Question

Does insurance cover a spare pair of scleral lenses?

A lost or broken scleral lens can leave you unable to see well for weeks. Many wearers want a backup pair, and many find their plan won't pay for one. Here's how coverage for spares and replacements tends to work, and what to ask.

The short answer

Often not, but it depends entirely on your plan. Many plans cover one pair per benefit period and replace lenses only for a medical reason, such as a change in your eye condition, not for a lost or broken lens or a spare. Some plans make exceptions or handle requests case by case. Ask your plan in writing what it covers for replacements and backups, and ask your fitter about keeping your previous pair as a spare.

Key points

  • Many plans pay for one pair, and treat a spare as not medically necessary.
  • Lost or broken lenses are often excluded, but some plans review them case by case.
  • Published policies differ: check your own plan's written rules.
  • Ask your fitter whether your previous pair can serve as a backup.
  • HSA and FSA funds can usually be used for medically needed contact lenses.

Why wearers want a spare

Scleral lenses are custom made, so a replacement can take time to arrive. Lenses do get lost, chipped, and broken. In one study of 157 keratoconus eyes that had worn scleral lenses successfully for at least a year, broken lenses were recorded in 26.1% of eyes.[4] For someone who sees poorly without lenses, or whose eye surface depends on the lens, even a short gap can be hard.

That’s why many wearers, and many fitters, like the idea of a backup. Insurance is a different matter.

How plans usually treat spares and replacements

Plans write their own rules, and those rules change. In general:

  • One pair per benefit period is common. Wearers often describe vision benefits that cover lenses once a year or less often.
  • A spare pair is often seen as a convenience. Plans that cover medically necessary lenses usually cover what’s needed to treat your condition, which they may define as one pair.
  • Replacements are usually tied to a medical reason. A change in your eye condition is more likely to be covered than a lost or broken lens.
  • Some plans review losses case by case.

Two published policies show the range:

  • Aetna’s medical clinical policy says replacement lenses are considered medically necessary under medical plans when they’re needed because of a change in the patient’s physical condition, not counting refractive changes, and that charges to replace lenses that are lost, damaged, or needed only because of a refractive change aren’t covered under medical plans. It also notes that additional coverage may come through a member’s vision plan.[1]
  • The Veterans Health Administration’s directive says replacement contact lenses aren’t normally provided unless medically necessary, and that a second lens or pair may be provided when losing or destroying a lens creates a severe hardship or a compelling medical need, on the recommendation and approval of a VA eye care provider.[2]

Your plan may be quite different from either. See our pages on Aetna, the VA, TRICARE, Kaiser Permanente, Cigna, Blue Cross Blue Shield, UnitedHealthcare, and Medicare for what each publishes.

Medical plan or vision plan?

Scleral lenses can be covered by a medical plan, a vision plan, or sometimes both, and each has its own replacement rules. A medical plan may cover your fitting but not replacements; a vision plan may cover a new pair once a year whatever happened to the old one. See medical vs. vision insurance and what counts as medically necessary contact lenses.

Other ways wearers get a backup

  • Keep your previous pair. When you get new lenses, many wearers keep the old ones as an emergency spare, with their fitter’s agreement. Ask your fitter to check the old lenses and tell you how to store them. An older lens may not fit or see as well as your current one.
  • Use the warranty. New lenses are often under a practice or lab warranty for a period. Ask what it covers before you need it.
  • Time a new pair with your benefit. Some wearers whose plan covers a pair each year order a new pair and keep the previous year’s as the backup.
  • Pay with HSA or FSA funds. IRS Publication 502 says you can include amounts you pay for contact lenses needed for medical reasons, and the equipment and materials for using them, such as saline solution, in medical expenses.[3] See HSA, FSA, and paying for sclerals.
  • Check other insurance. A few wearers have had a lost lens covered under a homeowners or renters policy. It depends on your policy.

What to ask your plan

Get the answers in writing if you can:

  1. How often do you cover scleral lenses, and is that per lens or per pair?
  2. Do you cover a spare or backup pair? Under what circumstances?
  3. Do you cover replacement of a lost or broken lens?
  4. Do you cover replacement if my eye condition or prescription changes?
  5. Does a replacement need prior authorization or a new letter of medical necessity?
  6. If my medical plan says no, could my vision plan cover it, or the other way round?

Our pages on prior authorization, letters of medical necessity, and appealing a denied claim can help if the answer is no. If your fitter is out of network, see out-of-network claims and superbills.

What wearers say

Most wearers who ask about spares report that their plan said no, or covered one pair per year. Many keep their previous lenses as a backup and say it saved them when a lens broke or went missing. Some had a spare approved after their fitter documented that they couldn’t see or function without the lenses. Others paid for a backup themselves, often with HSA or FSA funds, and describe it as peace of mind.

What to ask your fitter

  • Can my old lenses be my backup, and how should I store them?
  • What does my warranty cover, and for how long?
  • Would you document why I need a backup for my insurer?
  • If a lens breaks, how fast can you replace it?

Common questions

My lens broke. Will my plan replace it?

Check two things first: whether the practice or lab warranty still covers the lens, since new lenses are often under warranty for a period, and what your plan says about lost or damaged lenses. Some plans exclude them; some review them case by case. Call your fitter's office first, as they know the warranty terms.

Can my fitter write a letter so I can get a backup pair?

Your fitter can document why a backup matters for you, for example if you have no useful vision without the lens. Whether that changes the decision depends on your plan. A few published policies allow a second lens when losing one would cause severe hardship or a compelling medical need.

Can I keep my old lenses as a spare?

Many wearers do, with their fitter's agreement. An older lens may not fit or see as well as your current one, and lenses can change in storage, so ask your fitter to check it and tell you how to store it.

Would homeowners or renters insurance cover a lost lens?

Some wearers have tried this. Whether it applies depends on your policy and its deductible. Read the policy or ask your insurer.

Can I use my HSA or FSA for a spare pair?

Usually, if the lenses are needed for medical reasons. IRS Publication 502 lists contact lenses needed for medical reasons, and supplies such as saline, as medical expenses. Check your account's rules and keep your receipts.

What counts as medically necessary contact lenses?

It means lenses needed to treat or see with a qualifying eye condition, where glasses don't do the job. Plans that publish criteria commonly list keratoconus and other irregular corneas, very high prescriptions, a large difference between the eyes, missing natural lens or iris, and severe ocular surface disease. Each plan sets its own conditions, measurements, and paperwork, and meeting the criteria doesn't guarantee approval. Ask your plan for its written criteria.

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.

The letter of medical necessity for scleral lenses

It's a signed letter from your eye doctor explaining your diagnosis, the test results that support it, what you've already tried, and why scleral lenses are needed. Plans that publish their requirements ask for the specific indication, supporting history, exam and test results, and the lens prescription. Your fitter writes and signs it; you can help by getting your plan's written criteria and your old records to the office.

My scleral lens cracked or chipped. Can I still wear it?

No. Don't put a cracked or chipped scleral lens in your eye, even for a few hours. A chip or crack weakens the lens and can scratch your eye or break apart while it's in. Keep the pieces in your case, call your fitter to order a replacement and ask about the warranty, and wear your glasses or a backup lens your fitter has approved until the new one arrives.
