Navigating private medical insurance can feel complex if you have a pre-existing condition. Many people wonder whether past illnesses or injuries automatically prevent them from getting cover. The good news is that having a pre-existing condition does not automatically rule out private medical insurance.
The UK insurance market offers a range of options for people with prior health issues. Understanding these options helps you make informed decisions about coverage and cost.
Key Takeaways
- Pre-existing conditions do not automatically prevent you from obtaining private medical insurance in the UK.
- Understanding underwriting methods—Moratorium, Full Medical Underwriting, or CPME—is critical to selecting the right plan.
- Honesty, careful comparison, and expert guidance improve your ability to find a policy that meets your needs.
What Counts as a Pre-Existing Condition?
In private medical insurance, a pre‑existing condition is any illness, injury or medical issue for which you’ve had symptoms, received treatment or medication, or sought medical advice in the period before your policy starts. Under moratorium underwriting, insurers typically look back five years and exclude those conditions initially.
Examples include:
- Chronic conditions such as asthma or diabetes
- Joint or musculoskeletal issues requiring physiotherapy
- Heart-related conditions or high blood pressure
- Mental health conditions like anxiety or depression
- Previous cancer diagnoses, including those in remission
If your condition appears in your recent medical records, insurers may classify it as pre-existing. Understanding your underwriting options is key to finding suitable cover.
By contrast, an acute condition is a new, short-term illness or injury that responds quickly to treatment — a broken bone or a sudden infection, for example. PMI is designed primarily to cover acute conditions; pre-existing conditions are treated differently, as explained below.
Understanding Underwriting
Underwriting is the process insurers use to assess health risk and determine the terms of a policy. For those with pre-existing conditions, the type of underwriting determines how, or if, your condition is covered.
Key Underwriting Methods in the UK
| Underwriting Method | How It Works | Suitable For |
| Moratorium (MOR) |
|
People looking for a faster application process without filling detailed medical forms |
| Full Medical Underwriting (FMU) | You complete a detailed health questionnaire. The insurer assesses your history and lists any permanent exclusions from the start. | Individuals seeking clarity about which conditions are and aren’t covered |
| Continued Personal Medical Exclusions (CPME) | For policyholders switching from one insurer to another. Your existing exclusions or terms are carried over to the new policy. | People with pre-existing conditions who want to change provider without losing existing cover |
Which underwriting should I choose?
- Choose MOR if: you want a fast application, no long medical questionnaire, and you’re comfortable that exclusions are assessed at claim time.
- Choose FMU if: you want certainty about exclusions from day one and don’t mind a detailed health declaration.
- Consider CPME if: you already have UK PMI and want to switch without losing existing terms.
How Each Option Works
1. Moratorium Underwriting
Moratorium underwriting is usually the quicker route. The policy automatically excludes any condition you’ve had symptoms, treatment, medication or advice for in the five years before your start date. If you then go two continuous years symptom‑, treatment‑ and advice‑free after the policy starts, that condition may become eligible for cover—but insurers typically confirm this only when you make a claim.
2. Full Medical Underwriting (FMU)
FMU provides clarity from the start. You complete a comprehensive health declaration, and the insurer specifies any permanent exclusions. While some conditions may never be covered, you know precisely which risks are included and excluded.
3. Continued Personal Medical Exclusions (CPME)
CPME is for people already holding private medical insurance. It allows you to switch providers while maintaining the underwriting terms for your pre-existing conditions. This option can help retain coverage while exploring alternative policies.
Practical Steps When Applying with a Pre-Existing Condition
- Be Honest: Disclosing your full medical history is essential. Non-disclosure can invalidate your policy, especially if it’s discovered during a claim.
- Compare Value, Not Just Price: Cheaper policies may offer moratorium terms with exclusions you need to understand. Consider both cost and clarity of cover.
- Don’t Cancel Existing Cover: If you already have a policy, a CPME switch can help you move to a new provider without losing existing cover.
- Consider Expert Advice: Specialist health insurance brokers can:
- Assess your medical history
- Advise on suitable underwriting options
- Present your application to multiple insurers
- Help identify policies that align with your circumstances
Brokers are usually paid by the insurer, so their guidance is often available at no direct cost to you.
Frequently Asked Questions
What does “pre‑existing condition” mean in private medical insurance?
A pre‑existing condition is a health issue you had before your PMI policy started, including any illness you experienced symptoms of, received treatment for, or talked to a GP about before taking out cover.
Can I get private medical insurance if I have pre‑existing conditions?
Yes. You can usually get PMI even with pre‑existing conditions, but the insurer may not cover treatment for those conditions under your policy terms.
Will my pre‑existing condition ever be covered by PMI?
Some policies using moratorium underwriting may cover a pre‑existing condition in the future if you have had no symptoms, treatments, or medical advice for that condition for a continuous period (often around two years).
What types of conditions are typically excluded from PMI cover?
Whether a condition is excluded depends on your underwriting type and history. Under Full Medical Underwriting, insurers typically list any pre-existing condition — such as diabetes, asthma, or arthritis — as a permanent exclusion if you’re still receiving treatment or monitoring for it. Under moratorium underwriting, the same conditions are usually excluded temporarily and may become eligible for cover later if you go a defined period (often two years) without symptoms, treatment, or advice.
Do I need a medical examination to get PMI with pre‑existing conditions?
You normally won’t be asked for a medical exam, but under full medical underwriting, insurers may ask detailed health questions or request medical records to decide which conditions are excluded.
What’s the difference between pre‑existing and acute conditions in PMI?
Acute conditions are new, short‑term health issues expected to respond to treatment (e.g., surgeries or injuries). PMI is designed to cover these. Pre‑existing conditions are past or ongoing health issues that are usually excluded from cover.
Does having a pre‑existing condition always increase my PMI premium?
Not necessarily. In some cases, pre‑existing conditions may not change the cost of cover, but related exclusions will apply. Premiums depend on age, lifestyle, and overall health, as well as underwriting choices.
Can I still use PMI if I’m on an NHS waiting list for treatment?
PMI is designed to cover new, acute conditions arising after your policy starts. Since pre‑existing or planned treatments are typically excluded, being on a waiting list won’t usually mean PMI will cover that treatment. Read our guide What is the solution to the NHS Backlog?
What is moratorium underwriting?
Moratorium underwriting is a method where conditions you’ve had in the last few years are excluded initially, but if you go a defined period without symptoms or treatment, that condition may later be covered.
Is PMI with pre‑existing conditions the same as regular PMI?
If you have pre‑existing conditions, your PMI policy will still function like regular PMI, but it will include specific exclusions or limits related to those conditions. Coverage for new acute illnesses is still possible.
With the right approach, people with pre-existing conditions can access private healthcare that complements NHS services and provides additional flexibility and choice.
