A Guide to Claiming Medical Misdiagnosis Compensation

If your life, or the life of a loved one, has been affected by a misdiagnosis we can help.

The purpose of this guide is to help anyone who has suffered a misdiagnosis and is considering a legal claim for compensation. If you are looking for medical advice, please see the NHS website.

Introduction

In 2014, the NHS paid out £194 million in compensation to 1,302 patients or families for medical conditions that were either not identified or detected too late. Around one in ten of those payouts went to patients whose cancer had been misdiagnosed.

Misdiagnosis is the basis of one of the most common types of clinical and medical negligence compensation claim. Three categories of medical misdiagnosis are identified: total misdiagnosis, incorrect diagnosis and late diagnosis.

Do I have a misdiagnosis claim?

Medical negligence claims differ from personal injury claims as the following will need to be established:

  • there was a breach of duty ("negligence" or "fault"); and
  • the breach of duty was the cause of your injury, damage or loss ("causation" or "avoidable harm").

Breach of Duty

A breach of duty means that the standard of care you received was below the standard that could reasonably be expected of a competent healthcare professional.

Causation

To establish causation, it will need to be demonstrated that the injury you suffered resulted from the negligent care rather than the underlying condition.

Get an impartial opinion

To get impartial advice on whether you have a claim, speak to a misdiagnosis claim expert on 0800 612 7456.

A brief phone consultation will tell you exactly where you stand. There is no obligation to start a claim.

You can also find out if you have a claim with our Online Claim Checker.

Is compensation always payable?

If an error occurred during treatment and the patient was harmed as a result, this may be referred to as an "undesirable outcome".

Not all treatment that results in an undesirable outcome will result in the payment of compensation.

Sometimes an undesirable outcome is due to a known risk associated with the treatment, or due to a mistake that a doctor could reasonably have made in the circumstances.

What if a child was injured?

The 3 year rule does not apply to minors.

A claim can be pursued for anyone under the age of 18 by a parent, guardian or litigation friend. The injured child has up to the age of 21 to start a misdiagnosis claim on their own behalf.

How long do I have to start a claim?

If your injury is apparent immediately after medical treatment, you will have 3 years to start a claim.

It may be that the negligent procedure happened more than 3 years ago, but your injury was only diagnosed recently, within the last 3 years. If so, you may still be able to make a claim.

What if your injury was diagnosed months or years after treatment?

You may not be immediately aware of your injury. In some cases, months and even years can pass before symptoms appear.

The law allows you to make a medical negligence claim up to three years after the 'date of knowledge' (when you first learned of the injury).

It is recommended that you start a claim as soon as possible, as medical negligence cases can be complex. Starting your claim sooner will give your solicitor more time to gather medical evidence, assess the extent of your injury and to negotiate interim payments and your final compensation amount.

Claims for total misdiagnosis

Total or missed misdiagnosis occurs when a medical professional fails to identify the symptoms of a health condition or illness. Without crucial treatment, the condition may develop to a more advanced stage, impacting the patient's treatment, prognosis and recovery time.

Claims for incorrect misdiagnosis

Incorrect diagnosis occurs when a medical professional wrongly diagnoses an illness or condition, which may cause the patient to undergo an unnecessary medical procedure. For example, a patient wrongly diagnosed with cancer may receive needless chemotherapy or have an organ or tissue removed.

Other problems may arise when patients are given the incorrect diagnosis. If their true condition is allowed to progress unchecked, the patient may require more invasive treatment when the condition is eventually uncovered. Some patients may also experience a severe psychological reaction to the mistaken belief that they have a serious illness.

Claims for late diagnosis

Late diagnosis, also known as delayed diagnosis, occurs when opportunities for diagnosis are missed and the medical professional only realises the true nature of an illness or condition when it is at an advanced stage. Mistakes of this kind can increase the pain and discomfort of the patient, prolong the recovery period and in serious cases, reduce the patient's life expectancy.

Why does medical misdiagnosis occur?

Misdiagnosis occurs for a number of reasons, including:

  • Healthcare professionals failing to adequately investigate the symptoms of serious illness
  • Doctors failing to perform the correct tests
  • GP negligence
  • The GP having inadequate expertise with a particular type of healthcare condition
  • Errors by junior medical staff due to a lack of supervision
  • Misinterpretation of test results such as CT scans, MRI scans, X-rays, biopsies, smears and tissue samples.

Compensation awards are calculated by reference to the injuries that are sustained and the impact these injuries have had on a claimant's life, rather than the context or cause of the medical misdiagnosis.

For the purposes of a misdiagnosis claim, however, the reason for the misdiagnosis does matter. It must be shown that the misdiagnosis caused or exacerbated the patient's illness or condition, and that the misdiagnosis itself occurred as a result of the healthcare professional's act or negligence.

Who can make a claim?

Any person who has experienced more pain and suffering than would have been caused by their illness if it had been treated correctly, as a result of a medical professional's misdiagnosis, may be eligible to claim compensation.

Precise time limits are place for making a misdiagnosis compensation claim. A claim must be made within three years of either the date the misdiagnosis occurred, or the date a link is discovered between the misdiagnosis and the patient's injuries or worsening health condition.

