"HealthPia's GlucoPhone, which combines a glucometer with a cell phone, is being used by fewer than 100 patients nationwide since FDA granted it premarket approval last year. HealthPia charges $79 as part of an introductory package for its GlucoPhone, as long as patients also pay for the service from its selected
telephone carrier, LogicMobile. Patients also have to purchase testing strips
that must be used in conjunction with the phone, although Medicare reimburses
patients for the strips."
