Asynchronous Teledermatology: Where It Works and Where It Doesn't

Dermatology is the specialty best suited to store-and-forward care, and the one where the rules on asynchronous visits matter most. Where state law lets photos and history establish a patient relationship, why Medicare mostly does not pay for store-and-forward visits, which conditions and drugs need more than a photo, and how to design the visit.

Asynchronous teledermatology works where three things line up: the state lets a store-and-forward visit establish the patient relationship, the condition can be judged from good photos and a structured history, and the payer pays for it or the patient pays cash. It does not work for lesions that need palpation or dermoscopy the patient cannot provide, for drugs with monitoring programs that need more than a photo, or for Medicare patients outside narrow exceptions.

Where can a store-and-forward visit start the relationship?

State by state. Texas is a clear example of a state that allows it with conditions: under Texas Occupations Code § 111.005(a)(3)(B), a valid practitioner-patient relationship can be formed through "asynchronous store and forward technology" as long as the practitioner uses clinical information from "clinically relevant photographic or video images, including diagnostic images" or the patient's relevant clinical records, and meets the standard of care. Section 111.005(b) then requires the practitioner to give the patient guidance on follow-up care and, if the patient consents and has a primary care physician, to send that physician a report within 72 hours.

Florida's statute defines telehealth to include asynchronous technology and lets a telehealth provider perform a patient evaluation by telehealth (Fla. Stat. § 456.47). Other states require a synchronous interaction for the first visit, or restrict prescribing after an asynchronous-only encounter. Check every state you serve; see asynchronous telehealth by state and our state law pages.

Does Medicare pay for asynchronous dermatology?

Mostly no, as a Medicare telehealth service. The telehealth statute (section 1834(m) of the Social Security Act) allows asynchronous store-and-forward only for federal telemedicine demonstration programs in Alaska and Hawaii, and the current flexibilities through December 31, 2027 did not change that. Medicare does pay for some communication-based services that are not Medicare telehealth services, such as remote evaluation of images an established patient sends and online digital evaluation services through a portal, each with its own conditions. Code-level questions go to White Glove Medical Billing. Commercial payers and Medicaid programs set their own rules.

Which conditions fit asynchronous care?

Good fits, with a structured history and good photos:

acne and rosacea follow-up;
uncomplicated eczema and psoriasis management;
common rashes with a clear history;
hair loss evaluation, with a defined photo set;
medication refills for stable chronic conditions.

Poor fits, which should convert to synchronous video or in-person care:

any changing, bleeding or new pigmented lesion that could be melanoma;
rapidly spreading rash with fever or systemic symptoms;
wounds, infections that may need drainage, or anything near the eyes;
patients whose photos are not diagnostic after one retake.

Which drugs need more than a photo?

Isotretinoin is prescribed under FDA's iPLEDGE risk evaluation and mitigation strategy, which adds prescriber, patient and pharmacy steps every month. Build those steps into the program before offering it.
Systemic immunosuppressants and biologics often call for screening and monitoring labs. Add a lab partner first. See lab partners for telehealth.
Any prescription after an asynchronous-only encounter must satisfy state prescribing rules, including any ban on prescribing from a questionnaire alone. See where questionnaire-only prescribing is prohibited.

How should the asynchronous visit be designed?

A condition-specific history form written by a dermatologist, with stop questions that route to a live visit.
Photo instructions with examples: distance, lighting, scale reference, multiple angles. Reject and request retakes when quality is poor.
Patient location and identity captured at submission, since licensure follows the patient. See patient location verification.
A turnaround standard, and a path to a live visit if the clinician needs one.
Follow-up guidance given to every patient, and reports to the primary care physician where a state such as Texas requires them.
Photos stored as part of the medical record, with retention under state law.

Does cash-pay change anything?

It removes payer rules, not state law. A cash-pay asynchronous visit still has to satisfy the patient's state on relationship, consent and prescribing, and the price and what it includes (one review, a follow-up message, a live visit if needed) should be clear before the patient pays. If the practice never bills insurance electronically, confirm its HIPAA status with counsel, because that changes which privacy rules govern the photos.

How should photos be protected?

Skin photos can be identifying and sensitive. Keep them inside the HIPAA-covered system, never in email or consumer messaging apps, and keep third-party tracking off the upload and intake pages. See tracking pixels on telehealth sites.

Our State Expansion Pack ($595 per state) answers the asynchronous questions for each state you plan to serve; the 50-State Telehealth Matrix ($2,950) covers all of them for one service line. See pricing.

Common questions

Can an asynchronous visit establish a doctor-patient relationship?

In some states. Texas Occupations Code § 111.005 allows it through store-and-forward technology using clinically relevant images or records, with follow-up guidance and a report to the primary care physician within 72 hours if the patient consents. Other states require a synchronous first visit.

Does Medicare pay for store-and-forward teledermatology?

Not as a Medicare telehealth service, except in federal telemedicine demonstration programs in Alaska and Hawaii. Medicare does pay for some separate communication-based services, such as remote evaluation of images from established patients, under their own conditions.

Which skin conditions should not be handled asynchronously?

Changing, bleeding or new pigmented lesions that could be melanoma, rapidly spreading rashes with systemic symptoms, wounds and possible abscesses, problems near the eyes, and any case where photos are not diagnostic after a retake should move to video or in-person care.
