Federal officials reported last month that Life Care had failed to notify state officials about the increasing rate of respiratory infections among residents, failed to rapidly identify and manage ill residents and failed to have a backup plan after the facility’s primary clinician fell ill. C.M.S. said that those urgent issues have since been resolved, but that Life Care would also need to demonstrate compliance on other issues, including record-keeping and its handling of safety and quality strategies.

“If L.C.C. of Kirkland does not correct all deficiencies and return to full compliance by September 16, 2020, then C.M.S. will terminate your facility from participating in the Medicare/Medicaid program,” wrote Patrick Thrift, a C.M.S. enforcement official in Seattle.

A spokesman for Life Care did not immediately return a message seeking comment. The company can appeal findings from both the federal and state reports.

Life Care emerged a month ago as an early center of the coronavirus outbreak in the United States. Two-thirds of the facility’s residents and dozens of staff members have tested positive for the coronavirus. Officials have identified 37 people linked to the facility who have died.
