Originating site is Medicare's term for the physical location of the patient during a telehealth visit — literally, where the patient's body is when the encounter happens. It pairs with the "distant site," where the clinician is. This sounds like an administrative footnote, but it is one of the most consequential reimbursement rules in telehealth, because it can decide whether a visit is payable at all.
Historically, Medicare restricted the originating site to clinical facilities (such as a clinic or hospital) located in designated rural areas, which effectively excluded the patient's own home. Pandemic-era flexibilities removed much of that restriction: under current rules the patient's home qualifies as an originating site for most services through December 31, 2027, and permanently for behavioral and mental health services. Because these flexibilities have expiration dates and have been extended more than once, the safe engineering stance is to treat the rule as configurable, not hard-coded.
For a product team, the originating-site rule is a requirement in disguise. To bill correctly you must capture and store where the patient actually was during the visit, validate it against the current rule set, and surface the right place-of-service information to billing. A common pitfall is hard-coding today's pandemic flexibilities as if they were permanent; when a deadline lapses or shifts, claims silently start to deny. Build the location capture and the eligibility rules as data you can update, and keep an audit trail of the patient's stated location for each encounter.
