King County Diagnosis Error Attorney
A missed or late diagnosis rarely looks like a single dramatic mistake. More often it is a chest pain sent home without the right test, a scan read too quickly, an abnormal lab result nobody followed up on, or a symptom blamed on stress for months. Injury Law Group NW is a personal injury law firm that investigates diagnostic failures for patients and families across King County and the greater Seattle area, working with qualified medical experts to find out what happened and who is responsible.
If you are searching for a King County diagnosis error attorney, the first thing to know is that a bad outcome alone does not make a case. Doctors cannot guarantee results, and some conditions are genuinely hard to catch. The legal question is whether a reasonably careful provider in the same situation would have reached the right diagnosis sooner, and whether that delay changed what happened to you. That second part, causation, is where most of these cases are won or lost.
Misdiagnosis claims sit on a medical timeline: what the provider knew, when they knew it, what tests were available, and how the disease would have progressed with earlier treatment. Our work is largely about reconstructing that timeline from the records and putting it in front of an insurer, or a jury, in a way that cannot be waved off.
What a Diagnosis Error Claim Actually Requires
Washington medical negligence claims turn on the standard of care. You must show that a provider failed to act as a reasonably prudent provider in the same specialty would have, and that the failure caused you harm. Expert testimony is almost always necessary, which means these cases are expensive to build and hard for an unprepared lawyer to carry.
Causation is the part people underestimate. If a cancer was missed for eight months, we need to show what the delay cost you: a stage progression, a treatment that is no longer an option, a lower chance of survival, or a surgery that became larger than it needed to be. If the same outcome would have occurred with a timely diagnosis, there may be no claim, even if the mistake was real. Part of our job in a first consultation is to tell you honestly which side of that line your situation falls on.
Washington follows a comparative fault rule. If a defendant argues you contributed to the delay, for example by skipping a follow-up appointment, your recovery is reduced by your share of fault rather than eliminated. Defense lawyers lean on this argument often in diagnostic cases, because patient history is easy to characterize after the fact.
Why Choose Injury Law Group NW for a Misdiagnosis Case
Injury Law Group NW is a personal injury firm that represents people hurt by someone else’s negligence throughout King County, Seattle, Bellevue, Issaquah, and the broader Eastside and Puget Sound region. Medical malpractice, including misdiagnosis, delayed diagnosis, and treatment errors, is one of the areas the firm focuses on. Clients pay nothing unless there is a recovery, and the first consultation is free and confidential.
What sets the firm apart in medical cases is where its lawyers learned the work. Troy Hunter, founding partner, spent 16 years in insurance defense litigation, mostly as a partner at Floyd, Pflueger & Ringer, defending insurers and corporate clients against injury and wrongful death claims. David D. Mordekhov spent two decades at Gardner Trabolsi & Mordekhov, a Seattle defense firm, trying wrongful death and catastrophic injury cases before judges and juries across Washington. Warren Barreiro and Hannah Shergold, associate attorneys, round out the team. That defense background matters in diagnostic cases because insurers for hospitals and physician groups have predictable playbooks, and our lawyers have run them from the other side of the table.
Troy Hunter and David Mordekhov are both rated AV Preeminent by Martindale-Hubbell. David has been selected to the Super Lawyers list and teaches trial and deposition skills as faculty at the National Institute for Trial Advocacy. Troy also serves as a dispute mediator. The firm is a member of the Washington State Association for Justice, and its attorneys have argued at every level of the Washington court system, from district court to the Washington Supreme Court. We prepare every claim as though it will be tried, because insurers pay more fairly when they believe the lawyer across from them will actually go to court.
The firm has also recovered more than $1 million for parents whose newborn died after a hospital failed to adequately test for Group B Strep, a case that led the hospital to change its procedures. Past results do not guarantee any future outcome, but that case reflects the kind of testing and diagnostic failure we are willing to take on, and the kind of accountability we look for beyond the check. Clients consistently describe our team as responsive and honest, and our case managers return calls and texts promptly. David is fluent in Russian and Warren speaks Spanish, so families can work with us in their own language.
Common Diagnostic Failures We Investigate
- Delayed cancer diagnosis: Abnormal mammograms, ignored imaging findings, missed biopsy follow-up, and symptoms dismissed over several visits can let a treatable cancer advance to a stage with far worse odds.
- Emergency room misdiagnosis: Heart attack, stroke, aortic dissection, appendicitis, and sepsis are frequently sent home as anxiety, indigestion, or a virus when the right tests were not ordered or were misread.
- Radiology and imaging errors: A fracture, tumor, or bleed that is visible on a scan but overlooked or misreported by the reading physician, or a critical finding that never reaches the treating doctor.
- Lab and pathology mistakes: Mislabeled specimens, misread slides, and test results that were never communicated to the patient or acted on by the ordering provider.
- Birth and prenatal diagnostic failures: Missed infections, untested conditions, and overlooked warning signs in pregnancy or the newborn period, as in the Group B Strep case described above.
- Missed brain injury or spinal conditions: A head injury or cauda equina syndrome sent home without proper imaging, where hours matter and the permanent damage is often the whole case.
- Failure to refer or follow up: A primary care provider who never sends a patient to a specialist, or who does not close the loop on an abnormal result, even though the correct diagnosis was reachable.
- Prescription and medication-related misdiagnosis: Treating the wrong condition with the wrong drug, masking symptoms of the real problem while it worsens.
What to Do If You Suspect a Missed or Late Diagnosis
Start with your own medical care. If you are still being treated, do not stop treatment or confront your provider in a way that disrupts it. Get a second opinion if your condition is active, ideally from a provider in a different practice or hospital system, and ask for copies of every record, imaging study, and lab result you can obtain. You have a right to your records, and requesting them early costs little and protects against gaps later.
Write down what you remember while it is fresh: which symptoms you reported, on which dates, to whom, and what you were told. Keep appointment reminders, patient portal messages, discharge papers, and anything the provider said about test results. Do not post about the situation on social media, and do not sign releases or take calls from a hospital’s risk management office or insurer without speaking to a lawyer first.
Deadlines in Washington medical negligence cases are strict. Under RCW 4.16.350, a malpractice action generally must be filed within three years of the negligent act, or within one year of when you discovered, or reasonably should have discovered, that the injury was caused by the provider, whichever gives you more time. There is also an outer limit of eight years from the act that applies regardless of discovery. A claim involving a foreign body left in a patient has its own one-year clock from actual knowledge. A written, good-faith request for mediation before filing can extend the limitation period by one year under RCW 7.70.110. Wrongful death claims follow a three-year deadline counted from the date of death.
If the provider was a public hospital or a government-run clinic, additional rules apply. Claims against local government entities must be presented on the standard tort claim form to the entity’s designated agent, and a suit generally cannot be filed until 60 days after presentment. Claims against the state follow a similar 60-day rule through the state’s office of risk management. Email and fax are generally not accepted ways of presenting a claim against local government, so how the claim is delivered matters.
Most King County malpractice lawsuits are filed in King County Superior Court, which sits at the King County Courthouse in Seattle and the Maleng Regional Justice Center in Kent. Where your case is heard usually depends on where the claim arose and where the defendants are located. Some cases involving federal facilities, such as a Veterans Affairs hospital, are handled differently and may land in the U.S. District Court for the Western District of Washington in Seattle, so identify the type of provider early.
The most common mistake we see is waiting for certainty. You do not need to know exactly what went wrong before calling a lawyer, and you should not wait until treatment ends. A prompt review lets us preserve records, identify the right specialty of expert, and watch the deadlines for you. If your injuries make travel difficult, we will meet you at home or at the hospital.
