Does Medicare Cover Glaucoma Screenings?

Yes—Medicare Part B does cover glaucoma screenings, but only under specific conditions. Coverage is limited to individuals considered “high risk” for developing glaucoma, not the general population. This distinction is critical, as glaucoma is a leading cause of irreversible blindness, yet it often progresses silently until significant vision loss has already occurred. More than 3 million Americans are currently living with glaucoma, and researchers estimate that half of them remain unaware of their condition because early stages have no obvious symptoms.

High-risk categories include people with diabetes, those with a family history of glaucoma, African Americans aged 50 and older, and Hispanic Americans aged 65 and older. For eligible patients, Medicare pays 80% of the Medicare-approved amount for screenings after the Part B deductible of $257 in 2025, leaving the remaining 20% as coinsurance.

The sections ahead explain exactly who qualifies, what screenings include, how much patients pay, and what alternatives exist for those who do not meet Medicare’s high-risk criteria.

Understanding Medicare's High-Risk Glaucoma Coverage

Medicare’s glaucoma screening benefit is not available to everyone—it applies only to those who fall into a high risk group. That means eligibility depends on your health history, demographics, and documented risk factors. This limitation reflects Medicare’s position that glaucoma screenings are preventive services meant for patients most likely to develop the disease, not for routine vision care. Understanding these criteria is the first step toward determining if Medicare will pay for your screening test for glaucoma.

Who Qualifies as "High Risk" for Medicare Coverage

The medical qualifications for a Medicare-covered glaucoma screening are narrowly defined. People with diabetes mellitus are automatically eligible, and those with a family history of glaucoma—especially when a parent or sibling has been diagnosed—also qualify. In addition, African Americans age 50 and over and Hispanics age 65 and over qualify by demographic criteria. Other risk factors (for example, ocular hypertension, severe myopia, retinal detachment, or prior eye injury) may warrant diagnostic evaluation but do not by themselves qualify for the covered screening benefit.

High-Risk Eligibility Snapshot

Demographics also matter. African Americans age 50 and over fall into Medicare’s high risk category due to their elevated rates of glaucoma-related vision loss. Similarly, Hispanics age 65 and over qualify. However, age alone is not enough to secure coverage for non-Hispanic white patients, even though glaucoma risk rises with age. To activate coverage, your ophthalmologist or optometrist must document the qualifying risk factor in your medical record and use the appropriate HCPCS codes G0117 or G0118 when billing the screening.

• African Americans age 50 and over and Hispanics age 65 and over qualify by demographic criteria
• People with diabetes or a family history of glaucoma automatically meet high-risk status
• Medical record documentation is required for coverage under Medicare Part B

Together, these medical and demographic qualifications form the backbone of Medicare’s high-risk screening criteria, ensuring coverage is directed to those with the greatest likelihood of developing glaucoma.

What Medicare's Glaucoma Screening Includes

For those who qualify, Medicare covers a comprehensive set of glaucoma screening components. A standard screening includes intraocular pressure measurements (tonometry) and a dilated eye exam with either direct ophthalmoscopy or slit-lamp biomicroscopy to evaluate the optic nerve. Your eye doctor—either an optometrist or ophthalmologist legally authorized in your state—also performs a direct optic nerve evaluation for signs of damage.

Screening vs. Diagnostic Tests

Advanced testing may be covered when medically necessary. These can include optical coherence tomography (OCT), gonioscopy to examine the eye’s drainage angle, and optic nerve photography to establish a baseline for comparison. Additional pressure readings and specialized tests may be ordered based on findings. Altogether, these services provide a thorough assessment of glaucoma risk and allow Medicare to pay for preventive services that can prevent blindness.

• Standard components: dilated eye exam with intraocular pressure measurement plus direct ophthalmoscopy or slit-lamp biomicroscopy of the optic nerve
• If more testing is needed: visual field (perimetry), OCT, gonioscopy, and optic nerve photography may be ordered as diagnostic services based on screening findings
• Services must be performed by a qualified doctor enrolled in Medicare

These combined measures give high-risk patients access to comprehensive glaucoma testing, helping detect disease early while costs remain manageable under Medicare coverage.

