Just as the ruling has split medical organizations -- albeit unevenly -- it has also polarized physicians. However, the doctors contacted by ABC News expressed relief over the decision.
"This is great news for our patients and for our entire health care system," said Dr. Gary Lyman, professor of medicine at Duke University in Durham, N.C. "The ACA contains many features that will protect current and future patients from the inequities in our health care system. Many of the benefits are yet to be realized but hold great promise for all of us and the next generation of Americans."
"This is an historic day for American health care," said Dr. Ashish Jha, professor of health policy at the Harvard School of Public Health in Boston. "The Supreme Court has decided that ultimately, these are policy decisionis and it is not the job of the court to decide how to best achieve health care coverage for all Americans."
Other experts see this as a victory for politicians on both sides of the aisle.
"The decision can be seen as a win for both sides. Obama's law stands, and conservatives don't have to worry about a precedent that expands federal power," said Robert Field, professor of health policy at Drexel University in Philadelphia.
Health insurance organizations, however, remain wary of the new law.
"The law expands coverage to millions of Americans, a goal health plans have long supported," said Karen Ignagni, CEO of America's Health Insurance Plans, "but major provisions, such as the premium tax, will have the unintended consequences of raising costs and disrupting coverage unless they are addressed."
