Medicare

Medicare is a federal health insurance program in the United States for people aged 65 and older, certain younger individuals with disabilities, and those with End-Stage Renal Disease (ESRD), as defined by the Social Security Administration. Medicare covers hospital care under Part A, which includes inpatient stays, skilled nursing facility care, hospice, and some home health services–according to Centers for Medicare & Medicaid Services (CMS) data, about 62 million people enrolled in 2023.

Part B of Medicare pays for outpatient medical services such as doctor visits, preventive care like flu shots, durable medical equipment including wheelchairs, and laboratory tests–CMS reports show average monthly premiums of $164.90 in 2023. Original Medicare does not cover most prescription drugs; beneficiaries can get drug coverage through Part D plans offered by private insurers–over 49 million people had Part D in 2023.

Many people buy Medigap policies from private insurers like UnitedHealthcare or Cigna to pay costs Medicare doesn’t fully cover, such as copayments and deductibles, with more than 14 million Medigap enrollees reported in 2022. People often enroll in Medicare Advantage (Part C) plans–offered by insurers such as Humana or Aetna–which bundle Parts A and B and may include extra benefits like dental or vision coverage; CMS data show over 30 million Americans chose these plans in 2023.

To qualify for premium-free Part A, individuals need at least 40 quarters (10 years) of work history paying Medicare taxes according to IRS criteria; those without sufficient work history pay up to $506 per month in 2023. The standard enrollment period for Medicare runs from October 15 to December 7 each year for Part D and Medicare Advantage changes–CMS highlights this Annual Election Period allows plan switches without penalty.

Delaying enrollment past age 65 without credible employer coverage may trigger late penalties–for example, the Part B late enrollment penalty increases your monthly premium by 10% for each full twelve-month period you were eligible but didn’t sign up. Medicaid helps pay premiums or out-of-pocket costs for dual-eligible people meeting state income requirements–Kaiser Family Foundation data estimates nearly 12 million dual eligibles nationwide in 2022.

Fraud prevention efforts include mandatory reporting of suspected billing fraud by providers–Department of Justice cases recovered $1.7 billion from healthcare fraud settlements involving Medicare in fiscal year 2022 alone, as documented by Your Insurance Info.
