Learn About Telehealth and When It May Help

What Is Telehealth and How Does It Work?

Telehealth is the delivery of healthcare services using technology—primarily video calls, phone conversations, and secure messaging. Instead of traveling to a doctor's office or hospital, you connect with a healthcare provider from your home, workplace, or another location with internet access. The provider uses the same clinical skills and training they would use in person, but the interaction happens remotely.

Telehealth includes several types of services. Video visits are the most common, where you and your provider can see and hear each other in real time through a secure video platform. Phone visits occur when you speak with a provider by telephone instead of video. Remote patient monitoring involves devices that track your health data—like blood pressure or glucose levels—and send that information to your provider. Store-and-forward technology lets you send photos, videos, or health information to a provider who reviews it later and responds.

According to the U.S. Department of Health and Human Services, telehealth visits increased dramatically from fewer than 1% of all healthcare visits in 2019 to over 38% by 2021, showing how widely this service has become available. The technology behind telehealth typically requires a device with internet access (smartphone, tablet, or computer), a camera and microphone, and a secure connection to the healthcare provider's platform.

Telehealth operates within the same regulatory and privacy standards as in-person care. Providers must be licensed in the state where you live, and all information is protected under privacy laws like HIPAA. The provider's office handles scheduling, billing, and medical records the same way they would for office visits. Your medical information stays confidential, and the platforms used for video visits are encrypted to protect your data.

Practical Takeaway: Telehealth is a legitimate healthcare delivery method using secure technology. Understanding the basic types of telehealth services—video visits, phone calls, and remote monitoring—helps you know what to expect when you use these services.

Common Types of Conditions Treated Through Telehealth

Many health conditions can be addressed through telehealth visits. Routine care, follow-up appointments, and management of ongoing health issues are well-suited to remote visits. For example, if you have diabetes and your provider needs to review your blood sugar logs and adjust your medication, a telehealth visit works well for this conversation. Similarly, if you take medication for high blood pressure and need a refill with a quick check-in, telehealth can handle that efficiently.

Mental health services have become one of the most common uses of telehealth. Therapy sessions, counseling, and psychiatric consultations work effectively over video. The American Psychological Association reports that telehealth therapy has similar outcomes to in-person therapy for many conditions, including depression, anxiety, and post-traumatic stress disorder. A person struggling with anxiety can schedule a video therapy session without the transportation barriers that might prevent them from attending in-person appointments.

Urgent care needs that don't require physical examination also benefit from telehealth. If you have a cold, sore throat, or urinary tract infection, a provider can often diagnose and recommend treatment through a video visit. Dermatology—the treatment of skin conditions—is another specialty well-suited to telehealth, since providers can often assess skin problems through video or photos. A patient with a suspicious rash can send photos to their dermatologist, who can provide guidance on whether an in-person visit is necessary.

Chronic disease management represents a significant portion of telehealth use. People with conditions like heart disease, asthma, arthritis, or chronic pain can use telehealth for regular monitoring and medication adjustments. For example, a patient with congestive heart failure might use a remote monitoring device to track weight and fluid retention, with results automatically sent to their cardiologist. This approach allows providers to catch problems early and adjust treatment plans without waiting for the next scheduled office visit.

Telehealth works less well for conditions requiring hands-on physical examination or procedures. A suspected broken bone typically needs an X-ray, which requires an in-person visit. Similarly, a comprehensive physical examination by palpation—where a provider feels organs and tissues—cannot be done remotely. Many telehealth providers will refer you to an in-person visit when your situation requires it.

Practical Takeaway: Telehealth works well for managing chronic conditions, follow-up care, mental health services, and some acute illnesses. Knowing which types of conditions are suited to telehealth helps you decide whether this option makes sense for your particular health situation.

Advantages and Limitations of Telehealth

Telehealth offers several concrete advantages for patients and providers. Convenience is a major benefit—you avoid travel time and can often schedule appointments during flexible hours, including evenings and weekends. For people with mobility limitations, chronic pain, or transportation barriers, this difference is significant. A person with severe arthritis who struggles to drive can receive care from home. Parents with young children avoid the challenge of arranging childcare for a doctor's appointment. People living in rural areas with limited healthcare providers can connect with specialists in distant cities.

Cost considerations make telehealth attractive for many people. Telehealth visits often cost less than in-person visits because providers have lower overhead expenses. You save money on transportation, parking, and time away from work. Some studies show that telehealth reduces overall healthcare costs by preventing unnecessary emergency room visits when minor issues can be handled promptly by a primary care provider. However, costs vary widely depending on your insurance coverage and which provider you use, so you should always verify costs before scheduling.

Speed of access is another advantage. If you need care for a minor health concern, telehealth often means you can see a provider the same day or within hours, rather than waiting weeks for an in-person appointment. This rapid access may prevent a minor condition from worsening. During times of high disease spread—like during the flu season or pandemic—telehealth reduces exposure risk for both patients and healthcare workers.

However, telehealth has real limitations. Technology barriers affect people without reliable internet, smartphones, or computers. According to the U.S. Census Bureau, approximately 21 million Americans lack broadband internet access, meaning telehealth is not an option for them. Some people struggle with technology and may find video visits stressful or difficult to navigate. Age, disability, or language barriers can make telehealth platforms challenging to use.

Clinical limitations are also important. Providers cannot perform physical examinations, listen to your heart and lungs with a stethoscope, or feel your abdomen. This means certain diagnoses require in-person visits. Some patients, particularly those with complex medical histories or multiple health conditions, may need the comprehensive evaluation that only an in-person visit provides. Building a relationship with a new provider through telehealth alone can be harder than meeting in person, and some patients prefer in-person interactions.

Practical Takeaway: Telehealth offers real benefits in convenience, cost, and speed, but it has genuine limitations in clinical assessment and technology access. Understanding both sides helps you make informed decisions about when telehealth suits your needs.

How to Prepare for a Telehealth Visit

Preparing for a telehealth visit involves practical steps that ensure your appointment goes smoothly. First, test your technology before the scheduled appointment time. Make sure your device—smartphone, tablet, or computer—has a working camera and microphone. Download any required app or software at least 24 hours in advance, allowing time to troubleshoot if problems occur. Check your internet connection by doing a simple speed test; most telehealth platforms work well with standard household internet speeds.

Choose a quiet, private location for your visit. This might be a bedroom, office, or any room where you won't be interrupted. Close doors and minimize background noise. Let family members or housemates know you're having a medical appointment so they can respect your privacy. Your provider needs to hear you clearly, and you need to hear them. Ensure your location has adequate lighting—natural light or a lamp behind your camera works well—so your provider can see you clearly if needed.

Gather your medical information before the appointment. This includes a list of current medications (including over-the-counter drugs and supplements), your medical history, any recent test results, and a written list of symptoms or concerns you want to discuss. Having this information organized prevents you from forgetting important details during the visit. If you're following up on a previous issue, have your notes about how you've been feeling since the last appointment.