Medicare Part B Coverage Details and Costs

Medicare Part B covers glaucoma screening only for beneficiaries who meet high-risk criteria, and the financial side of this coverage is important for patients to understand. Unlike Medicare Part A inpatient hospital costs, which relate to hospital stays, glaucoma screening is billed under outpatient medical services. Beneficiaries are responsible for both the Part B annual deductible and coinsurance once the deductible has been met. This means even preventive services may create some out-of-pocket cost.

Medicare Parts and Glaucoma Care at a Glance

Cost Breakdown for Qualified Patients

When a qualified patient undergoes a screening, the first charge applied is the Medicare Part B deductible, which is $257 in 2025. After that deductible is satisfied, Medicare covers 80% of the Medicare-approved amount. Patients then pay 20% coinsurance of the Medicare-approved amount (which varies by locality and setting). If the screening is performed in a hospital outpatient department, additional facility fees or an outpatient surgery copayment may apply. Patients can lower costs by choosing providers who accept Medicare assignment, which means they agree not to bill beyond Medicare-approved costs.

• Part B deductible of $257 applies in 2025
• Patients pay 20% coinsurance after deductible
• Additional copayments may apply in hospital outpatient settings

These amounts represent typical out-of-pocket costs, though supplemental coverage like a Medigap plan can reduce expenses further.

Coverage Limitations and Exclusions

Medicare limits coverage to one glaucoma screening every 12 months for high-risk individuals (at least 11 full months after the month of the last covered screening). Screenings outside this interval, or for people not meeting high-risk qualifications, are not covered. In addition, Medicare does not pay for routine eye examinations, vision correction with eyeglasses or contact lenses, or preventive interventions for patients not yet diagnosed. Medicare Advantage (Part C) plans may impose prior authorization requirements, so patients should confirm with their insurer before scheduling.

Frequency and Limitations

These coverage rules help define the boundaries of Medicare’s preventive glaucoma benefit.

• Routine vision exams and average-risk screenings are excluded
• More than one screening per 12 months is not covered
• Vision correction devices and preventive treatments are outside Medicare’s scope

Understanding these restrictions helps avoid surprise bills and clarifies when patients may need to consider private or supplemental coverage.

Glaucoma Treatment Coverage Beyond Screening

If a screening suggests glaucoma, Medicare extends coverage into diagnostic and treatment services. This shift reflects the difference between preventive services and medically necessary care. Patients move from screening test for glaucoma benefits into diagnostic and therapeutic categories, which are billed differently under Medicare Part B and, in some cases, Medicare Part D.

Diagnostic and Treatment Services Covered

Follow-up diagnostic care charges may include repeat visual field testing, optical coherence tomography, and other imaging studies to establish a diagnosis. Referrals to glaucoma specialists are covered, and Medicare pays for monitoring exams to assess disease progression. Treatment options such as laser therapies (trabeculoplasty, iridotomy), outpatient glaucoma surgery, or surgical drainage device implantation are included under Part B. Post-operative care and emergency interventions for acute angle-closure glaucoma are also covered.

• Medicare covers outpatient laser and surgical treatments for glaucoma
• Regular follow-up visits and imaging are included when medically necessary
• Post-surgical and emergency glaucoma care fall under Part B benefits

Together, these services form a continuum of care from diagnosis through long-term management.

Prescription Drug Coverage Through Medicare Part D

Because Part B does not cover prescription medications, glaucoma drugs are handled through Medicare Part D or Medicare Advantage plans that include drug coverage. Beneficiaries rely on formularies that list covered medications, which usually include eye drops such as prostaglandin analogs and beta-blockers, as well as oral drugs when needed.

