HMS Holdings
fastest growing all stars HMS
2012 Fastest-Growing rank: 92
Years on list: 4

Being in the business of detecting waste in the dizzying world of healthcare has paid off for HMS Holdings. The company mines health claims and government and private data and spots inefficiencies, fraud and abuse.

In 2009, HMS made its debut on this list at no. 20 and has held steady each year since. It fell to no. 92 in 2012 but is still seeing healthy gains. For 2011, revenues rose 20.1% to $363.8 million over the previous year.

HMS has also deepened its expertise, with the acquisition of HDI Holdings, which provides improper payment identification services for government and commercial health plans.
