You can sue if you get an infection after surgery, but only when the infection resulted from a healthcare provider’s preventable mistake rather than the ordinary risks of the procedure. Surgical site infections affect roughly 2 to 4 percent of patients undergoing inpatient procedures, making them the most common preventable complication after surgery.1Agency for Healthcare Research and Quality. Surgical Site Infections The legal question is not whether you got sick. It is whether something went wrong that shouldn’t have.
When an Infection Becomes Malpractice
Infection is a recognized risk of nearly every operation, and your surgical team is required to warn you about it during informed consent. That signature you gave before surgery covers risks that persist even when everyone does their job correctly.2National Center for Biotechnology Information. Informed Consent for Surgery: Risk Discussion and Documentation It does not give the team permission to be careless.
The legal test turns on the “standard of care,” meaning the level of skill and attentiveness that a reasonably competent provider in the same specialty would deliver in the same situation. Most states measure this against a national standard.3National Library of Medicine. The Standard of Care Conduct that falls below that benchmark is a breach of duty, and a breach is the foundation of every malpractice claim.
Infections trace back to failures at any stage of care:
- Before surgery: failing to screen for risk factors, skipping preoperative antibiotics when guidelines call for them, or inadequately preparing the surgical site.
- During surgery: using contaminated instruments, breaking sterile technique, or operating in an environment that doesn’t meet infection-control standards.
- After surgery: neglecting to give clear wound-care instructions, failing to prescribe appropriate antibiotics, or dismissing early signs of infection when a patient reports redness, swelling, fever, or discharge.
That last category is where many infection claims actually originate. The surgery itself may have gone fine, but a provider who ignores a developing infection and delays treatment can turn a minor complication into a life-threatening one. A delay of even a few days can be the difference between oral antibiotics and emergency surgery.
Your own health matters here too. Diabetes, obesity, and a weakened immune system all raise infection risk regardless of the care you receive, and a defense team will almost certainly argue that your health, not their conduct, is the real cause. That doesn’t sink your case, but it means your evidence has to connect the infection to a specific failure.
What You Have to Prove
A malpractice claim requires four elements. Miss one and the case fails regardless of how strong the others are.
Duty and Breach
A provider-patient relationship automatically creates a duty of care. The fight is over breach: you need to show the provider did something, or failed to do something, that a competent peer would not have done. This almost always requires testimony from a medical expert in the same specialty who can explain what should have happened and how the defendant fell short.4National Center for Biotechnology Information. The Expert Witness in Medical Malpractice Litigation
Causation
Proving a mistake is not enough. You also have to prove the mistake caused your infection, meaning it wouldn’t have occurred, or wouldn’t have been as severe, without that specific error.5National Library of Medicine. Utilizing Causation Causation is often the hardest element in infection cases, because infections can develop even with flawless care and defendants will argue yours was going to happen anyway.
Damages
You must show the infection caused real, measurable harm. If it cleared quickly with no additional treatment, there may not be enough harm to support a claim. Stronger cases involve infections that required additional surgeries, extended hospital stays, long-term antibiotic therapy, or left permanent effects.
Who You Can Sue
A post-surgical infection may point to the surgeon, the nursing staff, the anesthesiologist, the hospital itself, or some combination. Each raises different legal questions.
Hospitals are generally liable for the negligence of their employees under a principle called respondeat superior, which holds an employer responsible for the acts of employees working within the scope of their job.6National Library of Medicine. Responsibility for the Acts of Others If a staff nurse failed to follow sterilization protocols, the hospital typically shares liability. Hospitals can also be directly liable for systemic failures like inadequate infection-control policies, understaffing, or poorly maintained equipment.
Surgeons and specialists are more complicated. Many hospital-based physicians work as independent contractors, and respondeat superior generally does not reach independent contractors, so you may need to sue the doctor directly. If the hospital created the impression that the physician was part of its staff, some courts still hold the hospital liable under a doctrine called ostensible agency. The key question is whether you had reason to believe you were receiving care from the hospital’s own team rather than from an outside contractor.
How Long You Have to File
Every state imposes a statute of limitations on medical malpractice claims, and missing it means losing your right to sue entirely. Filing windows typically range from one to four years, but both the length and the starting point vary by state.
