Editor’s Note: This story has been updated with a new statement from Golden Living.

A lawsuit against nursing home operator Golden Living has been expanded to include 11 additional facilities, the Pennsylvania Attorney General’s Office announced this week.

The facilities were added in response to more than 350 complaints filed against Golden Living facilities since the original lawsuit was filed in July, according to Pennsylvania Attorney General Kathleen Kane. The suit alleges that Golden Gate National Senior Care LLC failed to provide basic services to residents, falsified care records, deceived state Department of Health inspectors and left facilities understaffed.

Golden Living officials have said they plan to “vigorously” fight the claims, which they claim are “retaliation” for challenging Kane in the lawsuit.

“Golden Living remains confident that the claims made by the Attorney General are baseless and wholly without merit,” wrote company officials in a statement. “All of our LivingCenters are in compliance with legal requirements, as determined by the two agencies that have oversight of our industry – the Centers for Medicare & Medicaid Services and the Pennsylvania Department of Health. We vigorously are defending our reputation and that of our caregivers who serve our patients and residents.”

The amended lawsuit now includes 25 of the 36 facilities Golden Living operates in Pennsylvania. The company currently ranks as the third-largest nursing facility provider, with 295 facilities in 21 states, comprising more than 30,000 beds, according to data from the American Health Care Association.
