Ancillary Care Management ranked ninth on Inc. magazine's new list of 500 festest-growing companies - and as with so many of Inc.'s selections, it's barely on anyone's radar screen. L.A.-based Ancillary Care helps health plans manage the cost of biotech drugs - an important niche considering how pricey those treatments can be (average claim is $1,500). Annual revenue is $232.6 million and its three-year growth rate is an eye-popping 2,942 percent. The only coverage on this company has been health and medical journals. Somewhat surprisngly, it was the only locally-based company in the top 25 (and that includes all of Southern California). This is always one of the more interesting lists of its kind - and definitely the most reliable - because the companies are private and thus have received very little scrutiny. Inc. is only offering the top 25 companies for free on its Web site.
