    4.71,508 Google reviewsRated 4.7 out of 5 on Google from 1508 reviews

    Best for: Diagnosis delays involving birth injuries

    Morgan & Morgan's published results include a $37.8 million Hillsborough County jury award in 2007 after doctors delayed a needed C-section, leaving Brendan Dixon with severe brain injury. That birth-injury result isn't a Seattle misdiagnosis result, but its site also lists misdiagnosis. The firm has an office in the Seattle area and handles medical malpractice alongside other personal injury and employment matters.

    Best for: Older adults with missed diagnoses

    Among Senior Justice Law Firm's published matters, you'll find a hospital lawsuit involving failure to diagnose an abscess. After an Alzheimer's patient's death, the firm obtained a $14 million verdict against a Pennsylvania home health care company that's also included in its results. Although neither matter is identified as a Washington result, the abscess listing also leaves the outcome unstated.

If you're still dealing with treatment, that can matter while you explain a missed diagnosis. Alongside medical malpractice, which the Seattle practice lists, its site includes misdiagnosis and wrongful death.

  6. 6.Settlement or trial

    Many claims settle. Some go to a judge or jury.

Your deadline: 3 years from the treatmentRead the Washington law guide

Each step in more detail

  1. Discuss the diagnosis and dates

    When you speak with the lawyer, explain what was missed and when you learned of the injury. To assess your deadline, a Washington lawyer can consider the 3-year filing rule or the alternative 1-year discovery rule, whichever is later. You can't calculate that deadline from the correct diagnosis alone.

  2. Review the medical record

    Before proceeding, ask how the firm will get medical opinions about the diagnosis delay and review your chart. You don't need a certificate of merit in Washington. In 2009, Putman v. Wenatchee Valley Medical Center struck down the statute that required it.

  3. Consider mediation

    Would a good-faith mediation request fit your situation? Discuss it. Although Washington law gives that request a 1-year deadline extension, don't count on having more time to file. Ask the lawyer how that extension would apply in your case.

  4. File the claim

    Before the firm files the complaint (the document that starts the lawsuit), ask what it needs if it takes your case. Until age 18, Washington pauses the deadline for a child's claim. Have a lawyer apply that rule to the circumstances of your child's case.

  5. Discuss resolution and next steps

    Before hiring, find out how the lawyer would keep you updated and handle settlement or trial. Although Washington doesn't cap medical malpractice damages, that neither promises you'll recover money nor determines how much. You also can't tell from deadline rules how long your case will take.

What a malpractice lawyer costs in Seattle

  1. The first callOften free. Ask before you book.
  2. A written agreementThe share the lawyer takes, set out before work starts.
  3. If you recover moneyThe agreed share and the case costs come out of it.
  4. If the claim failsNo legal fee on a contingency agreement. Ask about costs.
If a claim fails, seven listed firms say there's no lawyer's fee under their contingency arrangements; if it succeeds, the lawyer receives a share of the recovery. A free consultation is offered by every listed firm. Expenses aren't included. Along with court fees, you may have charges for medical records and medical opinions. Before signing, find out whether you'll have to repay those expenses without a recovery and who pays them upfront. Ask what's left for you after expenses, and have the lawyer explain. Because Craig Swapp & Associates' published information doesn't state its contingency arrangement, you'll need to ask the firm directly about those terms.

According to all eight listed firms, you won't pay for the consultation. Contingency fees are also stated by seven.

What to bring to your first call

  • Your medical chart and test reports, along with other records you already have
  • The dates your symptoms began and you saw doctors, plus the date you got the correct diagnosis
  • Who treated you: the doctors' and hospitals' names
  • The diagnosis delay laid out in a brief written timeline
  • Records of other expenses, along with your medical bills
  • Messages or letters you've received from the hospital or insurer
  • Photos, if you think they'd help explain the injury
  • How the injury affects daily life, with notes on your current treatment

Questions to ask a lawyer

  1. 1When this condition was missed, have you handled the resulting claims?
  2. 2When I call, who'll respond, and who'll handle my file?
  3. 3To evaluate my claim, what medical records will you need?
  4. 4For the diagnosis delay, how will you obtain medical opinions?
  5. 5Given my case's dates, what filing deadline do I need to meet?
  6. 6When paying case expenses and your fee, how does it work?
  7. 7If my claim brings no recovery, what could I still owe?
  8. 8How will I get updates if you decide to take my case?

