Chargemaster.csv.hash.SHA and Chargemaster.metadata.json.hash.SHA
These files are hashes of the downloaded files so that you can be sure that what you downloaded is the same as what the hospital released.
To verify them run a command line shasum program to create a new hash. Something like
shasum Chargemaster.csv shasum Chargemaster.metadata.json
should work. If you are going to build a spider to repeatidly check to see if chargemaster files have changes
A JSON formatted file with the following contents:
