San Diego Misdiagnosis Attorney

When a diagnosis comes late or not at all, patients lose the one thing treatment depends on most: time. A tumor that was small enough to treat six months ago. A stroke that could have been stopped before the damage became permanent. An infection that should have been caught during the first hospital visit.

Our team handles misdiagnosis cases involving care provided at Sharp, Scripps, UC San Diego Health, Kaiser, and facilities throughout San Diego County.

What Causes Misdiagnosis in San Diego Hospitals and Clinics

Most misdiagnosis cases are not about one careless doctor. They usually happen when the diagnostic process breaks down. These are the kinds of failures we see again and again in the cases our firm handles.

• Symptoms dismissed as minor because they resemble a more common condition,
• Lab or imaging results that arrive after a patient has been discharged,
• Radiology reads that miss a finding visible on the scan,
• Specimens mislabeled or delayed in pathology,
• Referrals to specialists that never reach the patient,
• Handoffs between providers where critical information gets lost,
• Inadequate screening during routine primary care visits, or
• Physicians who anchor on an initial impression and stop considering alternatives.

Emergency rooms are where these breakdowns happen most often. The pace is fast and patient volume is high, which can limit the time available for a careful evaluation. In busy San Diego ERs like Scripps Mercy Hospital and Sharp Memorial Hospital, that pressure can make it easier for less obvious conditions to be missed.

On a national level, the Agency for Healthcare Research and Quality estimates there are about 7.4 million misdiagnoses in U.S. emergency rooms each year, with roughly 370,000 leading to permanent harm or death.

There are also disparities. Research from Johns Hopkins University found that women and minority patients are more likely to be misdiagnosed, especially with serious conditions like stroke, heart attack, and certain cancers. 

When the diagnosis is wrong, the delay that follows can make treatment harder or less effective. In many cases, that lost time causes the most harm.

Which San Diego Hospitals and Facilities Are Most Often Involved?

Thornsnes Bartolotta McGuire handles misdiagnosis cases arising from care at the major San Diego County hospitals and healthcare providers:

• Scripps Health facilities, including Scripps Mercy in Hillcrest and Chula Vista, Scripps Memorial in La Jolla and Encinitas, and Scripps Green;
• Sharp HealthCare hospitals, including Sharp Memorial, Sharp Grossmont, Sharp Chula Vista, and Sharp Coronado;
• UC San Diego Health, including Jacobs Medical Center and Hillcrest Medical Center;
• Kaiser Permanente San Diego and Zion Medical Centers;
• Rady Children's Hospital for pediatric misdiagnosis cases;
• Tri-City Medical Center and Palomar Medical Center for North County residents; and
• Urgent care centers, imaging facilities, and primary care offices across the region.

Misdiagnosis is not limited to hospital emergency departments. 

A primary care physician who attributes a patient's chest pain to anxiety without ordering cardiac testing. A radiologist at an independent imaging center who misreads an MRI for a referring oncologist. An urgent care provider who sends a patient home with antibiotics for what turns out to be appendicitis. Each of these situations has brought clients to our firm.

Can a Misdiagnosis in San Diego Lead to a Malpractice Claim?

Not every wrong diagnosis is malpractice. Medicine involves uncertainty, and providers make judgment calls under pressure every day. 

A claim is possible when the provider's evaluation fell below what a reasonably careful physician in the same specialty would have done with the same patient and the same information.

California law requires four elements for a medical malpractice claim:

1. A provider-patient relationship existed, creating a duty of care.
2. The provider's actions or inactions fell below the accepted standard of care.
3. That failure caused injury the patient would not have otherwise suffered.
4. The patient sustained measurable damages, such as additional medical costs, lost income, or physical harm.

California's statute of limitations for medical malpractice is one year from the date the injury was discovered or three years from the date of the injury, whichever comes first. Claims involving minors and cases where a provider concealed the error follow different rules. The sooner a patient speaks with a San Diego failure to diagnose attorney, the more our legal team has to work with.

If you or a family member were harmed by a missed, delayed, or wrong diagnosis, our attorneys can review what happened and help you understand your options.

Compensation a Medical Misdiagnosis Attorney in San Diego Can Help You Recover

A misdiagnosis case can address the financial, physical, and personal costs of what the error caused.

Economic damages cover measurable financial losses:

• Past and future medical treatment;
• Corrective procedures, rehabilitation, and medications;
• Home modifications and in-home nursing care;
• Lost wages during recovery;
• Diminished earning capacity when a delayed diagnosis ends a career; and
• Transportation costs for ongoing treatment and specialist visits.

Non-economic damages address the personal toll:

• Physical pain and emotional distress,
• Anxiety, depression, and diminished quality of life,
• Loss of consortium for a spouse or family member, and
• Physical disfigurement or scarring from corrective procedures.

Wrongful death damages are available when a missed diagnosis causes a patient's death. Spouses, children, and certain other family members can recover funeral costs, lost financial support, and compensation for the loss of the relationship.

California's Medical Injury Compensation Reform Act (MICRA) caps non-economic damages at $470,000 for cases not involving wrongful death and $650,000 for wrongful death cases as of 2026. Both caps increase annually until 2033. Economic damages have no cap, and in multi-defendant cases, separate caps may apply against healthcare providers, healthcare institutions, and unaffiliated providers. 

A Martindale-Nolo study found that over 90% of patients who hired an attorney received compensation, compared to roughly 50% of those who handled claims on their own. For misdiagnosis cases, where the medical evidence is technical and the defense is well-resourced, that difference matters.

Settlements and Verdicts in Our Misdiagnosis Cases

$1.2 Million Settlement: Stroke Misdiagnosed as Migraine 

A woman presented with stroke symptoms but was misdiagnosed as having a migraine. She eventually collapsed from a stroke that left her permanently disabled. Her condition was compounded by repeated falls after she was left unattended in the hospital against the treating physician's orders.

$950,000 Settlement: Brain Aneurysm Missed on MRI 

An MRI revealed a brain aneurysm that the treating physician failed to identify. The aneurysm could have been removed eight months before it ruptured had the imaging been read correctly.

How Do You Prove Medical Negligence in a San Diego Misdiagnosis Case?

Proving a misdiagnosis case takes more than showing the doctor got it wrong. It requires reconstructing what the provider knew, what a careful physician would have done with the same information, and what outcome the patient would have had with the correct diagnosis.

Three pieces have to come together:

The Medical Record

Every relevant record is obtained and reviewed, including physician notes, triage records, imaging studies, lab results, pathology reports, consult requests, and electronic ordering logs. What is missing can matter just as much as what is there. No differential diagnosis, canceled test orders, and abnormal results that were never addressed all help show where the process failed.

Expert Review

A qualified medical expert in the same specialty reviews the records and identifies where the provider’s evaluation fell below the standard of care. California law requires this kind of testimony for a claim to move forward. We work with specialists in emergency medicine, radiology, oncology, neurology, and pathology whose credentials hold up in court.

Causation

The error has to be tied directly to the harm. The case has to show what a correct diagnosis would have changed, whether that is an earlier cancer stage, preserved neurological function, or a life saved. That connection is what supports the damages a jury can award.

For example, a patient goes to the ER with chest pain and is diagnosed with acid reflux and sent home. The EKG shows subtle abnormalities, and cardiac enzymes are ordered but not followed up on after discharge. 

Two days later, the patient suffers a major heart attack. In a case like that, the records, expert review, and timeline can show that a proper diagnosis during the first visit would have led to admission and treatment, preventing the more serious outcome.
