Su hijo tiene una consulta/cita con el médico mañana a la una y media.
Some offices use the word 'una hora' also for your appointment hour.
The following link is for a dialogue that I had for a class awhile back. It's for a dentist appointment but many of the words are the same and may be of help to you.
