I asked ChatGPT to recommend a primary care doctor in Nashville. Same prompt, several times. The name that kept surfacing wasn't the practice with the biggest ad budget or a hospital chain. It was Dr. Burton Sanders, an independent, board-certified family physician who has been in practice more than 30 years and holds a spot on Healthgrades' Honor Roll with a 4.9 average. The question worth answering is not who it named, but why, because the reason is something almost any practice can copy. ChatGPT built the answer from a short list of sources most doctors underuse: healthcare directories (Zocdoc, Healthgrades, and Vitals), the credential checks it trusts for health questions (ABMS Certification Matters and the government's NPI registry), and peer "top doctor" lists like Castle Connolly's.
AI answers vary run to run. We ran this prompt in ChatGPT several times in July 2026 and tracked the names that consistently surfaced, so treat the doctors below as a snapshot, not a fixed ranking.
This is the new reality for practices that spent years getting good at Google. ChatGPT is building a separate recommendation system, and the doctors winning there are not always the ones winning on Google. Health is also a topic where a wrong answer can hurt someone, so ChatGPT leans hard on credentials and trusted directories, far more than on review counts. This article shows why ChatGPT keeps landing on doctors like these, the one move most miss, and what to do about it. It is part of our guide to getting recommended by AI, across dozens of categories.
Why ChatGPT Keeps Landing on It
Dr. Sanders did not get there by accident. He sits on top of the strongest signal in health, and two other real Nashville doctors show the other two levers ChatGPT rewards. Together they are the three things that decide a doctor recommendation.
Dr. Burton Sanders is verifiable, complete, and accepting new patients everywhere ChatGPT looks. He is board certified by the American Board of Family Medicine, his identity and specialty are on file in the federal NPI registry, he carries a 4.9 on Healthgrades' Honor Roll, and his Zocdoc profile says he is accepting new patients and offers telehealth. When ChatGPT runs a health query, it wants a name it can confirm is a real, board-certified physician who is taking patients, and Dr. Sanders checks out on every source it reads. The takeaway: for a doctor, ChatGPT trusts agreement across independent sources it can verify, not the size of your marketing. A complete, board-certified, accepting-new-patients profile on Zocdoc and Healthgrades is worth more than any ad budget.
Dr. David Heusinkveld owns the peer recognition ChatGPT quotes. He is a board-certified internist at Midstate Internal Medicine, a Vanderbilt-trained MD, and a Castle Connolly Top Doctor for ten years running. Castle Connolly is peer-nominated, roughly the top 7% of physicians, all board certified, so when ChatGPT answers a "top" or "best doctor" question it treats that nomination as real authority instead of a consumer star count. The takeaway: a spot on a peer or editorial "top doctors" list is worth more than any amount of your own marketing, because ChatGPT is quoting a source that is not you. No Castle Connolly nod in your market? Your regional magazine's or local paper's "top doctors" roundup does the same job.
Dr. Corey Batson wins the highest-intent search of all, "takes my insurance and taking new patients." He is a board-certified family physician at Salient Health Primary Care and Vanderbilt faculty, with a complete Zocdoc profile that is accepting new patients, offers video visits, and can be filtered by insurance (Aetna, Blue Cross Blue Shield, Cigna, Medicare, and more), with appointments often open within a week. When a patient asks for a doctor who "takes Blue Cross and is accepting new patients," that insurance-filtered profile is the exact thing ChatGPT pulls. And that points to the biggest opportunity in the category, one almost no practice uses on purpose.
One more thing worth naming: the community threads that decide home-services recommendations barely surface here. Searches for Reddit primary-care recommendations turn up little of substance, so for a health question ChatGPT leans on credential checks and directories, not forum chatter.
The One Move Almost No Practice Makes
Here is the move, and it is close to free: make your board certification independently verifiable, then mirror it, your insurance list, and your accepting-new-patients status on your Zocdoc and Healthgrades profiles. For a health question ChatGPT will not recommend a name it cannot confirm is board certified, and it answers "takes my insurance" from the directory profile, not from your website. So the two facts that decide the recommendation, "is this a real board-certified doctor" and "does she take my plan and is she taking patients," get settled on pages you may not have checked in years.
Do this Monday: Open ABMS Certification Matters (certificationmatters.org), the free, no-login board-certification lookup, and confirm your certification appears and is current. Then open your Zocdoc and Healthgrades profiles and confirm each one states your board certification, degree (MD or DO), specialty, every insurance plan you take, and that you are accepting new patients. If ChatGPT cannot verify your certification, or your profile does not list the plan a patient filtered by, you lose the patient, even if your own site says you take it. Most practices have never checked this once. It costs nothing and it decides the searches that turn into booked appointments.
