An official from the Centers for Medicare and Medicaid Services who helped oversee the rollout of healthcare.gov is retiring, according to the NY Times.

The No. 2 official at the Centers for Medicare and Medicaid Services, who supervised the troubled rollout of President Obama’s health care law, is retiring, administration officials said Monday.

The official, Michelle Snyder, is the agency’s chief operating officer, in charge of day-to-day activities and the allocation of resources, including budget and personnel.

Technology experts who built the website for the federal insurance exchange, HealthCare.gov, reported to her.

Ms. Snyder is the second administration official to depart since problems with the website frustrated millions of people trying to buy insurance and caused acute political embarrassment to Mr. Obama.

The chief information officer at the Medicare agency, Tony Trenkle, stepped down in November to take a job in the private sector.

Marilyn B. Tavenner, the administrator of the Medicare agency, said Ms. Snyder was retiring this week “after 41 years of outstanding public service.”

Snyder’s name came up in congressional hearings in October.

As lawmakers pressed with questions, Cheryl Campbell, senior vice president at CGI Federal, a primary contractor on the healthcare.gov project, indicated that Snyder was a key decision maker from CMS on the project.

And HHS Secretary Kathleen Sebelius initially mentioned Snyder as a key resource in overseeing the project, but quickly clarified and took responsibility herself when pressed further about the project’s shortcomings.

From CNN:

Answering questions at an October congressional hearing, Health and Human Services Secretary Kathleen Sebelius said Snyder was the person in charge of the CMS team overseeing the website.

“So Michelle Snyder is the one responsible for the debacle,” Rep. Marsha Blackburn, R-Tennessee, said.

But Sebelius clarified: “Excuse me, congresswoman, Michelle Snyder is not responsible for the debacle. Hold me accountable. I’m responsible.”

CMS Administrator Marilyn Tavenner indicated that Snyder was prepared to retire in 2012 but stayed on at Tavenner’s request to help with the agency’s work expected in 2013, according to the NY Times.
