King & Spalding has grown its healthcare practice in Washington with the addition of a former Department of Health and Human Services official.
Mark Polston, formerly deputy associate general counsel for litigation in the Centers for Medicare and Medicaid Services division of HHS, joins King & Spalding as a partner.
During the seven years Polston spent with the agency, he focused on litigation involving Medicare, Medicaid, the Affordable Care Act and healthcare fraud.
In May, the firm added two lateral healthcare attorneys, Donna Thiel and Theresa Weir, who joined as partner and counsel, respectively.
In an interview, Polston said that he came to HHS with a false claims and fraud background. There, he worked on various litigation involving the government's average wholesale price. But Polston's most memorable moment was the work he did with the team of government attorneys on the Affordable Care Act.
"The ability to work on a case of such historic and legal significance was the highlight of my career," Polston said.
Now that he's in private practice, Polston will put his experience with the government to work for clients. "I think that the backbone of my practice will be to advise and counsel and sometimes litigate on behalf of hospital providers navigating through the complex rules of the Medicare program," he said.
