Mapping Out COVID-19: Vulnerable Medicare Populations by County

Trella Health has created a heatmap to visualize counties with large populations of patients considered high-risk for serious illness if infected with COVID-19, based on our access to 100% of Medicare Part A & B Fee-for-Service (FFS) claims data. Because chronic obstructive pulmonary disease (COPD) and congestive heart failure (CHF) are two conditions correlated with increased rates of hospitalizations and mortality in COVID-19 cases, we used the number of COPD+CHF patients in a county as the underlying criteria for the heatmap*.


To see detailed information for each county, including number of home health agencies, average Medicare patient age, 2019 population estimate, and number of COPD+CHF patients, fill out the form to the right.

*Counts are based on Medicare FFS patients ages 65+ who had a Physician Part B claim during the most recent four quarters for which Trella has data (Q4 2018- Q3 2019).
