A NHS hospital failed to chase up a bill of £145,000 it should have charged a Nigerian woman who had quintuplets after travelling to Britain.

Bimbo .............., 37, underwent a complex caesarean section in 2011 but did not pay any of the cost of the operation and neo-natal care for her five babies.

But it has now emerged that Homerton University Hospital, in east London, will not pursue her for the outstanding bill.

The hospital involved has admitted it sent only one request for payment, more than six months after Miss ,,,,,,,,,,,,,,,,,, left the hospital – and had failed to take any further action when it was returned unpaid.

Miss .............. has since returned to her home city of Lagos, where she is a successful make-up artist.

She said: “I have never received my bill. If I had it, I would pay it.”

It follows claims by NHS whistleblowers that managers are instructing them to turn a blind eye to health tourists because it is ‘too much trouble’ to chase them for money.

According to NHS estimates, only around 16 per cent of the cost of treating foreigners who travel to Britain to receive treatment is ever recouped.

Miss ,,,,,,,,,,,,,,,,,,,, obtained a visitor’s visa soon after discovering she was pregnant in 2010, travelling to the UK to stay with her younger sister, Stella, early in her pregnancy.

She gave birth to two boys and three identical girls at Homerton Hospital in Hackney, in April 2011 – seven weeks premature. She had a complex caesarean and remained in hospital for almost two weeks after the birth at a cost of £145,000 to UK taxpayers.

Although her visa expired, Miss ................ continued living in her sister’s flat in Poplar, east London, after the births and did not return home until February 2013.

Miss ............... children are now four years old and attending a private school.

She told the Mail: “What is it that’s my fault? I don’t understand.

“They blamed me that I came to the UK and I just came to use the system, which I did not do.

“If it (health tourism) is a problem in the UK, you should talk to the NHS. I have never received my bill. If I had it, I would pay it.”

She said that she was allowed to stay in the UK without needing to ask and without having to apply.

“I did not want to stay... it was just my situation,” Miss ..................... added.

It is understood Miss .................. is separated from her wealthy husband, ......................., but he is still involved in the children’s lives and is believed to pay for their education.

Miss ............. is understood to have left the UK voluntarily in February 2013, following contact with the Home Office. It is believed she has been banned from returning to Britain for five years.

In the UK hospitals try to claw back the cost of treating foreign patients after they are discharged.

In France, Germany and Scandinavia, patients must pay in advance.

Official estimates of the cost to the NHS range up to £2billion but some commentators say the true figure is likely to be far higher because there is no proper recording system in place.

Homerton Hospital said it would not be contacting Miss ...................for the payment, despite her assertion that she would pay up if she received a bill.

A spokesman said: “If she wishes to contact us, we would urge her to do so…. But we will not be contacting her.”

He added that Miss ................ received a bill more than six months after she was discharged in 2011, which was returned to the hospital unopened. No further attempts were made to bill her, it is understood.

A spokesman for Homerton University Hospital NHS Foundation Trust added: "We hope the five children have prospered and are healthy. We would be pleased to reopen dialogue with Miss ,,,,,,,,,,,,,, about her outstanding bill."

A Department of Health spokesman said: "It is completely unacceptable that people living outside the UK think they can abuse our NHS. We expect and are supporting the NHS to make every effort to reclaim money owed to it."

Mogbe!!!!!!! This is serious!!!!!!

Op do you mean owes or owns?
