CHICAGO – Feb. 23, 2015 – Navigant (NYSE: NCI) announced today that it has acquired RevenueMed, an Atlanta-based provider of coding, revenue cycle management, and business process management services for the healthcare sector. The acquisition further strengthens Navigant’s position as a leading provider of end-to-end revenue cycle business process management services and expands the Company’s platform to include global, offshore capabilities for its clients.

RevenueMed has developed several proprietary software and process tools to support financial and back-office operations of healthcare providers and leverages a wholly-owned delivery network in India to operate as an extension of the client’s business office. The company appeared for six consecutive years on Inc. Magazine’s list of Fastest Growing Private Companies in the United States.

“We are delighted to announce the addition of RevenueMed, which augments our business process management client offerings and further positions Navigant for long-term, sustainable growth,” stated Julie Howard, Navigant Chairman and Chief Executive Officer. “Our continued investment in business process management services builds on and complements our deep consulting expertise. The addition of RevenueMed provides greater scalability in a fast growing sector to support our revenue and profitability growth goals. We welcome the RevenueMed team to Navigant.”

RevenueMed was founded in 2002 by Chief Executive Officer, Michael von Grey. RevenueMed’s medical coding capabilities are delivered by professionals that include physicians and nurses whose knowledge provides a strong foundation for the market’s evolution to complex ICD-10 coding. Day-to-day operations will continue to be managed by von Grey and his current leadership team, and will be part of the Navigant Cymetrix business.

“The Healthcare sector is facing unprecedented pressure as it navigates growing complexities while delivering better outcomes and value to patients,” said David Zito, Managing Director and Navigant Healthcare segment leader. “As we assist health systems to position themselves

for the future amidst market and regulatory changes, we expect continued high demand for business process solutions. Our clients are focused on optimizing operational efficiencies and we look forward to working with them to develop solutions that focus on delivering quality care and better patient outcomes in an environment of declining reimbursement.”

“We are joining Navigant at such an important time – for our firm, for Navigant and for the Healthcare sector overall,” said RevenueMed Chief Executive Officer, Michael von Grey. “The convergence of our capabilities and resources with the robust business process management offering already in place at Navigant will create more options and solutions for a broader client base.”
