What the law turns on
There's no single answer that covers every appointment in the United States. Federal law sets the floor: under 18 U.S.C. 2511(2)(d), it isn't unlawful for a private person, one not acting under color of law, who is a party to a conversation to record it, or for someone to record with one party's prior consent, unless the recording is made for the purpose of committing a criminal or tortious act under federal or state law. State law can require more than that, and the office can have its own policy, which is why the rule here is to ask everyone in the room.
Because of that, a state list copied off the internet doesn't settle it. Which law applies can depend on where each participant is sitting, which matters for a phone or telehealth visit, laws change, and a health care organization can address recording through its own policy whatever the law allows. If you need certainty, check the current law for the relevant state or ask a lawyer.
Asking first is the practical rule, and it isn't only a legal hedge. It protects the working relationship, it lets the clinician avoid discussing someone else's information while a recorder is running, and it gives the office a chance to offer an alternative if recording isn't allowed there.
