What's in it for Me?
ICD-10 is "granular." It lets researchers, insurance companies, the feds, and anyone else who gets their eyes on the data do great things. This data is valuable. To get this data, I, a solo practitioner, must buy software, recode the diagnosis for every patient, code it again the next visit as the specificity has changed, and so on.
And what am I paid for providing this valuable data? Why, nothing at all! In fact, if the computer at the other end doesn't like my code, I don't get paid for my work. And the payments here in primary care land are, shall we say, inadequate for the work we do, let alone for the data processing services we are required to provide for free in order to get our pay.
I say it's spinach, and I say the heck with it.
