Yorkville Endoscopy in New York City could lose their license. The Manhattan clinic was under investigation over a botched surgery that led to Joan Rivers' death. The comedienne stopped breathing during an unplanned biopsy procedure.

"Yorkville Endoscopy LLC no longer meets the requirements for participation as a supplier of services in the Medicare program." said the Centers for Medicare and Medicaid Services, a subsidiary of the Health Department which certifies ambulatory surgery facilities.

The clinic could be closed for faults in four categories required for accreditation: governing body and management, surgical services, medical staff and patient rights. The license will be terminated on January 7, 2015 if the clinic can't prove they have corrected the lapses.

"The Center has been working collaboratively with appropriate government regulatory agencies to ensure complete compliance with all regulations," a rep for the clinic tells ABC News. "The Center remains open and will continue to collaborate with all accreditation and government regulatory agencies to ensure quality care."

Rivers, 81, passed away on September 4 after a week of hospitalization. She was rushed to hospital and put into a medically-induced coma after the botched procedure. According to New York City Medical Examiner's Office, she died from low blood oxygen to the brain.
