Exchange rate
The price of one currency in terms of another at a specific time.
Exchange rates fluctuate continuously. International medical bills may be quoted in USD, EUR, or local currency, with payment in any of these.
What this means for you: lock the FX rate at quote time where possible. Currency moves of 5-10% in 60 days are common — that's real cost.
What a term means for you depends on your own reports. Ask your treating doctor, or send your reports for a free review.
