Applying for medical insurance with a health history in Malaysia often leads to strict policy exclusions, higher premiums, or outright rejections. While the national MediAsas scheme widens enrolment access for individuals with managed illnesses, it is designed as a financial buffer against future, unrelated medical emergencies rather than a solution for ongoing treatment costs.
With private medical inflation in Malaysia reaching 15% in recent years and only around 22% of the population holding medical insurance or takaful coverage, millions of Malaysians face a difficult catch-22. Those who have already developed health issues need private hospital protection the most, yet they are the exact group most likely to be locked out by conventional underwriting.
To bridge this protection gap, BNM, MOH, and MOF introduced MediAsas (formerly known as the Base MHIT Plan) under the national RESET Strategy. Following its Klang Valley pilot phase in late July 2026, the scheme is slated for a nationwide rollout in January 2027, offering two standalone tiers: MediAsas Teras and MediAsas Fleksi.
However, prospective applicants must understand a vital distinction upfront: widening eligibility to buy a policy is not the same as covering existing medical conditions. Because MediAsas operates on a sustainable risk-pooling model with starting premiums from around RM60 to RM65 a month, it cannot absorb the guaranteed high claims of pre-existing diseases without causing premiums to surge five to ten times higher. Ultimately, this underscores a core principle of financial planning—securing a medical safety net early while you are healthy remains the most reliable way to avoid underwriting hurdles, permanent exclusions, and claim disputes later in life.
Under the official rules for mediasas pre existing conditions, any illness, injury, or symptom that existed prior to your policy’s start date is strictly excluded from coverage. Because MediAsas is a fully underwritten and individually risk-rated product, every applicant must complete a mandatory health declaration so the insurer or takaful operator (ITO) can assess their insurability.
According to BNM’s pilot framework, a pre-existing condition is defined as any medical condition or injury that you had before the Risk Commencement Date (or prior to the last reinstatement date) matching any of the following criteria:
To set realistic expectations and prevent false hope during claim submission, it is important to distinguish between conditions that are permanently barred from claims and scenarios where an applicant might be conditionally accepted into the scheme:
| Coverage Scenario | How MediAsas Treats the Application | Impact on Future Hospital Claims |
|---|---|---|
| Strictly NOT Covered | Pre-existing symptoms, prior diagnoses, ongoing treatments, and any direct or indirect medical complications arising from them. | 0% covered. Claims related to the pre-existing condition remain permanently excluded unless explicitly accepted in writing by the ITO during underwriting. |
| Conditionally Accepted (With Exclusions) | Applicants with certain stable, well-managed conditions or early-stage illnesses in remission may be approved to join the plan. | Covered for new, unrelated conditions only. Hospitalisation for a new accident or unrelated illness is covered, while the prior condition is carved out. |
| Conditionally Accepted (With Premium Loading) | Applicants who present a moderately elevated health risk based on their medical history or assessment. | Covered subject to higher monthly premiums. The ITO charges an extra percentage on top of the base rate to account for the increased claim risk. |
The 7-year moratorium in MediAsas is a consumer protection rule that prevents insurers from contesting claims over innocent non-disclosure after seven continuous years of coverage. It is not a waiting period that automatically unlocks coverage for known pre-existing illnesses after seven years.
While BNM introduced this “no look-back” clause to give honest policyholders greater peace of mind against retrospective claim investigations, strict legal and medical carve-outs still apply:
A mediasas underwriting medical checkup is not compulsory for every applicant, as healthy individuals generally only need to complete a standard health declaration questionnaire. However, if you declare a past surgery, abnormal symptom, or chronic illness, the insurer or takaful operator can request medical reports or a physical examination to evaluate your insurability.
Because MediAsas is individually underwritten rather than guaranteed-issue, your application goes through a structured assessment before coverage begins:
MediAsas attempts to balance broader social inclusivity with strict financial safeguards for its central risk pool. While BNM has encouraged insurers to open the door to applicants who would ordinarily be rejected by commercial plans, strict boundaries remain on what the policy will actually pay for.
When asking can cancer survivor buy mediasas or seeking mediasas chronic illness coverage, the short answer is that eligible individuals in remission or with well-managed conditions can apply to enrol, but their prior illnesses will remain excluded from claims.
During official briefings ahead of the rollout, BNM and MOH clarified how this expanded eligibility works in practice:
While this initiative expands healthcare access, policyholders must carefully review the mediasas 35 exclusions outlined by BNM, which detail specific medical scenarios that fall outside the protection scope.
Most of these 35 items mirror the standard exclusions found in conventional private medical cards in Malaysia, ensuring that payouts are reserved strictly for unforeseen, medically necessary hospitalisation and surgical procedures. Key categories excluded from reimbursement include:
The underwriting rules behind MediAsas reinforce a fundamental truth about health financing: once a symptom appears or a diagnosis is recorded on your medical file, no medical plan—whether government-standardised or private—will cover that condition without restrictions.
Waiting until a health scare happens to look for coverage often means settling for permanent exclusions, paying steep premium loadings, or undergoing invasive medical checkups just to secure basic protection for other parts of your body. By locking in a medical safety net while you are young and carry a clean bill of health, you ensure that conditions developing later in life are treated as eligible new illnesses rather than excluded pre-existing ones.
At GoBowtie, we believe Malaysians deserve clear, transparent health protection without confusing jargon or hidden catches. Understanding policy fine print early empowers you to build a reliable financial buffer before health issues arise—helping you avoid future underwriting rejections and focus fully on recovery when it matters most.

No. The 7-year “no look-back” moratorium is not a waiting period that unlocks coverage for known pre-existing conditions. Declared pre-existing illnesses and the five categories of Pre-Defined Medical Conditions remain permanently excluded. The 7-year rule only prevents insurers from rejecting claims due to an innocent, unintentional oversight on your initial application form.
Yes, an individual with early-stage cancer in remission who has completed treatment may qualify to enrol in MediAsas, subject to individual underwriting. However, while the policy will cover hospitalisation for new, unrelated illnesses or accidental injuries, any future relapse, metastasis, or complication linked to the prior cancer will be excluded from coverage.
No, a physical medical checkup is not mandatory for every applicant. Healthy individuals typically only need to complete the standard health declaration questionnaire during enrolment. However, if you declare a history of chronic illness, past surgery, or ongoing symptoms, the insurer or takaful operator may request medical reports or require a medical examination to assess your insurability.
Failing to disclose a known health condition can result in your hospital claims being delayed or rejected, or your policy being voided. Even after the 7-year moratorium period has passed, insurers retain the right to deny claims at any time if non-disclosure is found to be fraudulent, deliberate, or reckless.
Although MediAsas was developed by Bank Negara Malaysia, the Ministry of Health, and the Ministry of Finance under the RESET Strategy, it operates on a voluntary risk-pooling principle rather than tax-funded social insurance. According to BNM, fully covering all pre-existing conditions and non-essential treatments would cause monthly premiums to jump by five to ten times, making the plan unaffordable for average Malaysians.
