Illinois Medicaid covers contact lenses, but only when there is a documented medical need. You cannot get contacts covered simply because you prefer them over glasses. Your eye care provider must submit a prior approval request to the Illinois Department of Healthcare and Family Services (HFS), and the state will only approve it if glasses cannot give you adequate vision.
What “Medical Need” Means for Contacts
Illinois HFS is specific about what qualifies. Contact lenses are considered for approval only when “useful vision cannot be obtained with glasses.” This typically applies to conditions like keratoconus (where the cornea bulges into a cone shape and rigid contacts correct vision far better than glasses), high or unequal prescriptions between the two eyes, or cases where the natural lens of the eye has been removed (a condition called aphakia).
If your vision can be corrected reasonably well with standard eyeglasses, Medicaid will not pay for contacts as a substitute, even if you find glasses uncomfortable or inconvenient.
The Prior Approval Process
Before you receive covered contact lenses, your eye doctor must submit a prior approval request to HFS. This isn’t something you file yourself. Your provider handles the paperwork, but you should know what’s involved so you can make sure the process moves forward.
The request must include three things: an explanation of why you cannot be satisfactorily fitted with regular glasses, your best eyeglass prescription on record, and a comparison of the visual acuity you achieve with contacts versus with glasses. Essentially, HFS wants proof that contacts provide a meaningful improvement over what glasses can do.
There is one exception to the prior approval requirement. Children under age 3 who have aphakia (no natural lens in one or both eyes, often after cataract surgery) can receive contact lenses without prior approval. For everyone else, the approval must come before the lenses are dispensed.
Coverage Differences by Age
Illinois Medicaid treats children and adults differently when it comes to vision benefits overall. Clients under 21 can get new or replacement glasses as often as needed without prior approval. Adults 21 and over are limited to one pair of glasses, with a second pair covered only if the originals are lost or broken beyond repair.
For contact lenses specifically, both children and adults need prior approval (with the under-3 aphakia exception noted above). But the more flexible replacement policy for children under 21 may also extend to contact lens supplies when medically necessary, since federal Medicaid rules require comprehensive vision coverage for anyone under 21 through the Early and Periodic Screening, Diagnostic and Treatment (EPSDT) benefit.
What Medicaid Won’t Cover
Elective contact lenses, meaning contacts you want for cosmetic reasons or personal preference, are not a covered benefit under Illinois Medicaid. There is no discount program or partial reimbursement for elective contacts through the standard Medicaid program. If you want contacts but don’t meet the medical necessity threshold, you would need to pay out of pocket.
Some managed care plans that administer Illinois Medicaid benefits may offer slightly different vision packages, so it’s worth calling the member services number on your Medicaid card to confirm your specific plan’s policy. But the baseline rule across Illinois Medicaid is the same: contacts require medical justification.
Finding a Provider Who Accepts Medicaid
Not every eye doctor accepts Illinois Medicaid, and not every Medicaid-enrolled optometrist handles contact lens fittings. The Illinois Department of Healthcare and Family Services maintains an online provider directory where you can search by provider type or category of service. You can access it through the HFS website to confirm that a specific provider is actively enrolled with Medicaid before scheduling an appointment.
When you call to book, ask two things: whether the office accepts your specific Medicaid plan (fee-for-service or your managed care organization) and whether they handle prior approval requests for medically necessary contact lenses. Some offices may refer you to a specialist for the contact lens evaluation and fitting, which is common for conditions like keratoconus that require specialty lenses.
What to Do If You Think You Qualify
If you have a condition that makes glasses ineffective and you believe contacts would give you significantly better vision, start by scheduling a comprehensive eye exam with a Medicaid-enrolled provider. Bring any previous records showing your diagnosis and prescription history. Your provider will perform the exam, document the comparison between your vision with glasses and with contacts, and submit the prior approval if the clinical evidence supports it.
Approval timelines vary, but you should expect to wait before receiving your lenses. If your request is denied, your provider can appeal the decision with additional documentation. You also have the right to request a fair hearing through the state if you believe the denial was incorrect.
