Health Care Utilization Public Use File
This file is designed to analyze common types of health care use by major categories, including hospital admission, use of ambulance services, clinic visits, and more for Minnesota residents. It presents the data in summarized form by age group and 3-digit ZIP code. Health care utilization information is derived using the place of service codes for professional services and type of bill codes for institutional claims as reported per the Centers for Medicare & Medicaid Service and National Uniform Billing Committee claim reporting standards.
For example, this file permits identifying that in 2013, there were 1,351,628 encounters in a clinic or office setting among children and youth under the age of 18 in West Minneapolis (Zip Code 553), and that the combined spending for patient care related to the visits was about $193 million.
Where the combination of geography, age group and service created cells describing fewer than 11 individuals, the data were rolled up to higher levels of aggregation, consistent with federal data use requirement. In this process, redaction of data occurred first at the geography level and then age grouping. If the rolled up records still described fewer than 11 individuals, they were removed entirely.
Additional redaction occurred, consistent with legislatively established guard rails to prevent identification of providers or health insurance carriers. Generally, records representing fewer than 20 health care providers or fewer than 4 payers were removed.
