Maryland Medical Malpractice Law

This page summarizes the key medical malpractice laws in Maryland you need to understand to bring a malpractice lawsuit in Maryland.

What You Need to Get a Case Filed | Certificate of Merit

In Maryland, you cannot just walk down to the appropriate circuit court and file a lawsuit.  Maryland requires that a medical doctor provide written support for any medical malpractice claim.

Under Md. Code Ann. Courts and Judicial Proceeding Section 3-2A-04 (b)(4), medical malpractice lawyers must file a qualified expert’s statement that the doctor’s care violated applicable standards of care and proximately caused the plaintiff’s injury.

To limit “hired gun” experts, the expert’s statement must come from a doctor who makes less than 20% of his/her income from testimony in personal injury claims. The time counting toward the 20 percent limit is:

  1. time spent in, or traveling to or from, court or deposition for testifying, waiting to testify, or observing events in preparation for testifying;
  2. time spent assisting an attorney in preparing or responding to discovery;
  3. time spent reviewing material and conferring with others after being told he/she would likely be asked to sign an affidavit or testify; and
  4. time spent on similar activity with a clear and direct relationship to testimony to be given or preparation to give testimony.

Lawyers have destroyed many trees interpreting these four requirements. Plaintiffs’ and defense counsel have interpreted these requirements very differently.

Maryland requires that the certificate of a qualified expert explicitly state the name of the doctor or health care professional who allegedly breached the standard of care.

Statutes of Limitations

malpractice laws

Statues of Limitations are the deadlines to file particular lawsuits. Failure to submit a lawsuit within the deadline can be a complete bar to recovery.

This area of medical malpractice law can be confusing, and the exact rules depend on the particular facts of a case.

In general, however, medical malpractice lawsuits on behalf of adults in Maryland must be filed either within five years of the date when the injury was committed or three years of the date when the injury was reasonably discoverable, whichever is earlier. Md. Code Ann., Cts. & Jud. Proc. § 5-109.

For minors, the deadline to file a medical malpractice lawsuit does not begin to run until they reach the age of 18.

Wrongful death actions are treated differently. A wrongful death action is a lawsuit filed by the loved ones of someone who died as a result of negligence. Those lawsuits must be filed within three years of the date of death. Md. Code Ann., Cts. & Jud. Proc. § 3-904.

In most medical malpractice cases, when a person dies there are two causes of action.

The first is a “survival action,” filed by the estate for the medical expenses and pain and suffering endured by the decedent (the person who died).

The second is the “wrongful death” action, filed by the loved ones for their pain and suffering caused by the loss of the decedent. The survival action has the same statute of limitations as an ordinary medical malpractice case.

It is harder to determine the deadline for cases of misdiagnosis or delayed diagnosis of a medical condition, like cancer. There, it is simple to determine when the diagnosis was incorrectly made.

However, the clock starts to run when the plaintiff first suffers “injury.” It can be difficult to determine to the date that the plaintiff suffered injury, and exactly what constitutes a legal injury allowing the plaintiff to file a lawsuit. See Edmonds v. Cytology Services, 111 Md.App. 233, 681, A.2d 546 (1995). The Court in Edmonds gave non-exhaustive list of possibilities as to when an injury arises:

  1. the plaintiff experiences pain or other manifestation of an injury;
  2. the disease advances beyond the point where it was at the time of the misdiagnosis and to a point where
    1. it can no longer effectively be treated,
    2. it cannot be treated as well or as completely as it could have been at the time of the misdiagnosis, or
    3. the treatment would entail expense or detrimental side effects that would not likely have occurred had treatment commenced at the earlier time;
  3. the patient dies.

Additionally, lawsuits against local, state, and federal governments have “notice” requirements. This means that, within a certain time after the negligence, a claimant must notify the government that he or she may have a claim.

The federal government typically requires notice within 2 years of the negligence.

The State of Maryland typically requires notice within one year after the date of injury (Md. Code Ann., State Gov’t § 12-106). Maryland local governments require notice within 180 days after the date of injury (Md. Code Ann., Cts.&Jud. Proc. § 5-304).

