Two terms show up constantly in telehealth policy discussions: originating site and distant site. They sound like minor technical jargon, but the distinction underneath them has shaped a fair amount of telehealth regulation, and it is worth understanding even as some of the older restrictions tied to these terms have loosened.
Defining the two terms
The originating site refers to the location of the patient at the time a telehealth service is delivered — historically, this might be a clinic, hospital, or other approved facility, though home has increasingly been recognized as an eligible originating site in many contexts. The distant site refers to the location of the physician or other provider delivering the service remotely. The pairing of these two locations is what a telehealth encounter fundamentally consists of.
Why the distinction mattered historically
Under traditional Medicare telehealth policy, originating site restrictions were a significant limiting factor: eligible originating sites were generally limited to specific facility types, often in designated rural areas, which meant a patient at home in an urban area might not qualify for reimbursed telehealth services under those older rules. Distant site rules, separately, governed which types of providers could bill for services delivered remotely.
Originating site is about where the patient sits; distant site is about where the clinician practices — both locations matter to how a telehealth visit is regulated.
How this plays out today
Many of the geographic and facility-type restrictions tied to originating site have been relaxed through temporary flexibilities in recent years, expanding the range of settings, including a patient's home, that can qualify. Even so, the underlying framework of originating and distant site persists in program rules and billing guidance, and some restrictions may re-emerge or shift as flexibilities are extended or allowed to lapse.
Why this still matters for licensure
The distant site concept connects directly to licensure questions, since a physician's distant site location does not typically exempt them from needing to be licensed in the state where the patient — the originating site — is physically located at the time of the visit. Physicians practicing across state lines via telehealth generally still need to track licensure requirements in the patient's state, regardless of where the physician is sitting.
Originating and distant site rules differ by payer and program, and continue to evolve. Requirements vary by state and change over time — always confirm current requirements directly with the relevant state board or agency before making a compliance decision.
