Medicare is a federal health insurance program primarily for people age 65 and older, though some younger people with disabilities or end-stage renal disease may also enroll. The program has different parts, and understanding how they cover eye care is important when searching for an ophthalmologist. Medicare Part B covers certain eye care services, including exams to diagnose and treat diseases of the eye, such as cataracts, glaucoma, and age-related macular degeneration. However, Medicare does not cover routine eye exams for glasses or contact lenses, or the glasses and contacts themselves.

According to the Centers for Medicare & Medicaid Services, approximately 46 million people were enrolled in Original Medicare (Parts A and B) in 2023. Many of these individuals need ongoing eye care for chronic conditions. When you have Medicare, you may see any licensed ophthalmologist or optometrist in the country—there is no network restriction like you might find with some private insurance plans. However, the provider must accept Medicare assignment, which means they agree to bill Medicare directly and accept Medicare's payment as full payment for covered services.
An ophthalmologist is a medical doctor who specializes in eye care and can perform surgery, while an optometrist is trained to perform eye exams and prescribe glasses and contacts but cannot perform surgery in most states. Both types of providers can accept Medicare, and your choice depends on your specific eye care needs. If you need cataract surgery or treatment for glaucoma, you would see an ophthalmologist. For a routine vision check, either provider may be appropriate.
Practical takeaway: Before searching for a provider, determine what type of eye care you need. If you require medical treatment or surgery, look for an ophthalmologist. For routine exams, an optometrist may also work. Understanding the difference helps you narrow your search.
Medicare offers an official online tool called "Care Compare" (formerly Physician Compare) on the Medicare.gov website. This tool allows you to search for healthcare providers, including ophthalmologists, by location and specialty. You can search by entering your ZIP code and selecting "Ophthalmology" or "Optometry" as the specialty. The database shows whether providers accept Medicare assignment, their office location, phone number, and sometimes additional information about their practice.

To use Care Compare effectively, visit Medicare.gov and look for the "Care Compare" link in the provider search section. Enter your ZIP code or city and state, then refine by specialty. The results will display a list of providers in your area. Each provider listing includes their National Provider Identifier (NPI), which is a unique 10-digit number assigned to all healthcare providers. You can use this number if you need to verify a provider's credentials independently.
The tool displays whether a provider "accepts Medicare assignment" with a yes or no answer. Providers who accept assignment agree to charge only what Medicare allows and cannot bill you for the difference if Medicare covers the service. If a provider does not accept assignment, they may be able to charge you more than the Medicare-approved amount, though they must still follow certain billing rules. This information helps you understand your potential out-of-pocket costs before making an appointment.
Care Compare also shows patient rating information in some cases, based on voluntary surveys about communication, respect, and courtesy. While this data comes directly from patient feedback, the sample sizes vary by provider. Some providers may have hundreds of ratings while others have only a few. You can view this feedback along with demographic information about each practice.
Practical takeaway: Start your search on Medicare.gov using Care Compare. Write down the names, phone numbers, and Medicare assignment status of at least three providers in your area so you can compare your options before calling.
While the Care Compare tool provides helpful information, calling providers directly is an important step. The database may not reflect very recent changes in a practice's Medicare status, and speaking with staff can answer additional questions specific to your situation. When you call, ask whether the practice accepts Medicare assignment and whether they are currently accepting new Medicare patients. Some practices may show as accepting Medicare in the database but may have temporarily stopped accepting new patients due to high demand.

When calling an ophthalmology practice, you may reach a scheduling coordinator or patient services representative. Have your Medicare card or member ID number available. Prepare to answer questions about the reason for your visit and any previous eye care records you have. If you have specific concerns—such as needing an appointment quickly or requiring specific services like cataract surgery—mention these during your call so staff can determine whether your needs match what the practice offers.
Ask these specific questions when you call: Does the practice accept Medicare? Do they accept Medicare assignment? Are they currently accepting new Medicare patients? What is the typical wait time for an appointment? Do they require any paperwork before your visit? What should you bring to your appointment? Do they offer any vision correction services or only medical eye care? Are there any copayments or coinsurance costs you should know about?
Some practices may ask whether you have supplemental insurance (sometimes called Medigap insurance) or Medicare Advantage coverage. This information helps them understand your coverage and explain your potential costs. If you have Medigap, many plans cover Medicare copayments, which reduces your out-of-pocket expenses. If you have Medicare Advantage, you need to verify that the provider is in-network with your specific plan.
Practical takeaway: Call at least two or three providers from your Care Compare search to compare their availability, Medicare assignment status, and office policies. Write down the information so you can make an informed decision.
When you see an ophthalmologist who accepts Medicare assignment, your costs are limited to Medicare copayments and coinsurance. For 2024, Medicare Part B has a $240 annual deductible, which you must pay before Medicare coverage begins. After you meet your deductible, you typically pay 20% of the Medicare-approved amount for covered eye care services, and Medicare pays the remaining 80%. The provider cannot bill you for more than this amount if they accept assignment.

For example, if you have a comprehensive eye exam to diagnose and treat a medical eye condition (such as glaucoma screening), the Medicare-approved amount might be around $100 to $150 depending on your location. You would pay 20% of that amount, or roughly $20 to $30 after your deductible is met. If you need cataract surgery, the costs are higher, but the same percentage rules apply. The exact amount you pay depends on the specific procedure and your local Medicare-approved amounts.
It's important to understand that Medicare does not cover routine vision exams performed solely for the purpose of prescribing glasses or contact lenses. If you need glasses but have no medical eye disease, you would pay out-of-pocket for that exam. However, if you have diabetes or glaucoma and need an exam to check for complications, that exam would be covered by Medicare. The reason for the exam determines whether it's covered.
If you have Medigap supplemental insurance, your coverage of the 20% coinsurance depends on which Medigap plan you have. Most Medigap plans cover at least part of your coinsurance after you meet your deductible. If you have Medicare Advantage instead of Original Medicare with Medigap, your eye care costs may differ because Medicare Advantage plans have their own copayment and coinsurance structures, and you must use in-network providers (except in emergencies).
Practical takeaway: Before your appointment, understand whether your deductible has been met this year and what your coinsurance percentage is. If you have Medigap or Medicare Advantage, review your plan documents to know your expected out-of-pocket costs for eye care.
Beyond basic information about Medicare acceptance, you may want to find providers who offer specific services. Some ophthalmology practices specialize in certain areas such as cataract surgery, glaucoma treatment, retinal diseases, or cornea conditions. If you need a specific treatment, you may want to search for providers with that expertise. Care Compare does not always provide detailed information about a provider's subspecialties, so additional research may be needed.
