The Telephone Consumer Protection Act is the federal statute, enforced by the FCC, that governs automated calls, prerecorded messages, and texts to consumers. It sets rules on prior consent, permissible calling hours, identification, and, critically, the obligation to honor a recipient's request to stop.

Healthcare has particular treatment under the TCPA: certain treatment-related and appointment messages are given allowances distinct from marketing, but the protections still apply, and consent and opt-out obligations remain. Marketing-style outreach faces a higher consent bar than operational, care-related messages.

The practical requirement is disciplined opt-out handling and clean consent state. Rivvi honors TCPA opt-out on every outreach path, voice and text, and stops contacting a patient the moment they opt out, so practices can run outbound programs at volume without crossing the line.
