Medicare is a federal health insurance program primarily designed for people aged 65 and older, though it also covers some younger individuals with disabilities. The program is divided into different parts: Part A covers hospital stays, skilled nursing facility care, and some home health services, while Part B covers outpatient care, preventive services, and medical equipment. Part C, also known as Medicare Advantage, allows beneficiaries to receive their Part A and Part B benefits through private insurance plans, often with additional benefits like vision or dental coverage. Part D covers prescription drugs and helps lower the cost of medications. Medicare is funded through a combination of payroll taxes, premiums paid by beneficiaries, and general federal revenue. It provides essential healthcare coverage for millions of Americans, helping to reduce out-of-pocket costs for medical care. However, Medicare doesn’t cover everything, and beneficiaries often face deductibles, copayments, and other out-of-pocket expenses. Many people choose to purchase supplemental insurance, known as Medigap, to help cover these additional costs. The program has undergone various reforms over the years to address issues like rising healthcare costs and the need for better coverage options. Despite its complexities, Medicare remains a crucial safety net for older Americans and those with disabilities, ensuring access to necessary medical care.
