Does Medicare Cover Glaucoma Treatment in 2026?
Yes — does Medicare cover glaucoma treatment in 2026 — and the answer is a comprehensive yes across the full spectrum of glaucoma care. Medicare Part B covers glaucoma screening for high-risk beneficiaries at $0, diagnostic testing including visual field testing and OCT imaging at 80% after the deductible, physician visits for glaucoma management, laser treatments, and surgical procedures. Medicare Part D covers glaucoma medications including prescription eye drops.
Glaucoma affects approximately 3 million Americans and disproportionately affects older adults — making it one of the most important eye conditions in the Medicare population. Glaucoma is called the silent thief of sight because it causes gradual vision loss with few symptoms until significant damage has occurred. Regular screening and ongoing treatment are essential for preventing blindness — and Medicare’s comprehensive glaucoma coverage ensures financial barriers never prevent beneficiaries from accessing this vision-preserving care.
The question does Medicare cover glaucoma treatment is particularly important because glaucoma requires lifelong management — unlike some conditions that are treated once and resolved. Medicare beneficiaries with glaucoma need ongoing monitoring, medication, and sometimes repeated laser treatments or surgery over many years of management.
Does Medicare Cover Glaucoma Screening?
Does Medicare cover glaucoma screening in 2026? Yes — Medicare Part B covers annual glaucoma screening at $0 — no deductible and no coinsurance — for Medicare beneficiaries who are at high risk for glaucoma.
Who Qualifies for Free Glaucoma Screening
Medicare covers the annual $0 glaucoma screening for beneficiaries in any of the following high-risk groups:
- People with diabetes — diabetes significantly increases glaucoma risk
- People with a family history of glaucoma
- African Americans aged 50 and older — who have significantly higher glaucoma risk
- Hispanic Americans aged 65 and older — who have elevated glaucoma risk
What the Glaucoma Screening Includes
The Medicare-covered glaucoma screening includes:
- Intraocular pressure measurement — tonometry to detect elevated eye pressure
- Optic nerve evaluation
- Visual field screening when indicated
Who Performs the Screening
The Medicare-covered glaucoma screening must be performed by an eye doctor — ophthalmologist or optometrist — who is legally authorized to perform glaucoma examinations in your state.
When Glaucoma Screening Is Not at $0
For Medicare beneficiaries who do not fall into the high-risk categories glaucoma screening is not covered at $0 as a preventive service. However when a physician orders glaucoma testing as a medically necessary diagnostic test — for example when glaucoma is suspected based on symptoms or examination findings — the testing is covered at 80% after the Part B deductible.
Does Medicare Cover Glaucoma Diagnostic Testing?
Does Medicare cover glaucoma diagnostic testing in 2026? Yes — Medicare Part B covers comprehensive glaucoma diagnostic testing at 80% after the $257 annual Part B deductible when medically ordered.
Visual Field Testing — Covered
Visual field testing — perimetry — is the essential test for monitoring glaucoma progression by mapping areas of vision loss. Medicare covers visual field testing at 80% after the deductible. Most glaucoma patients require visual field testing every 6 to 12 months for ongoing monitoring.
OCT Imaging — Covered
Optical coherence tomography (OCT) imaging of the optic nerve and retinal nerve fiber layer is covered by Medicare at 80% after the deductible. OCT provides detailed images of the optic nerve to detect glaucoma progression — covered as a medically necessary diagnostic service.
Gonioscopy — Covered
Gonioscopy — examination of the drainage angle of the eye — is covered by Medicare as part of glaucoma evaluation.
Pachymetry — Covered
Corneal thickness measurement — pachymetry — which helps assess glaucoma risk is covered by Medicare when medically ordered.
Ophthalmologist Visits — Covered
Medicare Part B covers ophthalmologist and optometrist visits for glaucoma management at 80% after the Part B deductible. Regular monitoring visits — typically every 3 to 6 months for glaucoma patients — are covered as medically necessary physician services.
Does Medicare Cover Glaucoma Medications?
Does Medicare cover glaucoma medications in 2026? Yes — Medicare Part D covers prescription glaucoma medications — the eye drops used to lower intraocular pressure and prevent optic nerve damage.

Medicare covers SLT at 80% after the Part B deductible. SLT can often replace or reduce reliance on daily eye drops and may need to be repeated every 3 to 5 years. Each course of SLT is covered as a medically necessary procedure.
Argon Laser Trabeculoplasty (ALT) — Covered
ALT — the predecessor to SLT — is also covered by Medicare at 80% after the deductible.
Laser Peripheral Iridotomy (LPI) — Covered

Cyclophotocoagulation — Covered
Laser cyclophotocoagulation — used for refractory glaucoma — is covered by Medicare at 80% after the deductible.
Laser Treatment Costs with Medicare
Typical Medicare-approved amounts for glaucoma laser procedures:
