Senator Grassley and Others Propose Amendments to the False Claims Act

August 2, 2021 | Blog | By Samantha Kingsbury, Brian Dunphy, Laurence Freedman

Earlier this week, a bipartisan group of Senators led by Senator Chuck Grassley (R-Iowa) introduced two pieces of proposed legislation, one of which would amend the existing False Claims Act (FCA) and the other of which would amend the Program Fraud Civil Remedies Act of 1986 (the PFCRA) to create the Administrative False Claims Act of 2021 (AFCA). The AFCA would focus on smaller claims than does the FCA. Senator Grassley described the bills as being intended to “help recoup even more money by clarifying confusion after the Escobar case” and as being needed more than ever “to fight the significant amounts of fraud we are already seeing” related to the trillions of dollars Congress has appropriated for COVID relief.

FTC Engages in First Enforcement Action under COVID-19 Consumer Protection Act

April 27, 2021 | Blog | By Joanne Hawana, Samantha Kingsbury

In its first exercise of a newly granted authority, the Federal Trade Commission (FTC or the Commission) on April 15, 2021 charged a St. Louis-based chiropractor and his company (the Defendants) with violating the COVID-19 Consumer Protection Act (the COVID-19 Act) and the Federal Trade Commission Act (FTC Act).  The Commission’s allegations focus on the deceptive marketing of products containing Vitamin D and Zinc as being scientifically proven to treat or prevent COVID-19 and as being equally as effective as or more effective than currently available COVID-19 vaccines.

As our readers know, we have long been closely watching False Claims Act (FCA) cases across the country alleging the submission of false claims based on the lack of medical necessity, particularly as a possible circuit split seemed to be developing with respect to requiring “objective falsity” to allege such FCA violations.  And we have likewise been waiting to see if the issue will be decided by the Supreme Court.  On February 22, 2021, we got an answer – at least for now – when the Supreme Court denied a petition for certiorari in RollinsNelson LTC Corp. et al v. U.S. ex rel. Winters, a FCA case out of the Ninth Circuit in which the defendant was accused of submitting claims to Medicare for medically unnecessary hospital admissions (which we have been following since last year).

Mintz’s Health Care Enforcement Defense team has reviewed the key policy issues, statistics, settlements, and court decisions from 2020, and in this report we reflect on those developments and also predict the trends in health care enforcement in 2021 and beyond.

A few weeks ago, we posted about a publication by the Office of Inspector General for the U.S. Department of Health and Human Services (OIG) of responses to certain frequently asked questions (FAQs) received from the health care community regarding regulatory flexibility for providers that needed it to adequately respond to COVID-19 concerns.  This flexibility specifically relates to the OIG’s administrative enforcement authorities, including the federal Anti-Kickback Statute (AKS) and Civil Monetary Penalties Law prohibiting beneficiary inducement (Beneficiary Inducement CMPL).

As many of our readers know, as a result of the public health emergency caused by COVID-19, effective March 1, 2020, the U.S. Department of Health and Human Services (“HHS”) issued blanket waivers of its authority under Section 1877(g) of the Social Security Act (which authorizes the imposition of certain sanctions for violations of the Stark Law) with respect to 18 categories of remuneration and/or referrals (the “Blanket Waivers”).

On March 16th, Attorney General William Barr issued a memorandum to all United States Attorneys directing each U.S. Attorney’s Office (USAO) to “prioritize the detection, investigation, and prosecution of all criminal conduct related to the current pandemic,” noting that “the pandemic is dangerous enough without wrongdoers seeking to profit from public panic.”  It appears that USAOs have wasted no time in prioritizing such cases, as the owner of a Georgia-based marketing company that generated leads for medical-testing companies was arrested earlier this week and charged with conspiracy to commit health care fraud and conspiracy to violate the Anti-Kickback Statute.
