You need to look very carefully about what is included in the policy and what each deductible covers. You may find that there are different deductibles for different types of treatment — some, such as preventative treatments, may not be covered at all in the policy.

Be very careful about the wording, particularly if the policy offers a deductible per event rather than per year. This works to your advantage if, say, you are diagnosed with diabetes. Once you have paid the deductible, you are covered for all future costs relating to the diabetes. But if you are diagnosed with diabetes, hypertension and depression in the same year, you will have to find three deductible payments before you can trigger a claim for each “event”.