How ChatGPT Actually Builds the Answer
ChatGPT has no private list of good doctors. It reads your question, breaks it into smaller, more specific searches, runs those on Google and Bing, and builds an answer from the pages that come back. A patient rarely types a single keyword. They type a full sentence with conditions, something like "recommend a good primary care doctor near me who's accepting new patients and takes my insurance." ChatGPT turns that one prompt into a set of smaller searches and runs each on its own:
- best primary care doctor near me accepting new patients
- primary care doctor that takes Blue Cross Blue Shield near me
- how to check if a doctor is board certified
- top doctors list for [city]
- family medicine vs internal medicine, which doctor do I need
- book a primary care appointment online same day near me
Every one of those lands on a city- or specialty-scoped page, plus a credential check, not a national ranking. There is no real "top doctors in America" list ChatGPT can quote for your city. The recommendation gets stitched together from the sources below.
| Source | Type | Why it shows up |
|---|---|---|
| Zocdoc | Booking directory + verified reviews | Top result for "accepting new patients." Only patients who booked can review, and you can filter by insurance, specialty, and same-day openings. This is the transactional layer for "takes my insurance." |
| Healthgrades | Healthcare directory + ratings | The largest US healthcare directory. Carries credentials, insurance, board-certification status, and a "% would recommend" score. This is the research-the-doctor layer ChatGPT names most in health answers. |
| Vitals | Patient-review site | Scores doctors on wait time, bedside manner, and getting the diagnosis right. ChatGPT uses it as a second opinion against Zocdoc and Healthgrades. |
| ABMS Certification Matters | Credential verification | Free, no-login lookup drawn from all 24 ABMS Member Boards. For a health question, this is the source ChatGPT trusts most to confirm a name is a real, board-certified physician. |
| CMS NPI Registry | Government provider record | The official federal record of every US provider's NPI number, specialty, and location. ChatGPT uses it to confirm a name is real and current. |
| Castle Connolly Top Doctors | Peer "best doctors" list | Doctors nominated by other doctors, roughly the top 7%, all board certified. ChatGPT quotes it for "top" and "best" questions because a peer nomination reads as authority, not a star count. |
Below these sit insurer provider finders (UnitedHealthcare, Blue Cross Blue Shield) and academic health-system "find a doctor" pages, both treated as the authority on who is in-network and taking patients. Community threads on Reddit and Nextdoor, which carry home-services recommendations, barely register for a health question, so treat them as a distant afterthought here, not the main event.
What Google Gets You vs. What ChatGPT Gets You
Google's top results for a doctor query are mostly big health-system pages and paid ads. ChatGPT rewards something different: showing up across the directories and credential checks above, verifiable as board certified, with your insurance and new-patient status current. The two overlap less than most owners assume. A physician can have 300 Google reviews and a polished health-system page and still be absent from a ChatGPT recommendation, because ChatGPT went to Zocdoc, Healthgrades, and Certification Matters to build its answer and the doctor was thin, unverified, or missing on all three.
None of this means your Google work was wasted. Ranking on Google is the entry ticket: if you don't rank at all, ChatGPT can't find you. It just isn't what decides the recommendation. What decides it is whether your credentials, insurance, and new-patient status are complete and verifiable on the sources ChatGPT actually reads.
What the Doctors That Show Up Share
The doctors ChatGPT names share three traits, all tied to the sources above, not to ad budget.
A complete, credential-first profile on the directories. A claimed Healthgrades and Zocdoc profile that states board certification, degree (MD or DO), specialty, every insurance accepted, and real appointment openings, with recent verified reviews, gives ChatGPT clear, current facts to work from. Sparse or unclaimed profiles get skipped.
Credentials it can verify. Doctors who name the specific marks, a board certification from an ABMS Member Board, an MD or DO degree, an active state license, and a hospital or academic-system affiliation, and who check out at Certification Matters and in the CMS NPI registry, get read as verified. On a health question ChatGPT looks for these before it will recommend a name.
Content that answers a specific patient question. Pages like "family medicine vs internal medicine, which do I need," "how to switch primary care doctors without losing your records," or "which insurance plans we accept" give ChatGPT a clear answer it can lift and quote. A site that only lists "Primary Care" and "Contact Us" gives it nothing to quote.
What the Invisible Doctors Lack
The doctors missing from ChatGPT's answers tend to be strong on Google and thin everywhere it actually looks.
Credentials no one can verify. Board certification, degree, and specialty aren't in plain text on a page ChatGPT can read, and can't be confirmed at Certification Matters or in the NPI registry. A careful health answer skips a name it can't verify.
No sign of which insurance they take. The site says "we accept most major plans," but the Zocdoc profile and the insurer's own provider finder don't list the doctor. For the biggest question a patient asks, "does this doctor take my insurance," ChatGPT follows the directory and the doctor never shows up.
A one-place footprint. Only a page inside the health system's site and a Google Business Profile. When ChatGPT looks to Zocdoc, Healthgrades, and Vitals for an independent, credential-first source, the doctor isn't there.
