Key Takeaways

• Medical malpractice claims in Washington must be filed within 3 years of the incident or 1 year after discovering the error.
• Exceptions exist for minors and cases involving fraud or intentional concealment.
• Understanding these time limits is crucial for timely legal action.

Can I Sue for Medical Malpractice in Washington?

Yes. If a healthcare provider in Washington State caused you injury through negligent care, you have the right to file a medical malpractice lawsuit. However, several conditions must be met before a claim can proceed.

First, you must be able to show that the healthcare provider owed you a duty of care, which is established by the existence of a doctor-patient relationship. If you were a patient under their care, this element is typically straightforward.

Second, you must demonstrate that the provider breached the standard of care. This means their treatment fell below what a reasonably competent provider in the same specialty would have done under similar circumstances. Proving a breach of the standard of care almost always requires testimony from a qualified medical expert.

Third, you must show that the provider’s negligence directly caused your injury. A bad outcome alone does not constitute malpractice. Not every surgery with complications, unexpected side effect, or treatment that did not work as hoped rises to the level of negligence. The key question is whether the provider’s actions fell below the accepted standard, and whether that failure caused your harm.

Finally, you must have suffered actual damages, such as additional medical expenses, lost income, physical pain, emotional distress, or diminished quality of life. If all four elements can be established, you may have a valid medical malpractice claim in Washington.

It is important to note that Washington requires a certificate of merit in most medical malpractice cases. Under RCW 7.70.150, the plaintiff must provide a written opinion from a qualified medical expert stating that there is a reasonable basis for the claim before or shortly after filing the lawsuit.

Which Medical Error Best Matches Your Situation?

Different medical malpractice claims require different evidence. Choose the closest situation below to see what may need review.

Misdiagnosis Failure to Treat Informed Consent Surgical or Medication Error Birth Injury Infection or Sanitation

Misdiagnosis claims often depend on timing and missed warning signs.

These cases may involve missed symptoms, delayed testing, failure to refer to a specialist, or a diagnosis that was corrected later by another provider.

• Save test results, imaging, referrals, and follow-up notes.
• Write down when symptoms started and when the correct diagnosis was made.
• Ask whether an expert can identify a breach in the standard of care.

Medical malpractice claims need expert review. Washington cases require thorough medical expert evaluation and testimony to demonstrate a breach in the standard of care.

Washington’s Deadline for Filing Medical Malpractice Claims

In Washington State, the statute of limitations for filing a medical malpractice claim is three years from when the medical error occurred, causing injury or illness. However, if the injury or its cause was not immediately apparent, individuals have one year from the date the injury was discovered or reasonably should have been discovered, to file a claim. This ensures that patients have a fair opportunity to seek justice even if the effects of the malpractice are not immediately evident.

Suffering new or worsening injuries after visiting the doctor is one of the last things you’d expect. However, a 2016 study found that medical errors are the third leading cause of death in the United States. Medical providers have a duty to provide a certain level of care to their patients.

Under Washington’s medical malpractice statute, a medical professional may be held liable if their failure to meet this standard results in a patient’s injury. 

The patient must prove that the physician acted negligently in rendering care and that negligence resulted in injury by establishing four legal elements:

• The medical professional owed a duty to the patient,
• They breached that duty, 
• The injury stemmed from the breach, and
• The patient suffered damages because of the breach. 

However, a critical first inquiry to these cases is whether the case falls within the statute of limitations and statute of repose. 

Washington State Medical Malpractice Statute of Limitations

The statute of limitations refers to the time a person has to file a lawsuit. Those that miss the deadline may not be able to recover any damages for their injuries. Revised Code of Washington (RCW) section 4.16.350 sets the time limit to file a medical malpractice lawsuit. Under the statute, victims must file their case by the later of one of two dates: 

• Three years after the medical negligence that caused the victim’s injury or
• One year after the victim discovered or should have discovered the error that caused their injury.

Exceptions apply if the injury victim was a minor at the time of the incident. In that case, the discovery date is determined by when the parent or guardian discovered the malpractice in these cases. 

The Washington State Medical Malpractice Statute of Repose

While Washington state law historically maintained an eight-year statute of repose for medical malpractice claims, this is no longer the case.

Like the statute of limitations, a statute of repose bars certain legal claims if the claimant does not assert the complaint within a specific deadline. While the statute of limitations focuses on the timeliness of action (often tied to when an injury is discovered), a statute of repose focuses on immunizing the at-fault party from long-term liability by creating a strict, absolute outer deadline, regardless of when the victim discovered or should have discovered the injury.

For many years, Washington enforced an absolute eight-year statute of repose for medical malpractice. However, in December 2023, the Washington State Supreme Court struck this law down as unconstitutional. Because of this ruling, Washington no longer enforces a hard eight-year deadline for medical malpractice. Today, victims who do not reasonably discover a provider’s negligence until many years after the fact are not automatically barred from filing a lawsuit, provided they file within one year of discovering the injury.

