Last year in January, the Bangalore-headquartered firm's US subsidiary, Infosys Public Services, was awarded the $49.5 million contract from the District of Columbia to develop its health insurance marketplace - DC Health Link.
"The US District of Columbia has extended its contract with Infosys Public Services, a US-based subsidiary of Infosys," the firm said in a statement.
Under the new agreement, Infosys Public Services will modernise the legacy eligibility system and additional federal and local health and social programmes for the District of Columbia, it added.
Infosys Public Services will leverage the foundational capabilities developed in 2013 to enable the district's agencies to collaborate with their constituents to achieve sustainable health and social benefit outcomes, it said.
"The District is a leader in implementing the new healthcare insurance mandates and insurance marketplace," Infosys Public Services president and chief executive Eric Paternoster said.
Infosys Public Services provides consulting, systems integration, IT services, business process services, products and platforms solutions, to health insurers and providers, government healthcare, federal and state government.
