What is telehealth?

Telehealth covers care delivered when the patient and clinician are not in the same place. Common forms include live audio-video visits, audio-only visits, store-and-forward exchange of images or records for later review, and remote patient monitoring.

Telemedicine usually refers to remote clinical services, while telehealth is the broader term that also includes nonclinical uses such as provider training and patient education. Federal programs and state laws define the terms differently, so the legal meaning depends on the program or statute.

How Medicare telehealth coverage works

Under the Medicare statute, telehealth was historically limited to patients in certain rural areas who were at an approved originating site, such as a clinic or hospital, rather than at home. Services must appear on the Medicare Telehealth Services List and be furnished by eligible practitioners.

During the COVID-19 public health emergency, waivers and legislation lifted the geographic and site limits and expanded eligible practitioners and audio-only care. Congress has extended many of those flexibilities several times on a temporary basis, so the rules in force depend on current law. Some changes are permanent, including home-based telehealth for substance use disorder and mental health services, subject to conditions.

Why telehealth matters

Telehealth policy and billing data affect several kinds of analysis:

• Provider targeting: claims with telehealth place of service codes and modifiers show which clinicians and specialties deliver virtual care.
• Network adequacy: Medicare Advantage network adequacy rules give plans limited credit for telehealth providers in certain specialties.
• Pharma and digital health: virtual prescribing, including controlled substances under DEA rules, affects how patients start and stay on therapy.
• Policy tracking: temporary Medicare flexibilities and DEA telemedicine rules have been extended repeatedly, so forecasts should model the risk that they lapse.
