine Vision Care
Medicare's approach to eyes confuses people because it splits sharply: routine vision care — exams for glasses, most eyewear — generally isn't covered (see dental, vision & hearing on Medicare), but treatment for eye diseases is. Glaucoma, macular degeneration, and diabetic eye disease are medical conditions, and Medicare Part B covers their diagnosis and treatment. This distinction matters enormously for the many older adults who face these sight-threatening conditions.
If you're worried about coverage for a serious eye condition, the reassuring news is that Medicare treats these as the medical issues they are. Here's what's covered.
Glaucoma Coverage
Glaucoma — increased pressure in the eye that can damage the optic nerve and cause blindness if untreated — is covered by Medicare in important ways. Medicare covers an annual glaucoma screening for people at high risk, including those with diabetes, a family history of glaucoma, African Americans over 50, and Hispanic Americans over 65. These screenings are preventive and can catch the disease early, when treatment is most effective.
Beyond screening, Medicare Part B covers the diagnosis and treatment of glaucoma — office visits, testing, and medically necessary procedures. Glaucoma medications (eye drops) are covered under Part D. You pay the standard cost-sharing, which a Medigap plan covers on the Part B side.
Macular Degeneration Coverage
Age-related macular degeneration (AMD) — a leading cause of vision loss in older adults — is also covered as a medical condition. Medicare Part B covers the diagnosis and treatment of AMD, including certain injectable drugs used to treat the 'wet' form of the disease, which are administered in a doctor's office and covered under Part B. These treatments can be expensive, which makes the coverage — and having a supplement to cover the coinsurance — genuinely important.
Because the injectable AMD treatments fall under Part B, they carry the 20% coinsurance with no cap unless you have a supplement — and for ongoing injections, that adds up. This is one more example of why comprehensive coverage matters for people with chronic medical needs, a theme throughout Medicare.
Protecting Your Vision and Your Wallet
The practical takeaways: if you're at high risk for glaucoma, use the covered annual screening — early detection protects your sight. If you have or develop macular degeneration or glaucoma, know that Medicare covers the medical treatment, and that a supplement covers the Part B coinsurance on what can be costly, ongoing care. Routine eye exams for glasses remain generally uncovered, though you have the post-cataract-surgery eyewear benefit as one exception.
For people managing serious eye conditions, the coverage details and the coinsurance exposure make the Medigap vs. Advantage decision worth thinking through carefully. We help clients understand how their coverage handles eye disease and other chronic conditions, at no cost — because protecting your vision shouldn't come with financial anxiety about whether treatment is covered.
Frequently Asked Questions
Does Medicare cover glaucoma treatment?
Yes. Medicare Part B covers glaucoma diagnosis and treatment, plus an annual glaucoma screening for high-risk people (those with diabetes, family history, and certain higher-risk groups). Glaucoma eye drops are covered under Part D.
Does Medicare cover macular degeneration treatment?
Yes. Medicare Part B covers diagnosis and treatment of age-related macular degeneration, including certain injectable drugs for the 'wet' form given in a doctor's office. These carry 20% coinsurance, which a supplement covers.
Does Medicare cover eye exams?
Only medical eye exams — for diagnosing and treating eye diseases like glaucoma and macular degeneration, or for high-risk screenings. Routine eye exams to get glasses are generally not covered, except one pair of eyewear after cataract surgery.
Are macular degeneration injections expensive with Medicare?
They can be. The injectable treatments fall under Part B with 20% coinsurance and no cap unless you have a Medicare Supplement, which covers it. For ongoing injections, having a supplement makes a significant difference in your out-of-pocket costs.
