What Is the Deadline for Filing a Maryland Medical Malpractice Claim?
Most Maryland medical malpractice claims must be filed by the earlier of five years after the injury was committed or three years after the injury was discovered. Special rules may apply to children, people with mental incapacity, concealed wrongdoing, and claims involving a patient's death.
A medical mistake does not always reveal itself right away. The filing deadline may still be moving.
You may be waiting for test results, seeking a second opinion, or trying to understand why a loved one's condition became worse. A hospital may still be reviewing what happened. None of that necessarily pauses Maryland's statute of limitations.
The deadline may turn on when the injury occurred, when you discovered it, and whether a special rule applies. Learning these rules early gives you time to obtain records and protect your ability to seek answers.
Key Takeaways
- A claim generally must be filed within 5 years of the injury or 3 years of its discovery, whichever comes first.
- The discovery period may begin before a doctor or hospital admits that anything went wrong.
- Maryland courts apply special protections to a child's own medical malpractice claim.
- A wrongful death claim generally must be filed within three years after the patient dies.
- Most substantial malpractice claims begin with the Health Care Alternative Dispute Resolution Office.
- A qualified medical professional generally must support the claim with a certificate filed within 90 days.
What Is Maryland's Medical Malpractice Statute of Limitations?
Maryland uses two deadlines for medical malpractice claims. The earlier deadline usually controls.
Under Maryland Courts and Judicial Proceedings Section 5-109, a claim generally must be filed within:
- Five years after the time the injury was committed
- Three years after the date the injury was discovered
Many people see the five-year period and assume they have plenty of time. That can be a costly mistake. If you knew or reasonably should have known about the injury when it occurred, the three-year deadline may expire first.
You may also discover an injury several years after negligent care. In that situation, the five-year deadline may cut off the claim before three full years have passed from discovery.
How the Two Deadlines Work Together
Suppose a patient is injured during surgery on June 1, 2023 and immediately has reason to suspect a medical error. The three-year discovery deadline would generally point to June 1, 2026. That date arrives before the five-year deadline.
Now suppose the injury occurred on June 1, 2023 but was not discovered until June 1, 2027. Three years from discovery would point to 2030. The five-year period would point to June 1, 2028. The earlier date would generally control.
In a real case, the parties may disagree about when the injury was committed or discovered.
When Is a Medical Injury Considered Discovered?
An injury may be considered discovered when you know, or reasonably should know, enough facts to investigate whether medical care caused your harm.
You do not necessarily need a written opinion stating that malpractice occurred. You may not need to know the exact provider responsible or the full extent of the damage.
The clock could become an issue when:
- A second doctor questions an earlier diagnosis
- A surgical complication has no clear explanation
- An abnormal test result was never communicated
- An infection worsened despite repeated requests for care
- A retained object is found after surgery
- A child is diagnosed with a condition tied to oxygen loss during birth
- The records do not match what the family was told
These facts do not automatically prove malpractice. The question is whether the deadline would cause a reasonable person to investigate.
Does the Clock Begin on the Date of Treatment?
Not always. Maryland's five-year deadline runs from the time the injury was committed, which may not be identical to the date of the negligent act.
Some cases involve one clear event, such as a medication overdose. Others develop over time. A delayed cancer diagnosis may involve several missed scans, while a birth injury may involve failures before, during, and after delivery.
Determining the injury date may require a full medical timeline and review by a qualified professional. Choosing the last appointment or first symptom without that review can lead to the wrong calculation.
SCHEDULE A CONSULTATIONDo Children Have More Time to File?
A child's own medical malpractice claim receives special protection under Maryland law.
In Piselli v. 75th Street Medical, Maryland's highest court held that the statute could not begin running against a child's claim before the child turned 18. When the injury is already known at that point, age 21 may become an important deadline.
That does not mean a birth injury case can safely wait until the child approaches adulthood.
These cases often depend on fetal heart monitoring strips, cord blood results, newborn imaging, placental pathology, and opinions from several medical fields. Records become harder to locate, and memories fade.
Parents may also have claims that are separate from the child's claim and subject to different deadlines. An early review protects the evidence and helps the family understand every claim that may be available.
What Other Rules May Change the Deadline?
Several narrow rules may affect when a claim must be filed. None should be assumed to apply without reviewing the specific facts.
