For example: The article notes, For purposes of qualifying for the e-prescribing incentive payment for 2009, an eligible professional will be considered a successful e-prescriber if he/she reported the applicable e-prescribing quality measure in at least 50 percent of the cases in which such measure is reportable by the eligible professional during the reporting period.
