William H. Stiles

        Counsel

        Will enjoys a good challenge. Whether it involves taking up Telemark skiing as a 40-something or pressing a novel legal theory, his approach is simple: a can-do attitude, creative thinking, good old-fashioned hard work, and, most importantly, keep it fun. (Yes, even Medicare and Medicaid reimbursement can be fun.)

        Although most people’s eyes glaze over at the mere mention of Medicare and Medicaid regulations, Will has a strange infatuation with ensuring that his health care industry clients are correctly reimbursed for the important services they provide. He enjoys appearing before the Medicare Provider Reimbursement Review Board (as well as state Medicaid agency hearing officers) and relishes the opportunity to poke holes in governmental overpayment determinations. He speaks fluent Medicare and Medicaid, including the unique dialects of DSH, TEFRA, CAH, GME, SCH, MDH, Bad Debts, and TPL. Will’s approach has helped his clients obtain well over $100 million of additional Medicare and Medicaid reimbursement (and has saved his clients tens of millions more defending against overpayment claims).

        A frustrated author at heart, Will believes that a compelling story lies beneath even the most complex litigation, and success often depends upon teasing out a simple message and sharing it through well-prepared witnesses, strong supporting data, and crisp writing.

        Outside the office, Will enjoys creating a dynamic and supportive community by volunteering time with nonprofit agencies, boards, and committees. In 2012, Will helped to create the WinterKids’ Downhill 24, a 24-hour team alpine ski race that raises hundreds of thousands of dollars each year to help children lead healthy lives.

        Will is passionate about his family, travel, food, and winter. A die-hard “Sugarloafer” (ask him), Will has not yet given up on his dream of appearing in a Warren Miller ski movie.
