Asiser is a Spanish healthcare company that provides integrated medical services to both domestic and foreign patients. It operates as a spin-off of the Asisa Group, one of Spain's largest private health insurers. Asiser aims to complement Spain's public and private healthcare systems by offering affordable treatment options without limitations. It facilitates medical tourism through traceable cost control and coordinated care both within and across Spanish hospitals and clinics. Asiser views ethical medical tourism as requiring transparency across providers, protection of patients, and government support for its domestic healthcare system.
