Mott's cardiology and heart surgery specialty took the hospital's highest rating. According to the U-M Health System, the Mott Congenital Heart Center performs 850 operations a year and is the second-largest congenital heart program in the nation.

In December Mott and the Von Voigtlander Women's Hospital moved into a new 1.1 million square foot, $754 million facility that took more than five years to plan and build. It was the largest construction project in U-M history and officials said the move was vital to Mott staying relevant in pediatric care.

U.S. News has been ranking children's hospitals since 2007 and reworked how it calculates rankings in recent years. U.S News surveyed 178 pediatric centers this year, gathering data on patient outcomes, infection rates, surgical volume, nurse-to-patient ratio and reputation.
