Health Information Sites to Shut down November 20.

The Centers for Disease Control and Prevention announced Tuesday it will shut down all of its online health and medical services by the end of the month.

The agency will stop providing the websites with payments for providing medical information, as well as allowing them to link to information.

The shutdown will affect nearly 100,000 people and has been criticized by the American Medical Association.

Health Information Services, a joint venture between the CDC and the Department of Health and Human Services, had been offering its website to people who had lost their insurance under the Affordable Care Act.

The new order also requires that Health Information Service websites no longer be able to access federal programs, such as Medicare and Medicaid, and provide information on the Centers for Medicare and Medicare-Part D. The closure is expected to affect 1.3 million people, the CDC said in a statement.

Health information sites that are not part of Health Information Systems will be forced to cease operations and the CDC will refund all user funds.

Health and Social Services Secretary David Shulkin said the decision was “unjustified and contrary to our mission to ensure that Americans have access to the best health care information and services.”

He said the shutdown will not affect people with preexisting conditions, such the uninsured, or those who have been eligible for insurance for several years.

In its statement, the CMS said the health information sites have been providing coverage to millions of Americans and the U.S. population has grown from 7.9 million in 2012 to 11.2 million in 2018.

“It is not possible to continue to provide information and service on health information in a manner that continues to allow for the continuation of the current enrollment in the Health Information System,” the statement said.

The CMS said that the shutdown has impacted more than 3.6 million people and will not impact people who have private health insurance.

The news comes amid a new administration in Washington that has criticized the Affordable Health Care Act, or Obamacare, and vowed to repeal and replace it.

President Donald Trump and several other members of his administration have said the ACA is failing and have threatened to shut down the health insurance marketplaces that cover the majority of Americans.

The announcement comes as the White House is working on a plan to expand coverage under the law.