Tolling the Medical Malpractice Statute of Limitations

Under certain circumstances, the time will stop running on the “clock” of the statute of limitations. In other words, the running of the limitation period is paused by specific events or circumstances. The exceptions apply in cases of fraud or intentional concealment or if the plaintiff is incompetent or cannot understand the nature of the proceedings. Further, good faith requests for mediation may toll the statute of limitations for one year. 

When to Sue for Medical Malpractice

Injury victims should consider suing if they suffered injuries because their healthcare provider breached their standard of care or failed to perform. Many types of negligence may cause harm to a patient. Moreover, the term “healthcare provider” extends to various types of clinicians. 

Under RCW 7.70.020, occupations that qualify as a healthcare provider include:

• Physicians,
• Osteopathic physicians,
• Dentists,
• Nurses,
• Chiropractors,
• Acupuncturists,
• Physical therapists, or
• Psychologists.

Further, hospital systems or facilities that employ the negligent healthcare provider may be liable for negligence. 

What Qualifies as Medical Malpractice

Medical malpractice generally falls under one of several different categories. These categories include the following. 

Misdiagnosis

Misdiagnosis refers to situations where a physician fails to recognize clinical signs and symptoms, order medical testing, or refer the patient to a specialist. 

Failure to Treat

Failure to treat violates the standard of care that healthcare professionals accept when treating a patient. This type of negligence may include releasing a patient too soon, failing to provide follow-up care, or ignoring a patient’s medical history. 

Lack of Sanitation 

Poor hygiene and sanitation practices can lead to serious and potentially deadly infections. Lack of sanitation can occur if medical staff fails to wash their hands, incorrectly disposes of hazardous materials, or fails to sanitize equipment. 

Additionally, surgical errors, medication errors, failure to diagnose, delayed diagnosis, and birth injuries are common forms of medical malpractice. 

These errors can lead to injuries that range in severity and longevity. While some patients may recover after medical malpractice, others may suffer the consequences for the rest of their life. 

Medical Malpractice Based on a Lack of Informed Consent 

In addition to the common forms of medical malpractice, informed consent is a necessary prerequisite to most medical care. Except in extreme cases, Washington State requires healthcare providers to inform and obtain patients’ consent before providing medical care. 

Generally, informed consent consists of providing patients with certain information such as:

• Qualifications of the treating healthcare provider,
• Purpose of the treatment, procedure, or medication,
• Potential risks and complications of the treatment,
• Alternatives to the treatment,
• Chance of the treatment’s failure or success,
• Length of recovery, and
• Estimated cost and insurance coverage of the procedure.

Informed consent is critical to ensuring that patients understand their options and risks. With this information, they can make the best decision for their unique circumstances. The failure to provide informed consent can lead to unwise and unsafe choices.

What is the statute of limitations for medical malpractice in Washington?

You generally must file within 3 years of the malpractice, or within 1 year of discovering (or reasonably should have discovered) the injury, whichever is later, under RCW 4.16.350.

Is there still an 8-year deadline (statute of repose) in Washington?

No. Washington’s 8-year statute of repose was ruled unconstitutional and unenforceable by the Washington Supreme Court in Bennett v. United States in 2023. The operative deadline is now the 3-year rule or the 1-year discovery rule.

What is the discovery rule?

The discovery rule lets you file within 1 year of when you discovered, or reasonably should have discovered, that a medical error caused your injury, even if that is more than 3 years after the malpractice. It exists because some injuries are not apparent right away.

Can the deadline be paused (tolled)?

Yes. The clock can be paused in situations such as when the patient is a minor, is legally incapacitated, or when a provider commits fraud, conceals the error, or leaves a foreign object in the body. A written request for mediation can also toll it for one year.

What happens if I miss the deadline?

If you file after the applicable deadline, the defendant will almost certainly move to dismiss, and the court will typically grant it, ending the case regardless of how strong it was. That is why confirming your deadline early matters.

How long do I have if the malpractice involved a child?

Claims involving minors are treated differently, and the deadline is often paused until the child reaches 18. The exact timing depends on the facts, so it is important to confirm with an attorney.

Do I need a medical expert to file?

In most Washington medical malpractice cases, you must file a certificate of merit from a qualified medical expert confirming a reasonable basis for the claim, so early expert review is part of preparing the case.

One verification note: I cited RCW 4.16.350, the Bennett v. United States (2023) ruling striking down the 8-year repose, the tolling rules, and the certificate-of-merit requirement. The Bennett holding is well documented, but given how consequential the deadline is, please have the attorney confirm all of this and approve the rewritten repose section before it goes live.
