Navigant (NYSE: NCI) has acquired RevenueMed for $22 million, adding to a wave in health care technology M&A.

RevenueMed, headquartered in Atlanta, provides coding, revenue-cycle management and business-process management services to the health care sector.

Navigant says the acquisition helps it provide end-to-end revenue-cycle business services and expands the company’s services globally.

“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,” says David Zito, managing director and Navigant’s health care segment leader.

Chicago-based Navigant provides business services. In April, the company acquired the life sciences practice of investment bank Leerink Holdings LLC.

Health care providers have been bulking up their technology as the Affordable Care Act brings more patients into the system, and providers are expected to keep costs down and provide better patient outcomes. For more, see 5 Technologies That Drove Health Care M&A in 2014.
