Just wanted to point out that anyone with a Greek AFM and a permanent address in Greece will be able to join a health plan, even if the stay in Greece is temporary (i.e. 3-6 months).
These plans range form the simple basic ones, like the ones required for residence permit purposes, to comprehensive insurance plans offering cover for many thousand of Euros among other covers.
