Super visa insurance covers a thyroid condition when it has been stable for the insurer’s stability period: 90 days at Secure Travel to 69, 120 days at TuGo and Destination from 60 to 69, and 180 days at Manulife, GMS, Allianz (from 60) and 21st Century Enhanced in October 2026. Stable means the same levothyroxine or antithyroid dose and no scan, biopsy or referral pending. No wording we checked exempts a thyroid dose adjustment from the definition of a change.
Thyroid disease is among the most common declared conditions for mothers from South Asia, and among the least likely to cause a claim. It causes questionnaire errors because the dose is adjusted after routine blood tests and nobody writes the date down.
What do insurers ask about a thyroid condition?
Most questionnaires do not name the thyroid. They ask whether the parent takes any prescription medication, whether any medication changed in the stability period, and whether any test, scan or referral is pending. Some ask about cancer, which catches a thyroid cancer history.
| Typical question | Why it is asked |
|---|---|
| Taking any prescription medication? | Levothyroxine makes the thyroid a declared condition |
| Any medication started, stopped or dose changed in the stability period? | Tests the stability clause |
| Any test, scan, biopsy or specialist referral pending? | A pending investigation is unstable everywhere |
| Ever diagnosed with cancer? | Thyroid cancer history is assessed under the cancer rules |
A yes to levothyroxine alone rarely changes the premium. A yes to a dose change in the stability period excludes the condition until the period has run. A yes to a pending ultrasound or biopsy excludes it until the result is in.
What does stable mean for a thyroid condition?
Stable means the same drug at the same dose for the whole period, a TSH result the doctor calls unchanged, no new symptom and no pending investigation. A routine TSH test with no change afterwards does not break stability. The dose change that often follows it does.
| Event in the stability period | Stable? |
|---|---|
| Same levothyroxine dose renewed | Yes |
| Switched to an equivalent generic at the same dose | Yes at Manulife, GMS and TuGo |
| Levothyroxine dose increased or decreased | No |
| Routine TSH test, no change in treatment | Yes |
| Ultrasound or biopsy of a nodule ordered, result pending | No |
| Antithyroid drug started, or radioactive iodine planned | No |
| Thyroid surgery done inside the period | No; see recent surgery rules |
| Nodule discharged from follow-up with no plan | Yes |
GMS exempts routine adjustments of warfarin, diabetes, blood pressure and cholesterol medication from its definition of alteration. Thyroid medication is not on that list, so a dose change is an alteration at GMS as elsewhere.
Which insurers cover a stable thyroid condition?
All 8 insurers we compare cover a stable thyroid condition within their stability periods. None applies a thyroid-specific exclusion. The difference between them is only how long the parent must wait after a dose change.
| Insurer (underwriter) | Stability at 65 | Stability at 72 | Days to wait after a dose change at 65 |
|---|---|---|---|
| Secure Travel/RIMI (iA Financial Group; claims by MSH) | 90 days | 180 days | 90 |
| TuGo (iA Financial Group) | 120 days | 180 days | 120, or 7 with the unstable rider to 79 |
| Destination (Zurich, Canadian Branch) | 120 days | 180 days | 120 |
| Allianz (CUMIS General Insurance) | 180 days | 180 days | 180, per PolicyAdvisor |
| Manulife CoverMe Plan B (Manufacturers Life) | 180 days | 180 days | 180 |
| GMS (Group Medical Services) | 180 days | 180 days | 180 |
| 21st Century Enhanced (Manulife) | 180 days | 180 days | 180 |
| Travelance Premier (Old Republic) | 180 days | 180 days | 180 |

What should you document?
Get the prescription with the current dose and the date it was last changed, the most recent TSH result with its date, and the doctor’s letter confirming no change in treatment and no scan or referral pending. If a nodule has been investigated, add the ultrasound or biopsy report and the discharge note.
Keep the completed questionnaire. The THIA Bill of Rights entitles the buyer to a copy of the medical answers before the policy starts. At claim time the insurer compares the home-country file to those answers.
What typically voids a claim?
A thyroid condition rarely causes the claim. The pattern is an unrelated admission, a records request, and a levothyroxine dose change in the stability period that the questionnaire did not declare. The insurer then argues misrepresentation. Under Manulife exclusion 7 or GMS General Condition 8 that can deny the claim, and the policy can be voided from the start.
TuGo adds a $15,000 deductible to any claim where a questionnaire answer at 60 or over was inaccurate. The claims page explains the records request.
Is a no-pre-existing plan safer for a thyroid condition?
Not usually. A no-pre-existing plan excludes any condition the adjuster can link to the thyroid, and the saving over a stable-pre-existing plan is small for a parent with no other condition. If the only reason to consider it is a recent dose change, moving the start date past the stability period is simpler.
The parent’s doctor and the insurer’s policy wording decide whether the condition is stable; this page describes insurer rules, not medical advice. SuperVisaDirect’s advisor can run the questionnaire with the parent on the line by callback, Monday to Friday, 8:00am to 6:00pm ET. If a scan or referral is open, read pending tests and referrals.
Questions people ask
Is hypothyroidism covered by super visa insurance?
Yes, when stable. Hypothyroidism on the same levothyroxine dose for the stability period, with no pending test, is covered by all 8 insurers we compare and rarely affects the premium. The usual error is a dose change after a TSH test that the family considered routine. Any dose change resets the clock.
My mother's levothyroxine dose was adjusted after a blood test. Is that a change?
Yes, at every insurer whose wording we checked. Manulife and GMS exempt routine warfarin and insulin adjustments, and GMS adds blood pressure and cholesterol drugs, but none names thyroid medication. The clock restarts on the date of the new dose. Secure Travel at 90 days to 69 is the shortest wait.
What about a thyroid nodule that is being watched?
A nodule under surveillance with a scan or biopsy pending is unstable until the result is in and no treatment follows. A nodule the doctor has discharged with no follow-up planned is stable. If a biopsy has found cancer, the cancer page applies and the rules are much stricter.
Does Graves' disease or hyperthyroidism change anything?
The same stability test applies: same antithyroid drug at the same dose, no new symptom such as palpitations, and no radioactive iodine or surgery planned. Hyperthyroidism can also trigger a heart rhythm question if it caused atrial fibrillation, and that is a separate condition with its own clock.
