Synchronous Telehealth Explained: What It Means for Your Parent's Care

When you start researching telehealth options for an elderly parent, you'll run into terminology that sounds more like a technology textbook than a healthcare conversation. "Synchronous telehealth," "asynchronous care," "store-and-forward" — these terms come from healthcare policy and medical billing, but they have real implications for how your parent receives care and what to expect from different types of virtual visits.

This post decodes the key terms so you can make sense of what your parent is being offered.

What "Synchronous" Means in Telehealth

Synchronous means real-time. A synchronous telehealth visit is a live, two-way interaction between a patient and a provider that happens at the same moment — the same way an in-person office visit does, just over a video or phone connection.

When most people think of "telehealth" or a "virtual doctor's appointment," they're thinking of synchronous telehealth. The doctor is on screen, the patient is on screen, and the conversation happens in real time.

The most common form of synchronous telehealth is a live video visit: a scheduled appointment where your parent joins a video call with their doctor or specialist, the provider conducts the visit, and both parties can ask and answer questions as they would in an exam room.

Audio-only synchronous telehealth is also possible — and importantly for seniors, Medicare permanently covers audio-only visits for mental health services, recognizing that not all elderly patients have the device capability or comfort level for video. An audio-only telehealth appointment is still synchronous (it happens in real time) even without video.

What "Asynchronous" Telehealth Means

Asynchronous means not in real time. The patient and provider are not communicating simultaneously; instead, information is sent, reviewed later, and responded to.

Common forms of asynchronous telehealth include:

Store-and-forward: The patient (or caregiver) sends photos, test results, or recorded information to a provider, who reviews it later and responds. Dermatology often uses this model — a patient photographs a skin lesion and uploads it; a dermatologist reviews it asynchronously and sends a written assessment or prescription without a live visit. Some telehealth platforms (including certain MDLive dermatology services) use this approach.

Secure messaging with the care team: Sending a message through a patient portal (like MyChart) to a nurse or provider, who responds within a business day or two. This is common for medication refill requests, non-urgent questions, and lab result questions.

Remote patient monitoring (RPM) review: When a senior wears a device (blood pressure cuff, glucose monitor, cardiac monitor) that transmits data to the care team for review and action, that review is typically asynchronous. The provider reviews the data log and reaches out if a concern emerges, rather than watching it in real time.

Why the Distinction Matters for Your Parent's Care

Understanding synchronous vs. asynchronous helps you know what kind of visit to expect and whether the format is appropriate for what your parent needs.

Synchronous visits are better for:

• Anything requiring a real-time examination (visual assessment, cognitive testing, movement evaluation)
• Conversations that need clarification or follow-up questions on both sides
• Medication changes where the provider needs to observe the patient's reaction
• First-time visits with a new provider who needs to establish rapport and baseline
• Dementia and cognitive assessment — the dynamic nature of the interaction matters
• Urgent issues where a back-and-forth exchange needs to happen quickly

Asynchronous approaches are better for:

• Routine prescription refills with no changes
• Submitting a photo of a skin condition for initial triage
• Non-urgent questions that can wait for a next-business-day response
• Sharing documents, lab results, or records with the care team

Most of your parent's meaningful healthcare interactions — the ones that involve a physician exercising judgment about their condition — should be synchronous. Asynchronous tools are useful for the administrative and logistical side of managing care.

What "Virtual Visit" and "Virtual Appointment" Mean

These terms are used interchangeably across different health systems, and they almost always refer to a synchronous telehealth visit — a live, real-time interaction with a provider via video or phone.

If your parent's doctor's office offers "virtual visits" or "virtual appointments," this means they can schedule a live appointment and conduct it over video instead of coming into the office. The clinical content of the visit is the same; only the location changes.

A few things to know:

Your parent is still the patient of their own doctor. A virtual visit with a parent's regular physician means that doctor has their full history, medications, and prior notes. This is different from on-demand telehealth with a stranger-doctor.

Scheduling works the same way. The patient (or caregiver, with proxy access) schedules a virtual appointment through the same portal they'd use to schedule an in-person appointment, often selecting "Video Visit" or "Telehealth" as the visit type.

A link or call-in number is provided. Before the appointment, the patient portal or an email reminder typically provides a link to click at the appointment time, or a phone number to call. The technical barrier is usually just clicking that link.

The "Virtual Visit" Technology Your Parent Will Use

The term "virtual visit" doesn't specify which technology is used. Different health systems use different platforms:

• Zoom for Healthcare (a HIPAA-compliant version of Zoom)
• Doxy.me (a browser-based platform that doesn't require an app download — simply clicking a link opens the visit)
• Teladoc (when the health system contracts with Teladoc for their telehealth platform)
• Epic MyChart Video Visits (integrated directly into the MyChart patient portal)
• Microsoft Teams (used by some VA and large health system providers)

For elderly patients, browser-based platforms like Doxy.me are often easiest because they don't require any app installation — the parent just clicks a link. For platforms that require app downloads (some MyChart integrations), it's worth setting up and testing the app before the appointment day.

Synchronous Telehealth Under Medicare

Medicare covers synchronous telehealth visits — both video and audio-only — for many service types. The 2025 rules made several telehealth expansions permanent:

• Geographic restrictions eliminated for behavioral health (patients can be anywhere, including home)
• Audio-only permanently covered for mental health services
• The patient's home qualifies as an originating site

For non-behavioral health services, most synchronous telehealth coverage is also in place through extensions, though the policy landscape continues to evolve. If your parent is using Medicare and has a question about whether a specific type of visit is covered, the provider's billing department can confirm.

Putting It Together for a Caregiver

When you're setting up telehealth for an elderly parent, here's the practical translation:

• A "synchronous telehealth" or "virtual visit" appointment = a live call with a real provider, video or phone, scheduled in advance or on demand
• "Asynchronous" tools = patient portal messages, photo submissions, remote monitoring data — useful supplements but not replacements for live clinical conversations
• "Store-and-forward" = the provider will look at something you send later; expect a response in hours or days, not minutes

For the bread-and-butter of your parent's care — chronic disease management, medication reviews, specialist consultations — synchronous visits are what you want to prioritize. The asynchronous tools save time and trips to the office for the simpler tasks.

Our Telehealth Parent Guide covers how to set up your parent for synchronous video visits specifically — including device setup, accessibility configuration, lighting and audio tips, and how to join the visit alongside your parent as a caregiver participant. If you're new to managing telehealth for a parent, it's the practical starting point that the jargon-heavy healthcare websites don't provide.
