TL;DR
Getting private medical insurance in the UK with Crohn's is possible, but the condition itself will be excluded. Expert brokers like WeCovr can help you find a policy that covers new, unrelated acute conditions, providing valuable peace of mind.
Key takeaways
- Standard UK PMI does not cover chronic conditions like Crohn's, which require ongoing management.
- Crohn's will be treated as a pre-existing condition, excluded either by a moratorium or a specific clause.
- Expensive biological drugs for Crohn's are not covered under new individual PMI policies.
- A policy is still valuable for covering new, unrelated acute conditions, helping you bypass NHS waiting lists.
- Employer group schemes with 'Medical History Disregarded' underwriting are the main exception and may cover Crohn's.
Navigating the UK private medical insurance market can feel daunting, especially when living with a condition like Crohn's disease. As experienced advisers who have arranged cover for over 900,000 people, the team at WeCovr understands the nuances and challenges you face. This guide provides the clear, authoritative answers you need, explaining exactly how insurers view Crohn's and what you can realistically expect from a policy.
Understanding biological drug exclusions and moratorium underwriting
For anyone with Crohn's disease, two phrases frequently come up when exploring private health insurance: "moratorium underwriting" and "biological drug exclusions". These concepts are central to understanding what a private policy can and cannot do for you.
In simple terms, insurers view Crohn's as a long-term, chronic condition. This is the single most important fact to grasp, as standard UK private medical insurance (PMI) is designed to cover acute conditions – illnesses that are short-lived and curable.
This means that while getting a policy is certainly possible, it will not cover the day-to-day management, consultations, or treatments specifically for your Crohn's disease. This includes high-cost biological drugs like Infliximab or Adalimumab.
Let's break down why this is the case and what your options are.
The Fundamental Rule of UK PMI: Acute vs. Chronic Conditions
Before diving into the specifics of Crohn's, it's vital to understand the core principle of private health insurance in the UK. Policies are built around the distinction between acute and chronic conditions.
- An Acute Condition is a disease, illness, or injury that is likely to respond quickly to treatment and lead to a full recovery. Examples include a broken arm, appendicitis, or a cataract. PMI is designed to provide prompt diagnosis and treatment for these issues.
- A Chronic Condition is an illness that cannot be cured but can be managed through medication and lifestyle changes. It requires long-term monitoring and care. Crohn's disease, diabetes, asthma, and arthritis are all classic examples.
UK private medical insurance does not cover the routine management of chronic conditions. The NHS is, and remains, the primary provider for long-term chronic care in the UK.
A policy is designed to step in when you develop a new acute condition, helping you bypass NHS waiting lists and access private facilities.
| Feature | Acute Condition | Chronic Condition |
|---|---|---|
| Duration | Short-term | Long-term, lifelong |
| Outcome | Curable, full recovery expected | Incurable, requires ongoing management |
| PMI Cover | Covered (if it arises after policy start) | Not Covered (for routine management) |
| Example | Hernia, joint injury, infection | Crohn's Disease, Diabetes, Asthma |
This distinction is why an insurer will not pay for your regular gastroenterologist check-ups or repeat prescriptions for Crohn's medication. However, they would cover you if you needed a hip replacement for an unrelated issue.
How Insurers View Crohn's Disease: Underwriting Explained
Because Crohn's is a pre-existing and chronic condition, insurers must decide how to handle it when you apply for a policy. This is done through a process called underwriting. There are two main types you will encounter.
1. Moratorium Underwriting
This is the most common type of underwriting for individual policies. It's often described as the "wait and see" approach.
- How it works: With a moratorium, the insurer will not cover any medical condition (including Crohn's) that you have had symptoms, treatment, medication, or advice for in the 5 years before your policy starts.
- The "Two-Year Rule": A condition can become eligible for cover if you go for a continuous 2-year period after your policy starts without experiencing any symptoms, needing treatment, or seeking any medical advice for it.
- The Reality for Crohn's: For a condition like Crohn's disease, which requires regular monitoring and management, it is extremely unlikely that you would go for two full years without any form of medical consultation or medication. Therefore, under a moratorium policy, Crohn's disease will effectively be permanently excluded.
This method is quick as you don't need to fill out a detailed medical questionnaire upfront. However, the uncertainty can be a drawback, as eligibility is only determined when you make a claim.
2. Full Medical Underwriting (FMU)
This is the "declare everything upfront" approach.
- How it works: You complete a detailed health questionnaire, disclosing your full medical history, including your Crohn's diagnosis, treatments, and any other conditions. The insurer's underwriting team assesses this information.
- The Likely Outcome: For Crohn's disease, the insurer will almost certainly apply a specific exclusion to your policy. This will be written clearly in your policy documents and will state that Crohn's disease and any related symptoms or conditions are not covered.
- The Benefit of Clarity: While it sounds definitive, FMU provides complete transparency from day one. You know exactly what is and isn't covered, with no grey areas or surprises when you need to make a claim for something else.
Which is better for someone with Crohn's?
| Underwriting Type | Pros | Cons | Best For... |
|---|---|---|---|
| Moratorium | Quicker application process. | Creates uncertainty; claims can be complex. Crohn's is effectively excluded anyway. | Someone with very minor past issues, not a significant chronic condition. |
| Full Medical (FMU) | Provides complete clarity from the start. You know exactly where you stand. | Requires more paperwork upfront. | Recommended for Crohn's. It confirms the exclusion and allows you to focus on the policy's other benefits. |
An expert adviser at WeCovr can walk you through both options and help you decide which underwriting method gives you the most security and peace of mind.
