I've spent a lot time around people doing statistics for environmental science, especially regulatory compliance around accidentally killing birds and bats. The unfortunate reality for the statisticians is that every tech thinks they're Henry David Thoreau or something. Like, nobody cares if it was a particular large exemplar of a given species, or that it had magnificent plummage, just write down the species of the carcass and where it was located, and move on. Instead, there's so much variance from (mass produced and standardized) data sheet to data sheet that you can't even use hand writing recognition to automate the process of ingesting the data. Manually entering the data is somebody's whole job, because they've tried to automate it, and failed.

The billing codes exist explicitly to limit the amount of independent thought that can be applied to something that is adequately summarized as "bit by a duck, third visit".