The Discovery Rule
Many states follow a discovery rule that delays the start of the deadline until you discover the injury and connect it to the provider’s negligence. This matters for infection cases because symptoms may not appear for weeks or months after surgery. The standard is objective: the clock starts when a reasonable person in your position would have recognized the problem through ordinary diligence, not necessarily when you personally put the pieces together.
Statutes of Repose
Even in discovery-rule states, there is usually an outer boundary called a statute of repose. This is an absolute deadline, typically three to ten years from the date of the surgery itself, regardless of when you discovered the infection. If the repose period expires before you learn about the negligence, you may be barred from filing no matter how reasonable your delay was. A handful of states have no medical malpractice repose statute, but most do.
State deadlines also change. Checking your state’s current law early is one of the most consequential things you can do.
Steps Some States Require Before You File
Many states impose procedural requirements that must be completed before you can file suit. Skipping them can get a strong case dismissed on technical grounds.
Affidavit or Certificate of Merit
Roughly 29 states require plaintiffs to file an affidavit or certificate of merit with the complaint or shortly after. It is a sworn statement from a qualified medical expert confirming that they have reviewed your case and believe the defendant fell below the standard of care. Some states require it at the time of filing; others allow 60 to 90 days. Failing to provide one on time can get your case thrown out.
Pre-Suit Notice
Some states require you to notify the healthcare provider of your intent to sue before filing. Florida, for instance, requires an investigation confirming reasonable grounds before a notice of intent can even be sent. West Virginia mandates at least 30 days’ notice. These rules give providers a chance to settle early and create a structured window for both sides to evaluate the claim.
What You Can Recover
Compensation falls into two main categories, with a third reserved for extreme cases.
Economic Damages
Economic damages reimburse measurable financial losses tied to the infection: hospital readmission, follow-up surgeries, antibiotics, rehabilitative therapy, and other medical bills. Lost wages count too, both income already missed and future earning capacity if the infection left you unable to return to your previous work. Home health aides, medical equipment, and transportation to appointments are also recoverable.
Non-Economic Damages
Non-economic damages compensate for harms that don’t come with a receipt: physical pain, emotional distress, scarring or disfigurement, and the loss of activities you can no longer enjoy. Juries have wide discretion in setting these amounts.
Roughly half of states cap non-economic damages in medical malpractice cases, and the caps vary widely. California limits non-economic damages to $430,000 in cases not involving death (as of 2025), with scheduled annual increases. Other states set caps as low as $250,000 or as high as $875,000, and some include exceptions for severe injuries or wrongful death. Caps do not reduce economic damages, but they can significantly limit your total recovery, which is worth understanding before pursuing a case.
Punitive Damages
In rare situations where the provider’s conduct went beyond ordinary negligence into reckless or intentional territory, courts may award punitive damages. These are not meant to compensate you; they are meant to punish the defendant. The threshold is much higher, requiring evidence of gross negligence, willful misconduct, or malice. A provider who knowingly operated with contaminated equipment or falsified sterilization records might face punitive exposure. Most infection cases don’t reach this bar, and many states cap punitive damages separately.
What to Do Now
Start gathering records immediately. Request your complete medical chart, including the operative report, anesthesia records, nursing notes, lab results, and all post-operative documentation. Take dated photographs of the infection site as it develops. Keep a daily journal noting your symptoms, pain levels, and how the infection affects your ability to work and live normally. Save every bill, receipt, and insurance explanation of benefits.
Line up a medical expert early. Expert testimony is nearly always required to define the standard of care, explain how the defendant breached it, and connect that breach to your infection.4National Center for Biotechnology Information. The Expert Witness in Medical Malpractice Litigation The expert must typically practice in the same specialty as the defendant, and in states requiring an affidavit of merit, you need that opinion before the lawsuit even gets off the ground.
Most medical malpractice attorneys work on contingency, meaning no attorney fees unless you recover. Contingency rates typically run between 33 and 40 percent. You may still be responsible for case expenses like expert witness fees, medical record retrieval, and court filing costs, which can add up quickly in a complex case. Ask about those costs upfront.
