Xfinity website has a nice article about Obamacare
Health care reform in the coming year will go on a kind of shakedown cruise to test the seaworthiness of America's evolving health care system as it becomes more cost-conscious and quality-focused under the Affordable Care Act.
In 2012, the health insurance law, also known as Obamacare, linked Medicare payments to the quality rather than quantity of care, started penalizing health insurers that charge too much in administrative fees and executive bonuses, and began rewarding good doctors who save Medicare money.
Ahead in 2013, the law will attempt to strengthen America's health care safety net by increasing physician pay and expanding preventive care under Medicaid; bolstering the Children's Health Insurance Program, or CHIP; and launching more streamlined Medicare billing. State insurance exchanges to promote health plan comparison-shopping also face federal certification as they prepare for a scheduled opening in 2014.
Dr. Jeff Cain, president of the American Academy of Family Physicians, says the continued emphasis on primary and preventive care is essential to effective reform.
