As the strategic IT services partner for IMSS, TCS will provide IT services including application maintenance and support, custom software development, business analysis services and value-added initiatives for the organisation's affiliates, a release said.
TCS won the order following a public bid process and an assessment based on technology and financial parameters,
it added.
"This agreement with IMSS is the largest deal for us to date in Latin America, coming after similar large engagements we have won in recent years with ABN Amro Bank in Brazil, Registro Civil in Chile and Banco Pichincha in Ecuador," TCS Iberoamerica President Gabriel T Rozman said.
"It consolidates our position as the IT partner of choice for major Latin American organisations and also marks our emergence as a key player in the Mexican technology sector," he added.