  • Get even more detail on the nuances of the statute of limitation in Maryland health care negligence claims. These cases can be tricky.

Limits on Recoverable Damages (“Caps”)

In medical malpractice cases, plaintiffs can recover any “economic” damages that were caused by the negligence. For example, they may recover the cost of paying for future surgeries, their lost wages, and any prescriptions or assistive devices required because of the negligence.

However, the Maryland legislature has limited the amount of “non-economic” damages (typically called “pain and suffering”) plaintiffs can receive in medical malpractice cases. In fact, the amount is even lower than other injury cases.

There is a formula to determine the limit based on the year the claim arises. For Maryland medical malpractice cases arising in 2023, the cap on non-economic damages is $875,000. The cap increases to $1,093,750 medical malpractice wrongful death claims brought by two or more surviving family members under the Maryland Wrongful Death Statute. (The math on that is the malpractice damages cap multiplied by 1.25.)

Under Maryland malpractice law, if a surgeon negligently performed an operation that caused the death of his patient two years later, the most that could be recovered for the estate and for all family members entitled to recover for non-economic damages is $1,093,750.

(Compare that to other forms of personal injury—if the doctor hit someone with his car while running a red light, and that person died from his injuries two years later, the maximum amount of non-economic damages would be $2,225,000. Big difference.)

Additionally, Maryland governments have caps on damages that may be recovered against them in lawsuits. The liability of the State of Maryland cannot exceed $400,000 per claimant from a single incident (Md. Code Ann., State Gov’t § 12-104). The liability of Maryland’s local governments is limited to 4200,000 per individual claim, and $800,000 for the total claims arising from a single occurrence (Md.. Code Ann., Cts.&Jud. Proc. § 5-303).

Mandatory Arbitration (The Health Care Alternative Dispute Resolution Office)

Maryland technically has mandatory arbitration in medical malpractice cases in Maryland. The Maryland Health Care Malpractice Claims Statute, Md. Code Ann., Cts.&Jud. Proc. § 3-2A-04 requires that medical malpractice parties arbitrate their claims before the Health Care Alternative Dispute Resolution Office as a condition precedent to bringing a lawsuit in Circuit Court.

But malpractice lawyers in Maryland regularly waive arbitration as permitted under the statutory scheme at any time after filing the certificate of a qualified expert.

Informed Consent

Maryland informed consent law is based on the patient’s right to exercise control over his body.

The informed consent doctrine imposes on a physician and obligation to explain the procedure or therapy to the patient and to warn her of any material risks or dangers inherent in or collateral to the therapy. This gives the patient the ability to make an intelligent and informed choice about whether or not to undergo such treatment.

There is no bright-line test in Maryland for determining the scope of disclosure required. The test for determining whether a potential peril must be divulged is its materiality to the patient’s decision. Accordingly, no expert testimony is required to bring a medical malpractice action claiming lack of patient consent.

Loss of Chance

loss of chance

Maryland is one of 24 states that has rejected the loss of chance doctrine. Accordingly, loss of chance damages are not recoverable in a medical malpractice wrongful death action brought under the Wrongful Death Act, Md. Code Ann., Cts. & Jud. Proc. § 3-901.

To recover under the wrongful death statute, the medical malpractice plaintiff must prove by a preponderance of the evidence that the death was caused by the medical malpractice of the health care provider. Fennell v. Southern Maryland Hospital, 320 Md. 776, 580 A.2d 206 (1990).

Proof that the medical malpractice defendant’s negligence reduced the decedent’s chance of survival by twenty to thirty percent – e.g., from eighty percent to between fifty and sixty percent which was the case in Marcantonio v. Moen, 177 Md. App. 664 (2007) – does not show a “probability” that the negligence caused the decedent to die. (We believe this is bad law. As the dissent in Moan points out, the 51% math is illogical because the majority’s calculation pretends it does not know that the patient died. If you have a 99% chance of living and the defendant’s negligence takes you down to 50% and you die, there is a 98% chance you died as a result of the negligence of the defendant. Hopefully, this issue will be addressed by the Maryland Court of Appeals or the Maryland General Assembly).

