Abstract: A method as disclosed herein generates objective projections of aggregate costs from a plurality of providers associated with different aspects of a healthcare procedure. An interface is selectively initiated with a first provider associated with a patient and a respective healthcare procedure.

Upon determining a threshold amount of cost data has been received for each of the different aspects of the procedure, the platform enables selective access by the patient to an aggregated cost projection for the procedure, based entirely on the input data received by the hosted platform for the respective healthcare procedure.
