When you think of the saying “leave no stone unturned”, what comes to mind? Maybe something of value was lost, and you were fervently trying to find it or perhaps a loved one was going through an illness, and you were doing all you could to search for a cure. Well, interestingly the saying is derived from an ancient Greek legend from the 1500s. After being defeated, a general buried a large treasure and the Oracle of Delphi encouraged those seeking the treasure to look under every stone. So, how can we apply that saying to the landscape of COVID-19? Well, your ACO must leave no stone unturned when it comes to accurately capturing all your patient’s chronic conditions for risk adjustment. Missing just a few diagnoses annually can attribute to substantial losses when extrapolated across the patient population. Accurately capturing all conditions does not mean limiting the data to what is in your EHR alone. Utilizing all data allows you to view the patient holistically and helps to ensure all chronic conditions are captured. But data alone will not do the trick; to be successful data analytics must be coupled with chart reviews.
