The Health Insurance Premium Payment Program (HIPP) is a Medicaid program that allows a recipient to receive free private health insurance paid for entirely by their state's Medicaid program. A Medicaid recipient must be deemed 'cost effective' by the HIPP program of their state.
Ultimately, the program was made optional, and its use is minimal. The Omnibus Budget Reconciliation Act of 1990 (OBRA-90) authorized states to implement an HIPP program.
