I'm in health-tech myself and have a bit of background with the terminology process. Is this using CPT codes for the search? If so, you might want to look at improving some of the functionality, since a lot of these are abbreviated, and unless you are a complete wonk like I am, patients may or may not fully understand the abbreviations. Nice job though with the layout.
We figured the CPT codes would be too confusing for users, we just have the hcpcs descriptions.
Where are you located in the health-tech-osphere?
