There is substantial variation and low correlation in healthcare spending across Medicare, Medicaid, and private insurance plans within different US regions, a study published in JAMA Network Open found.
The US spends around $3.8 trillion per year on healthcare funded by Medicare, Medicaid, and private insurers. However, spending and healthcare utilization are rarely the same for all three payers.
Researchers used data from the Healthcare Cost Institute (HCCI), Medicare fee-for-service claims, and the Transformed Medicaid Statistical Information System Analytic Files to determine the correlation in regional spending and utilization across the three payers.
