Condition said not to be covered
The insurer accepts that you are ill but says the diagnosed condition is not one of the illnesses listed under the policy.
Critical illness claim disputes
Critical Illness Claim Rejected?
A serious diagnosis does not always result in a critical illness payout. Insurers may dispute whether the condition meets the policy's exact definition, whether the required severity has been established, or whether medical or application information affects the claim. We review the policy, medical evidence and insurer's reasoning before identifying the strongest realistic next step.

Why critical illness claims become disputed
Being Seriously Ill Is Not Always the Same as Meeting the Policy Definition
Critical illness policies usually pay only when a listed condition meets the wording and medical criteria set out in the contract. The useful question is therefore not simply how serious the illness is, but whether the insurer has applied the policy definition correctly to the evidence.
Severity threshold not met
A heart attack, cancer, stroke or other listed condition is accepted medically but is said not to satisfy the policy's required level of severity.
Medical evidence interpreted differently
The insurer's medical assessment and your specialist evidence differ about the diagnosis, test results, permanence or impact of the condition.
Non-disclosure or misrepresentation alleged
The insurer says medical, lifestyle or other information was answered incorrectly or incompletely when the policy was taken out.
Total or permanent disability disputed
Where disability benefit forms part of the cover, the dispute may concern occupation, permanence, treatment options or the policy's disability test.
Claim taking too long
Further medical information is repeatedly requested or the insurer remains unable to reach a decision despite having substantial evidence.
What IDS reviews
The Policy Definition and the Medical Evidence Need to Be Read Together
A critical illness claim can turn on precise medical wording. We focus on the parts of the policy and clinical evidence that actually determine whether the insurer's decision is supportable.
The exact insured definition
We identify the wording that has to be satisfied, including any diagnosis, severity, treatment, test-result or permanence requirement.
Specialist medical evidence
Consultant reports, hospital records, diagnostic tests and other clinical evidence are compared directly with the policy definition and insurer's reasoning.
Application and disclosure evidence
If the insurer raises non-disclosure, we examine the questions asked, answers given and evidence showing what the insurer says it would have done differently.
The decision and any medical review
We look at whether the insurer has explained why the evidence does not meet the policy definition and whether relevant specialist evidence has been properly addressed.
Financial Ombudsman approach
What Does the Financial Ombudsman Look At?
The Financial Ombudsman says it looks carefully at the type of critical illness policy, the circumstances of the claim and evidence from both sides, including medical evidence. It also considers whether the insurer has been clear about what the policy does and does not cover.
Where the dispute concerns whether a listed illness has been established, specialist consultant evidence can be particularly important because the issue is whether the medical evidence satisfies the policy's definition - not simply whether the claimant has been seriously unwell.

How we approach the dispute
From Rejected Claim to a Focused Evidence-Led Challenge
The objective is not to argue that the illness is serious enough in general terms. It is to identify the contractual and medical issue the insurer relies upon and test that position against the evidence.
Identify the definition in dispute
We isolate the exact policy wording, severity threshold, disability test or disclosure issue on which the insurer's decision depends.
Match the evidence to the wording
Medical reports, tests and other relevant evidence are organised around the specific points that have to be established.
Escalate where appropriate
The next step may involve focused correspondence, a formal complaint, FOS where eligible, or more formal litigation and barrister support in suitable cases.

Common questions
Critical Illness Claim Dispute FAQs
Can I challenge a critical illness claim if my insurer says my condition is not severe enough?
Potentially, but the outcome depends on the policy's precise definition and the medical evidence. Some conditions are only covered when specified diagnostic or severity criteria are met, so the insurer's reasoning should be compared carefully with the relevant specialist evidence.
What if my consultant says I have the condition but the insurer still refuses to pay?
The diagnosis alone may not settle the dispute if the policy includes additional severity, test-result or permanence requirements. The useful question is whether the consultant's evidence addresses each part of the insured definition and whether the insurer has explained any remaining shortfall.
What if the insurer says I failed to disclose medical information?
The application questions, answers, medical history and underwriting evidence should be examined together. You can also read our separate support for non-disclosure and misrepresentation disputes.
Is the initial review free?
Yes. The initial review is free and there is no obligation to proceed. If further work appears appropriate, the proposed scope and pricing can be explained before you decide what to do next.
