You have to actually report a percentage. Per the guidelines:
"Factor 5: To provide consistent access and help understand true demand, practices
monitor no-show rates. No-show rates may be calculated by taking the number of
patients who did not keep their pre-scheduled appointments during a specific period of
time (i.e. a session or a day) divided by the number of patients who were pre-scheduled
to come to the center for appointments during the same period of time (Primary Care
Development Corporation)."