• Coverage depends on the plan’s formulary and may require prior authorization
• Copayment and deductible amounts vary between generic and brand-name drugs
• Step therapy rules may require trying lower-cost medications first

Part D coverage ensures beneficiaries can afford long-term glaucoma control through medications.

Medicare Advantage Plans and Enhanced Vision Benefits

Medicare Advantage must provide at least the same glaucoma screening coverage as Original Medicare. These health maintenance organizations (HMOs) or preferred provider organizations (PPOs) often deliver additional benefits. Beneficiaries should weigh differences among Medicare parts and plans before deciding. For a practical primer, see Making the Most of Medicare Advantage.

Standard vs. Enhanced Coverage

All Medicare Advantage plans must cover one annual glaucoma screening for patients in the high risk group. Coverage still requires a qualified eye doctor within the plan’s network, and out-of-network services may be denied or billed at higher rates. However, Advantage plans frequently enhance vision benefits, such as routine eye exams for average-risk patients, eyeglass or contact lens allowances, or broader testing coverage.

• Advantage plans may cover more than Medicare’s minimum vision services
• Fixed copays sometimes replace 20% coinsurance obligations
• Expanded benefits can include coverage for additional eye care

This expanded vision care may appeal to beneficiaries who want coverage beyond Medicare’s preventive services.

Choosing Medicare Advantage for Vision Care

When evaluating Medicare Advantage plans, patients should compare not just glaucoma coverage but the overall vision package. The right plan depends on network adequacy, copayment structures, and formulary coverage for glaucoma medications.

• Confirm in-network status for preferred ophthalmologists or optometrists
• Compare deductibles, copayments, and out-of-pocket maximums
• Review prescription drug coverage for glaucoma medications

Enrollment timing also matters—most changes are allowed only during annual open enrollment from October 15 to December 7.

Alternative Options for Non-Qualifying Individuals

Because Medicare does not cover routine glaucoma screening for average-risk individuals, many patients need alternatives. Out-of-pocket cost can be a concern, but there are multiple coverage and community-based resources that can reduce the burden.

Coverage Options for Average-Risk Individuals

Private vision insurance is the most direct alternative. Standalone vision plans or employer-sponsored benefits often cover annual eye exams, including glaucoma testing for all members regardless of risk. Vision service plans may also offer discounted rates for exams. In addition, flexible spending accounts allow patients to pay exam costs with pre-tax dollars. For those without insurance, community health centers, charitable groups, and academic optometry clinics sometimes provide sliding-scale or reduced-cost exams.

• Private vision plans and employer-sponsored benefits often include glaucoma screening
• Community and nonprofit resources can provide reduced-cost or free exams
• Academic institutions and retail vision chains may offer lower-cost alternatives

These resources broaden access to glaucoma detection for people not covered under Medicare’s rules.

Self-Pay Considerations

Some patients may choose to pay directly for exams. While costs vary, shopping among providers and seeking bundled packages can lower the expense. Regular screening remains important, since glaucoma-related vision loss is irreversible once it occurs.

• Compare prices among providers to manage costs
• Take advantage of discounts or bundled exam services
• Schedule exams regularly to catch glaucoma early despite no coverage

Paying out of pocket can be an investment in protecting long-term vision health.

Step-by-Step Guide to Getting Medicare-Covered Glaucoma Screening

Getting a glaucoma screening under Medicare requires two phases: verifying eligibility and then scheduling the exam with a qualified provider. Preparing ahead reduces delays and minimizes the risk of denied claims.

Phase 1: Eligibility Verification and Provider Selection

The first step is confirming whether you belong to a high risk group. Your physician should review your health history for qualifying conditions like diabetes, family history of glaucoma, or prior eye injury. Documentation in your medical record is key, and you will need to choose an ophthalmologist or optometrist enrolled in Medicare.

• Review medical history for qualifying risk factors
• Ask your doctor to document eligibility using correct codes
• Select a Medicare-enrolled eye care provider

Completing this verification early prevents billing disputes later.

