March 23rd, marks the fourth anniversary of the signing of the Affordable Care Act.  Since its enactment, millions of Americans have benefited from the law. Here are just four of the reasons we have to celebrate today.

1. 5 million people covered: Since October 1, more than 5 million people have signed up for coverage through the Health Insurance Marketplace.

2. Bending the cost curve: We’ve held down national spending growth in health care to the slowest rate in a half century.

3. Free preventive care: Today, most health plans have to cover recommended preventive services free of charge, benefiting 71 million Americans.

4. Strengthening Medicare: Today, the Medicare program is stronger than ever. Since enactment of the Affordable Care Act, 7.9 million seniors and people with disabilities have saved $9.9 billion on prescription drugs, or an average of $1,265 per beneficiary.

Let’s celebrate millions more covered in 2014. If you know someone who’s uninsured, tell them to sign up today, before the March 31 deadline.