How Diagnostic Cases Are Built and Fought
Once we take a case, the first phase is almost entirely records and experts. We gather the full chart, including audit trails, nursing notes, radiology images, and communications, and send them to a physician in the relevant specialty to answer two questions: did the care fall below the standard, and what would timely care have changed. An expert who supports the claim on both points is the foundation. Without one, we do not file.
Hospital and physician insurers defend these cases hard. Expect arguments that the symptoms were nonspecific, that the condition was too rare to expect anyone to catch, that the outcome would have been the same regardless, or that you contributed to the delay. Our lawyers have heard each version from the defense side, which helps us anticipate which records will be used against you and which witnesses will be offered.
Damages in a successful diagnosis case can include past and future medical expenses, lost wages and diminished earning capacity, and compensation for pain, suffering, and loss of enjoyment of life. In a death case, Washington law allows qualifying family members and the estate to seek compensation, including for lost financial support and the loss of the relationship. Parents also have their own cause of action for the injury or death of a child.
Many of these cases resolve in settlement, often after depositions have exposed weaknesses in the defense. Others are tried. We prepare every case with the assumption that a jury will hear it, and we tell clients plainly how we evaluate settlement offers against what a trial might bring.
Questions About Diagnosis Error Claims in King County
What counts as a diagnosis error in a legal sense?
It means a provider failed to diagnose a condition, diagnosed it wrongly, or diagnosed it late, and a reasonably careful provider in the same specialty would have done better. The error must also have caused you harm, such as disease progression, a lost treatment option, or death.
How long do I have to file a misdiagnosis lawsuit in Washington?
Generally three years from the negligent act, or one year from when you discovered or should have discovered the injury, whichever is later. An eight-year outer limit applies in most cases. Because these rules interact, speak with a lawyer as soon as you suspect a problem.
Do I need an expert witness?
Almost always. Washington malpractice claims typically require testimony from a qualified medical professional on the standard of care and causation. Retaining the right expert is one of the first steps we take.
Can I still recover if I was partly responsible, such as missing a follow-up appointment?
Yes. Washington applies comparative fault, so your share of responsibility reduces your recovery but does not bar it. Providers often point to missed appointments or incomplete symptom reports, so we review the record to see what you actually did and what the provider actually knew.
What if the misdiagnosis led to a family member’s death?
The estate’s personal representative can bring a wrongful death claim for the benefit of the spouse or state registered domestic partner and children. If there are none, parents or siblings may qualify. The deadline is generally three years from the date of death.
How much does it cost to hire a diagnosis error attorney?
Your first consultation is free and confidential. We work on a contingency fee basis, so you owe no attorney fee unless we recover money for you.
Is a second opinion enough to prove my doctor was wrong?
No. A second opinion that reaches a different diagnosis is helpful, but it does not show the first doctor breached the standard of care or that the delay harmed you. Those questions require a records review by a qualified expert.
What if the provider was a county, city, or state-run facility?
Special notice rules apply. You must present a formal tort claim before suing, and the lawsuit cannot be filed until 60 days after presentment. Local government claims require delivery by specific methods, and email or fax is generally not accepted, so get legal help early.
Will my health insurance cover treatment while my claim is pending?
Typically, yes. Keep treating and use your health coverage. We help coordinate bills and liens so that care continues while your claim develops, and the at-fault party’s insurer is ultimately responsible for the losses the negligence caused.
My child’s condition was missed. Do the same deadlines apply?
Not always the same way. Washington courts have addressed how tolling rules apply to minors in malpractice cases, and the law here has shifted over the years, so do not assume extra time is available. Parents also have their own claim for a child’s injury or death. Have the facts reviewed promptly so no deadline is lost.
How long does a diagnosis error case take?
These cases typically take longer than an auto crash claim because of expert review, record collection, and defense resistance. Timing varies with the injuries, the number of defendants, and whether the case settles or goes to trial. We will give you a realistic outlook after reviewing your records.
