Medically Underserved Population (MUP) Guidelines

The Medically Underserved Population (MUP) designation involves application of the Index of Medical Underservice (IMU) to data on an underserved population within an area of residence to obtain a score for the population group. Population groups requested for MUP designation should be those with economic (low-income or Medicaid-eligible populations), cultural and/or linguistic access barriers to primary medical care services.

The MUP process involves assembling the same data elements and carrying out the same computational steps as stated for MUAs. The population is now the population of the requested group within the area rather than the total resident civilian population of the area. The number of full-time equivalent (FTE) primary care physicians includes only those serving the requested population group.

Exceptional Designations
A population group which does not meet the established criteria of an IMU less than 62 can be considered for an Exceptional Designation if "unusual local conditions which are a barrier to access to personal health services, or the availability of personal health services" exist and are documented.
