Medi-Cal does cover cataract surgery when a surgeon documents that the cataract is causing real problems in your daily life and the case is approved in advance through a Treatment Authorization Request (TAR). The covered service bundles the cataract removal, a standard intraocular lens implant, and the related facility and anesthesia charges. Approval is not automatic: having a cataract is not enough on its own.
When Medi-Cal Will Approve the Surgery
Medi-Cal’s eye surgery manual sets different thresholds depending on how bad your vision already is.
If your best-corrected visual acuity in the affected eye is 20/50 or worse, your surgeon must document symptoms such as blurred vision, visual distortion, or glare, along with evidence that everyday activities like reading, writing, or driving have become harder.1Medi-Cal. Eye Surgery Manual
If your corrected vision is still 20/40 or better, you can still qualify, but the bar is higher. The surgeon has to show one of the following: fluctuating vision from glare or dim lighting confirmed by brightness acuity testing; double or multiple images in one eye (monocular diplopia or polyopia); or a significant difference in vision between the two eyes.1Medi-Cal. Eye Surgery Manual
Surgery is also approved when the cataract itself is causing other eye disease, such as phacomorphic or phacolytic glaucoma, or when the clouded lens is blocking your doctor from diagnosing or treating something in the back of the eye, like diabetic retinopathy.1Medi-Cal. Eye Surgery Manual
Reasons Medi-Cal Will Deny
The request will be turned down if you decline the procedure, if your daily life is not meaningfully affected, if glasses or other visual aids still give you satisfactory vision, or if you are medically unfit for surgery in a way that means the operation would not improve your independence.1Medi-Cal. Eye Surgery Manual
How the TAR Process Works
Your surgeon’s office submits the TAR on your behalf. It has to include documentation of your symptoms, your best-corrected visual acuity readings, a qualifying diagnosis code, and evidence of functional impairment.1Medi-Cal. Eye Surgery Manual
Timing depends on your health plan. As one benchmark, the managed care plan CenCal Health says routine decisions come within five working days when the paperwork is complete, up to 14 days if more information is needed, and within three working days for expedited requests.2CenCal Health. Treatment Authorization
If you need both eyes done, Medi-Cal expects a three- to four-week recovery period between the two surgeries. A single TAR can cover both eyes for a six-month window, but only if each eye independently meets the criteria. If only one eye qualifies now, the TAR is approved for the worse eye, and a separate request goes in later once the second eye crosses the threshold.1Medi-Cal. Eye Surgery Manual
What the Covered Surgery Includes
The approved procedure covers both removing the cataract and inserting an intraocular lens. The billing codes involved (CPT 66982 through 66984, 66989, and 66991) bundle the lens implant with the cataract extraction as a single reimbursable service.1Medi-Cal. Eye Surgery Manual
Premium Lenses and Laser-Assisted Surgery
Medi-Cal’s surgical manual does not draw an explicit line between standard monofocal lenses and premium options like multifocal, accommodating, or toric lenses. The pattern across other government and private coverage is worth knowing. Under Medicare, patients who pick a premium presbyopia-correcting or astigmatism-correcting lens pay the difference between that lens and a conventional one out of pocket.3CMS. PC-AC-IOL Laser Guidance Major private insurers treat those same lenses as “deluxe” items that are not medically necessary.4Aetna. Clinical Policy Bulletin: Cataract Surgery If you are considering a premium lens, confirm coverage with your Medi-Cal managed care plan before surgery.
Laser-assisted cataract surgery sits in a similar gray zone. Medicare treats laser and conventional manual surgery as equivalent methods and covers them the same way.3CMS. PC-AC-IOL Laser Guidance The Medi-Cal manual doesn’t specifically address laser techniques, so check with your plan if that matters to you.
What You Will Pay
Most Medi-Cal beneficiaries pay nothing out of pocket for covered services, including surgery.
Some Medi-Cal enrollees have coverage with a “share of cost,” which works like a monthly deductible: you pay for medical services up to that amount each month before Medi-Cal starts paying for the rest of that month. As of April 2025, a single beneficiary’s maintenance-need level is $600 per month, and an individual with countable income above $1,801 (138 percent of the federal poverty level) may have a share of cost.5California Advocates for Nursing Home Reform. Understanding the Share of Cost for Medi-Cal For someone in that situation, the cost of cataract surgery in the month it happens will typically satisfy or exceed the share, and Medi-Cal covers the rest.
If You Have Both Medicare and Medi-Cal
Many older Californians who need cataract surgery are enrolled in both programs. For dual-eligible individuals, Medicare pays first for the surgical and physician services, and Medi-Cal picks up the cost-sharing that would otherwise be yours, including the Medicare deductible and the 20 percent coinsurance.6California Health Care Foundation. Primer on Dual-Eligible People Enrolled in Medicare and Medi-Cal
Federal and state law protect dual-eligible enrollees from out-of-pocket costs for Medicare-covered services, so you should owe nothing for the surgery. Balance billing is prohibited, and providers in dual special-needs plans are instructed not to collect copayments from these members.6California Health Care Foundation. Primer on Dual-Eligible People Enrolled in Medicare and Medi-Cal7Health Net California. Overview of Medicare Coordination of Benefits
There is a wrinkle on the provider side that can affect you indirectly. Medi-Cal rates are often lower than the Medicare-approved amount, so the state’s secondary payment to the surgeon can be very small or even zero. Some providers decline dual-eligible patients as a result, which can make it harder to find a surgeon who will take you.6California Health Care Foundation. Primer on Dual-Eligible People Enrolled in Medicare and Medi-Cal
Finding a Surgeon Who Takes Medi-Cal
You generally do not need a referral to see an in-network vision provider, but you have to use providers who accept your specific managed care plan or fee-for-service Medi-Cal. To find an ophthalmologist in-network, contact your plan directly. Plans such as LA Care, Molina, and Kaiser partner with vision networks including VSP, Envolve Vision, and March Vision Care.8DHCS. Medi-Cal Vision Benefits
Access has been a real problem. Reimbursement rates for optometrists have not moved in roughly 25 years, with California paying $47 for a new patient eye exam, described by the California Optometric Association as the third lowest rate in the country and less than half the national Medicaid average. Around 10 percent of California optometrists have left the Medi-Cal program in the past two years, and 90 percent said their patients have difficulty finding a Medi-Cal provider nearby.9California Optometric Association. Children Enrolled in Medi-Cal Still Can’t Access Basic Vision Care The 2024 state budget (SB 159) includes provisions to raise Medi-Cal reimbursement for optometry services to 87.5 percent of Medicare levels, with the increase set to take effect in 2026, contingent on the status of a specific ballot initiative.10California Optometric Association.

If your first call comes up empty, ask your managed care plan’s member services line for a current list of ophthalmologists who perform cataract surgery in-network, and be prepared to travel further than you might expect.
