I know personally that this illegal intimidation also targeted Private Emergency Medicine groups. I work for great yet progressive-leaning contract management group. Our hospital recently changed electronic medical records and we had EM consultants from Minnesota and other area visit. These consultants were members of private EM groups and reported extensive harassment by HHS in auditing all their charts to justify their billing practices.
I had the hunch at the time that these private groups were being singled out and harassed by the government. Now with this latest revelation about IRS, SEC, and HHS, now I suspect even more that these audits were likely politically motivated and unwarranted.
