    Does Medicare cover scleral lenses?

    Usually not, under Original Medicare. The law excludes eyeglasses and contact lenses, with narrow exceptions after cataract surgery and for certain prosthetic uses. Here is what Medicare's own rules say, where Medicare Advantage differs, and what to ask.

    The short answer

    Original Medicare doesn't usually cover contact lenses, including scleral lenses used to correct vision for conditions like keratoconus. The exceptions are narrow: lenses after cataract surgery or for an eye without its natural lens, and, in rare cases, a scleral lens used as a prosthetic to protect an eye with severe dry eye. Medicare Advantage plans may add vision benefits. Ask your plan and confirm the practice is a Medicare-enrolled supplier.

    Key points

    • Federal rules exclude eyeglasses and contact lenses from Original Medicare, with exceptions.
    • One pair of glasses or one set of contacts is covered after each cataract surgery with a lens implant.
    • Medicare's coverage manual allows a scleral lens as a prosthetic in rare severe dry eye cases.
    • Medicare Advantage plans may offer extra vision benefits: check yours.
    • Medicare only pays suppliers that participate in Medicare.

    The short version of the rules

    Medicare.gov says Part B “doesn’t usually cover eyeglasses or contact lenses,” and that you usually pay all costs.[1] Medicare also doesn’t cover routine eye exams or refractions for eyeglasses or contact lenses.[2]

    The reason is in federal regulation. 42 CFR 411.15 excludes eyeglasses and contact lenses, and defines the exclusion broadly to cover any device that uses one or more lenses to aid vision.[3]

    The exceptions

    The same regulation lists the exceptions:[3]

    • After cataract surgery with a lens implant: one pair of conventional eyeglasses or contact lenses after each surgery.
    • During recovery from eye surgery in which the eye’s lens was removed.
    • For an eye with no natural lens and no implant (aphakia).

    Medicare.gov describes the first as one pair of glasses with standard frames, or one set of contact lenses, after each cataract surgery that implants an intraocular lens. After you meet the Part B deductible, you pay 20% of the Medicare-approved amount.[1]

    Medicare’s coverage manual treats these lenses as prosthetic devices, because they replace the function of the eye’s natural lens.[4]

    Where scleral lenses can fit in

    Medicare’s National Coverage Determinations Manual addresses scleral lenses directly. It calls the category “scleral shell” and describes two situations:[5]

    • When an eye has become sightless and shrunken from disease, a scleral shell can act essentially as an artificial eye, and payment may be made.
    • When used with artificial tears in severe dry eye, the scleral lens can act as a protective barrier and partly substitute for failing tear glands. The manual says it “would be covered as a prosthetic device in the rare case” when used to treat dry eye.

    The manual separately says soft hydrophilic lenses used as bandages for corneal disease can be paid as a supply with a physician’s service, but that hydrophilic lenses used to correct ordinary refractive error and astigmatism in non-diseased eyes are excluded as eyeglasses.[5]

    What this means in practice:

    • Scleral lenses for vision (for example, keratoconus) are generally subject to the eyeglass exclusion.
    • Scleral lenses as a prosthetic for severe dry eye have a narrow path to coverage. Whether your lens, diagnosis, and documentation qualify is decided claim by claim.

    Private insurers’ Medicare policies can mirror this. Aetna’s policy, for example, treats contact lenses as medically necessary prosthetics for its Medicare members after cataract surgery, citing the CMS definition of these lenses as prostheses.[7]

    Medicare Advantage is different

    Medicare Advantage (Part C) plans are run by private insurers. Some offer extra benefits that Original Medicare doesn’t cover, like vision. Medicare.gov’s advice is to contact the plan.[1] A plan’s vision benefit may include contact lenses, and may have its own medically necessary contact lens rules, networks, and prior authorization.

    If a provider expects Medicare not to pay

    With Original Medicare, a provider or supplier may give you an Advance Beneficiary Notice of Non-coverage (ABN) listing what they expect Medicare won’t cover, an estimated cost, and why. You choose an option on the form. If you ask for the item and for a claim to be submitted, you pay if Medicare denies it, but you can appeal. If you ask that no claim be submitted, you can’t appeal.[6]

    What to ask

    The practice:

    1. Are you enrolled with Medicare as a supplier for contact lenses?
    2. Which parts of my care do you bill to Medicare, and which are self-pay?
    3. Have you had claims paid for scleral lenses used for ocular surface disease?
    4. Will you give me an ABN, and what does it estimate?

    Your Medicare Advantage plan (if you have one):

    1. Does my plan have a vision benefit that covers contact lenses? A medically necessary contact lens benefit?
    2. Is my fitter in network?
    3. Is prior authorization required?

    Medicare rules and plan benefits change. Check Medicare.gov or call your plan for the current rules.

    Common questions

    Does Medicare cover scleral lenses for keratoconus?

    Original Medicare's eyeglass exclusion generally applies to lenses that correct vision, and keratoconus isn't one of the listed exceptions. Some Medicare Advantage plans include vision benefits that may help. Ask your plan and your fitter, who may know how Medicare has handled similar claims.

    Will Medicare pay for the eye exams even if it won't pay for the lenses?

    Medicare doesn't cover routine eye exams or refractions for glasses or contact lenses. Whether other parts of a fitting visit can be billed to Medicare depends on what was done and why. Ask the practice what they bill to Medicare and what they treat as self-pay.

    If I get contact lenses after cataract surgery, will Medicare replace them later?

    Medicare's coverage manual says that replacing the one pair of conventional glasses or contact lenses furnished after cataract surgery with a lens implant is not covered. Coverage is tied to each surgery, not to later replacements.

    What is an ABN and should I sign it?

    An Advance Beneficiary Notice tells you a provider expects Medicare not to pay for something and estimates the cost. Signing and choosing the option to have a claim submitted means you'll pay if Medicare denies it, but keeps your right to appeal. Read the options carefully before choosing.

    Does Medicaid cover scleral lenses?

    It varies by state. For adults, eyeglasses and other aids to vision are an optional Medicaid benefit, so each state decides whether to cover them and on what terms. For people under 21, the EPSDT benefit requires states to cover medically necessary treatment for vision conditions, even services the state plan doesn't list. Ask your state Medicaid agency or Medicaid health plan, and ask fitters whether they accept Medicaid.

    Medical insurance or vision insurance: which one pays for scleral lenses?

    Often it's split. Your medical plan may cover the exams and the fitting for an eye disease like keratoconus, while the lenses themselves are excluded and left to a vision plan, if you have one. Many vision plans have a separate, richer benefit for medically necessary contact lenses. Severe ocular surface disease is sometimes treated differently. Call both plans and ask the questions below.

    Paying for scleral lenses with an HSA or FSA, and other options

    Usually yes. IRS Publication 502 says you can include contact lenses needed for medical reasons as a medical expense, along with the supplies needed to use them, such as saline. That generally makes them eligible for HSA and FSA funds. Keep itemized receipts, check your account administrator's documentation rules, and be careful with deferred-interest medical credit cards.

    How to appeal a denied scleral lens claim

    Start by finding out exactly why the claim or prior authorization was denied. For most private health plans you can then file an internal appeal within 180 days of the denial notice, with a letter from your fitter and the records that answer the reason given. If the plan still says no, you can usually ask for an independent external review. Medicare and some other plan types have their own processes, so check your denial letter.