Generic website content. Pages titled "Services" and "Our Providers" with no answer to a specific question. Asked for "family medicine doctor accepting new patients in [city]," ChatGPT finds nothing to lift, so it names a doctor who wrote one.
What to Do
The fix runs across the same sources ChatGPT reads. None of it is technically hard, but it is specific to healthcare, not generic local marketing.
Make your credentials verifiable first. This is the Monday move above, and it is the highest-return thing on this list: confirm your board certification is current at ABMS Certification Matters, confirm your specialty and location in the CMS NPI registry, and state board certification, degree (MD or DO), specialty, and hospital affiliation in plain text on your bio page.
Complete all three directory roles, not just one. Build a full Zocdoc profile (with insurance and real openings), a complete Healthgrades listing, and a Vitals profile. Each does a different job, booking, research, and review cross-check, and ChatGPT reads across all three. Keep accepted insurers and "accepting new patients" current on each.
Confirm you're in-network in every insurer directory. Check that you appear correctly in the provider finders for the plans you take. This is the question that decides most primary-care searches, and it's one large health-system pages routinely get wrong for individual doctors. Practices that optimize for AI visibility in health win on this kind of specificity.
Publish patient-education pages. Write pages that answer the exact questions patients ask: "what does a family medicine doctor treat," "family medicine vs internal medicine," "how to find a primary care doctor accepting new patients in [your city]," and "which insurance plans we accept," dated with an "as of [month] [year]." Open each with a direct, 2-3 sentence answer that names your practice and specialty, then expand. That opening is the part ChatGPT quotes. Most practices leave it out, so the few that publish it get named again and again.
Go after peer and editorial recognition. Get nominated for Castle Connolly Top Doctors and pitch your local "top doctors" roundups. On a health question, a peer nomination carries more weight with ChatGPT than any number of consumer star ratings. In a smaller market, the local paper or a regional magazine's list is your version of Castle Connolly.
How Long It Takes
Directory and credential changes can move ChatGPT's recommendations within a few weeks, faster than most categories, because the credential and directory sources are already trusted and few practices complete them. Building the reviews and peer recognition that hold that recommendation takes a couple of months.
Weeks 1-4: Verify board certification at Certification Matters and your NPI in the CMS registry. Claim and complete Zocdoc, Healthgrades, and Vitals with insurance listed and "accepting new patients." Confirm you're in-network in your insurers' provider finders. Publish three to five patient-education pages.
Months 2-3: Start showing up for specific questions ("family medicine doctor accepting new patients [city]," "in-network primary care [neighborhood]"). Get 10 to 15 new verified reviews across Zocdoc, Healthgrades, and Vitals. Go after at least one peer or editorial listing.
Months 3-6: Build steady presence across your core specialty and location questions. Keep the profiles and accepted-insurer lists current, keep the reviews coming.
The window is open because most practices haven't started. Early movers face far less competition here than they do on Google.

Frequently Asked Questions
Does my Google rating affect whether ChatGPT recommends me?
Not directly. ChatGPT does not crawl Google Maps or read your star rating in real time. It runs your question as smaller searches on Google and Bing, then builds an answer from the pages that show up: Zocdoc and Healthgrades profiles, Certification Matters, the NPI registry, and Castle Connolly lists. Your Google rating only matters when one of those pages mentions it. What decides the recommendation is whether your credentials, insurance, and new-patient status are complete and verifiable on the sources ChatGPT actually reads.
Will patients actually find doctors through ChatGPT?
Increasingly, yes. For non-emergency decisions like choosing a new primary care doctor, more patients now ask ChatGPT "recommend a doctor near me who takes my insurance" instead of scrolling Google, and they get a direct answer built from healthcare directories and credential checks. Doctors who appear in those sources win patients who never see the Google listing at all.
Do board certifications help with ChatGPT recommendations?
Yes, and more than in almost any other category, because health is a topic where a wrong answer can hurt someone. But the certification has to be verifiable where ChatGPT checks: in plain text on your bio page, confirmed at ABMS Certification Matters, and consistent with the CMS NPI registry. Having the certification matters less than having it verifiable.
How does ChatGPT know which doctor accepts my insurance?
It reads the directory and the insurer's own provider finder, not your website. For "primary care doctor that takes Blue Cross near me," ChatGPT trusts your insurance-tagged Zocdoc profile and the insurer's in-network list over what your site claims. If you are in-network but not listed correctly there, the answer follows the directory and you get left out.
Can I pay for placement in ChatGPT's recommendations?
As of July 2026, no. ChatGPT does not offer paid placement inside its doctor recommendations. Visibility is earned through verifiable credentials, complete directory profiles, in-network verification, and reviews. Sponsored links can appear beside the answer, but the recommendation itself is built from the sources described above.
