Disclose everything. yes, even that.
Every Indonesian health policy runs on a legal principle called utmost good faith. You tell the insurer the truth about your health; they price the risk honestly. Break your half of the deal and they get to break theirs — which in practice means your claim is denied at exactly the moment you need the money, and possibly your whole policy is voided.
Here is the part most people get wrong: a pre-existing condition is rarely a dealbreaker. Insurers decline far fewer applicants than the internet suggests. What they actually do, in most cases, is one of three things — exclude the condition, charge you more, or make you wait. All three are better than a denied claim.
What counts as pre-existing?
Broadly: any condition you were diagnosed with, treated for, or had symptoms of before the policy started — whether or not you saw a doctor about it. That covers the obvious (diabetes, hypertension, asthma) and the less obvious (that back pain you mentioned once at a clinic in 2023, the cholesterol reading your last medical check flagged).
The application form asks direct questions. Answer them directly. If a question is ambiguous — "have you ever experienced chest discomfort" is doing a lot of work — disclose and let the underwriter decide. Underwriters are paid to assess risk; you are not paid to assess it for them.
What generally does not count: conditions that develop after the policy starts, and things you could not reasonably have known about. A tumour nobody had found yet is a new condition. A tumour a doctor told you about in writing is a disclosure item, however much you would prefer otherwise.
The three things insurers actually do with what you tell them
When you disclose a condition, the insurer picks from a short menu. Which option you get depends on the condition, how well it is controlled, and the insurer's appetite that year — which is exactly why it pays to compare several insurers rather than accept the first answer.
| Insurer response | What it means | Typical for |
|---|---|---|
| Exclusion rider | The policy covers everything except the named condition and anything caused by it — often permanently, sometimes reviewable after a few claim-free years. | Stable, specific conditions: a repaired knee, treated thyroid issues, mild asthma. |
| Premium loading | Full cover including the condition, at a higher price. The loading is a percentage on top of the standard premium. | Well-controlled hypertension, elevated BMI, managed cholesterol. |
| Waiting period | The condition is covered — but only after a set period, commonly 12 to 24 months for specified illnesses. Every new policy also carries a general waiting period of around 30 days. | Conditions insurers want to see stay quiet: hernias, cataracts, certain tumours. |
| Decline | The insurer passes entirely. Rarer than people fear, and not the end of the road — see below. | Active serious illness, recent major surgery, uncontrolled chronic disease. |
Two insurers can look at the same medical history and give completely different answers. One loads your premium 25 percent; another excludes the condition and charges standard rates. This is normal, and it is the single best argument for getting more than one quote when you have anything to disclose.
Why hiding it never works
The tempting move is obvious: leave the diabetes off the form, get the clean premium, hope for the best. Here is why it fails.
Indonesian insurers do not investigate your health when you apply. They investigate when you claim — and a large hospital claim triggers a records request to every facility you have ever visited. Your BPJS history, your clinic visits, your pharmacy purchases: it is all findable.
The waiting periods exist for the same reason. A 12 to 24 month wait on specified illnesses is the insurer's defence against people who buy a policy the week after a worrying diagnosis. Sit out the wait honestly and the cover is real. Try to game it and you are back in claim-denial territory.
One more practical note: an agent who suggests you "keep the form simple" by leaving something off is optimising for their commission, not your claim. The agent is long gone by the time the claims department opens your file. If anyone advises non-disclosure, that is your cue to find a different agent — and probably a different insurer.
Declined everywhere? BPJS takes you anyway.
BPJS Kesehatan accepts pre-existing conditions with no exclusions. No medical underwriting, no waiting-period fine print on your diabetes, no loading. It is the safety net Indonesia built for exactly this situation, and if private insurers have declined you, it is not a consolation prize — it is the correct move.
- Register, pay the monthly contribution, and your condition is covered through the tiered referral system.
- Pair it with whatever private cover you can get — even a policy that excludes your condition still covers accidents and everything else. Our BPJS vs private guide covers how to combine them without paying twice.
- Foreigners on a KITAS staying six months or more are required to register for BPJS anyway — details in our Bali expat guide.
And conditions change. A declined application at diagnosis is often an accepted one two years later with good control and a clean record. Reapply; browse health plans when you do.
