Here is a paragraph from the "Definitions" in my last Travelex policy. I'm only pasting them so that you can carefully read the actual corresponding clauses in your own policy, and make sure that (perhaps because it's an Annual policy ... ?) there's any important difference. It might be worth calling the company (and waiting in an awful phone-queue) and discussing the "then in effect Annual Policy ... ", if your particular situation is not specifically discussed in the policy.
(It seems unlikely that they would expose themselves to someone who was not insurable upon a policy renewal point, but I've never had an annual policy.)
"Pre-existing Medical Condition” means a condition for which the Insured, Traveling Companion, Family Member,
Business Partner or Host at Destination has, within the period listed in the Schedule and ending on the Insured’s
coverage Policy Effective Date;
(a) Had symptoms which would have prompted a reasonable person to seek medical advice or treatment; or
(b) Received medical advice or treatment; or
(c) Been required to take prescription drugs or medicines, unless the condition for which the drugs or medicines are
taken remains controlled without any change in the required prescription drugs or medicines.
A dependent child born or placed for adoption while this coverage is in force and any condition from which death
ensues will not be considered a Pre-Existing Medical Condition.
And another paragraph:
This rider applies only if this policy is purchased within the Early Purchase Window as listed on the Schedule.
PRE-EXISTING MEDICAL CONDITION EXCLUSION WAIVER
The Company will waive the pre-existing medical condition exclusion, found in Section IV Exclusions and
Limitations, if all of the following conditions are met:
(1) This policy is purchased within the Early Purchase Window;
(2) The amount of coverage purchased equals all prepaid nonrefundable payments or deposits
applicable to the Trip at the time of purchase;
(3) The costs of any subsequent arrangements added to the same Trip are insured within the
timeframe in the Early Purchase Window; and
(4) All Insureds are medically able to travel when the policy is purchased.
Coverage will be limited to the Pre-Existing Medical Condition Exclusion Waiver Maximum Benefit shown in
the Schedule.
