I attended the seminar for ERX NOW and from what I understand it will only work seamlessly with Allscripts products. (a4, healthmatics, and touchworks). However any EMR and PM vendor could design their own interface to ERX NOW. Allscripts would then charge an ongoing interface fee.
As far as the officeally interface, I am having trouble understanding something; AmazingCharts does not keep a payer library. So our data is going to them without our numbers for the different payers. From EZclaim, it lists my insurance # with the appropriate address. So even if we could transmit the file successfully, it would come up short. That is until they have OfficeMate comes out and fills in the missing pieces.
