Geneticists and genetic counselors both work with your genes and your family’s health, but they do different jobs. A clinical geneticist is a doctor who examines you, makes the diagnosis, and plans treatment. A genetic counselor holds a master’s degree rather than a medical degree, and gathers your family history, explains testing and results, and helps you decide what to do next. The two roles are built to work side by side, so a genetics visit often means seeing both.
What Each Professional Actually Does
A clinical geneticist is a medical doctor who identifies and manages genetic conditions, and who can prescribe medicine and treat patients.1CheckRare. The Difference Between a Geneticist and a Genetic Counselor They read through your symptoms, do a full physical exam, weigh the possible diagnoses, and decide what testing comes next.2PubMed Central. Genetic counseling and the role of genetic counselors in the United States Once a diagnosis is made, they build the treatment plan and bring in whichever other specialists the condition calls for.3PubMed Central. Genetic counseling and the role of genetic counselors in the United States
A genetic counselor typically holds a master’s degree in genetic counseling, not a medical degree.4CheckRare. The Difference Between a Geneticist and a Genetic Counselor Their part of the visit is your medical and family history, plus a frank talk about what a test can and can’t tell you.5Genetics in Medicine. A novel approach in pediatric telegenetic services: geneticist, pediatrician and genetic counselor team After a diagnosis, the counselor often explains the findings to you, including what they mean for your relatives.6PubMed Central. Genetic counseling and the role of genetic counselors in the United States Core counselor skills include communication, critical thinking, and judging how you and your family are coping emotionally.7PubMed.

The family history session is where much of the counselor’s work happens. They ask about three generations of relatives, including which conditions each person had and how old they were when it was diagnosed. They also ask about miscarriages, early deaths, and ethnic background, because patterns in these can point toward particular inherited conditions. The resulting family tree shapes which test makes sense and whether a result is likely to matter for you. Answers like “heart trouble” or “a growth” are too vague to use, so the counselor will often ask you to find out the specific diagnosis.
The geneticist’s exam looks at physical features such as body proportions, skin, eyes, hands, and growth, because some genetic conditions show up as patterns of small signs. Height, head size, and arm span are measured and compared with what’s expected for age. The exam may turn up something you hadn’t connected to your main concern, and that can redirect which test is chosen. A normal exam doesn’t rule out a genetic condition, but it helps narrow what to test for.
Which One Should You See
A counselor fits when your question is about family risk, whether to test, or what a result means. When someone has unexplained symptoms, such as a child with developmental delays, the physical exam and diagnosis need a geneticist.8PubMed Central. Genetic counseling and the role of genetic counselors in the United States Counselors also specialize, in areas such as pregnancy, children’s health, cancer, neurology, eye disease, and psychiatry.9National Society of Genetic Counselors. Geneticist vs. Genetic Counselor: What’s the Difference?
Some common situations and the usual first stop:
- Strong family history of breast or colon cancer: a cancer genetic counselor.
- Abnormal prenatal screen: a prenatal counselor.
- Child with unusual features or delays: a geneticist, often with a counselor.
- Adult with a known family condition like Huntington’s: a counselor first, for testing decisions.
Some situations call for both, and a clinic that sees you with both professionals handles that without you having to choose. A wrong first stop is usually fixable, since the two can bring each other in.
A specialty counselor can matter. One who works in cancer genetics knows which gene panels fit which cancers and how results change screening schedules. A prenatal counselor is used to explaining screening results under time pressure and talking through options during pregnancy. A general genetics clinic may serve many kinds of patients, so asking about the counselor’s focus helps. If no counselor nearby covers your specialty, a general one can still help and may consult a specialist colleague.
When booking, ask whether the clinic sees you with a counselor, a geneticist, or both, and which specialty the counselor covers. Ask whether the visit can be by video. Bring any prior test reports and your relatives’ diagnoses.
How the Two Work Together at a Visit
In team clinics, a doctor or nurse practitioner may consult the geneticist while the counselor gathers your family history, and together they form your plan.10PubMed Central. Single center experience developing sustainable genetics clinical care: a model to address workforce challenges in medical genetics Dividing the work this way is meant to improve your visit and lower the chance of medical errors.11PubMed Central. Single center experience developing sustainable genetics clinical care: a model to address workforce challenges in medical genetics In one children’s telehealth model, a pediatrician examines the child, the counselor handles history and the testing talk, and the geneticist supervises and advises.12Genetics in Medicine. A novel approach in pediatric telegenetic services: geneticist, pediatrician and genetic counselor team Visits expected to be simple often turned out more complex, so most needed counselor and physician input after all.13PubMed Central. Single center experience developing sustainable genetics clinical care: a model to address workforce challenges in medical genetics
A typical team visit starts with intake and the family tree, done with the counselor. The counselor’s early work gives the geneticist a ready summary, so the exam can focus on physical findings and you aren’t repeating yourself to several people. Next comes the exam, by the geneticist or another clinician. Then both professionals join you to discuss testing options and consent. A later results visit is often led by the counselor, with treatment steps coming from the doctor.
You might not see the geneticist in person. There are few geneticists, so they often supervise rather than see every patient. Seeing a nurse practitioner or counselor doesn’t mean lesser care, and you can ask to speak with the geneticist if a question needs a doctor.
The results visit explains what was found and what it means for your health now. The counselor usually covers what it means for relatives, including who might want testing. If treatment or monitoring is needed, the doctor lays out those steps, often with referrals to other specialists. Bringing someone along helps, since taking in results is easier with a second person to listen and remember.
