Medicare's Coverage of Glasses After Cataract Surgery

Medicare Part B covers one pair of glasses or contact lenses after cataract surgery, but only if your eye surgeon implants an intraocular lens (IOL) during the procedure. The coverage includes the frames and lenses needed to correct your vision after the surgery. This is one of the few times Medicare pays for eyewear at all — routine glasses for distance or reading are not covered under standard Medicare.

The glasses must be ordered within a specific window: you can get them anytime after surgery, but Medicare will only pay if you obtain them within 12 months of the procedure. Your surgeon's office or the surgical facility will typically refer you to an optometrist or ophthalmologist who can write the prescription and order the frames and lenses through a supplier that accepts Medicare.

Medicare pays 80 percent of the approved amount for the glasses after you have met your Part B deductible for the year. You pay the remaining 20 percent coinsurance. If you have a Medigap or Medicare Advantage plan, your out-of-pocket cost may be lower depending on your plan's coverage rules.

Key Takeaways

  • Medicare Part B covers one pair of glasses or contact lenses after cataract surgery with an intraocular lens implant, paying 80 percent of the approved amount after your deductible.
  • You must obtain the glasses within 12 months of surgery, though you can wait any length of time within that window.
  • Your surgeon or surgical facility will refer you to an eye care provider who works with Medicare, so you do not need to find one yourself.
  • If you have a Medicare Advantage plan instead of Original Medicare, your coverage and costs may differ — check your plan documents or call your plan's customer service number.
  • Routine glasses for everyday vision correction outside of post-surgery care are not covered by Medicare, even after cataract surgery.

How the Referral and Ordering Process Works

After your cataract surgery, your surgeon or the surgical center will give you a prescription for glasses. They will also provide a referral to an optometrist or ophthalmologist who accepts Medicare and can dispense the covered glasses. You do not have to use the referred provider, but using one ensures the claim will be processed correctly and you will not be billed for amounts Medicare should cover.

When you visit the eye care provider, bring your Medicare card and the prescription from your surgeon. The provider will measure your eyes for the correct lens prescription and help you choose frames. They will then submit the claim to Medicare on your behalf. The entire process — from referral to receiving your glasses — typically takes two to four weeks, depending on how quickly the provider can order and fit the frames.

If you choose a provider who does not accept Medicare assignment, you may have to pay the full cost upfront and then file a claim yourself for reimbursement. This is more complicated and slower, so it is worth asking whether a provider accepts Medicare assignment before you schedule an appointment.

What Medicare Considers "Approved Amount" and What You Pay

Medicare sets an approved amount for post-cataract-surgery glasses based on the type of frames and lenses you choose. The approved amount varies by region and by the complexity of the lenses — for example, bifocals or progressive lenses may have a higher approved amount than single-vision lenses. Your eye care provider can tell you what the approved amount is before you order.

If you choose frames or lenses that cost more than the approved amount, you will pay the difference out of pocket in addition to your 20 percent coinsurance. For example, if the approved amount is $200 and you choose frames that cost $300, Medicare pays 80 percent of $200 ($160), you pay 20 percent of $200 ($40), and you also pay the $100 difference — for a total of $140 out of pocket.

To keep your costs down, ask your eye care provider which frames and lens options fall within the Medicare approved amount. Many providers have a selection of frames specifically chosen to stay within that limit.

Medicare Advantage Plans and Supplemental Coverage

If you have a Medicare Advantage plan (Part C) instead of Original Medicare with Part B, your coverage for post-cataract-surgery glasses may be different. Some Medicare Advantage plans cover the same one pair of glasses as Original Medicare does. Others may cover two pairs, or may have different cost-sharing rules. A few plans do not cover post-surgery glasses at all.

Check your Medicare Advantage plan's Summary of Benefits or call the plan's customer service number to learn what your plan covers for glasses after cataract surgery. The plan's website usually has this information, or you can find it by logging into your account online. If you are unsure whether your plan covers this benefit, ask before you have surgery so you can plan your out-of-pocket costs.

