In most of the United States, yes, a medical examiner must be a doctor. The position typically requires a medical degree (MD or DO) and specialized training in forensic pathology. However, the answer gets more complicated because many Americans actually live in jurisdictions that use coroners instead of medical examiners, and coroners usually do not need to be doctors at all.
Medical Examiners vs. Coroners
The U.S. has two parallel systems for investigating deaths, and they work very differently. A medical examiner is an appointed physician, almost always a forensic pathologist, who investigates suspicious, unexpected, or unexplained deaths. A coroner is typically an elected official who serves the same basic function but may have no medical background whatsoever. In most states, coroners are not required to be physicians or forensic pathologists. Some states require coroners to complete specific death investigation training, but the bar is far lower than a medical degree.
Which system you fall under depends entirely on where you live. About 17 states plus Washington, D.C. run centralized statewide medical examiner systems, including Connecticut, Maryland, Massachusetts, New Mexico, North Carolina, Oregon, and Virginia. Other states use county-based coroner systems (like Idaho, Indiana, Kansas, Nebraska, Nevada, and South Carolina), and many states use a mix of both. California, New York, Ohio, Illinois, and Georgia, for example, all operate county-level systems where some counties have medical examiners and others have coroners.
What Training a Medical Examiner Needs
Becoming a medical examiner is one of the longest training paths in medicine. It starts with four years of medical school to earn an MD or DO degree. After that comes a residency in anatomic pathology, the branch of medicine focused on examining tissues and organs to diagnose disease and determine cause of death. One common route is three years of anatomic pathology residency followed by a one-year fellowship specifically in forensic pathology. Another option is a five-year combined residency covering anatomic pathology, clinical (laboratory) pathology, and forensic pathology together. Either way, you’re looking at 12 to 13 years of education and training after high school before someone is fully qualified.
Forensic pathology fellowship programs, like the one at the Maryland Office of the Chief Medical Examiner, require applicants to hold a medical degree and have completed an accredited pathology residency before they can even apply. This level of training is what separates a medical examiner from a coroner: the ability to personally perform autopsies, interpret toxicology results, and make cause-of-death determinations based on direct examination of the body.
Who Can Actually Perform an Autopsy
Twenty states and Washington, D.C. have laws requiring that autopsies be performed only by pathologists. This is a critical distinction. Even in jurisdictions that use coroners, the coroner typically cannot perform an autopsy personally unless they happen to be a physician. Instead, they contract with or refer cases to a forensic pathologist. The coroner may have the legal authority to order an autopsy, but someone with medical training has to carry it out.
In a medical examiner system, the medical examiner both orders and performs autopsies. This consolidation of authority in a single trained physician is one of the main arguments supporters make for the medical examiner model over the coroner model.
How Offices Are Staffed
A medical examiner’s office is more than one person. It includes death investigators, toxicologists, administrative staff, and sometimes multiple forensic pathologists. The National Association of Medical Examiners (NAME), which accredits these offices, maintains detailed standards covering everything from facilities and evidence handling to workload limits. A single medical examiner performing more than 350 autopsies per year, for instance, is considered a serious enough problem to block accreditation.
Staffing is a real challenge in many parts of the country. There is a well-documented shortage of forensic pathologists in the U.S., and smaller or more rural offices often struggle to recruit qualified doctors. NAME has encouraged partnerships between smaller remote offices and better-staffed ones to help bridge gaps in expertise and resources.
Why the Distinction Matters
The difference between a medical examiner and a coroner can affect the quality and consistency of death investigations. A forensic pathologist brings years of specialized training to questions like whether a death was natural, accidental, a suicide, or a homicide. That determination shapes everything from criminal investigations to insurance claims to public health data. In coroner systems, the person making initial decisions about which deaths to investigate and how to classify them may be a funeral director, a sheriff, or someone with no medical or scientific training at all, though they are generally required to complete state-mandated death investigation courses.
Each state sets its own standards for what types of deaths trigger an investigation and what qualifications the investigating official needs. There is no single federal standard. So whether the person examining a death in your jurisdiction is a board-certified forensic pathologist or an elected official with a training certificate depends entirely on your state and county laws.
