Chiropractors call themselves doctors because they earn a Doctor of Chiropractic (DC) degree, a doctoral-level professional credential that is legally recognized in all 50 US states. The title works the same way it does for dentists (DDS), psychologists (PsyD), and optometrists (OD): it reflects the completion of a specific doctoral program, not a medical degree. Whether that feels equivalent to “doctor” as most people use the word is where the debate starts.
The Degree Behind the Title
A Doctor of Chiropractic program requires a minimum of 4,200 instructional hours across four academic years. Students complete coursework in anatomy, physiology, biochemistry, pathology, microbiology, and diagnosis before moving into clinical rotations where they treat patients under supervision. A comparative study published in the Journal of Manipulative and Physiological Therapeutics found that in basic sciences, chiropractic and medical programs are “more similar than dissimilar, both in the types of subjects offered and in the time allotted to each subject.”
That said, the programs diverge sharply after the basic sciences. Medical students spend years training in pharmacology, surgery, and hospital-based medicine. Chiropractic students spend that equivalent time on spinal manipulation techniques, musculoskeletal diagnosis, and rehabilitation. The foundations overlap, but the clinical training points in very different directions.
Licensing and Legal Recognition
Every US state grants chiropractors a license to practice and use the title “doctor.” This isn’t a gray area or a courtesy. In Florida, for example, state statute defines “doctor of chiropractic” and “chiropractic physician” as synonymous legal terms. Using those titles without a valid license is a first-degree misdemeanor. Similar protections and requirements exist nationwide.
To earn that license, chiropractors must pass a four-part national board examination administered by the National Board of Chiropractic Examiners. All 50 states either accept or require these exams. Part I covers basic sciences, Part II covers clinical sciences, Part III tests the ability to apply knowledge in clinical scenarios, and Part IV is a hands-on practical exam where candidates perform the kinds of assessments they’d use in practice. The structure mirrors, in broad strokes, the step-based licensing exams medical doctors take.
Chiropractic programs themselves are accredited by the Council on Chiropractic Education, which is recognized by the US Department of Education as the accrediting body for the profession. This is the same federal recognition process that validates medical school accreditation.
What Chiropractors Can and Can’t Do
The “doctor” title sometimes creates confusion because most people associate it with someone who can prescribe medication or perform surgery. Chiropractors cannot do either. Their scope of practice centers on diagnosing and treating musculoskeletal conditions, particularly those involving the spine, through manual adjustments, rehabilitation exercises, and lifestyle counseling.
They do, however, have broader diagnostic authority than many people realize. Chiropractors are trained to order and interpret lab tests including blood counts, metabolic panels, cholesterol panels, blood sugar markers, vitamin levels, and inflammatory markers. They can order imaging like X-rays and, in many states, refer for MRIs. Some states, like Arizona, classify chiropractors as “portal of entry” health care providers, meaning patients can see them as a first point of contact without a referral from another doctor.
After earning the DC, chiropractors can also pursue post-doctoral specialty certifications in areas like radiology, neurology, sports medicine, pediatrics, clinical nutrition, and rehabilitation. These board certifications require additional years of training and examination, and they’re recognized by the American Board of Chiropractic Specialties.
Why It Bothers Some People
The tension around the title comes down to public expectation. When most people hear “doctor” in a healthcare setting, they picture a medical doctor, someone who completed medical school, a residency, and who can prescribe drugs and perform procedures. A chiropractor’s training is genuinely rigorous, but it prepares them for a fundamentally different role. Critics argue that using “doctor” without immediately clarifying “of chiropractic” can mislead patients into assuming a broader scope of training than the person actually has.
Chiropractors counter that the word “doctor” has never belonged exclusively to MDs. It originally comes from the Latin word for “teacher,” and doctoral degrees exist across dozens of fields. Pharmacists hold a Doctor of Pharmacy. Physical therapists now earn a Doctor of Physical Therapy. Nurses can hold a Doctor of Nursing Practice. In each case, the title reflects doctoral-level education in a specific discipline, not equivalence with physicians.
The practical reality is that the title is both legally protected and professionally earned. A chiropractor who introduces themselves as “doctor” is doing exactly what their license, their degree, and their state law permit. The responsibility falls on both the provider and the patient to be clear about what kind of doctor is in the room, just as it does with any other non-MD doctoral provider in healthcare.
