Federal Disparity Index (FDI)

The American Indian and Alaska Native population has long experienced a disproportionately high level of health problems compared to other Americans. The lingering health status inequities are troublesome and prompt an important question.

What would it cost to provide equitable health care services to Indian people?

To answer that question, a workgroup of tribal and Indian health leaders developed a pricing model that uses the Federal Employees Health Plan (FEHP) as the primary benchmark. Results from the model are posted here to facilitate consultation with Indian tribes. The Indian Health Service allocates the Indian Health Care Improvement Fund to tribes using results from the model.
