Referrals and Coordination With Primary Care and Specialists
How to keep your doctors and any naturopathic or integrative practitioner informed, what to share, why people often do not disclose, and how referrals can work in both directions.

Why coordination matters
Different clinicians may not know what the others have recommended. That matters because some complementary approaches can have an effect on conventional medicine, as NCCIH puts it. [3] In cancer care, a systematic review of 21 studies found 20% to 77% of patients using complementary medicine did not tell their doctors, most often because the doctor did not ask, or the patient expected disapproval or thought it irrelevant. [4] A 2023 review of 30 articles (8,721 participants) found nondisclosure common and warned that the lack of dialogue raises the risk of adverse interactions with conventional cancer treatments. [5] Those reviews focused on cancer, and many included studies were small and from one center or region, so findings may not apply to every setting. [5]What to share, and with whom
NCCIH's advice for patients:- List every complementary practice you use on your patient history form. [3]
- Tell your providers at each visit, including over-the-counter medicines, prescriptions, and dietary and herbal supplements. [3]
- Do not wait to be asked. [3]
- Tell all your providers about the complementary approaches you use and about all practitioners treating you. [6]
| Who | What they can usefully know |
|---|---|
| Primary care clinician | All supplements, herbs, special diets, fasting programs, tests you have had, and treatments planned |
| Specialist (for example cardiology, oncology, endocrinology) | Anything that could affect your medicines or procedures, and anything a practitioner has told you to stop or start |
| Pharmacist | Every product you take, including herbal medicines; the NHS advises checking with a pharmacist before taking a herbal medicine if you already take other medicine. [2] |
| Naturopathic or integrative practitioner | Your diagnoses, medicines, recent test results and who else treats you |

How referrals can work in each direction
- From your doctor to a practitioner. NCCIH suggests first asking your doctor or other health care provider for names of practitioners in your area; a nearby hospital or medical school, professional organizations, state regulatory agencies or licensing boards may also help. [6] We do not list or recommend practitioners.
- From a practitioner to conventional care. NCCIH says naturopathic practitioners may, if appropriate, refer patients to conventional health care providers. [7] Ask early how a practitioner decides when to refer, and what they do if tests or symptoms need urgent attention.
- Between clinicians. NCCIH advises finding out whether the practitioner is willing to work together with your conventional health care providers. [6] Ask whether they will share notes or test results if you give permission.
What scope and title differences mean for coordination
Titles and licensing differ by place. NCCIH says licensed naturopathic doctors can diagnose, which may include history, exams, lab tests and imaging, while traditional naturopaths are not eligible for licensing. [7] The scope of practice varies by state. [7] In the US there is no standardized national system for credentialing complementary health practitioners. [8] In England, the NHS says other complementary therapists and herbal medicine practitioners do not need to be registered by law, and suggests choosing one registered with a professional organization accredited by the Professional Standards Authority. [2] A license or certificate is not a guarantee of being qualified. [8] Details by place are in how to verify a credential and scope of practice.Cost and insurance
NCCIH advises not assuming that insurance covers a practitioner's services; contact your insurer and ask. [6] Ask whether tests ordered by a practitioner will be reviewed by your doctor, and who pays for repeat testing. See costs, packages and supplement sales.Frequently asked questions
Should I tell my doctor about supplements and herbs?
Yes. NCCIH advises telling every provider about complementary approaches you use, including supplements, because some can affect conventional medicine. [3]
Why do people not tell their doctors?
In cancer care reviews, main reasons included the doctor not asking and the patient expecting disapproval or thinking it irrelevant. [4]
Will a naturopathic doctor refer me to my doctor?
NCCIH says naturopathic practitioners may refer patients to conventional providers if appropriate. [7] Ask the practitioner how they decide.
How do I find a practitioner who will cooperate with my doctor?
Ask your doctor, hospital, professional organizations or licensing boards for names, and ask the practitioner if they will work with your other providers. [6]
Can I use a practitioner's advice instead of my specialist's?
Do not replace or stop prescribed treatment without talking to your doctor. [2]
