The Irish government has said it is willing to cover the cost of European Health Insurance Cards (EHIC) for all citizens in NI after a no-deal Brexit.
Tanaiste (Irish deputy PM) Simon Coveney said this would cost up to 4m euros (£3.46m).
He said the cards would be available to everyone in Northern Ireland, not just those who hold an Irish passport.
Mr Coveney was speaking during a visit to Downpatrick on Wednesday.
If the UK leaves with no deal, EHICs issued in the UK will not be valid.

Mr Coveney said this was a “contingency plan” in the event of a no-deal Brexit.
“We want to try to extend those privileges to everybody in Northern Ireland,” he said.
“That is something we would try to progress on the basis of residency in Northern Ireland as opposed to whether you hold a British or Irish passport which, of course, is a sensitive thing linked to people’s background and identity.”
Taoiseach Leo Varadkar previously said he wanted it to be retained post-Brexit for people in Northern Ireland.
The UK is trying to reach agreements with EU governments to extend the reciprocal health care arrangements.
Mr Coveney said the Irish government was working to ensure it could be extended for people in Northern Ireland and added that because they would no longer be resident in the EU, it would “pose challenges”.
He also said it would mean having to pass legislation in the Dail.
“When EU citizens travel across the EU they have health insurance cover,” Mr Coveney said.
“We are working and will ensure that we extend that right to Northern Ireland
“That will involve passing legislation here and it will involve the Irish government if necessary p
