Case Mix Index (CMI) Impact 101

How Case Mix Index Is Impacted by CDI

Three major factors influence a hospital’s Case Mix Index (CMI):

Number of patients with a cc/mcc divided by the total number of patients

Small changes can make a significant financial impact, especially when highly-weighted surgical case volume decreases

These are the annual relative weight changes applied by CMS each fiscal year

CDI programs can only impact one major factor: capture rate. By helping CDI teams correctly document patient conditions, Iodine helps hospitals' achieve a more accurate capture rate, which impacts CMI.
