Can you buy insurance with a medical history? Pre-existing conditions and cover after cancer

Can you buy insurance with a medical history? What is the difference between "known" and "unknown" pre-existing conditions?

You can apply, but outcomes vary. The key is separating "known" from "unknown" pre-existing conditions: a known condition is one diagnosed, being treated or showing symptoms you were aware of before applying, which must be disclosed and underwritten; an unknown condition is one you were not aware of at the time of applying but which later turns out to have existed already.

Under the Voluntary Health Insurance Scheme (VHIS), certified plans must cover certain pre-existing conditions that were unknown at application, reimbursed on a year-based proportional schedule — generally nothing in the first year, rising year by year. Known pre-existing conditions depend on underwriting: the insurer may add a loading, set a waiting period, or exclude the condition or decline the application. For non-VHIS medical policies, how pre-existing conditions are handled is set by each policy's terms, and many list them as exclusions — read the terms carefully before applying.

Definitions of pre-existing conditions, the proportional schedule and underwriting arrangements are subject to the Health Bureau's latest announcements and individual policy terms.

What underwriting outcomes are possible?

After you disclose your history, underwriting outcomes broadly fall into five types: standard acceptance, a premium loading, an exclusion of a specified condition, postponement and decline. The same condition may get different outcomes from different insurers and products — there is no single answer.

• If you receive a loading or exclusion, you can ask the insurer to state the reason and scope in writing, which makes comparison easier.
• In some cases, once a condition has been stable for a while, you can ask the insurer to review a loading or exclusion; whether this is accepted depends on each company's policy.
• Before approaching several insurers at once, ask a licensed intermediary whether application records may affect other applications.

Underwriting decisions are made by insurers case by case and are subject to the insurer's final decision and policy terms.

What happens if you hide your medical history? Why does honest disclosure matter?

When applying, you must disclose your health honestly — this is the applicant's duty of disclosure. If you hide or leave out a material condition, the insurer may refuse a later claim or even treat the policy as void — so a policy you obtained may not work when you actually need it.

Many people worry that disclosing a history will get them declined, so they "say a bit less". But when handling claims, insurers often check medical records; if they find an undisclosed condition that existed before the application, the consequences are usually worse than an original loading or exclusion. Honest disclosure at least gives you a policy that clearly states what is covered, so you know which parts to fund separately.

• Answer every question on the application form; if you are unsure whether something needs disclosing, disclose it and add an explanation.
• Include past tests, abnormal results, long-term medication and follow-up records — not only confirmed diagnoses.
• Keep a copy of the application form so you can check later what you declared.
• If your health changes between applying and the policy taking effect, notify the insurer as the application documents require.

The duty of disclosure and the consequences of non-disclosure are subject to the policy terms and relevant law.

Applying after cancer or a heart attack: what should you prepare?

Cancer survivors and heart attack survivors can still apply for insurance, but usually need to provide more detailed medical information, and underwriting may take longer. The longer a condition has been stable and the more complete your follow-up records, the easier it is for an insurer to assess the risk; how long you need to wait after recovery depends on the insurer, the product and the condition itself — there is no single standard.

On the product side, VHIS Flexi Plans can raise the sum insured above the Standard Plan, widen the ward class, or add prescribed outpatient and non-surgical cancer treatment cover, at a higher premium; however, if cancer is a known history, that part is still subject to underwriting. As for critical illness insurance, which mainly pays a lump sum on diagnosis, buying cover after cancer or heart disease is generally harder, and common outcomes are an exclusion of related conditions or postponement.

• Doctor's report or discharge summary: stating the diagnosis, treatment and the date treatment ended.
• Recent follow-up and test results: showing whether the condition is currently stable and any sign of recurrence.
• Medication record: current medicines and doses, and any long-term medication.
• How long the condition has been stable: e.g. time since treatment ended and whether you have been readmitted.
• Other relevant history: such as high blood pressure or diabetes, which underwriting usually considers together.

Required documents, underwriting requirements and acceptance vary by insurer and product, and are subject to the insurer's requirements and final decision.

Two years after cancer treatment, how might you plan? Steps to prepare your application

Illustrative case (for explanation only, not a real client): Mrs Chan is 55 and finished cancer treatment two years ago; she attends regular follow-ups and is stable. She is still working with employer group medical cover, but plans to retire in a few years and worries about losing cover when she leaves.

Her approach: first keep and understand her current group cover, including what happens when she leaves; at the same time, gather her oncologist's report, the date treatment ended and recent test results, and ask a licensed intermediary about the underwriting requirements for VHIS and other medical insurance. She understands cancer is a known history, so even if accepted she may face an exclusion of that condition or a loading — so she also sets aside a medical reserve and treats public healthcare as a backstop. To review medical insurance options in later life as well, see our article on medical insurance for seniors. Whatever your situation, the steps to prepare your application are broadly as follows:

1. Step 1: Review existing coverList the scope, limits and exclusions of your group cover, individual medical cover and other policies to find the real gaps. For how to compare, see how to choose medical insurance.
2. Step 2: Organise your medical recordsAsk your doctor for a report and gather your diagnosis, treatment dates, follow-up and test results and medication record, so underwriting has a clear basis.
3. Step 3: Complete the application honestlyAnswer every question on the form honestly, add explanations where unsure, and keep a copy of the application.
4. Step 4: Compare underwriting outcomesIf you receive a loading, exclusion or postponement, check the scope and long-term premiums carefully and weigh whether it is still worthwhile.
5. Step 5: Fill the gaps and review regularlyUse a medical reserve and public healthcare to cover what is not insured; once your condition has been stable for a while, revisit whether a more suitable arrangement is available. For an overall review, see how we can help.

What options are there if you are declined or cover is limited?

Being declined does not mean you are left with nothing. You can work from keeping existing cover, considering simplified-underwriting products, using public healthcare and building a medical reserve, combining them to suit your situation.

• Keep or upgrade existing group cover: group medical cover generally needs no individual underwriting; before leaving a job or retiring, find out whether it can be converted to an individual policy and on what terms.
• Simplified-underwriting products: some insurers offer products with simpler underwriting, but cover is generally more limited, possibly with longer waiting periods or lower benefit limits — read the terms carefully.
• Public healthcare: Hong Kong's public healthcare is heavily subsidised and is an important backstop; private hospital costs can be much higher — see hospital costs in Hong Kong.
• Build a medical reserve: set aside a dedicated fund for uncovered conditions or out-of-pocket costs, managed separately from retirement savings.
• Elderly Health Care Vouchers: Hong Kong residents aged 65 or above receive vouchers each year for private primary care; the amount is as announced by the Health Care Voucher Unit — see medical protection after retirement.
• Disability Allowance is not insurance: if you need support because of a severe disability, look at the government's Disability Allowance — a social security benefit with eligibility assessed by the government, unrelated to commercial insurance.

Eligibility and amounts for government schemes are subject to the relevant departments' latest announcements; insurance product terms are subject to individual policies. Insurance is only one tool, and premium affordability and underwriting outcomes both matter.
