Clinical systems · Visual clinical decision support
VisualDx
VisualDx is a clinical decision support tool founded in 1999 in Rochester, New York, that helps clinicians diagnose skin and other visible conditions by comparing a patient with more than 50,000 curated medical images across all skin tones.
Strong fit
- Primary care, urgent care, and emergency clinicians who see rashes and skin lesions without a dermatologist nearby
- Health systems that want to cut avoidable dermatology referrals and long specialist waits
- Clinicians who want images of disease on darker skin tones
Weak fit
- Dermatologists who already recognize most presentations on sight
- Clinicians who want a general chat-style answer engine for any medical question
- Teams that need a tool for imaging such as X-rays or CT scans
Bottom line
VisualDx gives clinicians a searchable atlas of more than 50,000 medical images and a differential diagnosis builder for rashes, lesions, and other visible findings. It is worth having for primary care, urgent care, and emergency teams, where a quick visual comparison can avoid a needless transfer or referral. It supports clinical judgment and works best alongside a dermatology referral path.

VisualDx is used by primary care doctors, nurse practitioners, urgent care and emergency clinicians, and students who need help with conditions they can see, such as rashes, skin lesions, and eye and mouth findings. A clinician enters findings such as the patient's symptoms, the lesion type, and where it appears, and VisualDx builds a differential diagnosis with matching images and treatment notes. The hospital and health system page says the library holds more than 50,000 curated images across all skin tones and connects to Epic, Cerner, and other EHRs with single sign-on.
On price, VisualDx is one of the few clinical decision support tools with a public price for individuals. The pricing page lists Core at $249.99 a year or $39.99 a month, and Elite, which adds CME credit and patient handouts, at $299.99 a year or $49.99 a month. Small groups of 2 to 5 users can buy directly, and health systems license it for all their clinicians. Its competitors are text-based tools such as UpToDate and AI answer engines HIR has reviewed, including OpenEvidence, Vera Health, and Glass Health, none of which is built around a picture-first diagnosis workflow.
Dermatologist Art Papier co-founded the company in 1999 and is still its CEO. Its history page says the first product shipped on CD-ROM in March 2001 to help with fever-and-rash workups, and the company supported the CDC after September 11. It added an iPhone app in 2008, EHR links through HL7 infobutton and SMART on FHIR in 2012, general medicine content in 2016, the DermExpert image AI in 2017, and an API in 2021. VisualDx does not publish revenue. Its revenue is an estimated $15 million a year, based on third-party estimates for a company of about 100 to 125 employees.
Physicians quoted by VisualDx say it has helped them avoid a transfer to a tertiary care center and skip unnecessary dermatology referrals. Papier has described the product's AI as a way to help doctors "organise their thinking around possibilities," in a PLOS interview, and not as an engine that hands back one answer. The tool is less useful for clinicians who already see a lot of skin disease, and its image AI depends on a good photo.
What clinicians say
What people like
"VisualDx helped me determine it was unlikely to be a dangerous rash, preventing a costly and cumbersome transfer to a tertiary care center." VisualDx
"I have been able to avoid unnecessary dermatology referrals because of the detailed images and information in VisualDx." VisualDx
What people don't like
"It is great for a rash, but for anything that is not visible I still go to my usual reference, so it is a second subscription."
"The individual plan is fair, but CME and patient handouts are only on the higher Elite tier."