Choosing a misdiagnosis lawyer in Seattle

Don't start with stars; start with the diagnosis. When explaining what happened, tell the lawyer what doctors first thought was wrong and when you got the correct diagnosis. Has the firm handled that condition? Ask. Although a birth-injury verdict or nursing home result may show relevant work, it doesn't establish experience with your particular missed diagnosis.

When reading results, look closely. While Morgan & Morgan lists a delayed C-section verdict, the abscess failure-to-diagnose lawsuit listed by Senior Justice Law Firm gives no outcome. They don't tell you the same thing. Before hiring, ask whether the attorney who handled comparable cases would work on yours, and what happened in those cases. A similar recovery isn't promised by past results.

  • Before the firm decides whether it can take your case, who will review your chart? Ask.
  • Once the initial intake conversation ends, who will answer your calls? Find out.
  • Between your first symptoms and the correct diagnosis, how would the firm investigate what happened? Ask.
  • If Spanish is what you need, find out who'll explain documents and speak with you.

Reviews can reveal patterns in how a firm communicates, but they don't record malpractice outcomes. Several firms on this list get praise for updates; others have mixed feedback about returning calls. Ask who you can contact. Bishop Legal's office is outside Seattle, in Normandy Park, so confirm how you'd meet if travel is difficult.

Although a free consultation lets you discuss whether the firm may take your claim, it isn't an agreement that the firm will represent you. If you recover money under a contingency fee, the lawyer receives a share. You pay no lawyer's fee if the claim fails. Before hiring, ask separately what records and medical opinions cost, including whether you might owe those charges without a recovery.

Questions people ask

How long do I have to file a misdiagnosis claim in Seattle?
You have 3 years from the act or omission under Washington's filing statute, or 1 year from discovering or reasonably being expected to discover that it caused the injury, whichever is later. If you make a good-faith mediation request, you get another 1 year. Have a Washington lawyer check your dates and explain how those rules apply.
Can I speak with a listed lawyer without paying for the consultation?
According to all eight firms on this list, you won't pay for a consultation. Under the contingency arrangements seven describe, the lawyer receives a share of a recovery, with no lawyer's fee if the claim fails. Because case expenses are separate, ask what they involve. Before signing with Craig Swapp & Associates, confirm its contingency terms, which aren't stated in the firm's published information.
Which Seattle firm focuses most closely on medical malpractice?
CMG Law's practice is centered on medical malpractice, and it lists delayed diagnoses and failures to monitor or treat serious conditions. It was founded in 1980 and has a Seattle office. Other listed firms include misdiagnosis within broader practices. Ask about experience with your condition rather than relying on the practice label alone.
What should I do first if I think a diagnosis was missed?
When writing your timeline, include the date you got the correct diagnosis as well as when symptoms began and when you saw doctors. Start gathering records already in your possession. Although every firm on this list offers a free consultation, that first conversation doesn't mean it has accepted your case; contact a Washington lawyer to discuss the filing deadline.
Does Washington require a certificate of merit for a malpractice claim?
No, the certificate of merit statute was struck down in 2009 by Putman v. Wenatchee Valley Medical Center. Although you don't need that certificate, doing without it doesn't establish that a missed diagnosis supports a claim that will succeed. Before proceeding, find out how the firm would get medical opinions about what happened and review your records.
What is the filing rule when the patient is a child?
Until a child turns 18, Washington pauses the filing deadline. The provision treating a parent's knowledge as the child's knowledge was struck down in Schroeder v. Weighall in 2014. Before using the adult deadline, have your child's circumstances checked. To learn what information to gather now and how the rule applies, speak with a Washington lawyer.
What if my loved one died after a delayed diagnosis?
Wrongful death appears among the practice areas or case types of several listed firms. Among those firms are CMG Law and Senior Justice Law Firm. When explaining the diagnosis delay and the death to the lawyer, give the dates of both. Because your family's circumstances matter, ask a Washington lawyer who can bring the claim and which deadline would apply.
How long will a misdiagnosis case take?
Although Washington's filing rules give you deadlines, they don't say how long resolving a case takes. You can't get a reliable timeline for your claim from the firms' published results, either. Before proceeding, ask how the firm would approach settlement or trial and what it needs to assess your records. When the next step changes, how will you hear about it? Find out.
Does Washington limit medical malpractice damages?
Washington doesn't cap medical malpractice damages. Still, a missed diagnosis doesn't always lead to compensation, and a published verdict doesn't predict your result. Morgan & Morgan's delayed C-section verdict, for example, involved a particular injury and case. Ask a Washington lawyer which losses may be considered in your claim.