The Big Question: Are Biological Drugs Covered for Crohn's?
This is one of the most common questions we receive, and the answer on a new individual PMI policy is, unfortunately, a clear no.
Biological drugs (biologics) such as Infliximab, Adalimumab, Ustekinumab, and Vedolizumab are groundbreaking treatments that have transformed the management of moderate to severe Crohn's. However, they are not covered by private health insurance for a pre-existing diagnosis for three main reasons:
- They treat a chronic condition: As we've established, PMI is for acute care, not the long-term management of a chronic illness.
- They treat a pre-existing condition: The need for these drugs stems directly from your Crohn's, which existed before you took out the policy.
- They are extremely expensive: The high cost of these specialist drugs makes them commercially unviable for insurers to cover on an individual basis for a known condition.
Care for Crohn's disease, including the prescription and administration of biologics, falls under the remit of the NHS, which follows guidance from the National Institute for Health and Care Excellence (NICE).
So, Is PMI Still Worth It If I Have Crohn's Disease?
Knowing that your Crohn's won't be covered, you might ask: what's the point? This is a valid question, but the answer is that a policy can still be incredibly valuable.
Living with a chronic illness can be stressful enough. The last thing you want is to face a long wait for treatment for a different, painful, or worrying health problem. A private medical insurance policy acts as your safety net for everything else.
With a PMI policy, even with an exclusion for Crohn's, you would still be covered for a wide range of new, acute conditions, such as:
- Orthopaedic Surgery: Fast access to hip replacements, knee surgery, or shoulder repairs.
- Diagnostics: Prompt MRI, CT, and PET scans for new symptoms.
- General Surgery: Hernia repairs, gallbladder removal, appendectomy.
- Cancer Cover: Access to specialist consultants, breakthrough drugs, and treatments not always available on the NHS. This is often a core and highly valued part of any PMI policy.
- Mental Health Support: Many modern policies include extensive mental health pathways, providing therapy and psychiatric support.
- Digital GP Services: 24/7 access to a virtual GP, which is a huge convenience for getting advice on minor ailments without leaving home.
The primary benefit is speed and choice. You get to choose your specialist and hospital, and you can bypass long NHS waiting lists, which in 2026 are still a significant concern for many elective procedures. This allows you to get back to your life, work, and family faster.
The 'Golden Ticket': Employer Group Health Insurance
There is one major exception where cover for Crohn's disease, including biologics, may be possible: a company health insurance scheme.
Larger companies often secure policies with a special type of underwriting called 'Medical History Disregarded' (MHD).
- What is MHD? On an MHD scheme, the insurer agrees to cover all eligible employees (and sometimes their families) regardless of their previous medical history. This means pre-existing conditions are covered.
- Why do insurers offer it? They can offer this on large group schemes because the risk is spread across a big pool of people, most of whom will be healthy.
This is often the only way to get private cover for the ongoing management of Crohn's disease. If your employer offers a group PMI scheme, especially one with MHD underwriting, it is an extremely valuable benefit. We strongly advise checking your employee benefits package or speaking to your HR department to understand the specifics of your company's cover.
Already Have PMI? Switching Insurers with Crohn's
What if you took out a PMI policy when you were healthy and were later diagnosed with Crohn's disease?
In this scenario, your existing policy should cover your initial diagnosis and treatment, as it was a new condition that arose after your policy started. However, once it's deemed chronic, the ongoing management may become limited depending on your policy's terms.
If you then want to switch to a different insurer to find a better price or improved benefits, it is crucial you do so using 'Continued Personal Medical Exclusions' (CPME) underwriting.
- How CPME works: This special underwriting allows you to move to a new insurer while carrying over the terms of your old policy. Essentially, the new insurer agrees to keep covering the conditions you were already covered for, including your newly diagnosed Crohn's. Any exclusions you had on your old policy will also transfer across.
- Why it's important: If you switch on any other terms (like a new moratorium), your Crohn's will be classed as a pre-existing condition and will be excluded.
Insider Tip: Never cancel your existing policy before having a new one with CPME terms fully in place. The process can be complex, and a mistake could lead to you losing your valuable cover for Crohn's. A specialist PMI broker like WeCovr is essential for managing this process seamlessly.
How to Find a strong fit for your needs: A Step-by-Step Guide
- Define Your Priorities: Knowing Crohn's will be excluded, what is most important to you? Is it comprehensive cancer cover? Access to mental health support? A specific hospital list?
- Set Your Budget: You can control the cost of your premium by adjusting your excess (the amount you pay towards a claim), outpatient cover limits, and the network of hospitals you have access to.
- Choose Your Underwriting: As discussed, Full Medical Underwriting (FMU) is often the clearest path for someone with Crohn's, providing certainty from the start.
- Speak to an Expert Broker: This is the most important step. The UK PMI market is complex. A broker's job is to understand your specific situation, compare policies from across the market, and explain the fine print. Their service is free to you, as they are paid a commission by the insurer you choose.
