If you already have diabetes, hypertension, asthma or another diagnosed medical condition, you may wonder:
Can I still get health insurance in Kenya?
The answer is often yes, but the way your existing condition is treated depends on the insurer and medical plan you choose.
A pre-existing medical condition is generally a health condition that existed before your insurance policy started. Insurers may consider conditions for which you had already experienced symptoms, received a diagnosis, sought treatment or taken medication before joining the policy.
Having a pre-existing condition does not automatically mean that you cannot obtain medical insurance. Current Kenyan products demonstrate several approaches: some plans cover pre-existing conditions after a waiting period, some provide them under specific sublimits, and some group arrangements may offer broader treatment. Jubilee’s CoverBora, for example, currently states that pre-existing conditions are covered after a 12-month waiting period, while Britam’s Milele plans use different waiting periods and sublimits depending on the plan selected.
This guide explains how pre-existing conditions affect health insurance in Kenya, what waiting periods and sublimits mean, what you should disclose when applying, and how to compare medical insurance when you or a family member already has a medical condition.
What Is a Pre-Existing Medical Condition?
A pre-existing condition is generally a medical condition that was present before the start of your health insurance policy.
Depending on the insurer’s definition, this can include conditions that:
- Had already been diagnosed
- Had previously been treated
- Were already producing symptoms
- Required medication
- Had previously resulted in hospitalisation
- Had already been investigated by a doctor
Britam’s Milele plan documentation, for example, describes pre-existing conditions in terms of conditions for which a person had sought treatment or experienced relevant symptoms before the insurance commenced.
The exact definition in your own policy matters.
Examples of Pre-Existing Conditions
Common examples may include previously diagnosed:
- Diabetes
- Hypertension
- Asthma
- Heart disease
- Arthritis
- Cancer
- Kidney disease
- Epilepsy
- HIV
- Thyroid conditions
- Chronic back problems
- Previous major surgery
- Other long-term illnesses
This list is not exhaustive.
What matters is whether the condition existed before the insurer accepted you onto the policy.
Are Pre-Existing Conditions Covered by Health Insurance in Kenya?
They can be.
However, coverage varies significantly between products.
An insurer may:
- Cover the condition immediately.
- Cover it after a waiting period.
- Apply a special annual sublimit.
- Require medical underwriting.
- Apply additional conditions.
- Exclude a particular condition.
- Cover the condition differently depending on the plan selected.
For example, Jubilee’s current CoverBora product states that pre-existing conditions are covered after 12 months. Jubilee’s J-Senior also notes that pre-existing conditions may become covered after a waiting period, typically around 12 months.
Britam’s Milele product range likewise treats pre-existing and chronic conditions differently according to the selected plan, using waiting periods and sublimits in some arrangements.
Therefore, never assume:
“This insurer covers pre-existing conditions.”
Instead ask:
“How does this specific policy cover my specific condition?”
What Is a Waiting Period for Pre-Existing Conditions?
A waiting period is the period you must remain insured before a particular benefit becomes available.
For example:
Policy start date: 1 August 2026
Pre-existing condition waiting period: 12 months
The relevant pre-existing-condition benefit may therefore only become available after completing the waiting period, subject to policy terms.
Jubilee currently states in its health-insurance guidance that pre-existing conditions commonly carry waiting periods of around 12 months or more, depending on the product.
Some specific Jubilee products, including CoverBora, currently state a 12-month waiting period for pre-existing conditions.
Waiting periods vary, so always confirm the exact period in writing.
What Is a Sublimit?
A sublimit is a smaller limit that applies to a particular benefit within the overall medical insurance limit.
For example:
Overall inpatient limit
KES 2,000,000
Pre-existing/chronic condition sublimit
KES 150,000
This means the policy may have KES 2 million of general inpatient protection but only KES 150,000 available for eligible treatment associated with specified pre-existing or chronic conditions.
Britam’s current Milele product range uses different sublimits for chronic and pre-existing conditions depending on the selected plan.
This is why the headline inpatient limit alone does not tell you everything about a health insurance policy.
