A seventeen-year-old girl from Northbridge passed away Thursday night, just hours after her parents got an affirmative answer to the liver transplant she needed.

Nataline Sarkisyan died around 6 p.m. at UCLA Medical Center, where she was kept in vegetative state for weeks, her mother, Hilda said, according to the Los Angeles Daily News.

Nataline had previously suffered from leukemia and received a marrow transplant from her brother. Unfortunately she developed a complication which made her live to fail, according to a letter sent by doctors at the UCLA to her insurance company CIGNA December 11. Doctors were asking the Philadelphia-based company to pay for the transplant, which request was denied.

This decision led to a protest of 150 teenagers and nurses outside CIGNA’s office in Glendale. Therefore, the company reversed its initial decision and said it would approve the transplant, although it maintained that there was not enough medical evidence showing the procedure would work in Nataline’s case.

“Our hearts go out to Nataline and her family, as they endure this terrible ordeal…CIGNA HealthCare has decided to make an exception in this rare and unusual case and we will provide coverage should she proceed with the requested liver transplant,” the company said in an e-mail statement before she died, according to Daily News.

Unfortunately, the girl did not survive to get the transplant. Her mother announced her daughter had passed away and “the insurance is responsible for this.”

Officials with CIGNA could not be reached for comment Thursday night.
