By any chance have you used GNU Health[0] at all? I'm guessing no since it's uncommon in the US/NZ, but figured I'd ask just in case. Curious what your impression of it would be as an MD.
EHRs in the USA, Germany and other countries with numerous health insurance providers are primarily there to ensure every service and tools used is billed fully (or overbilled).
GNU Health’s support for the whole set of pre-authorization, billing, payment, and related transactions seems to be...generating manual invoices.
Because people stand to lose profit if GNU Health is used.