Waiting Period vs Sublimit
These two concepts can apply together.
Consider this hypothetical policy:
Pre-existing condition waiting period: 12 months
Pre-existing condition annual sublimit after waiting period: KES 200,000
During the first 12 months, the condition may not be eligible under that benefit.
After the waiting period ends, eligible treatment may become available, but only up to KES 200,000 per year.
Always check both:
When does cover begin?
and:
How much cover is available?
Does Health Insurance Cover Diabetes?
Some medical insurance products do provide benefits for diabetes.
However, treatment may be classified as:
- Pre-existing if the diagnosis existed before joining
- Newly diagnosed chronic illness if diagnosed after cover began
The distinction can affect waiting periods and benefit limits.
Jubilee’s current waiting-period guidance uses diabetes as an example of a chronic condition that may be subject to waiting periods, while J-Care lists chronic-condition care among its benefits.
If you already have diabetes, ask specifically about:
- Diabetes medication
- Doctor consultations
- Laboratory tests
- Specialist visits
- Hospital admission
- Chronic-condition sublimit
- Waiting period
What About Hypertension?
Hypertension is another common chronic condition.
A person managing hypertension may need:
- Regular blood-pressure reviews
- Long-term medication
- Laboratory monitoring
- Specialist consultations
- Hospital treatment where complications occur
If hypertension existed before joining the insurance plan, it may be treated as a pre-existing condition.
Do not simply ask whether “chronic illnesses” are covered.
Ask how your policy handles:
Pre-existing hypertension.
What About Asthma?
Asthma can require both routine outpatient treatment and emergency hospital care.
Potential costs can include:
- Consultations
- Inhalers
- Medication
- Specialist reviews
- Emergency treatment
- Hospital admission
Jubilee’s current health-insurance material specifically identifies asthma among chronic illnesses that may be covered depending on the plan.
Again, the terms may differ depending on whether the asthma was already diagnosed when you joined.
What About Cancer?
Cancer treatment can be expensive and may involve:
- Diagnostic tests
- Specialist consultations
- Chemotherapy
- Radiotherapy
- Surgery
- Medication
- Hospital admission
Some health plans provide cancer benefits but apply specific waiting periods or limits.
Britam’s Milele plan documentation, for example, currently applies a 12-month waiting period to pre-existing chronic ailments and cancer-related treatment under specified plan arrangements.
Cancer benefits should therefore be compared separately rather than assumed to fall entirely within the headline inpatient limit.
What Happens if the Condition Is Diagnosed After You Buy Insurance?
This is where the difference between:
Pre-existing condition
and:
Newly diagnosed condition
becomes important.
Suppose you purchase health insurance while you have no known diabetes diagnosis.
Eight months later, routine testing reveals diabetes.
Depending on the policy, this may be treated as a newly diagnosed chronic condition, not a pre-existing condition.
Britam’s Milele product currently distinguishes between newly diagnosed chronic conditions and conditions that were pre-existing when the insured joined, with different benefit structures depending on the plan.
The actual treatment depends on the insurer and policy.
Why Do Insurers Ask About Your Medical History?
Health insurance works by assessing and pooling medical risk.
When you apply, insurers may ask about:
- Existing diagnoses
- Previous surgery
- Medication
- Hospital admissions
- Chronic illness
- Ongoing treatment
- Planned procedures
This information allows the insurer to determine the appropriate terms.
Possible outcomes can include:
- Standard acceptance
- Waiting period
- Special sublimit
- Medical examination
- Additional underwriting
- Specific exclusion
The terms should be explained before you accept the policy.
Should You Disclose a Pre-Existing Condition?
Yes.
If the insurance application asks about your medical history, provide accurate information.
Do not hide diabetes, hypertension, previous surgery or another known condition simply because you fear the premium may increase.
Non-disclosure or misrepresentation can create serious problems when you later make a claim.
The insurer may review:
- Medical records
- Previous treatment
- Doctor reports
- Prescription history
- Hospital documentation
when assessing a significant claim.
Accurate disclosure helps ensure that the insurance terms are established correctly from the beginning.
