Medicare
Medicare is a national health insurance program in the United States, begun in 1965 under the Social Security Act and administered by the Centers for Medicare & Medicaid Services (CMS), a division of the Department of Health and Human Services (HHS). This program primarily provides health insurance for Americans aged 65 and older, younger people with certain disabilities, and individuals with End-Stage Renal Disease (ESRD).
History
- 1965: President Lyndon B. Johnson signed the Medicare Bill into law, extending health coverage to older Americans as part of his Great Society initiatives. Medicare was originally split into two parts: Medicare Part A (hospital insurance) and Medicare Part B (medical insurance).
- 1972: The program was expanded to cover people under 65 with disabilities and those with ESRD.
- 1982: The introduction of Prospective Payment System (PPS) for hospital services, which changed the way hospitals were reimbursed.
- 1997: The Balanced Budget Act introduced Medicare+Choice, which later evolved into Medicare Advantage.
- 2003: The Medicare Prescription Drug, Improvement, and Modernization Act added a prescription drug benefit (Part D) and introduced Medicare Advantage plans.
- 2010: The Affordable Care Act made significant changes to Medicare, including closing the "doughnut hole" in prescription drug coverage and adding preventive services without cost-sharing.
Structure
Medicare is structured into several parts:
- Medicare Part A: Hospital Insurance that covers inpatient hospital stays, care in a skilled nursing facility, hospice care, and some home health care.
- Medicare Part B: Medical Insurance which helps cover doctor's services, outpatient care, medical supplies, and preventive services.
- Medicare Part C (Medicare Advantage): An alternative to original Medicare where beneficiaries can choose plans offered by private companies approved by Medicare.
- Medicare Part D: Prescription Drug Coverage which helps cover the cost of prescription drugs.
- Medicare Supplement Insurance (Medigap): Optional private insurance sold by private companies to help pay for health care costs not covered by Original Medicare, like copayments, coinsurance, and deductibles.
Eligibility and Enrollment
- Automatic Enrollment: Individuals who are already receiving Social Security benefits when they turn 65 are automatically enrolled in Part A and Part B.
- Voluntary Enrollment: For those not automatically enrolled, there is an Initial Enrollment Period, a General Enrollment Period, and Special Enrollment Periods for certain circumstances.
- Premiums and Costs: While Part A is usually premium-free for those who have worked and paid Medicare taxes for at least 10 years, Part B requires a monthly premium, as do Parts C and D.
Challenges and Future Outlook
Medicare faces several challenges including:
- Funding: The Hospital Insurance Trust Fund, which finances Part A, is projected to be depleted by the late 2020s, necessitating reforms.
- Cost Containment: Rising health care costs continue to put pressure on Medicare's budget.
- Quality of Care: Ensuring high-quality care while managing costs is a significant focus for future policy adjustments.