Mental Incapacity
A person who was mentally incompetent when the claim accrued may receive additional time. A serious illness, disability, or difficult recovery does not automatically establish legal incompetence.
The question is whether the person could protect their legal rights during the relevant period. Medical records, guardianship documents, and cognitive evaluations may matter.
Fraudulent Concealment
The deadline may be affected when a provider deliberately hides facts that kept the patient from discovering the claim.
A hospital's refusal to admit fault is not automatically fraud. Concealment may involve intentionally altering records, hiding findings, or knowingly giving false information about what occurred.
Save every version of the records you receive. Later-produced charts may reveal important differences.
Ongoing Treatment
Continuing to be treated by the same doctor does not automatically pause the filing deadline. Patients sometimes assume the clock will not start until treatment ends. That is not a safe assumption.
The treatment relationship may affect when you reasonably should have investigated the injury, but it does not create a simple extension in every case.
How Long Do Families Have After a Malpractice-Related Death?
A Maryland wrongful death claim generally must be filed within three years after the patient dies.
A death caused by medical negligence may create more than one claim. A wrongful death claim addresses losses suffered by qualifying family members. A survival claim addresses the harm the patient experienced before death and belongs to the patient's estate.
The deadlines may not be identical. The date of death generally starts the wrongful death period, but it may not restart an expired medical malpractice claim belonging to the patient. Both claims should be reviewed separately.
Does Complaining to the Hospital Stop the Clock?
No. A hospital complaint should not be treated as a legal filing.
Hospitals may direct patients to risk management or an internal grievance process. Families may also report a provider to a licensing board. Those steps may produce information, but they generally do not preserve a malpractice claim.
Do not assume the deadline has stopped because:
- The hospital says it is investigating
- An insurer requested additional records
- A doctor promised to respond
- A licensing complaint is pending
- Settlement discussions have started
- You requested your medical chart
You can seek answers while separately preserving the legal claim.
Where Is a Maryland Medical Malpractice Claim Filed?
Most substantial Maryland medical malpractice claims must begin with the Health Care Alternative Dispute Resolution Office, often shortened to HCADRO.
Maryland treats a properly filed HCADRO claim as the filing of the action for statute of limitations purposes. Filing in the wrong place or waiting to complete the required process can put the case at risk.
The claimant must generally file a certificate from a qualified medical professional within 90 days after filing the claim. Under Maryland Courts and Judicial Proceedings Section 3-2A-04, the certificate must state that the provider departed from the applicable standard of care and that the departure caused the injury.
A supporting report must also be attached in most cases.
Waiting until the final week is dangerous. Records must be collected, and the right medical professional needs time to review the care.
What Should You Do When the Deadline May Be Close?
Start by writing down the medical timeline as accurately as you can.
Include:
- Dates of appointments, procedures, hospital stays, and diagnoses
- When symptoms appeared or became worse
- What each provider told you
- When you first suspected a medical error
- When another provider questioned the care
- Dates of later treatment connected to the injury
- Any change in the hospital's explanation
Keep patient portal messages, photographs, discharge papers, test results, bills, and letters. Do not wait for every record before asking for a legal review.
You do not need to prove the case during the first conversation. The immediate goal is to identify the possible deadlines and decide whether the care warrants a deeper investigation.
Do I Always Have Five Years to File?
No. The three-year discovery deadline may expire first.
If you knew or reasonably should have known about the possible injury when it occurred, you may have closer to three years than five.
Does the Clock Start When a Doctor Confirms Malpractice?
Not necessarily. The clock may begin when you have enough information to investigate, even if no doctor has used the word "malpractice."
Waiting for a provider to admit fault can consume time you do not have.
Can I File More Than Three Years After Treatment?
Possibly. The answer depends on when the injury was committed, when it was discovered, and whether an exception applies.
The five-year outside period may still limit the time available.
Does a Hospital Investigation Extend the Deadline?
Not by itself. An internal review is separate from the legal filing process.
Continue cooperating if the investigation may help, but do not rely on it to preserve the claim.
What Happens If the Deadline Expires?
The health care provider can ask the court to dismiss the claim as untimely.
A strong case can be lost without any decision about whether the provider was negligent. The filing deadline can become a complete defense.
Protecting Your Right to Ask What Happened
