Can anyone tell me if there are an equiviliant CPT codes in Eurpoe? What happens if a patient has emergency treatment in Europe while traveling? How are the claims coded then?

Various coding modalities are used elsewhere in the world, with probable similarities to the codes used in the U.S. If you are traveling, the provider and the payer probably work that issue out. I have seen ICPCs in Europiean medical news and reference to similar codes for ICD processes. Here's a website you might want to review:

Also Google your questions. Try framing them in various ways.
