You may claim an exclusion from the vital signs measure if you believe certain vital signs aren't relevant to your scope of practice. Ideally, a zero numerator would support your exclusion. Achieving a zero numerator, however, isn't always possible based on CMS' requirements for the measure.
The calculator includes historical data. If your practice used to record vital signs, that information still resides in your patient records and is picked up by the calculator. If you claimed an exclusion from this measure and later audited, you may be asked to provide a letter stating that you used to collect vital signs but you no longer do so because vital signs are irrelevant to your scope of practice.
Eyefinity does not recommend removing vital sign information that is already recorded in patients' records.
