The elderly are vital in the American society. Those aged 50 years old and above own 75% of the country 鈥檚 total assets. 70% of the elderly population has real estates signed on their name. Because of this, the government has been exerting effort to reach out to the elderly people. Laws and policies have been passed in Congress to assist them in their retiring age. One of these is the Medicare program for the American citizens. Under the Social Security Act of 1965, Americans who are aged 65 and above are covered with a health insurance. This program aims to promote the welfare and protection of the elderly through benefits for hospital and medical needs. The Medicare program operates as a single-payer health care under the government 鈥 檚 regulation. It is composed of four parts: Hospital Insurance, Medical Insurance, Medicare Advantage Plans, and Prescription Drug Plans. The benefits acquired from this insurance program are subject to the American doctrine of Medical Necessity. Hence, medical professionals have employed careful research in including every item in each category in the list of benefits. Hospital Insurance covers the hospital expenditures of the elderly for a maximum of 100 days. Costs of the first 20 days are fully covered in the supplement Medicare insurance plans. This includes nursing facilities in a semi-private room, meals, series of tests, and doctor 鈥檚 fees. A patient who stays in the hospital for more than 20 days pays a portion of the hospital bill amounting to $137.50 per day. Medical Insurance includes hospital services which Part A does not include. These involve outpatient hospital facilities such as x-rays, Influenza and Pneumonia vaccinations, blood transfusions, and ambulance transportation. Expensive medications by private physicians are also covered by these supplement Medicare insurance plans like renal dialysis, chemotherapy, and hormonal treatments. In addition, this provides free Durable Medical Equipment and prosthetic devices like walkers, cranes and wheelchairs, artificial limbs and breast prosthesis. Part C and D include benefits which Hospital and Medical Insurance do not cover. Medicare Advantage plans and Prescription Drug Plans are provided through private health insurance plans. These include vision and dental care, health club memberships, and prescription drugs for the elderly. These are channeled through a 鈥渘 etwork of providers 鈥?by the private supplement Medicare insurance plans. Parts C and D are approved by the government in line with the Medicare Prescription Drug, Improvement, and Modernization Act of 2003.
