Can I tell ChatGPT directly that information about my practice is wrong?

AI providers don't offer a correction feature for practices. Rating an answer in the chat helps the provider in general but doesn't specifically change what is said about your practice. The only effective approach is to correct the sources the AI reads from: your website, Google profile, Bing, portals and directories.

How long does it take for a correction to reach ChatGPT?

There is no exact answer. Answers that use web search draw on current sources and often change within days to weeks. What a model knows from its training only changes with a new model version. So check again with the same questions after four weeks.

How often should I check what ChatGPT says about my practice?

Once a quarter with the same five questions, and also after every change to your address, opening hours, team or services. Only by keeping the questions the same can you see whether something has improved or got worse.

Can MedDirection carry out the check for my practice?

Yes. Using professional tools, we evaluate many patient questions across several weeks and AI systems, find the sources of incorrect information and correct them. The free AI visibility check gives you a first impression.

Why does ChatGPT give the wrong address for my practice?

Usually the old address is still listed somewhere online: in a directory, on a portal, in an old press article or in a second Google profile. The AI repeats what it finds. Search for your practice name with the old street and correct every result you can change yourself.

ChatGPT shows wrong info about your practice? How to fix it

Patients ask AI assistants about practices, and the answers aren't always right. You can't correct this inside the AI, only through the sources it reads from.

More and more patients no longer just ask Google, but ChatGPT, Perplexity or Gemini: ‘Which dentist in Dresden treats anxious patients?’ or ‘Is Dr Muster's practice open on Saturdays?’ The answer sounds confident, even when it is wrong. For a practice, this means a patient gets false information about you, and you never find out.

Typical errors

Outdated opening hours

often from a directory that was never updated

Old address

after a move, from portals or old articles

Wrong services

treatments the practice never offered or no longer offers

Wrong insurance status

a private practice listed as accepting statutory health insurance (GKV), or the other way round

Former doctors

still listed, while new ones are missing

Mix-ups

with a practice of a similar name in the same town

Why AI gets it wrong

AI hallucination: A false statement that an AI assistant phrases convincingly. It arises when the information online is contradictory, outdated or incomplete.

AI assistants rarely make things up out of nothing. Usually they repeat what is written somewhere, or fill a gap with the most likely answer. If your website shows the practice's new address but a directory still has the old one, the AI has to decide, and it doesn't always decide correctly. On top of that, what a model knows from its training can be months old. Only what it looks up live online when asked is current.

Which leads to the most important sentence in this article: you can't correct an AI answer inside the AI, only through its sources.

Five test questions for your practice

Test question	What it shows
‘Which dental practice in [town] specialises in [treatment]?’	whether you are named for your speciality
‘When is the [name] practice in [town] open?’	whether opening hours and address are correct
‘Does the [name] practice accept patients with statutory health insurance?’	whether your insurance status is correct
‘Which doctors work at the [name] practice?’	whether the team is up to date
‘What do patients say about the [name] practice?’	how reviews are summarised

Quick tip

Ask the questions in a window where you are not logged in, or in a new chat. Otherwise your earlier questions influence the result, and the answer looks different for you than for your patients.

A spot check is a good start, but not yet a verdict: the same question can be answered differently today than tomorrow. For a reliable assessment, we work with professional tools that evaluate many patient questions across several weeks and several AI systems, and with experience from many practice projects of which deviations really matter.

How to correct the sources

Error, source and fix

Error	Likely source	What to do
Opening hours, phone	Google Business Profile, Bing Places, directories	keep them identical everywhere, add special opening hours
Old address	Portals, directories, old articles	search for the practice name plus the old street, have the entries changed
Wrong services	your own website, portals	one page per treatment offered, delete outdated content
Insurance status	Portals, website	state it clearly on the home page and in your profile
Former doctors	Team page, portals	update the team page, have former doctors' portal profiles removed
Mix-ups	similar name, missing details	full name, address and specialty on every page, structured data

The greatest impact comes from the sources AI systems read most often: your own website, your Google Business Profile, Bing Places and the major doctor portals. How to get these entries in order is explained in the article Getting found better on Google. If reviews are summarised incorrectly, the article Deleting Google reviews will help.

Cleaning up is painstaking work: lots of entries, each with its own login and its own process. If you don't have the time in your day-to-day practice, or want it done faster, we will take care of it for you, from tracking down the wrong source to checking that the correction has reached the answers.

Caution

Don't try to influence the AI with hidden text or instructions on your website, such as white text on a white background. Google treats hidden text as deception, and tricks like these damage trust in your site more than they help.

What doesn't help

Rating or commenting on the answer in the chat. This helps the provider in general but doesn't specifically change what is said about your practice.
Checking once and ticking it off. Answers change with every model and every new source. Check regularly with the same questions.
Only changing your website. If the old information is still listed in three directories, it will still appear in the answer.

What is out of your hands

No one can guarantee that an AI answer is correct or that a practice will be named. Answers depend on the question, location, chat history and model.

What a model knows from its training cannot be changed retrospectively. It only becomes current with a new model version.

Conclusion and outlook

AI assistants say about your practice whatever they find online. If something there is wrong, it ends up in the answer too, and you only find out if you ask yourself. The good news: most errors can be traced back to a few sources and fixed there. Keeping your website, Google profile, Bing Places and portals consistent removes the most common causes in one go.

The outlook: checking your AI answers will become as routine as maintaining your Google profile. In future, AI assistants will not only describe practices but compare them and request appointments on behalf of patients. On top of that come ads in AI answers, which OpenAI is currently testing in ChatGPT. The more decisions are made within the answer, the more important it is that it is accurate about your practice. So make the check a fixed routine, for example once a quarter, or hand it over to us.
