Parallon CEO out

Former UnitedHealth exec named to job less than two years ago

The CEO of Parallon Business Solutions is no longer with the HCA Holdings division he led for less than two years.

Mike O'Boyle left his post last week at Parallon, which is home to revenue cycle management, staffing and other back-office functions HCA uses itself and markets to other providers. The 56-year-old joined Nashville's largest company in January 2012 after leading UnitedHealth Networks, a division of the large insurer, for four years.

Taking O'Boyle's place on an interim basis is CFO Chris Taylor, pictured, who was brought on board about a year ago. Previously, Taylor held the CFO spot at HCA's TriStar Health division.

O'Boyle's departure, which was first reported by The Tennessean, comes despite apparent satisfaction from HCA's top brass about Parallon's progress. On the company's Q3 conference call Tuesday, CFO Milton Johnson said "things are going well" at the division, pointing out double-digit growth at its HealthTrust purchasing subsidiary and noting that its revenue cycle management business also is putting up a good performance — thanks in part to its work with fellow local LifePoint Hospitals.

"I continue to think that over the coming years, we'll have many opportunities to grow through Parallon," Johnson said.

Shares of HCA (Ticker: HCA) were down about 2 percent to $45.60 in mid-day trading Wednesday. Year to date, they're up some 50 percent.
