Can I make a delayed diagnosis claim?

You can make a delayed diagnosis claim if a doctor or consultant failed to identify your condition within a reasonable time, and that delay led to a more serious condition, a worse prognosis, and/or more extensive treatment. This might be mean that there was a delayed referral, a false ‘all clear’, or a failure to review blood tests, scans or other results in time.

A delayed diagnosis is not always a sign of medical negligence. Medical negligence means that care falls below the expected standard, leading to medical harm. If you’re unsure about your treatment, it’s best to discuss what happened with an experienced delayed diagnosis claims solicitor.

You don’t need to be certain you have a claim before you get in touch with us. It’s important to remember also that time limits apply to claims for delayed diagnosis compensation. You should contact a legal professional as soon as you can.

Example of a delayed diagnosis claim

Imagine if you saw your GP about the same symptoms more than once. Each time you went, they told you it was nothing serious, and didn’t book a blood test, scan, or referral to a specialist.

It may be classed as medical negligence if a reasonably competent GP would have arranged those checks. If that delay made your condition worse, you may have grounds to claim.

What compensation can help with

Recovering lost income and covering future care

How much compensation you receive after a delayed diagnosis depends on the level of harm caused to your health, quality of life, and finances. You get two types of compensation: general and special. General damages covers your pain, suffering, and quality of life. Special damages cover financial costs, like any lost income, medical charges, and costs of equipment you might need as a result of your injury.

In serious cases, a delay in spotting the signs of cancer, might mean that a more serious grade of cancer develops. This can lead to a more serious prognosis, and sadly, a reduced life expectancy. You deserve to be compensated for your suffering, and have the practical financial means to access the treatment and support you need.

A successful delayed diagnosis claim may help fund:

Medical treatment and surgery costs
Physiotherapy, rehabilitation, and occupational therapy
Psychological support and counselling
Loss of earnings, including future losses if your injury affects your ability to work
Specialist equipment or home adaptations if your injury has lasting effects
Ongoing care and support needs
Travel and transport costs related to your recovery

Understanding the potential value

Every case is different, so no two settlements are the same. A delay in diagnosing cauda equina syndrome left one of our clients with life-changing injuries and long-term care needs.

Our team secured a six-figure settlement to cover his future care. In serious cases like these, settlements take into account any long-term costs you might have to incur as a result of your injury, like home adaptations, lost earnings and round-the-clock care. In these cases, like in the case of our cauda equina client, the full settlement can be considerably high. Think of compensation as protection for a better quality of life over the short and long term.

Understanding interim payments

In more complicated cases, where the litigation is challenging and negotiations with the other side are lengthy, it can take some time before you are awarded your final settlement for delayed diagnosis compensation.

We understand that your health condition may have significantly deteriorated, and you may benefit from accessing specialist treatment and therapies early. Where possible, we will look to secure interim payments for you, so that you can access funds to cover care or lost income while your case continues – so you receive support when you need it.

FAQs about delayed diagnosis claims

Can I claim for delayed diagnosis?

You can claim compensation for delayed diagnosis, if a delay in diagnosis or receiving treatment has caused you additional harm that could have been avoided. Contact our team to discuss your experience to build your case, showing the delay in treatment you received had a negative effect on your life.

What evidence do I need for a delayed diagnosis claim?

To make a delayed diagnosis claim, your solicitor needs to show that:

A doctor, consultant or other healthcare professional was responsible for your care
They failed to diagnose your condition when a reasonably competent professional would have
In the opinion of an independent medical expert, that delay caused your condition to worsen or caused you further harm

It helps if you can keep:

Notes of your appointments and who you saw
Any letters, referrals or results you were given
Receipts, wage records or other proof of money you have lost or paid out

Your solicitor will gather the rest, including:

Your GP, hospital and clinic records
Appointment notes and referral letters
Test requests, test results and scan results
Discharge and follow-up letters
An independent expert medical opinion
Evidence of how the delay affected your health

Hold on to and keep safe any receipts, wage records or other evidence of financial losses to help your solicitor build your case.

What might lead to a delayed diagnosis?

The following situations often lead to delayed diagnosis compensation claims:

Missing symptoms: Missing key symptoms that would have led to further checks, reviews, or referrals. This includes signs of infection or symptoms that needed urgent hospital review, assessment or treatment
Delayed referrals: Not referring you to a specialist fast enough when your symptoms indicated you needed urgent assessment
Test follow-up: Failing to review blood tests, scans or other results, explain what they mean to you or arrange the next step in your care
False all-clear: Telling you everything was clear when your symptoms or abnormal results needed further investigation
Missed fractures: Missing a fracture after an examination, X-ray or scan. This can also include missed spinal or joint injuries.

How long after a delayed diagnosis can I make a claim?

For most delayed diagnosis claims, you have three years to apply from the date you first became aware the delay may have caused you harm. Exemptions apply to children and people lacking mental capacity.

Contact a delayed diagnosis claims solicitor to find out how the timescale might apply to your case.

How long does a delayed diagnosis claim take?

Serious delayed diagnosis claims can take longer than more straightforward claims. This is because medical negligence claims often need detailed evidence.

Your solicitor will advise you of likely timescales when you get in touch, but please be aware that you may overshoot the three-year timeframe to start a claim.

How do I start a delayed diagnosis claim?

You can start by contacting Fletchers for a free initial assessment. Please share what happened to you, how medical staff treated you, and why you believe there may have been a delayed diagnosis

Do delayed diagnosis claims go to court?

Many claims settle without a final court hearing. However, if the other side disputes liability, there is a higher chance that a judge will decide the case. Fletchers Solicitors take care of court proceedings as part of our service.
