I receive a UK State Pension. I have dual nationality (British/German)and I live in Germany. Am I still entitled to an EHIC card (for use in Germany) Thanks
The official website of the European Commission states that:
To be eligible for a card, you must be insured by or covered by a state social security system in any Member State of the European Union, Iceland, Liechtenstein, Norway or Switzerland
You are thus eligible because you're covered by the British state social security system. This is explained in the FAQ under "What if I'm not working?":
You receive cash benefits because of your activity as an employed or self-employed person. In this case, you will remain subject to the legislation of the country in which you were insured while working.
The EU social security coordination rules are generally applied based on residence, so your nationality does not matter here.
