    Insurance and cost

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

    Tax-advantaged accounts are often the most useful tool for the part of the cost insurance doesn't pay. Here is what the IRS says about contact lenses, how HSAs and FSAs differ, what to know before using financing, and where to turn if a claim was denied.

    The short answer

    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.

    Key points

    • IRS Publication 502 covers contact lenses needed for medical reasons and their supplies.
    • HSA money rolls over; FSA money is generally use-it-or-lose-it, with limited exceptions.
    • A health FSA's full yearly election is generally available from the start of the plan year.
    • Deferred-interest medical credit cards can charge interest back to the start if not paid off in time.
    • Ask about payment plans and financial assistance before agreeing to financing.

    What the IRS says about contact lenses

    IRS Publication 502 lists what counts as a medical expense. Under “Contact Lenses,” it says you can include amounts you pay for contact lenses needed for medical reasons, and the cost of equipment and materials required for using them, such as saline solution and enzyme cleaner.[1]

    For HSAs, “qualified medical expenses” are defined using the tax code’s definition of medical care,[2] and HealthCare.gov points to Publication 502 for the list of qualifying expenses.[3]

    In practice, that means scleral lenses prescribed for a condition like keratoconus or severe ocular surface disease, the fitting, and supplies like preservative-free saline are generally eligible. Your account administrator makes the call on individual claims and may ask for documentation.

    HSA or FSA: how they differ

    Health Savings Account (HSA). You can only contribute if you have an HSA-eligible health plan, sometimes called a high-deductible health plan.[3] Distributions used for qualified medical expenses aren’t taxed.[2] The money stays in your account from year to year: you don’t have to make withdrawals each year.[2] Expenses from before you opened the HSA don’t qualify.[2]

    Health Flexible Spending Arrangement (FSA). Offered through an employer, and you choose how much to put in, up to a limit your employer sets.[4] Two rules matter for scleral lenses:

    • Your full election is available early. You must be able to receive the full amount you elected for the year at any time during the coverage period, regardless of how much you’ve contributed so far.[2] That can help with a large fitting cost early in the plan year.
    • Use it or lose it. FSAs are generally use-it-or-lose-it, though a plan can offer either a grace period of up to 2 1/2 months or a limited carryover into the next year.[2] Ask your employer which, if either, applies.

    Contribution limits and carryover amounts are set each year, so check the current figures with your employer or the IRS.

    Financing and payment plans

    If you can’t pay all at once, practices may offer options:

    • An in-house payment plan from the practice itself.
    • A medical credit card or a third-party payment plan.

    The Consumer Financial Protection Bureau advises asking about financial assistance and what your insurance covers before agreeing to a payment plan or medical credit card.[5]

    It also warns that medical credit cards often defer interest for a promotional period. If you pay late or still have a balance when that period ends, you may owe significant interest and fees, and it can affect your credit.[5] Some installment plans are interest-free; others use deferred interest the same way.[5]

    Before you sign, ask:

    1. Is there interest, and is it deferred? What happens if I don’t pay it all off by the end of the promotional period?
    2. What’s the monthly payment, and what’s the total I’ll pay?
    3. Can I set up a payment plan directly with the practice instead?

    If you’re paying without insurance, you can also ask the practice for a written Good Faith Estimate of the total expected charges before you schedule.[6]

    If insurance said no

    A denied claim isn’t always final. Check the explanation of benefits for the reason, ask your fitter whether more documentation would help, and see the guide to appealing a denied claim.

    What to ask your HSA or FSA administrator

    1. Are prescribed contact lenses, the fitting, and lens care supplies eligible?
    2. What documentation do you need: an itemized receipt, a prescription, a letter?
    3. Can I pay the practice directly with the account card, or do I submit for reimbursement?
    4. For an FSA: does my plan have a grace period or a carryover, and what’s the deadline to submit claims?

    Common questions

    Do I need a letter of medical necessity to use my HSA or FSA for scleral lenses?

    It depends on your account administrator. Some ask for documentation for items that can be bought for medical or non-medical reasons. Your itemized receipt, showing the diagnosis or describing the lenses as medically prescribed, often helps. Ask the administrator what they need.

    Can I use HSA or FSA money for saline and cleaning solutions?

    IRS Publication 502 lists equipment and materials needed for using contact lenses, such as saline solution and enzyme cleaner, as medical expenses. Keep the receipts.

    Can I use my HSA for lenses I bought before I opened the account?

    No. IRS Publication 969 says expenses incurred before you establish your HSA aren't qualified medical expenses for HSA purposes.

    Can I deduct scleral lenses on my taxes?

    Medical expenses can be an itemized deduction, but only the part of your total medical and dental expenses above a threshold based on your adjusted gross income, and not expenses paid with tax-free HSA money or reimbursed by an FSA. IRS Publication 502 explains the current rule. A tax professional can tell you whether itemizing makes sense for you.

    How much do scleral lenses cost?

    It varies widely, and very little reliable price data is published. The bill has two main parts: the professional fitting (exams, measurements, follow-up visits) and the lenses themselves, and both grow with the number of visits and remakes your eyes need. One published US estimate put the lenses at several hundred dollars per eye and the initial fitting at several hundred more, at a single academic health system. Ask the practice for a written estimate that spells out what is and isn't included.

    Out-of-network claims and superbills for scleral lenses

    A superbill is an itemized statement from the practice with the codes, diagnoses, dates, and provider details your plan needs to process a claim. If your plan has out-of-network benefits, you submit it and the plan reimburses part of the cost based on its own allowed amount, after any deductible and coinsurance. Call your plan first to find out whether you have out-of-network benefits and how much they pay for the codes on your estimate.

    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.

    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.
