The brochure runs a clean curve. Enrol at 55, renew to 99, no upper age limit. Below it sits another curve, the actuarial one, and that one bends sharply at the first diagnosis.
Underneath every international private medical insurance contract is one of four underwriting models. Most policyholders cannot name which one their carrier uses. They needed to choose it twelve years ago. The renewal letter is where that choice is settled.
The four models, in order of how much they help you later
| Model | Mechanism | Protection at renewal |
|---|---|---|
| Moratorium (MU) | No medical questions; conditions in the prior five years excluded; exclusions lift after 24 continuous symptom-free months | Strongest. A new diagnosis under live cover becomes covered at the next renewal cycle; existing exclusions can lift |
| Full Medical Underwriting (FMU) | Every condition disclosed at application; carrier accepts, excludes, loads, or declines line by line | Mid. Cover continues on existing terms; upgrades re-underwrite; premium re-prices annually |
| Continuing Personal Medical Exclusion (CPME) | New carrier imports the existing exclusion schedule wholesale; no fresh underwriting | Defensive only. Continuity preserved; no exclusion ever lifts; benefit upgrades blocked |
| Medical History Disregarded (MHD) | All conditions covered without disclosure | Best, unavailable to individuals. Corporate group cover only |
The model decides the shape of the renewal letter. Cigna Global, Allianz Care, IMG, William Russell above age thirty-nine, Pacific Cross, APRIL, and Luma default to full medical underwriting for individuals. Bupa Global is the one major carrier whose flagship product is moratorium. William Russell offers moratorium too, capped at age thirty-nine and Bronze or Silver tiers, at a roughly four-percent premium over full underwriting. The structurally superior option is the cheapest one and the one the market most aggressively rations by age.
The twenty-four-month symptom-free clock under moratorium is strict. Allianz Care’s published wording requires no symptoms, no treatment, no medication, no advice taken, and no other indication of the condition through that window. Symptom recurrence resets the clock. A repeat prescription resets the clock. Long-term blood-pressure medication never resets, because it never stops.
What Cigna actually publishes about renewal after diagnosis
The single cleanest articulation of the cliff sits in the carrier’s own framework. Cigna Global publishes four explicit outcomes when a condition is diagnosed under a live policy and a renewal is offered:
| Outcome | What it means in practice |
|---|---|
| Policy renewed unchanged | The diagnosed condition is covered going forward. Premium re-prices by age and portfolio trend; no condition-specific loading |
| Renewed with exclusion | The condition is permanently excluded from cover. Premium re-prices on the unchanged base; the diagnosed condition is now a self-pay item for life |
| Renewed with loading | The condition is covered; the premium carries a condition-specific multiplier on top of the age-band re-pricing |
| Renewal declined | No offer. The policyholder exits the IPMI market with the diagnosis already on their disclosure history |
The carrier does not pre-commit to which lane the policyholder lands in. The Cigna policy rules state that an FMU plan renews annually with no medical questions, unless the policyholder requests a plan change. That last clause is the structural trap. A diabetic at sixty-three who needs to add outpatient cover, raise the inpatient cap, or move to a richer plan tier triggers fresh underwriting at the moment of upgrade, and the diabetes is now on file. The upgrade is rated, restricted, or denied against the post-diagnosis history.
William Russell documents the same shape from a second carrier, framed as three responses to any disclosed pre-existing condition: load the premium, exclude the condition, decline the cover. Two carriers, one model. The same lane menu, by a different name.
The premium loading curve nobody publishes
No IPMI carrier publishes a loading schedule. Pacific Prime documented loading as a practice over a decade ago without numbers; nothing has surfaced since.
The closest public proxy is life-insurance table-ratings. The life industry uses a standard frame: Table 2 adds fifty percent to standard premium, Table 4 adds one hundred percent, Table 8 adds two hundred percent. Underwriters publish typical mappings: a Type 2 diabetic in adequate control lands at Table 2 to 4, atrial fibrillation at Table 4 to 8, cancer in remission at Table 4 to 8 or declined. These are not IPMI rates. They are the actuarial benchmark IPMI rates are built against.
| Diagnosis / outcome | Year 1 after diagnosis | Year 3 after diagnosis | Outcome shape |
|---|---|---|---|
| T2D, accepted with loading (+75%) | $12,600/yr | $15,600/yr | Covered, priced up |
| Atrial fibrillation, loaded (+150%) | $18,000/yr | $22,300/yr | Covered, priced up steeply |
| Cancer remission, exclusion | $8,000/yr | $9,900/yr | Covered for everything except the cancer |
| Cancer or recurrent stroke, declined | — | — | No offer. Exit the IPMI market |
Base premium anchored to a published Cigna Global Senior Plan figure at age 65; trend at Aon 2026 APAC medical 11.3%/yr before any age step-up. Loadings use life-industry Table 2–4 / Table 4–8 mappings as the public proxy. Illustrative, not quotes.