Training and Credentials
Geneticists first earn an MD or DO, then complete a medical genetics residency, often three years.14National Institutes of Health. Graduate Medical Education: Medical Genetics and Genomics Residency That training covers children and adults with chromosome, metabolic, and developmental conditions.15PubMed. Medical Genetics and Genomics Residency Programs Geneticists can be board-certified in clinical genetics, laboratory genetics, or biochemical genetics.16ABMGG. Specialties & Subspecialties Counselors complete an accredited master’s program that blends medical genetics, ethics, and counseling theory.17Icahn School of Medicine. Master of Science in Genetic Counseling They then take the American Board of Genetic Counseling exam to become certified.18ASU Degree Search. Genetic Counseling Degree, MS | ASU
Licensing varies by place. Only 28 US states license genetic counselors, though most others are working toward it.19PubMed Central. Impact of the Access to Genetic Counselor Services Act In Europe the counselor role began around 1980 and still isn’t recognized in every country.20PubMed Central. The role of the Genetic Counsellor in the multidisciplinary team: the perception of geneticists in Europe
Board certification shows the doctor passed an exam beyond residency. A geneticist’s training lets them recognize a pattern of symptoms that other doctors might see as unrelated problems.
The counselor’s master’s program includes supervised clinical rotations, so they’ve practiced real sessions before certifying. Studying ethics prepares them for hard questions, such as testing children or sharing results with relatives. Certification isn’t a one-time event: counselors must keep up with continuing education, which keeps them current on testing that changes quickly.
To check credentials, look for “MD, FACMG” or board certification for geneticists, and “MS, CGC” for certified counselors. In licensing states, you can verify a counselor’s license online.
Insurance and Cost
Medicare pays for genetic counseling when a physician, nurse practitioner, or physician assistant bills it.21PubMed Central. Impact of the Access to Genetic Counselor Services Act It does not pay when a genetic counselor provides it, because it doesn’t recognize counselors as providers.22PubMed Central. Impact of the Access to Genetic Counselor Services Act Proposed federal legislation would pay counselors 85% of the physician rate.23PubMed Central. Impact of the Access to Genetic Counselor Services Act For now, on Medicare, your counseling may be billed under a doctor’s name.
The rule is about who bills, not whether counseling is valuable. Some clinics work around it by having a physician or nurse practitioner bill the visit, though how they do this varies. Ask the clinic directly how it handles Medicare patients before you book. If you have a Medicare Advantage or supplemental plan, its rules may differ, so check those too.
Before the appointment, call your insurer about coverage for both genetic counseling and the test itself. Ask the clinic how it bills counselor visits and whether testing needs prior approval. Private plans often cover counselor visits even when Medicare doesn’t.
Asking early pays off. Counseling and the test are often billed separately, so one can be covered while the other isn’t. Some insurers want to approve testing in advance, and skipping that step can leave you with the full bill. Coverage often depends on meeting criteria, such as a certain family history, so your history may decide whether a test is paid for. Ask for the answer in writing, or note the name of the person you spoke with.
Getting an Appointment and Using Telehealth
About a third of clinical geneticists see patients by telemedicine.24PubMed Central. The 2019 US medical genetics workforce: a focus on clinical genetics In one regional survey, 56% of genetics telehealth programs had waits under two weeks.25PubMed. Clinical models of telehealth in genetics: A regional telegenetics landscape In that survey, 59% could hold video visits in patients’ own homes, and half reached people over 200 miles away.26PubMed. Clinical models of telehealth in genetics: A regional telegenetics landscape
Video works well for history-taking, explaining test options, and reviewing results, because all of these rely on conversation. Ordering a test often involves a saliva kit or a blood draw at a local lab, which the clinic arranges. Video also makes it easier to include relatives in other places, who can join the call and hear the information directly. You can share your screen or have documents ready to look at together.
To prepare, gather relatives’ diagnoses and their ages at diagnosis, and have prior reports ready to share. Asking your doctor for a referral can speed scheduling.
If your question depends on a physical exam, such as looking for particular features, a video call may not be enough. A clinic may start with video and then ask you to come in once the history suggests an exam is needed. Ask at booking whether the visit type fits your question so you don’t lose time.
What to Do With Home DNA Test Results
Raw DNA data should be interpreted by people trained in classifying genetic variants with validated tools.27NSGC. Raw Data So review results with a genetics specialist, usually a counselor, before acting on them.28NSGC. Raw Data Then confirm any health-relevant finding in a CLIA-certified, CAP-accredited lab, meaning one that meets federal clinical standards.29NSGC. Raw Data
Third-party apps can mislead. Consumer chips can mislabel rare variants, and a scary app report may prove false on clinical testing. A clean report doesn’t rule out risk either. Don’t change medications or schedule surgery on raw data alone.
These kits look at selected spots in your DNA rather than reading your whole genome carefully. A company health report is a screening-level result, while a clinical test is designed to be accurate enough to act on.
For the visit, bring the company’s report and, if you have it, the raw data file, so the counselor can see exactly what was found. Bring your family history notes, since they change how seriously a finding should be taken. Write down what led you to test and what you’re worried about, so the visit answers your actual question.
Your Privacy and Your Relatives
Under US privacy law, providers must tell you a condition runs in families and that relatives should know.30PubMed. Reconsidering the duty to warn genetically at-risk relatives They are neither required nor allowed to contact relatives without your consent.31PubMed. Reconsidering the duty to warn genetically at-risk relatives For counselors, whether disclosure is ever permitted is less clear and may depend on the state.32PubMed Central. Legal Challenges in Genetics, Including Duty to Warn and Genetic Discrimination
Your results are part of your medical record, and the clinic can’t hand them to relatives or your employer. The work of telling family falls to you.
The team can help with that work. Counselors can write a family letter explaining the result and suggest which relatives most need testing. They also help you plan how to raise it with relatives who may be upset, and they’re trained to support your decision rather than push one.
