In the United States, yes. An osteopathic physician holds a Doctor of Osteopathic Medicine (DO) degree and is a fully licensed doctor who can prescribe medications, perform surgery, and practice in any medical specialty. The distinction gets more complicated outside the U.S., where the title “osteopath” can mean something quite different.
Two Paths to Becoming a Physician in the U.S.
The U.S. has two types of medical degrees that lead to full physician licensure: the MD (Doctor of Medicine) and the DO (Doctor of Osteopathic Medicine). Both require four years of medical school after completing an undergraduate degree, followed by three to five years of residency training. Both take board exams. Both can specialize in anything from family medicine to neurosurgery to psychiatry.
As of 2024, the Federation of State Medical Boards counts 1,082,187 actively licensed physicians in the U.S. About 89% hold an MD, while 11% hold a DO. That 11% share has been growing steadily as more osteopathic medical schools have opened in recent decades.
What DOs Can Legally Do
U.S.-trained osteopathic physicians practice the full, unlimited scope of medicine. They can prescribe all controlled substances, obtain hospital privileges, perform surgery, and participate in managed care contracts. There is no legal distinction between what an MD and a DO are permitted to do in clinical practice.
This wasn’t always the case. In the mid-20th century, roughly a dozen states restricted DOs from performing surgery or prescribing certain drugs. Those limitations have been eliminated, and today every state grants DOs the same practice rights as MDs.
Same Residencies, Same Standards
A major milestone came in 2020 when the U.S. completed its transition to a single residency accreditation system. Previously, DO graduates could train in osteopathic-specific residency programs accredited by the American Osteopathic Association or in programs accredited by the Accreditation Council for Graduate Medical Education (ACGME), which had historically served MD graduates. Now all residency and fellowship programs fall under the ACGME, meaning MD and DO graduates train side by side, meet the same competency milestones, and are evaluated by the same standards.
Board certification works the same way. To become board certified through the American Board of Medical Specialties, a physician needs a medical degree (MD or DO), completion of an accredited residency, and a passing score on specialty board exams. The credential is identical regardless of which medical degree the physician holds.
How DO Training Differs
The core medical curriculum at osteopathic and allopathic (MD) schools covers the same ground: anatomy, pharmacology, pathology, clinical rotations in major specialties. The key difference is that DO students also learn osteopathic manipulative treatment (OMT), a hands-on approach to diagnosing and treating musculoskeletal problems. OMT involves techniques like stretching, gentle pressure, and joint mobilization.
Osteopathic medical education also emphasizes a philosophical framework that treats the body as an interconnected system and stresses preventive care. In day-to-day practice, though, most DOs function identically to their MD counterparts. Many DOs rarely use OMT after residency, particularly those in specialties like radiology or anesthesiology where it doesn’t apply.
Patient Outcomes Are the Same
A large study published in the Annals of Internal Medicine in 2023 looked at hospital data for 329,500 Medicare patients aged 65 and older, treated between 2016 and 2019. Mortality rates were essentially identical: 9.4% for patients treated by MDs versus 9.5% for those treated by DOs. Readmission rates were 15.7% versus 15.6%. Average hospital stays were four and a half days for both groups. Even Medicare spending per patient differed by just one dollar. By every measurable outcome, patients fared the same regardless of their physician’s degree type.
Why It’s Different Outside the U.S.
This is where the confusion often starts. In the United Kingdom, an osteopath is not a physician. Osteopathy is regulated as a separate, primary-contact healthcare profession under the Osteopaths Act of 1993. British osteopaths complete training focused on manual therapy for musculoskeletal conditions. They cannot prescribe medications or perform surgery. The General Osteopathic Council oversees their practice, and the profession sits alongside physiotherapy and chiropractic rather than medicine.
In many European countries, the picture is different again. Osteopathic physicians in Europe are typically MDs who completed postgraduate training in osteopathic techniques as a specialization. Because they already hold a full medical degree, they retain all the practice rights of any other physician in the European Union.
So the answer to “is an osteopath a doctor?” depends entirely on where you are. In the U.S., a DO is unambiguously a physician with the same legal authority, training pipeline, and clinical outcomes as an MD. In the UK and parts of Europe, the term “osteopath” may refer to a manual therapist with a narrower scope of practice and no prescribing rights. If you’re choosing a healthcare provider, the credential after their name and the country they’re licensed in will tell you exactly what kind of training and authority they have.
