I am no expert on this but can hopefully point you in the right direction based on what I learned recently (here on hn!)

Assuming you are in the USA- they just passed a law where all hospitals will need to publicly publish the list of all the procedures they do and the cost. Until now this,as I understand this was guarded very tightly and the common person would never get it. This information is maintained in what is called a “chargemaster” (charge description master). So I am thinking you can possibly download a few chargemasters abd then process it via queries etc and get a longer list of procedures. Hopefully this set you in the right direction.
