The New York City clinic where comedian Joan Rivers suffered a fatal complication during a medical procedure is losing its accreditation at the end of the month.

“Yorkville Endoscopy no longer meets the conditions for a supplier of ambulatory surgical centre services,” government agency the Centres for Medicare Services said.

As of January 31, the Manhattan medical centre will no longer be eligible to receive government funds for services provided to Medicare and Medicaid beneficiaries.

Acid-tongued Rivers, 81, who smashed the male-dominated realm of late-night talk shows and starred with her daughter on E! in Fashion Police, died on September 4.

The city’s medical examiner found she died of brain damage due to lack of oxygen when she stopped breathing during an endoscopy days earlier.

The clinic said in a statement it was continuing to work with all regulatory bodies.

“We intend to communicate with CMS and appropriate authorities to have the decision reversed. Yorkville continues to be a licensed facility and perform procedures while cooperating with the regulatory process,” it said.

The clinic had presented a plan to correct problems uncovered during an investigation after Rivers’s death. But the CMS said yesterday that Yorkville remained deficient in four areas, including “surgical services; quality assessment and performance improvement; governing body and management; and environment”.

Rivers’s death was classified as a therapeutic complication and no negligence was alleged in the agency’s report.

Her daughter Melissa Rivers has hired a prominent malpractice lawyer to investigate.
