Telehealth can treat a surprisingly broad range of conditions, from everyday infections and skin rashes to chronic diseases like diabetes and heart disease, plus most mental health concerns. The scope has expanded significantly since 2020, and providers can now even prescribe controlled substances via video visits through at least December 2026. Here’s a practical breakdown of what works well over a screen and where the limits are.
Common Acute Illnesses
The bread and butter of telehealth is the kind of thing you’d normally visit urgent care for: colds, sinus infections, sore throats, upset stomachs, headaches, and urinary tract infections. For a UTI, for example, your provider can assess your symptoms over video, order a urine test at a nearby lab if needed, and send a prescription to your pharmacy without an office visit.
Pink eye, swimmer’s ear, and minor skin infections like cellulitis (when there’s no fever) are also well suited to video visits. So are seasonal allergies, mild diarrhea, and reflux flare-ups. The common thread: these are conditions where a visual check and a conversation about your symptoms give the provider enough information to make a diagnosis and start treatment.
Skin Conditions
Dermatology is one of the most natural fits for telehealth because so much of it relies on visual assessment. Rashes, eczema, acne, contact dermatitis, ringworm, minor burns, bug bites, and birthmarks can all be evaluated through a video visit or even by uploading photos for a dermatologist to review later.
That said, accuracy matters. Research published in Frontiers in Medicine found that when teledermatologists evaluated skin growths, their diagnoses matched those of in-person dermatologists about 81% of the time when both complete and partial agreement were counted. For identifying whether a lesion was cancerous or benign, agreement with biopsy results reached about 70%. These numbers are solid for initial screening and triage, but they also explain why providers will still refer you for an in-person visit and biopsy when something looks suspicious.
Mental Health and Behavioral Health
Mental health care may be where telehealth has had its biggest impact. You can access individual therapy, group therapy, text-based therapy, medication prescribing, and ongoing medication monitoring all through virtual visits. Screening for depression and anxiety, ongoing symptom tracking, and addiction counseling are all standard telehealth offerings now.
For substance use disorders, providers can prescribe medications to support recovery via telehealth, including certain controlled substances. The DEA extended its pandemic-era telemedicine flexibilities through December 31, 2026, meaning providers with a DEA registration can prescribe schedule II through V controlled substances without an in-person evaluation, as long as specific conditions are met. This has been particularly important for people in rural areas or those who face barriers getting to an office visit for ADHD medication, anxiety treatment, or addiction support.
Chronic Disease Management
Telehealth isn’t just for one-off sick visits. The CDC’s Community Preventive Services Task Force specifically recommends telehealth interventions for managing high blood pressure, cardiovascular disease, diabetes, asthma, HIV infection, end-stage kidney disease, and obesity. These recommendations are backed by systematic reviews, not just individual studies.
Remote patient monitoring is a key piece of this. You might use a blood pressure cuff at home that sends readings to your provider automatically, or log blood sugar levels through an app your care team reviews between visits. Text message reminders have been shown to improve medication adherence for patients with heart disease, diabetes, HIV, and asthma. Dietary coaching delivered through video, remote monitoring, and mobile health tools has shown benefits for patients managing heart disease, diabetes, kidney disease, and obesity.
The practical upside here is fewer trips to the office for stable chronic conditions. Instead of driving in every month, you might alternate between in-person and virtual check-ins, with your provider watching your data in between.
Pediatric Care
Children’s Hospital of Philadelphia maintains a detailed list of conditions appropriate for pediatric video visits, and it’s longer than most parents expect. Beyond the obvious sick visits for colds and pink eye, it includes behavioral health concerns like ADHD follow-ups, depression, anxiety, sleep problems, school issues, and toilet training. Breastfeeding support, fussy baby concerns, picky eating questions, and feeding disorder follow-ups all work over video.
Skin issues are another big category for kids: diaper rash, eczema, ringworm, acne, minor cuts and burns, and general rashes (as long as there’s no fever and the child is otherwise well). Asthma follow-ups, concussion monitoring (though not return-to-play clearance), constipation, abdominal pain, and even post-hospital discharge check-ins round out the list. For ADHD visits, having a home weight measurement ready before the appointment is helpful since stimulant medications can affect growth.
Physical Therapy and Rehabilitation
Physical therapy over video, sometimes called tele-PT, works well for a range of conditions. Common practice areas include sports injuries, lower limb injuries, lower back pain, functional movement screens, and post-discharge safety evaluations. Pediatric and school-based therapy also translates well to telehealth.
The format typically involves your therapist watching you perform exercises in real time, correcting your form, and progressing your program. It’s also used for home safety evaluations to prevent hospital readmissions, particularly for older adults after a fall or surgery. Researchers at Emory University have developed a web-based rehabilitation program for stroke recovery that focuses on both upper-body exercises and walking training, with family members actively involved in the sessions.
What Providers Can Assess Over Video
One reason telehealth covers so much ground is that providers have developed structured techniques for virtual physical exams. Clinicians can conduct ear, nose, and throat exams, skin assessments, abdominal exams, heart and lung evaluations, neurological checks, and musculoskeletal assessments over video. They look for visual cues like skin discoloration or an unsteady gait, and they’ll often ask you to perform specific movements, press on certain areas, or position your camera to get a closer look.
These exams are more limited than hands-on evaluations, which is why providers will escalate to an in-person visit when they can’t get the information they need. But for most straightforward complaints, a skilled clinician can gather enough data through video to make sound clinical decisions.
What Telehealth Can’t Handle
The conditions that don’t work well over video share a few traits: they require hands-on examination, lab work or imaging that can’t wait, or immediate physical intervention. Chest pain, difficulty breathing, severe abdominal pain, signs of stroke, broken bones, deep lacerations, and any situation that feels like an emergency belongs in an ER, not on a screen.
Conditions that need palpation (feeling a lump, checking for tenderness in a specific spot) or auscultation with specialized equipment (listening to heart murmurs, for instance) are also better suited to in-person care, at least for the initial evaluation. New, complex, or rapidly worsening symptoms generally warrant being seen in person. The same goes for procedures like wound suturing, joint injections, or any condition where a provider needs to physically intervene.
For everything in between, telehealth has become a reliable first step. Many visits that start virtually stay virtual. Others serve as triage, helping you and your provider decide whether an in-person visit is necessary, and how urgently.