What if You Forget to Mention a Condition?
If you genuinely overlooked relevant information, contact your insurer or insurance intermediary and correct the record.
It is better to clarify the information while the policy is active than to discover the issue during a major claim.
The insurer can then advise whether the condition affects:
- Underwriting
- Benefits
- Waiting periods
- Premium
- Policy terms
Can an Insurer Refuse to Cover a Pre-Existing Condition?
Depending on the product and underwriting rules, an insurer may apply an exclusion or other limitation to a particular condition.
However, this is not the only approach available in the Kenyan market.
Current products show that insurers may instead provide coverage after waiting periods or under specific limits. Jubilee’s health products, for example, include plans where pre-existing conditions are covered after applicable waiting periods, while Britam Milele offers different levels of protection depending on plan structure.
This is why comparing several policies can be valuable for someone with an existing condition.
Can You Get Health Insurance if You Have Multiple Conditions?
Potentially, yes.
However, the insurer may need more detailed underwriting.
For example, someone may already have:
- Diabetes
- Hypertension
- High cholesterol
The insurer could request additional information about:
- Current medication
- Control of the conditions
- Previous complications
- Hospitalisation history
- Age
- Overall health
The terms offered will depend on the particular insurer.
Individual vs Group Medical Insurance
Pre-existing conditions can sometimes be treated differently under group insurance.
For example, Jubilee’s current Care and Health international group arrangement states that qualifying companies with six or more employees can access Medical History Disregarded terms with no waiting periods or exclusions on pre-existing conditions under that particular offering.
This demonstrates an important point:
Individual family insurance and employer/group medical insurance may not use the same underwriting rules.
If your employer provides medical insurance, compare those benefits before purchasing a separate personal plan.
Does Changing Insurance Companies Affect Pre-Existing Conditions?
It can.
Imagine you have been insured continuously for five years and have already completed your previous insurer’s waiting periods.
You then switch to another insurer.
Do not assume the new insurer will automatically recognise everything completed under your old policy.
The new insurer may:
- Recognise continuity
- Require proof of prior cover
- Apply new waiting periods
- Apply different sublimits
- Re-underwrite the condition
Some products specifically allow certain waiting periods to be waived with evidence of previous cover. Jubilee’s current J-Biz group product, for example, states that some waiting periods may be waived with proof of prior coverage.
Before switching insurers, ask:
“Will my completed waiting periods be recognised?”
What Documents Could an Insurer Request?
Depending on the condition and insurer, you may be asked for:
- Medical reports
- Doctor’s notes
- Diagnostic reports
- Current prescriptions
- Previous hospital records
- Medical declaration forms
- Laboratory results
Providing complete information can help the insurer determine the correct terms.
Example: Family With a Pre-Existing Condition
Suppose a family wants medical insurance.
Family members:
Father: 42
Mother: 39
Child: 10
Child: 7
The father already has hypertension.
They receive three hypothetical plans.
| Feature | Plan A | Plan B | Plan C |
|---|---|---|---|
| Annual Premium | KES 65,000 | KES 85,000 | KES 110,000 |
| Inpatient | KES 1M | KES 2M | KES 5M |
| Hypertension | Excluded | Covered after 12 months | Covered under sublimit |
| Outpatient | No | Yes | Yes |
| Chronic Sublimit | None | KES 100K | KES 250K |
Which plan is best?
Looking only at price:
Plan A appears cheapest.
But for a family already managing hypertension, Plan A may provide the least useful protection.
This is why people with existing conditions should compare the specific treatment of the condition, not merely the annual premium.
Questions to Ask Before Buying Health Insurance With a Pre-Existing Condition
Ask your insurance advisor:
- Is my condition covered?
- Is it classified as pre-existing?
- What waiting period applies?
- What happens after the waiting period?
- Is there a specific sublimit?
- Does outpatient treatment qualify?
- Is medication covered?
- Are specialist consultations covered?
- Are laboratory tests covered?
- What happens if hospital admission is required?
- Are complications covered?
