Summary: The Fine Print They Hand You at 65

The Medicare card arrives a few months before your 65th birthday. You have paid into the system for decades. It will be there when you need it. It just will not be there for everything you need, and nobody explains the difference clearly until you are standing in a dentist’s office, a hearing clinic, or a rehab facility learning what “not covered” actually means when the bill is yours.

Medicare covers hospitalizations, physician visits, preventive screenings, and prescription drugs. For what it covers, it works. The problem is what it does not cover: the services that aging bodies need most routinely, most expensively, and most urgently. Dental care, hearing aids, routine vision, and long-term custodial care are excluded, not as oversights but as structural features of a program designed in 1965, when the average American died at 70.

The dental gap alone is severe. Medicare covers no routine dental services. Fifty-six percent of Americans 65 and older have no dental benefits of any kind. A crown runs roughly $1,500. A full set of dentures can exceed $5,000. Untreated dental disease leads to infections, malnutrition, and documented cardiovascular risk. Hearing aids cost $2,000 to $6,000 per pair, and a Lancet Commission report identified untreated hearing loss as the single largest modifiable risk factor for dementia. Routine vision exams and glasses are excluded too: a senior wearing an outdated prescription faces increased fall risk and reduced independence. Multiple bills to add dental, vision, and hearing to Medicare have been introduced in Congress. None have passed.

The long-term care exclusion can destroy a family’s finances entirely. Medicare does not cover the sustained daily help that most people with advanced chronic conditions or dementia eventually require. A home health aide costs roughly $6,300 a month. A semi-private nursing home room exceeds $8,700. Roughly 70% of people turning 65 will need some form of long-term care, and Medicare pays for almost none of it.

The supplemental insurance landscape offers partial answers. Medigap plans cover cost-sharing for services Medicare already covers but add nothing Medicare leaves out. Medicare Advantage plans often include limited dental, vision, and hearing benefits, but they restrict provider networks and require prior authorization. Those trade-offs may be sharpening: CMS proposed effectively flat funding for Advantage plans in 2027, and the supplemental benefits that make Advantage attractive may be the first thing insurers trim.

Technology can make covered care smarter through remote monitoring, telehealth, and AI-assisted diagnostics. CMS launched a new payment model for tech-enabled chronic disease management in traditional Medicare. But a remote glucose monitor does not clean your teeth, fit your hearing aids, or help you get dressed in the morning. The gaps in Medicare are benefit gaps, written into the law, that require legislative action to fix. Technology cannot add what the law leaves out.

The most important thing you can do is understand exactly what your coverage includes and what it does not. Start with a free SHIP counseling session. Review your coverage every year during Open Enrollment. Budget explicitly for what Medicare will not pay. The card in your wallet promises a great deal. Just not everything you will need.
