The HSE operates the Cross Border Directive (CBD) in Ireland. Under the terms of the CBD, patients in Ireland can seek to be referred to another EU/EEA country for medical treatment that is available in the public health service in Ireland. The patient may access the overseas service in either the public or private health sector of the country they choose to receive the service in. The patient pays for the treatment and claims reimbursement from the HSE at the cost of that treatment in Ireland or the cost of it abroad, whichever is the lesser. The HSE through the National Contact Point (NCP) provides information for patients on the operation of the CBD. Further information is available here.
