Some nurse practitioners are called “doctors” because they hold a Doctor of Nursing Practice (DNP) degree, a doctoral-level credential in nursing. This is an academic title, not a medical one, and the distinction matters more than you might expect. The use of “doctor” by nurse practitioners has sparked legal battles, new state laws, and a broader debate about what patients actually understand when they hear the word in a clinical setting.
The DNP Degree, Explained
In 2004, nursing schools affiliated with the American Association of Colleges of Nursing voted to move the standard preparation for advanced nursing practice from a master’s degree to a doctorate. The result was the Doctor of Nursing Practice, a clinical doctorate focused on applying research to patient care rather than conducting original laboratory or bench science. It is distinct from a PhD in nursing, which is a research degree.
The push toward doctoral-level training has only accelerated. In 2018, the National Organization of Nurse Practitioner Faculties called for the DNP to become the entry-level degree for all new nurse practitioners by 2025, and it reaffirmed that position as recently as April 2023. Not every NP program has made the switch yet, so many practicing nurse practitioners still hold master’s degrees. But DNP programs have grown rapidly, and the trajectory is clear: nursing’s leadership wants the doctorate to be the baseline credential.
A DNP program typically requires about three to four years of post-baccalaureate study, including extensive clinical hours. Graduates earn the right to use “Dr.” as an academic prefix, just as holders of PhDs, Doctor of Psychology degrees, or Doctor of Pharmacy degrees do. The title reflects the level of education completed, not a license to practice medicine.
Why This Creates Confusion
In everyday life, most people associate the word “doctor” with a physician. When a nurse practitioner introduces themselves as “Dr. Smith” in a clinic or hospital, many patients assume they are seeing a medical doctor. AMA survey research found that 39% of patients incorrectly believe a person holding a Doctor of Nursing Practice degree is a physician. A separate finding from the same research showed that 45% of adults said it was not easy to identify who is or is not a licensed medical doctor based on titles, credentials, and advertising materials alone.
This confusion is not trivial. Nurse practitioners and physicians follow different training paths, have different clinical hour requirements, and in many states operate under different levels of oversight. A patient who believes they are seeing a physician may have different expectations about the depth of diagnostic training behind their care. The gap between what “doctor” means academically and what it signals to a patient sitting on an exam table is at the heart of the controversy.
State Laws on Using the Title
Whether a nurse practitioner can legally call themselves “doctor” in a clinical setting depends entirely on where they practice. There is no single federal rule, and states have taken sharply different approaches.
California has some of the strictest rules. The state’s Business and Professions Code prohibits most healthcare professionals other than physicians from calling themselves “doctor” in a clinical context. In 2022, a San Luis Obispo County nurse practitioner named Sarah Erny was ordered to pay $19,750 in civil penalties for advertising herself as “doctor” in her medical practice. The settlement required her to stop using the title when providing care and to correct internet listings that referred to her as “Dr.”
Georgia took a middle path with its Healthcare Practitioners Truth and Transparency Act. Under that law, a nurse practitioner who holds a doctorate can use the title “doctor” in a clinical setting, but must verbally clarify during each patient interaction that they are not a medical doctor or physician. The law also bars non-physician practitioners from using medical specialty titles in advertisements. Violations can trigger disciplinary action from the practitioner’s licensing board.
Other states are more permissive, allowing DNP-holding nurse practitioners to use the title with fewer restrictions. The patchwork means that the same credential can carry different rules depending on which side of a state line you’re on.
The AMA’s Position
The American Medical Association has been the most vocal opponent of non-physicians using the “doctor” title in healthcare settings. Its “Truth in Advertising” campaign argues that when multiple types of healthcare professionals use the same title, patients lose the ability to distinguish between them. The organization pushes for legislation requiring all healthcare professionals to clearly identify their license type in advertisements, websites, and patient communications. It also supports laws mandating that clinicians wear name tags specifying their credentials during patient encounters.
The AMA points to its own survey data showing that 91% of respondents strongly prefer a healthcare team led by a physician. Critics of the AMA’s stance counter that these campaigns are partly about protecting physician market share, especially as nurse practitioners gain independent practice authority in more states. Currently, 20 states and territories allow nurse practitioners to practice and prescribe with no physician oversight at all.
What Nurse Practitioners Say
Nursing organizations argue that the “doctor” title is earned through rigorous doctoral education and should be available to anyone who completes that level of training. They point out that other professions use it without controversy: pharmacists with a PharmD, physical therapists with a DPT, and psychologists with a PsyD all use “Dr.” in professional settings. From this perspective, restricting the title to physicians alone undervalues the doctoral training that other clinicians complete.
Many nurse practitioners who hold DNPs navigate the issue by using the title in academic or professional contexts but not in direct patient care, or by immediately clarifying their role. The debate is less about whether the degree is legitimate and more about whether the clinical setting changes what the title communicates.
How to Know Who’s Treating You
If you’re unsure whether the person providing your care is a physician or a nurse practitioner, you can simply ask. In states with transparency laws, your provider may be required to tell you. Beyond that, look for credentials after a name: MD or DO indicates a physician, while DNP, APRN, or NP indicates a nurse practitioner. Office paperwork, intake forms, and clinic websites often list the full credentials of each provider on staff.
The letters after the name will always tell you more than the title before it.
