Two Central Texas-based businesses join together to improve patient and practice experience.

AUSTIN, TX — The Austin Diagnostic Clinic (ADC) announces that back-office revenue cycle business services for the 62 year-old clinic will be transitioned to Dell Services by September 2015.

In order to maximize efficiencies, reduce complexity and off-set the continuing reductions in insurance reimbursements, ADC, the second largest multi-specialty clinic in Central Texas [1], will transition its back-office revenue cycle business services to Round Rock-based Dell and its Healthcare Services Group. Dell has been ranked five straight years by Gartner as No. 1 Worldwide IT Services provider in Healthcare Providers based on revenue.

“We are very excited about this transition. Dell brings the expertise and competitive edge that ADC needs to succeed in healthcare today,” said ADC’s Chief Executive Officer Ghassan Salman, M.D. “The Clinic will have access to a worldwide infrastructure and resources that will scale with our business needs as we continue to grow and expand services for our patients.”

Patients and physicians will benefit from a seamless transition and increase in the quality of services ADC will provide as a result of the change, noted Salman.

“Dell is pleased to bring its deep healthcare expertise and provider experience to help ADC focus on its mission of providing compassionate care and excellent service. Both organizations believe that information-driven healthcare can improve quality of care for the patients we serve, and we look forward to a long and fruitful collaboration with ADC,” said Sid Nair, vice president and global general manager, Healthcare and Life Sciences, Dell Services.
