One of the biggest surprises for people turning 65 and enrolling in Medicare is discovering what it does not cover. Dental cleanings, eyeglasses, and hearing aids are three of the most common health expenses for older adults, yet Original Medicare provides little to no coverage for any of them. This guide explains exactly what Medicare covers, what it does not, and what options California beneficiaries have to fill these gaps in 2026.
What Is "Original Medicare" and Why Does It Have These Gaps?
Original Medicare refers to Medicare Part A (hospital insurance) and Medicare Part B (medical insurance). When Medicare was created in 1965, dental, vision, and hearing care were considered routine and relatively inexpensive, so they were excluded from the program. Congress has debated expanding these benefits for decades, but as of 2026, Original Medicare still does not cover them as routine benefits.
This gap affects millions of California seniors. Untreated hearing loss is linked to cognitive decline and social isolation. Poor dental health is associated with heart disease and diabetes complications. Vision loss is a leading cause of falls. These are not minor conveniences. They are health priorities.
Medicare and Dental Coverage in California
What Original Medicare Covers (and Does Not)
Original Medicare Part A will pay for dental services only when they are directly tied to a covered inpatient procedure. For example, if you are admitted to a hospital for jaw reconstruction after an accident, Part A may cover the medically necessary dental component. This is rare. Routine care, including annual cleanings, fillings, root canals, crowns, bridges, and dentures, is not covered at all.
Part B covers an oral examination before a kidney transplant or heart valve surgery, but only in that specific context. It does not cover the exam if you visit a dentist on your own.
How to Get Dental Coverage on Medicare in California
You have three main options. First, choose a Medicare Advantage plan that includes dental benefits. Many plans sold in California counties offer preventive dental (cleanings and X-rays) at no additional cost, and some include a dollar allowance for comprehensive dental work (fillings, crowns, extractions) ranging from $500 to $3,000 per year. Second, purchase a standalone dental insurance plan separate from Medicare. These are available through private insurers and cost approximately $20 to $50 per month for basic coverage. Third, if your income is low enough to qualify for both Medicare and Medi-Cal (California's Medicaid program), Medi-Cal covers comprehensive dental care for dual-eligible beneficiaries, including exams, cleanings, fillings, and dentures.
Medicare and Vision Coverage in California
What Original Medicare Covers
Medicare Part B does cover specific medically necessary eye care. This includes annual dilated eye exams for people with diabetes, glaucoma screenings once every 12 months for people at high risk (including anyone with a family history of glaucoma, African Americans age 50 or older, and Hispanic Americans age 65 or older), and treatment for eye diseases and conditions such as macular degeneration, cataracts requiring surgery, and retinal detachments.
What Part B does not cover is equally important to understand: routine eye exams for glasses or contact lenses, prescription eyeglasses, contact lenses, and most corrective lenses. The one exception is that Part B covers one pair of eyeglasses or contact lenses after cataract surgery that implants a standard intraocular lens.
How to Get Vision Coverage on Medicare in California
Many Medicare Advantage plans in California include routine vision benefits, typically a covered annual eye exam and an annual allowance of $100 to $300 toward eyeglass frames, lenses, or contact lenses. If you want to keep Original Medicare with a Medigap supplement, you can purchase a standalone vision plan for roughly $10 to $20 per month. Dual-eligible Californians covered by both Medicare and Medi-Cal receive comprehensive vision care through Medi-Cal, including eye exams and eyeglasses.
Medicare and Hearing Coverage in California
What Original Medicare Covers
Medicare Part B covers diagnostic hearing and balance exams when your doctor orders them to determine whether you need medical treatment. These are billed by audiologists as diagnostic services, not routine hearing tests. The distinction matters: if you walk into an audiologist's office seeking a routine hearing test for a hearing aid fitting, Part B will not cover it. The exam must be medically ordered.
Original Medicare does not cover hearing aids or the routine exams associated with fitting them. Hearing aids can cost between $1,000 and $7,000 per pair, representing a major out-of-pocket expense for many seniors.
How to Get Hearing Coverage on Medicare in California
Medicare Advantage plans increasingly include hearing benefits. Many plans offer an annual allowance toward hearing aids, commonly ranging from $500 to $2,500. Some plans also cover routine hearing exams. Coverage varies significantly by plan and county, so comparing options before the enrollment deadline is critical.
Some California seniors choose to purchase hearing aids through direct-to-consumer companies, which can reduce costs significantly compared to audiologist channels. OTC hearing aids, available since 2022, provide another lower-cost option for people with mild to moderate hearing loss.

Should You Switch to Medicare Advantage for These Benefits?
Medicare Advantage can be an excellent choice if dental, vision, and hearing benefits are important to you, especially if you qualify for a $0-premium plan in your California county. Before switching, consider a few things.
Medicare Advantage plans use networks. You will need to use in-network providers for most care, unlike Original Medicare which works with any provider nationwide who accepts Medicare. The dental and vision benefit limits may not cover major procedures. A plan that offers $1,000 in dental benefits sounds helpful until you need a crown and an implant in the same year.
If you already have a Medigap supplement and want to keep it, the better path may be to add a standalone dental and vision plan rather than switching your entire coverage. Speak with a licensed California Medicare agent to compare the total cost picture before making any change.
