Multilateral regulation In theory, neither the home nor destination country need go it alone in its medical tourism regulatory endeavors. As Nathan Cortez has suggested, countries could formally cooperate in regulating providers and intermediaries and standardizing professional credentials, hospital accreditation, insurance practices, outcomes reporting, and other aspects of the medical tourism trade.56 Such cooperation is also possible as to medical tourism for services illegal in both countries, such as organ tourism, in that police systems could share information on suspectedbuyersandsellerringsacrossborders.Multilateral cooperation on discouraging medical tourism services that are legal in one country but illegal in the other seems less likely, in that the two countries have reached oppositepolicyconclusionsonthepermissibilityoftheservice; even here, though, there may be subsets of the question where there is common ground. For example, the two countries might agree on whether there ought to be price ceilings, or particular informed consent safeguards, or screening processes for surrogacy tourism, even if one country would take the further step of banning commercial surrogacy outright domestically.
