CMS Finalizes Changes Expanding the Scope of the Open Payments Program

November 18, 2019 | Blog | By Brian Dunphy, Rachel Yount

On November 15, 2019, the Centers for Medicare & Medicaid Services ("CMS") finalized changes to the Open Payments Program as part of the CY 2020 Physician Fee Schedule Final Rule. Perhaps most importantly, CMS broadened the list of Covered Recipients. Starting for data collection for CY 2021, manufacturers will be required to track and report payments and transfers of value made to physician assistants, nurse practitioners, clinical nurse specialists, certified registered nurse anesthetists, and certified nurse midwives. CMS also added three new nature of payment categories – debt forgiveness, long-term medical supply or device loan, and acquisitions. CMS also consolidated the two payment categories for continuing education programs – accredited/certified and unaccredited/non-certified – into one payment category for all continuing education programs. Lastly, in a move expected to impose a substantial burden on medical device manufacturers, CMS added a reporting requirement for the ‘device identifier’ component of the unique device identifier for devices and medical supplies.

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.

The Third Circuit Court of Appeals recently dismissed a relator’s False Claims Act (“FCA”) case under the pre-Affordable Care Act (“ACA”) version of the public disclosure bar. The court decided in U.S. ex rel. Denis v. Medco that to escape the FCA’s public disclosure bar by qualifying as an “original source” under the pre-ACA version of the FCA, a relator must have first-hand, non-derivative knowledge of conduct giving rise to the FCA claim.

FCA Relator and U.S. Weigh in on Defendants' Argument that the FCA is Unconstitutional

May 9, 2019 | Blog | By Samantha Kingsbury, Brian Dunphy

As part of our ongoing discussion of the Polukoff False Claims Act (FCA) qui tam case (involving allegations that certain heart procedures performed by a cardiologist, and billed for by two hospital defendants, were not medically necessary), we reported in February that some defendants filed a petition for a writ of certiorari with the United States Supreme Court.

The Supreme Court denied a petition for certiorari last Monday in U.S. ex rel. Prather v. Brookdale Senior Living Communities, Inc., No. 17-5826 (6th Cir. June 11, 2018), again declining to revisit or clarify the False Claims Act's “materiality” standard set forth in its 2016 decision in Universal Health Services v. United States ex rel. Escobar, 136 S. Ct. 1989 (2016). 

In Prather, the relator alleged that defendant Brookdale Senior Living Communities, Inc. (Brookdale), a home health provider, submitted bills for medical services that were “untimely” signed and certified by physicians in violation of Medicare regulations.  When submitting Medicare claims, Brookdale purportedly did not obtain the required physician certifications attesting that the medical services provided by Brookdale were necessary until months after establishing a patient’s plan of care.  Because Medicare regulations under 42 C.F.R. § 424.22(a)(2) require physician certifications “at the time the plan of care is established or as soon thereafter as possible,” the relator alleged that Brookdale’s untimely certifications rendered the claims false under the implied false certification theory.  The district court dismissed the complaint on materiality grounds, holding that the noncompliance was insubstantial and that the relator failed to allege that the government had ever denied a claim based on a violation of the timing requirement under the Medicare regulations.

Last year, as we previously discussed, there were two significant Department of Justice (DOJ) policy developments that are applicable to False Claims Act (FCA) litigation: (1) the “Granston Memo” (issued by DOJ Civil Fraud Director Michael Granston), which set forth direction for DOJ’s exercise of its authority to dismiss declined qui tam FCA cases; and (2) the “Brand Memo” (issued by Associate Attorney General Rachel Brand), which instructed DOJ’s FCA litigators not to use any sub-regulatory guidance to create legal obligations.