The base premium is anchored to a published Cigna Global Senior Plan benchmark at age sixty-five and uses Aon’s APAC medical trend of 11.3% for 2026 as the per-year compounder before any age step-up. The numbers are illustrative, not quotes. Their direction is the point.
The model also reveals what the brochure curve cannot. There is no policy outcome in which the premium falls. There is no policy outcome in which the disclosed condition stops affecting renewal terms. There is no policy outcome in which the carrier loses optionality.
”Guaranteed renewable to 99” is a promise about the contract, not the price
Pacific Cross publishes its Long Stay Visa plan with renewability to age 99 and a new-entry age limit of eighty. Cigna Global Senior Plan is marketed with no upper age limit. These are real promises about a real thing: the carrier will offer renewal terms.
The terms are the gap. Pacific Cross spells the gap out in its own renewal article: any change in the nature or number of pre-existing conditions between renewals must be declared, so the insurer can adjust the premium. That is the contract working as designed. The renewability promise has been honoured. The price is the variable.
What guaranteed renewability cannot do, at any carrier:
- Cap the renewal premium. Every IPMI carrier reserves the right to re-rate by age band, portfolio medical trend, and condition.
- Prevent an exclusion on a new condition at the point of plan upgrade. The upgrade triggers fresh underwriting.
- Stop the carrier from withdrawing the product from the market and migrating the policyholder to a successor plan with different terms. Legally distinct from non-renewal of the individual.
- Move exclusions between carriers. Only Continuing Personal Medical Exclusion does that, and only by importing the exclusions unchanged.
The brochure is not lying. The brochure is naming one variable and silent on the other.
The three compounding pressures at renewal
The renewal premium increase a sixty-five-year-old policyholder sees is the product of three forces, each independent of the others.
Asia medical trend ran at 11.3% in Aon’s 2026 forecast and 13% in Mercer Marsh Benefits’ 2025 Asia infographic, surveyed across 225 insurers including 77 from Asia, over five times consumer inflation. Aon names the top three medical-cost drivers for 2026 as cardiovascular disease, cancer, and hypertension. They are also the top three diagnoses that trigger the renewal cliff for the individual policyholder. The portfolio trend and the personal trigger are the same conditions.
The age-band step is the smaller of the three. At sixty-five, a policyholder is moving up published age bands every two to five years depending on carrier. The trend and the step compound annually. The loading is one-off but permanent. It carries forward through every subsequent age step and every subsequent trend year.
What the regulator does not reach
The UK Financial Conduct Authority’s General Insurance Pricing Practices rules, in force from January 2022, are the closest thing to a price-walking protection in the personal-insurance market. They apply to UK home and motor insurance only. They do not extend to international private medical insurance.
The carriers writing the SE Asia expat policies are mostly not UK-domiciled. Cigna Global is written from Belgium. Allianz Care and William Russell are underwritten through Allianz’s Irish entity. Pacific Cross is regulated only by the Thai Office of Insurance Commission. A Thailand-resident expat with a Cigna policy cannot use the FCA or the Financial Ombudsman Service as redress.
That is not negligence. It is the structure. The premium re-rates and the exclusion notices that a UK consumer would have a complaints path against, an SE Asia expat does not.
Long-term care is excluded everywhere
The clearest published evidence of the structural ceiling is the Cigna Global Senior Plan’s home-nursing cap at USD 2,500 a year. That is not a typo for a per-day rate. That is the annual cap, against a USD 1,000,000 overall annual benefit ceiling.
Every IPMI policy excludes nursing-home stays, care-home stays, and custodial care through what brokers call the convalescence or non-acute exclusion. No policy in the SE Asia individual market covers a dementia patient’s residential care. No policy covers an assisted-living facility. The Cigna Senior Plan’s $2,500 home-nursing cap is the most generous published figure I found, and it covers roughly one to three weeks of part-time home care at Bangkok or Manila pricing before it runs out.
The renewal letter does not draw attention to this. The renewal letter is about the conditions the policy does cover. The structural ceiling on what it cannot cover stays in the policy wording, untouched.
The exit ramps, ranked by how badly they end
There is no clean exit from a loaded or excluded renewal. Every option is worse than holding the original cover, which is why the original cover keeps re-pricing.
- Switch carriers. Every full-medical-underwriting carrier excludes the new diagnosis on fresh application. Moratorium underwriting at sixty-five is largely closed at major carriers, capped at age thirty-nine at William Russell, restricted at others. Bupa Global is the structural exception and has its own conditions.
