For Dermatology Practices

    See more patients without hiring more staff.

    Dappledoc is an asynchronous telehealth platform that lets your dermatologists treat routine cases from patient photos, so your appointments go to the patients who need to be seen in person.

    How it Works

    A second way to see patients

    Today you have one way to see a patient, which is in person. Dappledoc adds an online visit for your routine cases.

    AI Intake & Triage

    Patients submit photos, symptoms and history on your branded intake, and AI routes each case.

    OnlineRashes, acne, follow-ups
    In personBiopsies, procedures

    Two-Minute Review

    Dappledoc puts the answers and photos at the top of the screen and flags anything urgent. The dermatologist reads the case and diagnoses.

    Full Clinical Control: The AI handles intake, summarizing and urgency flagging. It does not diagnose, and it does not prescribe.

    The Complete Visit Flow

    A patient with a rash, acne or a follow-up doesn't need an appointment to get an answer from your dermatologist. This is what happens when they start an online visit with your practice instead.

    The patient sends photos

    It takes under 3 minutes on their phone.

    AI triage routes the case

    Routine cases go online. The rest go in person.

    Routine

    Your dermatologist treats it online

    Diagnosing and prescribing takes about 2 minutes. The patient gets a summary and Rx, and Apotheco fills and ships it nationwide.

    Needs an exam

    Your front desk schedules it

    Each case arrives with an urgency rating, and the patient is not charged.

    Routine cases don't take an appointment slot, and the cases that need an exam get scheduled by urgency.

    The Problem

    The only way to see more patients has been to hire

    A practice can only see so many patients a day, and until now the only way to see more has been to hire more staff. We call that the throughput trap.

    “My schedule is full for months, and many of those appointments take me 30 seconds. I look at a rash and know what it is, but the patient still drove in and sat in the waiting room. Someone who needs a biopsy waits three months for that same slot.”

    How we calculate this
    • Capacity. Eight async reviews in the time one 15-minute in-person visit takes, within the same clinic hours, over 4 weeks a month. Freed slots are assumed to get filled.
    • In-person rates. Billed to insurance, at 2026 Medicare national non-facility allowed amounts: $95 for the low-acuity visit that moves async (99213), and $136 for the in-person visit that fills the freed slot (99214).
    • The async side is not insurance. Patients pay your practice for platform access, and your practice sets the price. The slider starts at $75, the average across standard and priority review.
    • Net, not gross. A case that moves async stops billing insurance and starts earning the platform fee instead. The difference between the two is subtracted from what the freed time earns.
    • Before collection. The two Medicare figures include the patient copay and are what the practice is entitled to on an in-person visit, not what it banks.
    • Conservative. The in-person figure counts the office visit only, so procedures billed on top of a visit are excluded. Actual results vary by practice.

    FAQ

    Questions from practices

    What is Dappledoc?

    Dappledoc is an asynchronous telehealth platform that addresses long wait times in dermatology and gets clinicians paid for their async work. Patients send photos of a skin concern from their phone, AI triage sorts the cases, and the practice's own dermatologists treat the routine ones online. It was designed and co-founded by Dr. Benjamin Marks, a Yale-trained, board-certified dermatologist, and Jon Friedman, the chief design officer at Microsoft.

    Does the AI diagnose patients?

    No. Dappledoc's AI sorts and summarizes cases and flags anything urgent. A dermatologist at your practice makes every diagnosis and writes every prescription.

    How is Dappledoc different from other online dermatology services?

    Many online dermatology companies sell directly to patients and employ their own doctors, so they compete with local practices for patients. Dappledoc sells to the practice. Patients see the practice's name, are treated by its dermatologists and pay the practice directly.

    What kinds of cases can be treated online?

    Routine cases like rashes, acne and follow-ups can be treated online. Biopsies, procedures and anything the AI or the dermatologist flags as needing an exam go to an in-person visit.

    How do practices get paid?

    In-person visits are billed to insurance, exactly as they are today. For online cases, patients pay your practice a platform access fee, at a price your practice sets.

    What happens when a case needs an in-person visit?

    The patient is not charged. The case goes to your front desk with an urgency rating, the reason it needs an exam and the patient's contact details, so your office knows who to call first.

    Is Dappledoc HIPAA compliant?

    Dappledoc is built to HIPAA requirements, and we sign a business associate agreement with every practice. Patient data is encrypted, each practice's data is kept separate from every other practice's, and audit logs are kept from day one.

    Do patients need to download an app?

    No. Dappledoc runs in the browser on a phone or computer. Patients sign in with a one-time code sent by text or email, or with Google or Apple.

    What does setup involve?

    You add your providers, set your price for online cases, add your logo and colors, and share your link with patients. There is nothing to install.

    Who is using Dappledoc now?

    Dappledoc is in pilot with several dermatology practices nationwide and is adding more. Practices can request a demo.
