We've got your Medical Misdiagnosis Claim covered

Medical Misdiagnosis Claims

Medical misdiagnosis forms the basis of the largest percentage of medical negligence compensation claims. The annual report from NHS Resolution indicated that there has been an increase in the number of claims owing to delays, cancellations and misdiagnosis reflecting longer waiting lists. The consequences of misdiagnosis can be devastating and can lead to delays in patients receiving the treatment they require.

A medical misdiagnosis can occur if your GP or another health professional provides you with an inaccurate or delayed diagnosis.


Whilst diagnosis may be difficult in some circumstances, a treating clinician has a duty to consider all reasonable causes for your condition and to take steps to exclude or confirm any potential diagnosis. Some conditions may have similar signs or symptoms and in those circumstances a “differential” diagnosis would be appropriate. We have a unique understanding of this area as we’ve had years of experience in dealing with all the different aspects of misdiagnosis claims and medical negligence.




We have handled many different medical misdiagnosis compensation claims, including:



Misdiagnosis can occur in many different forms but some of the most common that we see are:


  • A serious illness is allowed to progress unchecked or without being correctly identified


  • Wrong medication is prescribed due to the misdiagnosis of the condition. This could result in a worsening or prolonging of your ailment


  • Test results are misinterpreted or not properly assessed


  • Inadequate consideration is given to alternative or differential diagnoses


  • Your treatment is delayed because of misdiagnosis so your condition gets worse


  • Misdiagnosis in pregnancy related cases can result in damage to the mother and to the unborn baby particularly in relation to a failure to recognise early signs of infection


  • A failure in diagnosing a fracture

For example, it could be that your fracture was missed during an X-ray or MRI, or that there was a failure in conducting adequate tests and investigations. A fracture misdiagnosis or delayed diagnosis could negatively impact the outcome of your treatment, increase recovery time, and in some circumstances lead to serious complications. Our client was awarded £17,500 by his NHS Trust after they failed to identify a stress fracture.




Cancer misdiagnosis can be detrimental to a person’s wellbeing, particularly if the total misdiagnosis or delayed diagnosis impacts your long-term health or leads to additional medical costs.


This is a specialist claim type that requires dedicated legal expertise. Our solicitors are experts in medical negligence and have handled many cancer misdiagnosis claims successfully. Because of the complex nature of diagnosing a disease such as cancer, misdiagnosis or delayed diagnosis can unfortunately happen.


If there has been a delayed or missed diagnosis, then this can result in cancer progressing with a limitation of the available treatment options. In such cases, we can help to determine when cancer should have been diagnosed and how this affected your outcome to your detriment.




Many common conditions can be diagnosed incorrectly. This is because the symptoms of cancer and other conditions can mimic the symptoms of different diseases. This is particularly common during initial visits to the GP when symptoms are in their early stages. These conditions can include but are not limited to:


  • Pancreatic cancer misdiagnosed as gallstones


  • Ovarian cancer misdiagnosed as cysts


  • Lymphoma misdiagnosed as various other illnesses



  • Skeletal injury being treated as muscular pain

Medical Negligence solicitor, Rebecca Dawson, recently settled a serious degenerative spinal injury misdiagnosis case.


The client, who suffered many years of incontinence and leg spasms, was told by his local NHS Trust that his symptoms were inconclusive, and that he wouldn’t be given an MRI because the neurologist believed he had restless leg syndrome.


But for the persistence of Rebecca and her team, the client would now be entirely wheelchair dependent. Despite the Trust failing to admit negligence, overwhelming medical evidence seen at a hearing meant that over £1 million, as part of a misdiagnosis compensation package, was awarded.


In January 2008, another client was diagnosed with progressive transformation of germinal centres (“PTGC”).


On second viewing, there had been a negligent failure to correctly diagnose and treat our client, causing injury and loss. Treatment was not given in 2008, and the disease transformed into an aggressive B-cell Non-Hodgkin’s Lymphoma.


“If our client had been correctly diagnosed with nodular lymphocyte predominant Hodgkin’s lymphoma in 2008, he would have been treated with involved field radiotherapy, possibly with the addition of two cycles of chemotherapy.”

“I have been extremely happy with my solicitor dealing with my case. Right from the outset I have felt that he understood how upset I was and the traumatic experience I had gone through.” 


Mrs. Angela Jane Passey


“I feel very understood and very helped. I feel there has been no judgments towards me. They always emailed me back quickly and professionally. I find the services very helpful.”


Miss Jamie-Leigh Mackintosh


“Amy was so helpful and understanding, she kept me informed and included me in all the decisions. It has been easy and effortless; I feel I have been looked after and a brilliant outcome. I would definitely recommend your company.”

As solicitors specialising in medical misdiagnosis, we understand the difficulties you’re facing. If you have suffered a misdiagnosis, your current condition may worsen because you have not received the treatment or correct advice when you needed it.

    Robert's Story

    "You couldn’t ask for a better team"

    After his symptoms were misdiagnosed, Robert suffered a stroke affecting the left side of his body. He was in hospital for five weeks and had to attend physiotherapy for six months as part of his recovery.

    Our team secured a substantial compensation, which took into consideration the physical and mental impact of Robert’s misdiagnosis on him and his family.

    This enabled Robert’s wife to give up work as well as buy a bungalow together, making it easier for Robert, with his mobility problems. Robert is looking forward to going back to the music concerts and car shows he used to enjoy, as well as spending more time with family.
