Medi-Cal does cover cataract surgery when it is medically necessary, and that includes the lens implant, facility, and anesthesia. The surgeon’s office has to get prior authorization through a Treatment Authorization Request (TAR) and show that the cataract is actually interfering with your daily life, not just that it exists.1Medi-Cal. Eye Surgery Manual
What Counts as Medically Necessary
A cataract diagnosis alone is not enough. The TAR has to document that the cataract is causing real problems and that glasses or other non-surgical options cannot fix them.1Medi-Cal. Eye Surgery Manual
If your best-corrected visual acuity in the affected eye is 20/50 or worse, your provider needs to note symptoms like blurred vision, distortion, or glare, along with evidence that activities such as reading, writing, or driving have become harder.1Medi-Cal. Eye Surgery Manual
You can still qualify with better vision (20/40 or above), but the documentation bar is higher. The provider must show one of three things: fluctuating vision from glare or dim light 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 the diagnosis or treatment of something at the back of the eye, like diabetic retinopathy.1Medi-Cal. Eye Surgery Manual
Medi-Cal will deny the surgery if you decline the procedure, if your daily life is not meaningfully compromised, if glasses or 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 Prior Authorization Works
Every cataract surgery under Medi-Cal needs a TAR, which the surgeon’s office submits for you. It has to include your symptoms, best-corrected visual acuity measurements, a qualifying diagnosis code, and documentation of functional impairment.1Medi-Cal. Eye Surgery Manual
Timing depends on your health plan. One Medi-Cal managed care plan, CenCal Health, decides routine requests within five working days when the documentation is complete, up to 14 days when more information is needed, and three working days for expedited requests.2CenCal Health. Treatment Authorization Your own plan’s timeline may differ, so ask the surgeon’s office when they expect a decision.
If you need both eyes done, Medi-Cal expects a three- to four-week recovery between procedures. A single TAR can cover both eyes within a six-month window, but only if each eye independently meets the criteria. If only one qualifies now, the TAR is approved for the worse eye, and a new request has to go in later for the second eye once it meets the threshold.1Medi-Cal. Eye Surgery Manual
What the Covered Surgery Includes
An approved cataract surgery under Medi-Cal covers both the removal of the cataract and the intraocular lens implant. The billing codes (CPT 66982 through 66984, 66989, and 66991) bundle the lens with the extraction as a single reimbursable service.1Medi-Cal. Eye Surgery Manual
Medi-Cal’s surgical manual does not spell out a distinction between standard monofocal lenses and premium options such as multifocal, accommodating, or toric lenses. In other government and private coverage, patients who choose a presbyopia- or astigmatism-correcting premium lens pay the price difference themselves, because those lenses are treated as upgrades rather than medically necessary items.3CMS. PC-AC-IOL Laser Guidance4Aetna. Clinical Policy Bulletin: Cataract Surgery If you want a premium lens, confirm the cost arrangement with your Medi-Cal managed care plan before the surgery is scheduled.
Laser-assisted cataract surgery is similarly unaddressed in the Medi-Cal surgical manual. Check with your plan if that is the technique you want.
What You Will Pay
Most Medi-Cal beneficiaries pay nothing out of pocket for covered services, surgery included. The exception is beneficiaries whose income puts them into Medi-Cal with a “share of cost,” which works like a monthly deductible: you cover medical expenses up to that amount in a given month before Medi-Cal pays the rest for that month.5California Advocates for Nursing Home Reform. Understanding the Share of Cost for Medi-Cal
As of April 2025, the single-beneficiary 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 In practice, the cost of cataract surgery in the month it happens will usually meet or exceed that share, and Medi-Cal picks up the balance.
If You Have Both Medicare and Medi-Cal
For dual-eligible Californians, Medicare pays first for the surgeon and facility, and Medi-Cal acts as the secondary payer, covering Medicare’s deductible and the standard 20 percent coinsurance.6California Health Care Foundation.

Finding a Surgeon Who Takes Medi-Cal
You generally do not need a referral to see an in-network vision provider, but you must use one who accepts your Medi-Cal managed care plan or fee-for-service Medi-Cal. The fastest way to get a list is to call your managed care plan. Plans like LA Care, Molina, and Kaiser partner with vision networks that include VSP, Envolve Vision, and March Vision Care.8DHCS. Medi-Cal Vision Benefits
Finding a provider nearby can be harder than it should be. Optometry reimbursement rates have not changed in roughly 25 years, with California paying $47 for a new patient eye exam, described as the third lowest rate in the nation and less than half the national Medicaid average. About 10 percent of California optometrists have left the Medi-Cal program in the past two years, and 90 percent say their patients have trouble finding a Medi-Cal provider nearby.9California Optometric Association. Children Enrolled in Medi-Cal Still Can’t Access Basic Vision Care
Access on the surgical side runs into a related problem for dual-eligible patients. Because Medi-Cal rates are often lower than the Medicare-approved amount, the state’s secondary payment to a provider can be very small or even zero, and some providers decline dual-eligible patients for that reason.6California Health Care Foundation. Primer on Dual-Eligible People Enrolled in Medicare and Medi-Cal If the first few offices turn you away, keep calling. Your plan’s member services line can usually identify surgeons currently accepting new Medi-Cal patients.
