I would say it can be done a good bit cheaper that $80k,.. I mean wow. I know NTG could spec it out less.
So much of HIPPA is simple common sense with no all users seem to understand. You don'[t keep patient data on the local computer.
IIRC - Bitlocker isn't 'approved' for drive security - Vera Crypt I know isn't. But if you do an RDS session to the server - keeping all the data on the server, you may be fine with that. Keeping everything off the local prevents multiple failure points.
