✅ About this Course
From our review of VisualDx:
This AI-enhanced clinical decision support system (CDSS) helps you build custom differentials on the fly, especially when your patient’s symptoms are vague, their rash is, well…rashy, or your coffee hasn’t kicked in yet. VisualDx is built to support real-time clinical decisions with thousands of high quality medical images, peer-reviewed content, and genuinely useful tools and features that work well on iOS, Android, and desktop. It is one medical app that I personally think is a must-have for all practicing clinicians.
What is VisualDx
What started as a modest dermatology reference has grown into the world’s largest medical image library, encompassing just about every medical specialty, from emergency medicine to psychiatry (and of course, still dermatology).
I’ve been using VisualDx for a few years now and originally wrote this review in 2020. It’s been updated every so often, with the next major update published this year in 2025.
At its core, VisualDx helps you build better differential diagnoses, learn more about specific diagnoses, and keep up with your CME requirements. You know how they say a picture is worth a thousand words? Well, VisualDx takes that concept to the next level. See for yourself.
1. Build a Differential Diagnosis in Seconds
One of the main strengths of VisualDx is its ability to help you construct a high-quality differential diagnosis based on the specific clinical facts of your case. You start by entering a Chief Complaint or selecting a Quick Start option: Dermatology (all skin types or skin of color), Ophthalmology, ENT/Oral Medicine, and Drug Reactions. Next, select your patient characteristics.
2. Diagnosis Lookup
Sometimes you don’t need to build a differential. You just need to confirm what you are already thinking, rule out zebras, or quickly review a condition you haven’t seen since the boards.
We’ve all done a quick (sometimes covert) online search before seeing a patient with something like Leriche syndrome listed on their medical history.
Each condition (even Leriche syndrome) has an accompanying visual representation – called the Sympticon (clever, no?) – to provide a brief summary of the condition.
It also comes with a concise, no-frills, action-points-only summary of the condition. Synopsis, differential, workup, maybe a couple of pearls, treatment, boom. Done. Perfect for the busy clinic or on rounds. Here’s what the search and results sections look like on both mobile and desktop.
3. Earn CME While You Practice (really)
One of the most understated features of VisualDx is that it gives you Category 1 CME credit just for using it. Every time you look up a diagnosis or build a differential, you’re earning. No webinars, no hour-long videos, no post-test trauma.
Each qualifying search, differential built, or skin lesion analyzed earns 0.5 AMA PRA Category 1 Credits™, and your progress tracks automatically in your account. To officially claim your CME, just answer two quick questions per activity, hit “Submit,” and download your certificate. That’s it. I racked up several credits just researching and updating this review, and like to think I’m correspondingly smarter for it.
If you’ve ever found yourself panic-hunting for CME before your renewal deadline or CME stipend expires, VisualDx makes it ridiculously easy to stockpile credits while doing what you're already doing: taking care of patients and looking stuff up.
