Does Medicare cover all services?

No, Original Medicare (Parts A & B) does not cover everything; it has significant gaps, especially for dental, vision, hearing, prescription drugs, and long-term care, and doesn't pay 100% of covered costs, leaving beneficiaries with deductibles, coinsurance, and copays. To fill these gaps, people often use Medicare Advantage Plans (Part C), Medicare Supplement (Medigap) plans, or separate Part D drug plans.


What are some things that Medicare doesn't cover?

Original Medicare (Parts A & B) generally doesn't cover routine dental, vision (glasses, exams), hearing aids, long-term custodial care, most cosmetic surgery, or prescription drugs (that's Part D). It also excludes services like acupuncture, most chiropractic care, private-duty nursing, and personal comfort items in hospitals (like TVs). Medicare Advantage (Part C) plans often fill these gaps with extra benefits like vision, dental, and hearing coverage, but it depends on the specific plan.

Does Medicare pay 100% of anything?

No, Original Medicare (Part A & B) does not cover 100% of costs; it typically pays about 80% after deductibles, leaving you with 20% coinsurance for many services, plus gaps like dental, vision, and most drugs, requiring you to pay out-of-pocket or get supplemental coverage like Medicare Advantage (Part C) or Medigap. Some preventive services are covered at 100%, but most care has cost-sharing. 

Is Medicare alone enough?

No, Original Medicare (Parts A & B) typically isn't enough because it doesn't cover prescription drugs (needs Part D), has no out-of-pocket spending limit, and misses routine dental, vision, and hearing care, leading most beneficiaries to add Medigap (Supplement) or choose Medicare Advantage (Part C) for comprehensive coverage. Deciding what's "enough" depends on your health, budget, and comfort with risk, as Original Medicare leaves significant costs to you.

What are the biggest mistakes people make with Medicare?

The biggest Medicare mistakes involve missing enrollment deadlines, failing to review plans annually, underestimating total costs (premiums, deductibles, copays), not enrolling in a Part D drug plan with Original Medicare, and assuming one-size-fits-all coverage or that Medicare covers everything like long-term care. People often delay enrollment, get locked into old plans without checking for better options, or overlook financial assistance programs, leading to higher out-of-pocket expenses and penalties. 

Is it better to go on Medicare or stay on private insurance?