Obvious Negligence: “Res Ipsa Loquitur

In Maryland, the doctrine of “res ipsa loquitur” (Latin for “the thing speaks for itself”) allows plaintiffs to bring lawsuits without expert testimony if the injury:  (1) is a kind that does not usually happen without negligence, (2) is caused by an instrumentality exclusively within the defendant’s control, and (3) is not caused by any act or omission of the plaintiff.

As a practical matter, very few examples of res ipsa loquitur in healthcare.  Most attorneys prefer to have an expert testify as to exactly what went wrong. Get more on res ipsa loquitur here.

Admission of Medical Records

Hospital records in medical malpractice cases in Maryland are admissible if expert testimony establishes they are “pathologically germane” to the physical condition that caused the patient to go to the hospital in the first place.

A “pathologically germane” statement must fall within the broad range of facts which, under hospital practice, are considered relevant to the diagnosis or treatment of the patient’s condition. Facts helpful to an understanding of the medical or surgical aspects of the case within the scope of medical inquiry are pathologically germane.

Therefore, entries in hospital records which are pathologically germane, or relevant to the diagnosis or treatment of the patient’s condition, typically fall within the business records exception to the hearsay rule.

Venue Preference

There is no secret that medical malpractice lawyers in Maryland representing victims prefer the courts in Baltimore City or Prince George’s County.

To varying degrees, other Maryland jurisdictions are more conservative on questions of liability and damages. Plaintiffs do not always have a choice of where to file the lawsuit, however. Venue is governed by Md. Code Ann., Cts.&Jud. Proc. §§ 6-201 and 6-202.

Most medical malpractice cases are filed where the negligence occurred (for example, the county where the surgery or birth injury happened).

Contributory Negligence

Maryland is one of five jurisdictions in the United States (along with Virginia, District of Columbia, Alabama, and North Carolina) that continues to use contributory negligence instead of comparative negligence in medical malpractice (or any other negligence) cases.

Any contributing negligence by the Plaintiff, even one percent of negligence, will completely bar his/her recovery. That said, Maryland juries often overlook the Plaintiff’s negligence if it is a relatively insignificant part of the injury.

Most Maryland lawyers will tell you that if our state had comparative negligence, many jury verdicts in medical malpractice cases would be slightly reduced by the Plaintiff’s comparative negligence, usually for some patient noncompliance.

Still, almost every medical malpractice lawyer in Maryland would tell you that comparative negligence is a better and fairer system for malpractice plaintiffs.

In the 2021 session, there was hope for a change to Maryland’s contributory negligence law in the Maryland legislature. The Maryland high court has been baiting the legislature to do just that. This effort failed to change Maryland’s harsh contributory negligence standard.

In medical malpractice cases, however, contributory negligence of the Plaintiff does not occur as frequently as it does in other cases (for example, automobile negligence).  Why?  The rule contributory negligence in medical negligence cases in Maryland requires that the patient’s negligence must be concurrent with the doctor’s negligence.

So if it occurs after the physician’s negligence and just makes the problem worse, it is not contributory negligence. Santoni v. Schaerf, 48 Md. App. 498, 428 A.2d 94, 99 (1981),

Joint and Several Liability

In Maryland, where there are multiple defendants who each contributed to the negligence and injury, each defendant is jointly and severally liable. This means that each is responsible for the full amount of any judgment. However, if one defendant pays more than his fair share of the verdict, he may recover “contribution” from other responsible defendants to the claim.

Collateral Source

The Maryland’s collateral source rule permits tort victims to recover the full amount of his/her damages “regardless of the amount of compensation which the person has received for his injuries from sources unrelated to the tort-feasor.” Haischer v. CSX Transp., Inc., 381 Md. 119, 132, 848 A.2d 620, 628-29 (2004).

Regrettably, there is a malpractice exception to this rule to money that the Plaintiff actually paid or will have to pay.
