Mr. Obama accepted Ms. Sebelius’s resignation this week, and on Friday morning he will nominate Sylvia Mathews Burwell, the director of the Office of Management and Budget, to replace her, officials said.
The departure comes as the Obama administration tries to move beyond its early stumbles in carrying out the law, persuade a still-skeptical public of its lasting benefits, and help Democratic incumbents, who face blistering attack ads after supporting the legislation, survive the midterm elections this fall.

The president is hoping that Ms. Burwell, 48, a Harvard- and Oxford-educated West Virginia native with a background in economic policy, will bring an intense focus and management acumen to the department. The budget office, which she has overseen since April of last year, is deeply involved in developing and carrying out health care policy.
“The president wants to make sure we have a proven manager and relentless implementer in the job over there, which is why he is going to nominate Sylvia,” said Denis R. McDonough, the White House chief of staff.
Administration officials told The New York Times that the decision was Sebelius's and she wasn't being forced out, that she had been talking with President Obama about her future and about this transition since last month. “What was clear is that she thought that it was time to transition the leadership to somebody else,” McDonough told the paper.
