The contract has been awarded to Infosys Public Services, a US-based subsidiary of Infosys. The Exchange, District of Columbia Access System (DCAS), is a health and human services solution that will provide seamless healthcare coverage while minimising risks, the company said.

"The US District of Columbia awarded Infosys Public Services a one-year contract valued at $49.5 million to develop its new health benefit exchange, a crucial component of the Affordable Care Act," Bangalore-headquartered Infosys said a BSE filing.

Infosys Public Services is the prime systems integrator of this healthcare system transformation that will bring critically important benefits to nearly one quarter million District residents, it added.

The firm is currently designing and implementing the new health benefit exchange and replacing the District's legacy Medicaid and eligibility systems with new technology that will provide a wide array of services in compliance with the new healthcare law, it said.

"This new system will allow the District of Columbia to more easily determine eligibility and enrol individuals, families, and small businesses," Infosys Public Services CEO Eric Paternoster said.