- Drop to a regional or local plan. Pacific Cross Expat Care offers a THB 75,000,000 lifetime cap, narrower hospital network, and a 24-month moratorium with a pre-existing-condition sub-benefit capped at THB 200,000 to 300,000 per condition. That is roughly USD 5,500 to 8,200 per condition. A modest cardiac event at Bangkok Hospital exhausts it on day one.
- Continuing Personal Medical Exclusion. Imports the existing exclusion schedule wholesale. No exclusion ever lifts. Plan upgrades blocked.
- Self-insure. Honest only if the diagnosed condition’s expected lifetime cost is bounded. That is exactly when you do not need cover.
- Go bare. The dominant exit, and the one the consular death-abroad statistics for older Western expats absorb. Not a recommendation; an observation.
The IMG Global Medical hard wall illustrates the entry-age problem in the reverse direction: enrol before age sixty-five and stay continuously covered to migrate to the IMG Global Senior Plan at seventy-five. Enrol after sixty-five and the door to lifetime IMG cover is closed. The decision had to be made earlier than the policyholder thought it did.
The decision that has to be made at forty-five
The only mechanism in the market that converts a future diagnosis into covered status without negotiation is moratorium underwriting. It does this by waiting. The twenty-four-month symptom-free, treatment-free, medication-free window is a hard gate, and it is the only gate that opens toward coverage rather than away from it.
The recommendation that follows from the data is not a comfortable one, because it cannot be acted on by the people most likely to need it. Buy moratorium underwriting with a major carrier in your forties, before any diagnosis exists. Lock continuous renewability in. Never let the policy lapse. A lapse converts to a fresh application and the next application is fully underwritten. By sixty-five, with a diagnosis on the disclosure form, every alternative is worse.
The cliff exists because every other option requires the decision to be made after diagnosis. The moratorium policy is the only one that does not.
The brochure curve and the actuarial curve
The IPMI brochure shows a clean line: enrol, renew, stay. The actuarial reality is that the contract holds every option at renewal (accept, exclude, load, deny) and the policyholder holds none. The four-outcome menu is published. Which outcome the policyholder lands in is not. The premium curve under each outcome is also not published, and the public proxy (life-insurance table-ratings) puts the loadings at fifty to two hundred percent on top of an eleven-to-thirteen-percent Asia trend, compounded annually.
The renewal letter is where the brochure becomes the contract. The contract has been honoured. The brochure has been replaced.

Questions
What is the difference between full medical underwriting and moratorium underwriting?
Full Medical Underwriting requires disclosure of every condition at application; the carrier accepts, excludes, loads, or declines on the basis of that disclosure. Moratorium Underwriting asks no medical questions but excludes conditions present in the five years before policy start; those exclusions lift after twenty-four continuous symptom-free, treatment-free, medication-free, advice-free months. Bupa Global is the flagship moratorium carrier; Cigna Global, Allianz Care, IMG, William Russell over 39, and Pacific Cross default to full medical underwriting.
If I am diagnosed with Type 2 diabetes during my policy year, will my premium go up?
Under most full-medical-underwriting policies, the condition is covered going forward and the renewal does not re-underwrite; the carrier instead re-prices the policy by age band and portfolio trend. Asia medical trend ran at 11.3% in 2026 per Aon, before any age step-up. If you request a plan upgrade after the diagnosis, the upgrade is freshly underwritten and the new diagnosis can be excluded or loaded.
Does "guaranteed renewable to 99" mean the premium cannot go up?
No. Pacific Cross publishes renewability to age 99 and Cigna Global states no upper age limit, but every IPMI carrier reserves the right to re-rate by age band, portfolio medical trend, and condition. The guarantee is that the carrier will offer renewal terms, not that the terms will be affordable. Pacific Cross is explicit that any change in pre-existing conditions between renewals triggers a premium adjustment.
Can I switch insurer after a diagnosis to escape a loaded premium?
Switching at 65-plus with a diagnosis usually gets you the same terms or worse. Every full-medical-underwriting carrier will exclude or load the new condition on a fresh application. Continuing Personal Medical Exclusion transfers the existing exclusion list but lifts none of them and prevents benefit upgrades. Moratorium underwriting at 65 is largely closed at the major carriers. William Russell caps moratorium at 39 and Bronze or Silver tiers.
Will any IPMI policy cover nursing home or long-term care?
No. Every IPMI policy excludes long-term care, nursing-home stays, and custodial care through the convalescence or non-acute exclusion. The Cigna Global Senior Plan caps home nursing at USD 2,500 a year, a published number that proves the structural ceiling. Long-term care for an older expat is a self-pay item in every market regardless of policy.
