Catamaran Corp. will add 50 jobs in Indianapolis over the next year to help it provide pharmacy-benefit-management services to the Indiana Medicaid program.

The Lisle, Ill.-based company will open an office downtown Tuesday to kick off its six-year, $60 million contract with the state.

The contract, which officially begins April 1, pledges Catamaran to help Indiana Medicaid control the $800 million it spends every year to provide prescription drugs to Medicaid recipients.

Catamaran will process Indiana Medicaid’s 12.5 million annual pharmacy claims, run clinical and technical call centers, handle electronic prescriptions and manage specialty medications.

The Indianapolis office, located at 150 W. Market St., will house pharmacists, technicians and support staff.

Catamaran was formed by the July merger of Illinois-based SXC Health Solutions Corp. and Maryland-based Catalyst Health Solutions Inc. The publicly traded conglomerate has combined annual revenue of $13 billion and is the nation's fourth largest pharmacy benefit manager.
