Chronic Conditions – Multiple Chronic Conditions (Medicare Population)

Methodology

The rate of Medicare beneficiaries with multiple chronic conditions (MCC) is acquired for 2007 – 2019 from Centers for Medicare and Medicaid Services (CMS) Chronic Conditions Warehouse. Data are reported for Medicare Fee-for-Service Beneficiaries with two or more of the 21 standard chronic conditions. The data used in the chronic condition reports are based upon CMS administrative enrollment and claims data for Medicare beneficiaries enrolled in the fee-for-service program. Beneficiaries who died during the year are included up to their date of death if they meet the other inclusion criteria. Prevalence is presented for MCC based upon counting the number of chronic conditions from the set of 21 chronic conditions and grouping into four categories (0-1, 2-3, 4-5, and 6 or more). Enrollment data are acquired for 2007 – 2019 from Centers for Medicare and Medicaid Services (CMS) Medicare Geographic Variation Public Use File. The rate of MCC prevalence is calculated by CMS by taking the beneficiaries with two or more conditions divided by the total number of beneficiaries in the fee-for-service population, expressed as a percentage.

This CMS table has developed data that enables researchers and policy-makers to better understand the burden and complexity of chronic conditions among Medicare beneficiaries and can be used to identify high risk Medicare beneficiaries. Data is presented for U.S. counties and U.S. states, including Washington, DC, Puerto Rico, and the U.S. Virgin Islands, and is available for the years 2007-2019.
