n November 20, 2020, the Department of Health and Human Services (“HHS”) published sweeping rule changes to the Physician Self-Referral Law (the “Stark Law”) and the Federal Anti-kickback Statute (“AKS”). HHS previously indicated that the new final rules for the Stark Law and AKS would be not published until summer of 2021, so the announcement on November 20, 2020 came as quite a surprise. Most of the changes took effect on January 19, 2021. Physicians should be aware of the new opportunities and new obligations resulting from these changes.
