There’s usually a spot in every insurance company that considers itself the “innovation center.” Basically, if you incur no costs to them beyond getting you the data, and give them a free trial run on your product, you’ll get your data-sharing agreement.

The data for insurers is in the form of Billings (which come with Diagnosis codes!), which follows a federally-standardized format (check out the Medicare website) and you can get a sample of 5% of Medicare subscribers’ data off the Medicare site without any hoops to jump through.

I want to say, “if you actually know what to do with it, PM me and we can talk details,” but the fact that you don’t already know about this sort of low-hanging fruit suggests you’re from outside the hc sector looking in.
