Look-back period explained — the window insurers use to judge pre-existing medical conditions for travel cover, why disclosures matter, and how it interacts with excesses and CFAR.

What is a look-back period in travel insurance?

A look-back period is the span of time — often 60 to 180 days before you buy a policy or before departure — that an insurer reviews for medical treatment, symptoms or changes when deciding whether a condition counts as pre-existing.

If you saw a doctor, changed medication, or had symptoms for a condition inside the look-back window, the insurer may exclude related claims unless you declared the condition and received written acceptance (sometimes for a higher premium). Look-back length and wording vary; some policies use “stable and controlled” tests instead of a simple day count. the exact definition in your policy wording.

Failing to disclose is how claims get denied. Honest screening questions are not optional flavour text. Reading guide: how to read a travel insurance policy. Cover types: travel insurance cover levels.

CFAR helps with cancellation for non-medical reasons; it does not rewrite medical exclusions — what is CFAR. Excesses still apply when claims are paid — excess vs deductible.

If your GP altered a dose last month, bring that detail to the screening even if you feel fine today. “Stable” usually means no change in treatment or symptoms for a stated period — not merely that you went to work. When a specialist appointment sits just outside the look-back window but symptoms began inside it, declare the symptoms; insurers care about the clinical story, not only the calendar invite.

How do you work with a look-back period when buying cover?

List every recent consultation, test and medication change inside the insurer’s window, complete the medical screening truthfully, and keep the confirmation email that shows what was accepted.

Example: you twisted a knee 40 days ago and are still in physiotherapy. A policy with a 60-day look-back may treat the knee as pre-existing; you declare it, pay an uplift or accept an exclusion, and buy knowing what is covered. Buying without disclosure to “keep the premium low” risks a denied claim abroad.
