Russia

Everyone has free health insurance that covers all procedures, doctor visits, ambulance calls, and most hospitalization cases in the respective government clinics based on where they live.

General physicians are available at any government clinic as needed, regardless of where you are. Other specialists are only available at your main clinic and directed to either by GP or as part of a free 5-yearly checkup. You can book an appointment online, call into the clinic, or come in person to do so. GPs are always available on short notice, and you can get there without booking if you need urgent care. Dentists are also available without booking for urgent cases. Trauma units operate 24/7 and accept without booking.

If you’re too sick to come in person, you can also call for a GP to arrive through a unified hotline, regardless of your current location, or even whether you have Russian citizenship or insurance for that matter.

The quality of care itself is highly regionally dependent, but mostly alright. Larger cities like Moscow and Saint Petersburg have it better, smaller, faraway cities have it worse. Queues differ significantly between places and specialists, and can be anything between 15 minutes and 2-3 weeks.

Private clinics exist, prices are bitey, but the quality of care is generally high. Work can offer private health insurance, giving free access to their services.

TL;DR all free (with some paid options), available to everyone, decent quality, acceptable waiting times.
