A medical legal evaluation provider asked us to replace "mismatched" and troubling implementation of a billing and collection system.
Since we couldn't find a good "off the shelf" product, we suggested a custom application. Seven months later our solution was up and running. Doctor/patient scheduling, billing, documentation status/inventory tracking and collections were all included in this new version.
The billing and collections department went from 6.5 employees to 1.5 in the 6 months following implementation. Millions and millions of printed invoices and statements became a thing of the past. And the total cost of application was recouped within 6 months.
