Hospitals write off £112m in foreign patient bills

Though emergency and GP services remain free for everyone, trusts are required to bill for other types of non-urgent treatment for patients who do not ordinarily reside in the UK and charge at 150% of standard NHS rates.

This premium is meant to cover the administrative burden of identifying patients and pursuing payment.

While aimed at tackling "health tourism", the charging system has exemptions for vulnerable groups including asylum seekers and trafficking victims.

But hospitals often struggle to recover costs, particularly when patients return overseas.

Trusts balance their legal obligation to recover costs and the realities of treating patients in need, many of whom have limited means or face other barriers to payment.

Barts Health, serving a large population in east London, wrote off £35m in unpaid bills over the five years - the highest among all responding London trusts.

A spokesperson said: "Where appropriate, we make every effort to recover payment from patients who are liable for the cost of their treatment.

"However, many patients may have limited funds available and some will not be resident in the UK, which means recovering payment can be difficult."

King's College Hospital abandoned £17m, while 10 other trusts each wrote off more than £1m in unrecovered fees.

A spokesperson for King's College Hospital said: "We take seriously our legal obligation to identify patients presenting at our hospitals who are not eligible for free NHS treatment."

The spokesperson added that the trust works "to ensure we embed fairness and proportionality principles into our income recovery processes".

Lewisham and Greenwich Trust, which wrote off £11m, said it would "never deter anyone from seeking treatment, especially as many of these patients are using our maternity services".

A spokesperson emphasised that they "work closely" with patient groups and partners on charging arrangements, "always ensuring we act in an empathetic, compassionate and supportive way towards all patients".

The BMA also maintains that doctors should not have a role in assessing patients' eligibility for free NHS care.

Dr Omar Forge Risk, a campaigner against NHS charging for overseas patients, said the charging system was harmful to public health.

"The reality is that if [patients] were paying back any more, it would push them into destitution," he said.

"Ultimately, if you're charging patients and pushing them more into ill health and into destitution, the costs from any perspective will be greater in the long run."

Government modelling published in 2023 by the then health secretary Jeremy Hunt estimated that more consistent charging of overseas patients could yield an extra £500m per year for the NHS.

However, the true extent of unpaid bills remains unclear, as the £223m invoiced only represents patients identified as chargeable, while many others may receive treatment without ever being billed.

The current government has defended the charging system and said "tens of millions of pounds" were recovered each year.

A DHSC spokesperson added: "Overseas visitors - and those who are not lawfully settled here – should contribute towards their treatment in recognition of the additional cost to the NHS.

"We are committed to getting maximum value for taxpayers' money."
