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.

The Ninth Circuit Court of Appeals recently allowed a False Claims Act (FCA) case based on an alleged lack of medical necessity to proceed, rejecting the lower court's decision that subjective medical opinions about the necessity of hospitalization cannot be "objectively false." The Ninth Circuit joins several other circuits (including the Third Circuit, which recently issued the Druding decision that we posted about a few weeks ago) in reaching this decision, which has been a rapidly evolving area of FCA law.

Landmark AseraCare Case Finally Ends in Settlement

March 2, 2020 | Blog | By Samantha Kingsbury, Brian Dunphy, Laurence Freedman

As many of our readers know, the AseraCare case was closely watched over the last several years because of its significance to efforts by the Department of Justice (DOJ) to allege that submission of claims for services lacking “medical necessity” violate the False Claims Act (FCA) as well as to efforts by providers to defend such cases. On Wednesday, we learned that the AseraCare case has reached its dramatic conclusion with an agreement to resolve $200 million in alleged damages for the agreed amount, as reported by AseraCare, of $1 million.

On Monday, the U.S. Court of Appeals for the Eleventh Circuit issued its long-awaited and closely watched decision in United States v. AseraCare Inc.. The court ruled that a claim cannot be deemed false under the False Claims Act (FCA) based on a difference in clinical judgment.  Instead, there must be proof of an objective falsehood. More than three years have passed since the U.S. District Court for the Northern District of Alabama issued the series of rulings that gave rise to the Eleventh Circuit case.

Insys Bankruptcy Filing Immediately After Global Settlement Triggers Powerful Remedies

June 25, 2019 | Blog | By Samantha Kingsbury, Laurence Freedman

Over the last two years, much of the healthcare world has been watching the government’s prosecution of Insys Therapeutics for its sales and marketing practices related to its Subsys spray.  Subsys is powerful and highly addictive fentanyl spray (administered under the tongue) that was approved by the FDA in 2012 for the treatment of persistent breakthrough pain in adult cancer patients who were already receiving, and tolerant to, regular opioid therapy.  On June 5, 2019, DOJ announced a global resolution with Insys, including criminal pleas, a Deferred Prosecution Agreement (DPA), a civil settlement agreement, and a Corporate Integrity Agreement (CIA).  Then, on June 10, 2019, Insys filed for bankruptcy protection, which triggered DOJ and HHS’s ability to upend these agreements and impose powerful criminal, civil, and exclusion remedies against Insys. While much of the coverage of this case over the last few years has focused on the high-profile prosecution and conviction of company executives (including Insys’s founder) and other employees who were accused of paying kickbacks to prescribers in exchange for increased prescriptions and increased doses of Subsys, the resolution of this case on the corporate side has proven to be equally fascinating.

Kingsbury co-authored a book published by the American Bar Association examining the federal Anti-Kickback Statute, one of the best-known federal fraud and abuse statutes, which prohibits transactions intended to induce or reward referrals for items or services reimbursed by the federal health care programs.
