Telehealth: Frequently Asked Questions

Telehealth sits at the intersection of medicine, technology, law, and insurance — which means almost everyone who encounters it has questions, and almost no one gets a complete answer in one place. These eight questions address the mechanics, the rules, the misconceptions, and the practical realities of receiving or delivering care at a distance, across the full range of services telehealth encompasses.

How does classification work in practice?

Telehealth is not a single category — it breaks into distinct modalities that carry different regulatory and reimbursement implications. The three primary types are synchronous video visits (live, two-way audio-video between patient and provider), store-and-forward telehealth (asynchronous transmission of clinical data like images or lab results to a provider who reviews them later), and remote patient monitoring (continuous or periodic collection of biometric data — blood pressure, glucose, weight — transmitted from home devices to a clinical team).

Medicare billing, for example, treats these three types under separate billing codes. The Centers for Medicare & Medicaid Services (CMS) publishes the applicable HCPCS and CPT code sets each year in the Physician Fee Schedule. A synchronous visit billed under 99213 carries different coverage criteria than a remote monitoring service billed under 99454. Getting the classification wrong at the point of billing is one of the most common sources of claim denial and compliance exposure for provider organizations.

What is typically involved in the process?

A standard telehealth encounter — the synchronous video visit most people picture — involves five operational steps:

1. Scheduling and intake: The patient books through a portal or app; the platform confirms insurance eligibility before the appointment.
2. Informed consent: Most states require documented telehealth-specific consent separate from general treatment consent. See telehealth informed consent for state-by-state requirements.
3. Identity verification: Providers confirm the patient's location and identity, partly because some prescribing rules require knowing the patient's physical state at the time of the visit.
4. Clinical encounter: The visit itself, conducted over a HIPAA-compliant platform. The provider documents the encounter in the EHR using the same standards as an in-person note.
5. Billing and follow-up: The encounter is coded, submitted to the payer, and any follow-up care — referrals, prescriptions, labs — is coordinated.

That last step is where complexity concentrates. Telehealth billing and coding requires modifiers (notably the -95 modifier for synchronous telehealth) that in-person billing does not.

What are the most common misconceptions?

The most durable myth is that telehealth is essentially a lesser version of in-person care — a convenience trade-off. The telehealth research and evidence base tells a more nuanced story: for specific conditions including hypertension management, depression screening, and dermatological triage, telehealth outcomes are statistically comparable to in-person care. The telehealth vs in-person care comparison depends heavily on clinical context, not on the delivery channel itself.

A second common misconception is that a provider licensed in one state can freely see patients in any other state via telehealth. Licensure follows the patient's physical location, not the provider's. A physician in New York seeing a patient who is physically in Texas must hold a Texas medical license, with narrow exceptions for interstate compacts like the Interstate Medical Licensure Compact, which covers 40 states and territories as of the compact's most recent enrollment data (IMLC).

Where can authoritative references be found?

The primary federal sources are CMS (cms.gov) for Medicare and Medicaid telehealth coverage, the Office for Civil Rights at HHS (hhs.gov/ocr) for HIPAA telehealth guidance, and the DEA for prescribing rules governing controlled substances via telehealth. The National Telehealth Authority home page aggregates policy developments and links primary sources across these agencies.

State medical boards publish telehealth-specific practice standards; the Federation of State Medical Boards (FSMB) maintains a consolidated resource. For peer-reviewed clinical evidence, the Agency for Healthcare Research and Quality (AHRQ) publishes systematic reviews on telehealth effectiveness across specialties.

How do requirements vary by jurisdiction or context?

Dramatically. As of the Interstate Medical Licensure Compact's published enrollment, 40 jurisdictions participate — but the remaining states require full individual licensure through their own boards, with processing times ranging from 30 to 180 days depending on the state. Telehealth state laws and licensure covers this variation in detail.

Prescribing rules add another layer. The Ryan Haight Online Pharmacy Consumer Protection Act of 2008 historically required an in-person evaluation before prescribing Schedule II-V controlled substances via telehealth. DEA telemedicine rules issued in 2023 introduced a registration framework that modifies — but does not eliminate — that requirement. Telehealth prescribing rules tracks the active regulatory state.

Context matters beyond geography. Hospital-based providers face credentialing and privileging requirements under CMS Conditions of Participation that independent practitioners do not. Rural health clinics operate under different originating site rules than urban federally qualified health centers.

What triggers a formal review or action?

Three categories of events reliably attract regulatory or payer scrutiny. First, billing anomalies — a provider whose telehealth claim volume is statistically disproportionate to their specialty peer group. CMS data analytics flag outliers for medical review. Second, prescribing patterns — particularly for Schedule II-IV controlled substances where DEA registration requirements apply. Third, patient complaints to state medical boards alleging that a telehealth provider prescribed without adequate evaluation.

Telehealth malpractice and liability examines how standard of care is evaluated in the telehealth context — a question courts have addressed with increasing specificity as telehealth utilization scaled through and after 2020.

How do qualified professionals approach this?

Experienced telehealth providers treat the modality as a distinct clinical environment, not a video-enabled photocopy of an office visit. That means adapting history-taking techniques to compensate for the absence of physical examination, being explicit about when a patient needs in-person evaluation, and building workflows that account for technical failure.

On the administrative side, telehealth clinical workflows and credentialing due diligence are non-negotiable starting points for any provider organization launching telehealth services. Licensing across multiple states requires legal counsel familiar with each state's medical practice act and telemedicine-specific statutes. Telehealth credentialing and privileging walks through the hospital-side requirements that govern provider verification.

What should someone know before engaging?

Whether engaging as a patient or a provider, the foundational question is coverage and cost. Medicare telehealth coverage and Medicaid telehealth coverage each carry specific eligibility rules — not every service is covered under every plan, and coverage rules differ for Medicare Advantage versus traditional Medicare. Private insurance telehealth coverage varies by state insurance law; 43 states have enacted some form of telehealth parity law, though the scope of parity obligations differs considerably across those statutes.

For patients in underserved areas, the practical constraints of telehealth broadband and connectivity and the digital divide are as relevant as any coverage rule. A telehealth benefit is only meaningful if the patient has a device and a connection adequate for a synchronous video visit — a condition that 21 million Americans in rural areas cannot reliably meet, according to FCC deployment data (FCC Broadband Deployment Report).