- Does the condition affect maternity benefits?
- Will the limit increase after several renewals?
- What happens if I switch insurers?
- What information must I disclose?
These questions are much more useful than simply asking:
“Does this policy cover pre-existing conditions?”
How to Compare Medical Insurance Plans
Create a table like this:
| Feature | Plan A | Plan B | Plan C |
|---|---|---|---|
| Annual Premium | |||
| Inpatient Limit | |||
| Outpatient Limit | |||
| Pre-existing Conditions | |||
| Waiting Period | |||
| Chronic Sublimit | |||
| Medication | |||
| Specialist Visits | |||
| Cancer | |||
| Hospital Network | |||
| Co-pay | |||
| Major Exclusions |
This makes it much easier to identify which policy provides meaningful protection for your actual medical needs.
Common Mistakes to Avoid
Mistake 1: Hiding Your Condition
Disclose relevant medical history accurately.
Mistake 2: Assuming “Covered” Means Immediately Covered
A waiting period may still apply.
Mistake 3: Ignoring Sublimits
A KES 5 million inpatient policy may provide a much smaller limit for your particular condition.
Mistake 4: Looking Only at Premium
A cheaper policy may provide little protection for the condition that matters most to you.
Mistake 5: Switching Insurers Without Checking Continuity
You may unintentionally restart waiting periods.
Mistake 6: Assuming All Chronic Illnesses Are Treated the Same
Different conditions and products can have different terms.
How to Improve Your Chances of Finding Suitable Cover
Compare More Than One Insurer
Different insurance companies have different underwriting approaches.
Provide Complete Medical Information
Accurate information allows the insurer to offer appropriate terms.
Buy Cover Early
Do not wait until your condition deteriorates or major treatment becomes necessary.
Maintain Continuous Insurance
Continuous cover can be important when considering waiting periods and future underwriting.
Review Your Policy Every Year
Your medical needs can change.
Your cover should be reviewed as your family grows older or develops new healthcare requirements.
Verify Your Insurance Provider
Before buying medical insurance, confirm that you are dealing with properly licensed insurance-market participants.
Kenya’s Insurance Regulatory Authority regulates and supervises the insurance industry.
This is especially important when purchasing insurance through:
- Social media
- Online advertisements
- Unfamiliar intermediaries
Always confirm which insurer is underwriting the policy.
Frequently Asked Questions
Can I get medical insurance if I already have diabetes?
Potentially, yes.
Some medical insurance plans provide cover for chronic and pre-existing conditions, but waiting periods, sublimits and other terms may apply. Jubilee’s current health products include chronic-condition protection, while Britam’s Milele range provides different levels of pre-existing/chronic benefits depending on the plan.
How long is the waiting period for pre-existing conditions?
There is no universal period.
Jubilee’s current general guidance says pre-existing-condition waiting periods are commonly around 12 months or more, while specific products such as CoverBora currently use a 12-month period.
Does health insurance cover hypertension?
Some plans may cover hypertension as a chronic or pre-existing condition, subject to applicable waiting periods, limits and policy terms.
Are pre-existing conditions automatically excluded?
No.
Current Kenyan products demonstrate that some plans cover them after waiting periods or under specified limits.
Will my condition be covered immediately?
Not necessarily.
Waiting periods may apply.
What if I develop a chronic illness after joining?
The condition may be treated differently from one that existed before you joined.
Some products distinguish between newly diagnosed and pre-existing chronic conditions.
Should I disclose medication I am currently taking?
If the insurer’s application asks about treatment or medication, provide accurate information.
The Bottom Line
Having a pre-existing medical condition does not automatically mean that you cannot get health insurance in Kenya.
However, you need to understand exactly how the insurer treats your condition.
Check:
Waiting periods
Sublimits
Medication benefits
Outpatient treatment
Hospitalisation
Specialist care
Exclusions
Continuity when changing insurers
The most important question is not:
“Do you cover pre-existing conditions?”
It is:
“How will this policy cover my specific condition, from what date, and up to what limit?”
That answer will help you compare medical insurance far more effectively.
