> That's really interesting, because I had a customer that did nothing but provide medical billing services, and about 15 years ago when the industry was moving from ICD-9 to ICD-10, that customer seemed really focused on their billing coders learning ICD-10. I mean, sure? You can't bill for a service without a diagnosis code that justifies the service. Anyone who does medical billing is going to need to be able to format that data. But ICD codes are not the codes that insurers are billed for - billing codes are completely separate and not even determined by the same party.
