ap-pun-ta-MEN-to — double 'p' and 't' are both pronounced, giving a clipped quality. DOT-to-re.
Say this at the reception desk when you arrive at a clinic or GP surgery. It confirms your visit is expected.
'Ho' is the first person singular of 'avere' (to have). 'Un appuntamento' means 'an appointment' — the same word is used for any scheduled meeting, not just medical ones. 'Con il dottore' means 'with the doctor'; 'dottore' is the standard respectful title for any graduate in Italy, not only medical doctors.
Ho prenotato una visita per oggi.

In Italy, the public GP is called 'medico di base' or 'medico di famiglia'. Every resident registers with one for free care under the SSN (Servizio Sanitario Nazionale). Tourists with an EHIC (European Health Insurance Card) can access urgent public healthcare. Private visits ('visite private') are faster but cost €50–150.
