Sweden: Healthcare is mostly tax-funded. There is a small fee (for adults between 20-85 ) for each appointment. This fee lies between 150-330 SEK (~15-33 €), depending on which region you’re in. Emergency care is usually about 10 € more (40€), and an ambulance trip double (so ~60€). If you’re admitted to a hospital the fee is 120 SEK/day (in my region). Total fees paid for appointments during a year is capped at 1300 SEK (130 €), after that they’re cost-free.
The above is regarding “necessary” care, so things like cosmetic surgery, vasectomies, etc. you’ll have to pay more.
Access to specialist doctors varies, some you can contact directly (usually private practice), and others you’ll have to first make an appointment with a general practitioner at a health center, then get a referall if they deem it necessary. In my region there’s quite a long wait time for many specialists (I had to wait 6 months for a head MRI), and sometimes you’ll have to travel quite far because the care is only offered in one hospital in the region (My wife had to drive 200 km for a surgery).
