[EHR Incentive Programs] A number of measures for Meaningful Use objectives for eligible hospitals and critical access hospitals (CAHs) include patients admitted to the Emergency Department (ED). Which ED patients should be included in the denominators of these measures for the Medicare and Medicaid Electronic Health Record (EHR) Incentive Programs?
There are two methods for calculating ED admissions for the denominators for measures associated with Meaningful Use objectives. Eligible hospitals and CAHs must select one of the methods below for calculating ED admissions to be applied consistently to all denominators for the measures. That is, eligible hospitals and CAHs must choose either the “Observation Services method” or the “All ED Visits method” to be used with all measures. Providers cannot calculate the denominator of some measures using the “Observation Services method,” while using the “All ED Visits method” for the denominator of other measures. Before attesting, eligible hospitals and CAHs will have to indicate which method they used in the calculation of denominators.