If you have a Medigap (supplemental insurance) plan in addition to Original Medicare, your plan may cover some or all of the 20 percent coinsurance you would otherwise pay. Review your Medigap plan documents or call your supplemental insurance company to confirm what they cover for eyewear after cataract surgery.

The 12-Month Window and When to Order Your Glasses

You have 12 months from the date of your cataract surgery to order your covered glasses. This means you can wait weeks or months after surgery if you want to — you do not have to order them when ready. However, once 12 months have passed, Medicare will no longer pay for the glasses, even if you had not yet ordered them.

Many people wait a few weeks after surgery before ordering glasses because your vision can continue to stabilize during that time. Your surgeon can advise you on when your vision is stable enough for an accurate glasses prescription. Some surgeons recommend waiting four to six weeks; others say two to three weeks is sufficient. Waiting too long, however, risks running past the 12-month important date.

If you have cataract surgery on both eyes at different times, you get a separate 12-month window for each eye. For example, if you have surgery on your left eye in January and your right eye in June, you have until January of the following year to order glasses for the left eye and until June of the following year for the right eye.

Contact Lenses as an Alternative to Glasses

Medicare covers contact lenses instead of glasses after cataract surgery, but only if you choose one or the other — not both. The coverage and cost-sharing are the same as for glasses: Medicare pays 80 percent of the approved amount after your deductible. Contact lenses are often more expensive than glasses, so your out-of-pocket cost may be higher.

If you want contact lenses, your eye care provider can fit you and order them through a Medicare-approved supplier. You will need to learn how to insert, remove, and care for the lenses, which takes practice. Some people find this difficult after cataract surgery, especially if they have arthritis or other conditions that affect hand dexterity. Discuss with your eye care provider whether contact lenses are practical for you before you commit to them.

What Happens If You Do Not Use Your Covered Glasses Benefit

If you do not order glasses within the 12-month window after cataract surgery, you lose the benefit. Medicare will not reimburse you for glasses you order after that important date, even if you had a valid reason for the delay. There is no way to extend the 12-month window or to use the benefit later.

If you have a second cataract surgery later — for example, on your other eye — you will receive a new 12-month window and a new covered glasses benefit. But the benefit from your first surgery cannot be carried forward or combined with the benefit from your second surgery.

Frequently Asked Questions

Can I get a second pair of glasses if I need them for reading and distance?

No. Medicare covers one pair of glasses total after cataract surgery, regardless of whether you need them for distance, reading, or both. If you need bifocals or progressive lenses to see at multiple distances, those count as one pair. If you want a second pair for backup or a different purpose, you will have to pay for it yourself.

What if my surgeon did not implant an intraocular lens?

Medicare does not cover glasses after cataract surgery without an IOL implant. If your surgeon removed the cataract but did not implant a lens, you would need thick, heavy glasses or contact lenses to see clearly, but Medicare will not pay for them. Discuss lens implant options with your surgeon before surgery if you are concerned about this.

Do I have to use the eye care provider my surgeon referred me to?

No, you can use any optometrist or ophthalmologist you choose. However, using a provider who accepts Medicare assignment makes the process simpler and ensures you will not be billed for amounts Medicare should cover. If you use a provider who does not accept assignment, you may pay more out of pocket and have to file a claim yourself.

Will my glasses prescription change after the first few weeks of surgery?

Yes, your vision can continue to improve and stabilize for several weeks after cataract surgery. Most surgeons recommend waiting at least two to four weeks before getting a final glasses prescription. Waiting longer gives your eye more time to heal, but waiting past 12 months means you lose Medicare coverage.

What if I have cataract surgery on both eyes at different times?

You get a separate 12-month window and a separate covered glasses benefit for each eye. If you have surgery on one eye in January and the other in July, you have until January of the next year to order glasses for the first eye and until July of the next year for the second eye. You can order glasses for each eye separately or wait and order both pairs together.
