A valid European Insurance Card gives you the right to access state-provided health care. So you are entitled to free medical treatment under the UK’s National Health Service (NHS) nhs.uk
You must also register in Britain with a doctor or General Practitioner and a local dentist.
To get a maximum reimbursement, always choose a practitioner of the NHS.
What happens if the doctor doesn’t accept your “European” card?
You will have to pay and then try to get the reimbursement either from the competent British or Luxembourg institution.
Do you know?
All medical treatment which would not be reimbursed in Luxembourg, won’t be reimbursed when done abroad either (e.g. osteopathy, natural medicine…)
Certain medical treatments like physiotherapy will only be reimbursed after agreement by the Luxembourg health insurance.