Phase 2: Scheduling and Preparation

Once eligibility is established, you can move forward with your appointment. Patients should gather medical records, prepare medication lists, and arrange transportation in case pupil dilation affects vision after the exam. Confirming coverage and expected out-of-pocket cost with the office is also recommended.

• Schedule with a qualified, Medicare-enrolled eye care provider
• Prepare medical and medication records for the visit
• Confirm costs and bring Medicare and supplemental insurance cards

These steps help ensure your screening goes smoothly and is covered appropriately.

Common Coverage Challenges and Solutions

Even when patients meet Medicare’s high-risk criteria, coverage issues can still arise. Problems often stem from documentation, provider participation, or billing errors. Knowing these pitfalls can help you avoid unnecessary out-of-pocket cost.

Frequent Coverage Issues

Eligibility problems are among the most common barriers. If high-risk status is not clearly documented, Medicare may deny coverage. Confusion between routine eye exams and glaucoma screenings can also lead to incorrect billing. In addition, timing errors—such as attempting a screening before 12 months have passed—may result in a denial.

• High-risk status missing or not documented properly
• Routine eye exam billed instead of glaucoma screening
• Screening scheduled too soon before the 12-month window

These issues highlight the importance of documentation and clear communication.

Resolving Coverage Problems

Patients can reduce risk of denial by checking that their provider is enrolled in Medicare and accepts assignment. Keep records of your last screening date, clarify billing codes in advance, and request appeals if coverage is denied despite qualifying criteria. These proactive steps help protect your benefits.

How a Solace Healthcare Advocate Can Optimize Your Glaucoma Care

Medicare’s glaucoma coverage rules can be complicated, but Solace healthcare advocates simplify the process. They help patients confirm high-risk eligibility, verify coverage before scheduling, and find Medicare-enrolled ophthalmologists or optometrists. Advocates also guide patients through cost questions, including coinsurance and copayments, and can recommend Medicare Advantage plans with stronger vision benefits.

• Advocates schedule and coordinate appointments with eye specialists and track follow-ups
• They review medication coverage under Medicare Part D and identify lower-cost options
• They provide immediate support if coverage disputes or urgent vision issues arise

With an advocate, patients have a partner to manage both medical and financial aspects of glaucoma care.

FAQ: Frequently Asked Questions About Medicare Coverage for Glaucoma Screenings

I'm over 65 but don't have diabetes or family history. Will Medicare cover my glaucoma screening?

No. Medicare only covers glaucoma screening for high-risk individuals. Age alone doesn’t qualify, except for African Americans age 50 and older and Hispanics age 65 and older. If you don’t meet those high-risk criteria, you will need to pay out-of-pocket for the exam.

How often can I get a Medicare-covered glaucoma screening?

Medicare Part B covers glaucoma screening once every 12 months for qualifying individuals (you must wait at least 11 full months after the month of your last covered screening). If you attempt to schedule a second screening within the same year, it will not be covered. More frequent testing is only paid for if medically necessary diagnostic care is required.

What's the difference between a glaucoma screening and a routine eye exam?

A glaucoma screening is a preventive service targeted at high-risk patients. It includes dilated eye exams, intraocular pressure measurements, and optic nerve evaluation. A routine eye exam, which focuses on vision correction and overall eye health, is not covered by Medicare.

Will my Medicare Advantage plan cover glaucoma screening differently than Original Medicare?

Medicare Advantage (Part C) plans must provide at least the same coverage for glaucoma screening as Original Medicare. However, some Advantage plans may add enhanced benefits, such as routine eye exams for average-risk individuals, vision hardware allowances, or expanded glaucoma imaging. Patients should compare plan details carefully.

Will Medicare cover treatment if my glaucoma screening shows signs of disease?

Yes. Once glaucoma is suspected or diagnosed, Medicare Part B covers diagnostic testing, specialist visits, and necessary treatments like laser therapy or surgery. Medicare Part D (or Advantage plans with drug coverage) helps with prescription eye drops and oral medications.
