When planning your medical travel to Spain please do create a checklist of the documents you need to carry. At no point during your journey and treatment in Spain should the documents be a reason for any hindrance. Travel documents that are essential are financial means proof like bank statement, sponsorship letter, treatment payment proof or proof of your government covering the costs, employment documents (as per status) and passport, visa, roundtrip ticket, travel medical insurance, accomodation proof and civil status proof. Please do carry your medical documents as well such as medical reports, letter from the doctor/hospital referring you for treatment, correspondence between the doctor/hospital that referred you and the one where you are going to get treated and test reports.
