Identify the benefit
Deductibles are especially relevant to travel-medical products; they may not apply the same way to every travel-insurance benefit.
Per policy or per event
Read whether the deductible is applied once, per incident or another way.
Compare premium and exposure
A higher deductible can lower premium but increase what you pay before benefits apply.
Do not confuse deductible with limit
The deductible and the policy maximum answer different questions.
