A coroner is typically an elected official who may have no medical training, while a medical examiner is an appointed physician, usually a forensic pathologist, who specializes in determining cause of death. Both roles exist to investigate deaths that are unexpected, violent, or suspicious, but they differ significantly in qualifications, authority, and how they get the job.
How Each Role Is Selected
The most fundamental difference is how each person ends up in the role. Coroners are usually elected by voters in their county, much like a sheriff or a judge. Depending on local laws, a coroner might also be appointed, and in some jurisdictions the coroner doubles as a law enforcement officer or even a prosecuting attorney. There is no nationwide requirement that a coroner have any medical background at all.
Medical examiners, by contrast, are appointed to their positions. They are always physicians, and most are board-certified forensic pathologists. Becoming one requires four years of medical school, a four-year residency in pathology, and an additional one-year fellowship in forensic pathology. That is roughly nine years of training after college, focused specifically on understanding how and why people die.
Qualifications and Training
In many states, the only qualification to run for coroner is being a legal adult and a resident of the county. That means a coroner could be a farmer, a funeral director, a retired teacher, or anyone else willing to run for office. Some coroners do happen to be physicians, and coroners who are forensic pathologists exist, but the office does not require it.
Medical examiners must hold board certification in forensic pathology from the American Board of Pathology. The National Association of Medical Examiners (NAME), which accredits death investigation offices, requires that the chief medical examiner be a certified forensic pathologist with at least two years of work experience beyond fellowship training. This accreditation also mandates specific facility standards, safety protocols, and access to accredited toxicology labs.
Who Actually Performs Autopsies
This is where the distinction matters most in practice. Even in coroner-run jurisdictions, a coroner without medical training cannot personally perform an autopsy. State laws require that autopsies be conducted by a licensed physician, preferably one with special training in pathology. In Illinois, for example, a coroner is explicitly prohibited from performing an autopsy unless that coroner is a pathologist. Instead, the coroner must designate or hire a qualified physician to do the work.
A medical examiner, being a forensic pathologist, performs autopsies directly. They can integrate what they find on the autopsy table with evidence from the scene and laboratory results to reach a conclusion about how someone died. This ability to personally conduct and interpret autopsies is the core professional advantage of the medical examiner system.
Legal Powers
Coroners actually hold certain legal powers that medical examiners typically do not. Because the coroner’s office traces back to 12th-century England (the role was created in 1194 to protect the interests of the Crown), coroners inherited quasi-judicial authority. They can issue subpoenas and convene a coroner’s inquest, which is a formal proceeding to determine the circumstances of a death. An inquest can compel witnesses to testify under oath.
Medical examiners function as scientific experts rather than legal officers. They determine cause and manner of death based on medical evidence and may testify in court as expert witnesses, but they do not have independent subpoena power or the authority to hold inquests. Their role is investigative and medical, not judicial.
How the U.S. Is Split
The United States has no single, unified system for death investigation. As of 2024, 23 states and the District of Columbia use medical examiner systems. Eleven states use coroner systems across all their counties, and 14 others use coroners in some counties but medical examiners in others. In total, there are more than 2,000 death investigation offices nationwide: roughly 1,630 coroner offices, 384 city, county, district, or regional medical examiner offices, and 22 state-level medical examiner offices.
This patchwork means the quality and consistency of death investigations can vary dramatically depending on where someone dies. Coroner statutes tend to be less specific about which deaths must be reported or investigated, and the standards for investigation often reflect the qualifications of whoever holds the office. A well-funded medical examiner’s office with NAME accreditation operates very differently from a rural coroner’s office where the coroner has no medical background and contracts out autopsy work.
Pay Differences
Medical examiners generally earn more than coroners, which reflects their extensive education and specialized training. Coroner salaries range widely, from about $50,000 to over $300,000 a year. That enormous spread exists because some coroners are part-time elected officials in small counties while others are forensic pathologists running large offices. A coroner who is also a forensic pathologist earns far more than an elected coroner without a medical background.
Why It Matters
The difference between these two systems has real consequences. When a death is investigated, the determination of cause and manner of death affects criminal prosecutions, insurance claims, public health data, and families seeking answers. In a medical examiner system, that determination is made by someone trained to interpret physical evidence at the cellular level. In a coroner system, the official responsible for the case may be relying entirely on a contracted physician’s findings, filtered through their own nonmedical judgment. Both systems can work well when properly resourced and staffed, but the medical examiner model is generally regarded as the more scientifically rigorous approach to death investigation.
