Is your situation covered?
| Scenario | Typical verdict | Why |
|---|---|---|
| PEC waiver purchased within eligibility window | Usually covered | Typically 14–21 days from initial trip deposit; must insure full trip cost. |
| Stable condition, no changes in look-back period | Depends on wording | Some plans cover 'stable' conditions without a waiver if unchanged 60–180 days. |
| New diagnosis after buying the policy | Usually covered | By definition not pre-existing — normal medical benefits apply. |
| Medication changed inside the look-back window | Usually not | Considered 'not stable' — waiver required to override. |
| Pregnancy — normal | Usually not | Normal pregnancy usually excluded regardless of waiver; complications may be covered. |

The short answer
US travel insurance defines a pre-existing condition as any illness, injury, or symptom that was diagnosed, treated, or would have prompted a reasonable person to seek care during a 'look-back' window (typically 60–180 days) before the effective date. Without a pre-existing condition (PEC) waiver, all claims traceable to that condition are denied — including trip cancellation, interruption, and emergency medical.
The PEC waiver window
Every major insurer offers a free PEC waiver if you meet three conditions: (1) buy the policy within 14–21 days of your first trip payment, (2) insure 100% of prepaid, non-refundable trip cost, and (3) be medically fit to travel on the purchase date. Miss the window and the waiver is off the table for that trip.
- 14–21 day purchase window from first deposit
- Insure the entire prepaid trip cost
- Fit-to-travel at policy purchase
What counts as pre-existing
Any condition treated, tested, medicated, or symptomatic during the look-back window. Includes stable chronic conditions and even routine medication refills for some insurers. 'Stable and controlled' language differs by plan — read the definition, not just the exclusion.
- Diagnosis, treatment, or testing in the look-back window
- New symptoms even without formal diagnosis
- Medication changes (dose, drug, frequency)
- Physician-recommended follow-ups deferred to after the trip
What PolicyPal checks
We identify the look-back window length, waiver eligibility rules, definition of 'stable,' and the medical maximum. We flag whether your specific condition triggers the exclusion and whether the waiver applies. For complex conditions we surface medical-underwriting alternatives (e.g., specialist medical-only expat plans).
Common claim denials
Insurers deny PEC-related claims when the waiver eligibility fails (late purchase, partial trip insured), when medication changed inside the look-back, when a condition is deemed 'not stable' despite a waiver, and when the treating physician's records show earlier symptoms than the patient disclosed.
Frequently asked
- How far back does the look-back period go?
- 60 to 180 days depending on the plan. Comprehensive plans commonly use 60 or 90 days; medical-only plans go longer.
- Does the waiver cost extra?
- Not on most comprehensive plans — it's included if you meet the timing and 'insure full trip cost' rule.
- Is pregnancy pre-existing?
- Normal pregnancy is usually excluded outright. Complications may be covered depending on gestational age and plan wording.
- What if I switch medications for an unrelated condition?
- Any medication change in the look-back window may trigger the exclusion. Document that the change was routine and pre-planned.
- Does the waiver cover Cancel For Any Reason (CFAR)?
- No — CFAR is a separate optional upgrade, usually 40% cash-back and higher premium.
- Can I buy travel insurance after diagnosis?
- Yes, but claims tied to the diagnosis will be denied without a waiver — which usually requires you buy shortly after your first trip deposit, before diagnosis.
