What to declare when buying health insurance
What a “Yes” can mean, which records help, and what to check before sharing an OTP.
“Will a daily medicine or an old test need declaring?”
Answer the questions the insurer actually asks, including medicines, tests and past treatment where requested. A condition that is controlled can still need declaring. A “Yes” gives the insurer information to review; it does not by itself tell you what terms it will offer. Before sharing an OTP or signing to confirm the application, read every answer for every person being insured. Keep the submitted form and the insurer’s written terms. [1] [2] [3]

What happens after a “Yes”?
Suppose a parent takes a blood-pressure tablet daily and feels well. If the form asks about regular medicines, the answer needs to describe that medicine and the requested history. Feeling well does not answer a question about treatment. [1] [3]
The insurer uses the information to assess the application, a process called underwriting. Its terms may differ from the quote you first saw. Optima Secure’s wording, for example, allows an extra premium, a specific waiting period or a permanent exclusion based on the proposal and medical information. It requires specific acceptance of its counter-offer. [2]
Read what the offer changes. An extra premium changes the price; a waiting period delays specified cover; an exclusion leaves the stated condition outside cover. Ask for the exact terms in writing before accepting them. This article helps prepare accurate answers; it cannot predict the offer or decide whether it suits the person being insured. [2] [3]
Follow the question, including the dates it asks about
The Optima Secure proposal used here asks about regular medicines, advised investigations, planned surgery and past hospitalisation. Its follow-up fields ask for diagnoses, dates, medicines and test results. Other forms may ask differently. [1]
If a question says “ever”, do not silently read it as “recently”. If it names a period, use that period. The example policy’s definition of a pre-existing disease looks back 36 months for diagnosis, medical advice or treatment. That definition does not put a three-year limit on every question in the proposal. [1] [2]
Before filling in a parent’s or spouse’s answers, go through the form with them where possible. Use prescriptions, reports and discharge summaries to check the history. [3]
Before you complete the form
Prepare the answers person by person
| If the form asks about | Gather or check | Record clearly |
|---|---|---|
| Regular medicines | Current prescription and relevant treatment history | Medicine, reason and requested dates |
| Tests a doctor advised | Advice, available report and pending appointment | What was advised and whether a result exists |
| A past admission or surgery | Discharge summary and follow-up record | Date, reason and current status |
| A condition now controlled or resolved | Relevant diagnosis and treatment records | The history requested, including current status |
| Existing insurance and earlier claims | Schedules and settlement records | The policies and claim details the form requests |
A missing report needs an explanation, not a guess
If a test is pending, say so: “The doctor advised this test on [date]; it has not yet been done.” If you cannot confirm an old diagnosis or date, explain what you know and what is missing. Do not invent a diagnosis or turn uncertainty into “No” simply to complete a field. [3]
If the field cannot hold the explanation, ask the insurer through its official channel how to record it. Include the proposal reference and keep its response. An insurer’s medical test does not replace your answers to the form. [1] [3]
For a dispute about information already submitted, the next step is a written correction or complaint, not another application filled from memory. Our complaint guide shows the grievance route and a letter you can adapt.
Read the completed form before sharing the OTP
Whether an agent, relative or website enters the answers, check the completed form before authorising submission, signing or paying. Check each proposed member, not just the premium payer. If the OTP confirms the declaration, read that declaration before sharing it. [3]
Keep these together:
A submission checklist
Keep the submitted answers and accepted terms
- The completed proposal and any supplementary medical questionnaire.
- Reports and explanations sent with it, with proof of submission or acknowledgement.
- Written clarifications and any medical interview summary made available to you.
- The insurer’s offer, your acceptance and the issued schedule.
The example declaration requires written notice of health or occupation changes after submission and before acceptance is communicated. Check your own declaration if something changes while the application is being processed. [1]
After issue, compare the schedule with the accepted offer. If an answer is wrong or incomplete, contact the insurer promptly in writing and ask what correction and reassessment are needed. Keep its confirmation; sending a correction request does not itself amend the policy. [2] [3]
What the five-year protection does
After 60 continuous months of health cover, including recognised migration and portability credits, the insurer cannot contest a policy or claim for non-disclosure or misrepresentation, except for established fraud. This protection is called the moratorium. The example wording counts a separate period for an increased portion of cover. [2] [4]
It limits those grounds for dispute; it does not turn excluded expenses into covered ones. Before that period, an omission can also matter without every error being fraud. The policy’s disclosure, fraud, non-disclosure and underwriting provisions must be read together. [2] [4]
Finish with a copy of the answers, supporting explanations and accepted terms that you can find later. A conversation with an intermediary is useful; the submitted record shows what the insurer was told.
