This is a common issue, particularly post-pandemic, due to the backlog in medical consultations and tests. The challenge is for insurers to rate a risk without complete information. Typically, insurers are hesitant to provide cover under such uncertain conditions. However, there is a potential workaround: while insurers may not cover claims related to the undiagnosed condition once it is identified, they can still offer cover for all other declared conditions. This allows individuals to travel, provided they are willing to accept the risk that any claims connected to the undiagnosed condition might not be covered. This scenario forces a choice on whether the potential risk, given the severity and seriousness of the undiagnosed condition, is acceptable for travel. Essentially, while definitive cover for the undiagnosed condition is unlikely, other aspects can still be insured.
