American Access Care Holdings LLC (AAC) has entered into a civil settlement agreement with the government, according to the office of Deirdre M. Daly, United States Attorney for the District of Connecticut.

AAC will pay $3,594,791 to resolve allegations that it violated the False Claims Act.

The violations allegedly occurred while AAC was operating a number of vascular access centers around the country, one of which was in Fairfield.

Among other services, vascular access centers address complications with dialysis access for patients with kidney disease. The government alleges that, between January 2007 and September 2011, AAC improperly billed Medicare and Medicaid for multiple percutaneous transluminal angioplasties performed during the same patient encounter. The government also alleges that, between October 2005 and September 2011, AAC improperly submitted claims to Medicare and Medicaid for procedures performed during follow-up visits that were not medically necessary.

“It is imperative that all health care providers bill only for appropriate and necessary medical treatments and bill for such services accurately and honestly,” Daly said in a statement. “The U.S. Attorney’s Office will vigorously investigate any provider that submits fraudulent claims to Medicare or Medicaid as this misconduct cheats the system, increasing the cost of health care for all of the rest of us.”

The Connecticut settlement is related to a parallel resolution of claims against AAC by the U.S. Attorney for the District of Rhode Island, and follows a third settlement against the company in the Southern District of Florida, in the case United States ex rel. Souza v. American Access Care of Miami LLC.

The violations in questions were committed prior to AAC’s 2011 merger with Fresenius, according to Daly’s office.