Some claimants may experience a significant delay between the time they first see their doctor and the time that the symptoms of the medical misdiagnosis begin to make themselves felt.

Who can you make a misdiagnosis claim against?

Claims are usually brought against a hospital or GP surgery.

For treatment and consultation carried out in an NHS hospital, the defendant is the relevant NHS Trust. In the case of a private consultant, the claim usually is brought against the consultant personally and his or her insurance company.

Is the medical professional liable for a medical misdiagnosis?

To successfully pursue a claim for medical misdiagnosis, the claimant's solicitor will need to establish breach of duty on the part of the healthcare professional, also known as negligence. Negligence occurs when the standard of care received was below the standard that could reasonably be expected of a competent medical professional in the same field.

The claimant's solicitor must also show that the treatment received (or lack of treatment) caused the claimant further injury, pain or suffering. This is known as causation.

While undesirable, not all misdiagnosis claims will result in a payment of compensation. For example, a Court may not award compensation to a patient who received a late diagnosis but whose condition did not get any worse in the intervening period. In this scenario, there is no evidence that an earlier diagnosis would have changed the treatment options or led to a better outcome.

How much compensation can I claim for misdiagnosis?

The amount of money you could claim for your misdiagnosis will depend on:

  • the extent of your injury, and
  • any financial losses or costs you have incurred.

At the start of your claim, your solicitor will consider the many ways your misdiagnosis has affected your life. Your solicitor will take all of these effects into account to calculate the correct compensation award for you.

This calculation will factor in 'general damages' and 'special damages'.

General damages

General damages are awarded for pain, suffering and loss of amenity (PSLA).

Awards for general damages are set by the Judicial College and published in their guidelines for personal injury awards.

Special damages

Special damages are for financial losses and expenses you have incurred as a result of the accident.

What can I claim for after a misdiagnosis? (see list)

Examples of special damages (losses you can claim for) include:

  • Lost earnings (including future earnings)
  • Medical treatment costs
  • Physiotherapy
  • Travel costs
  • Costs of care
  • Costs of adapting your home or car

What is the average injury compensation for a misdiagnosis claim?

The Judicial College injury tables give a approximate idea of the ranges awarded for different injuries.

However, the money you would receive following a misdiagnosis will depend entirely on your specific circumstances.

Your misdiagnosis compensation will be calculated based on the unique impact your injuries have had on your life, your ability to work, and the actual financial losses you have incurred as a result of your injuries.

See the injury table above for some examples.

Will a clinical negligence claim affect my benefits?

It may. The receipt of a compensation award could affect the calculation of any means-tested benefits. One approach to protecting your benefits, would be to set up a "Personal Injury Trust" or "PI Trust". Read more: Should I set up a personal injury trust?

Misdiagnosis FAQ's

Can I claim for someone else?

Yes. In certain circumstances, it is possible to claim compensation on behalf of another person in the capacity of a 'litigation friend'.

If an injured person is either too young or vulnerable, too injured or otherwise unable to claim on their own behalf, their litigation friend can handle the claim process on behalf of the injured person.

The litigation friend will be responsible for communicating with the solicitors, and for making decisions in respect of the claim.

Read more about claiming on behalf of another person.

How long will my claim take?

The length of time needed to secure compensation can vary considerably.

For example, straightforward car accident claims can settle in a matter of weeks, whereas complex medical negligence cases can take years.

Injury claims can also take longer if it is not clear who is responsible for your injury, or if liability is denied by the defendant.

Taken from average case times, this table sets out approximately how long personal injury claims take to settle:

Personal injury claim type

Estimated claim duration*

Road accident claims

4 to 9 months

Work accident claims

6 to 9 months

Medical negligence claims

12 to 36 months

Industrial disease claims

12 to 18 months

Public place or occupiers’ liability claims

6 to 9 months

MIB claims (uninsured drivers)

3 to 4 months**

CICA claims (criminal assault)

12 to 18 months**

*RTA and other claims processed through the Ministry of Justice portal can settle faster.
**Official Criminal Injuries Compensation Authority (CICA) Government agency and Motor Insurers’ Bureau (MIB) figures.

Read more about how long personal injury claims take.

Will I have to go to court?

Highly unlikely. The vast majority of claims that are settled by Quittance’s solicitor panel are settled out of court.

Only a very small percentage (approx. 5%) of personal injury claims go to court. Generally, only very complex cases, or those where liability cannot be resolved, end up in court.

Cases that do ultimately go to court are held in front of a judge, not a jury.

Read more: Will my injury claim go to court and what if it does?

Will I have to go to a solicitor's office?

No. You will not need visit a solicitor's office. As with most professional services, it is no longer necessary to meet face to face with your solicitor. Personal injury claims are dealt with via email, post and telephone.

Should you need to have a medical, this will be arranged at a medical centre near you or at your GP's surgery.

Can I get an early compensation payment?

If you suffer financial hardship as a result of an injury, you may be able to claim an interim compensation payment.

An interim payment is a partial settlement of your claim which is paid before your claim is concluded. The amount you receive in interim payments would then be deducted from your final compensation settlement or award.
