The end of non-urgent free care will see trusts recover the costs of looking after people who are not resident in the UK.
Hospital staff have been told to ask patients for utility bills, bank statements and proof of employment so they pay upfront for treatment.
It means anyone seeking non-urgent care will have to prove they are resident in the UK.
The drive is being introduced because an estimated £2billion is lost each year to health tourists.
There have been shocking examples of migrants failing to purchase health insurance when Travelling to the UK because they know they can access free care while here.
Health Minister Lord James O’Shaughnessy said: “The NHS is a cherished national institution that is paid for by British taxpayers.
“We have no problem with overseas visitors using our NHS as long as they make a fair financial contribution, just as the British taxpayer does.
The new regulations simply require NHS bodies to make enquiries about, and then charge, those who aren’t entitled to free NHS care.
“All the money raised goes back into funding and improving care for NHS patients.
We are clear that some vulnerable groups are exempt from charging and the NHS will never withhold urgent and immediately necessary treatment.”
A&E treatment and access to GPs will remain free of charge.
Asylum seekers indicating they want to stay in the UK, even if they have arrived here illegally, will also continue to have access to free care as part of a support package provided by the taxpayer.
Charges will be based on whether the patient comes from the European Economic Area or outside.
For in-patient “general medicine”, including Type 2 diabetes and high blood pressure, those within the EEA will be charged £1,439.72 while those outside will be billed £2,159.59.
