This form is a contract between a medical practitioner and a patient that allows the practitioner to collect fees from the patient. It is typically signed after a consultation between the patient and the practitioner. It is possible for the practitioner and the patient to agree to waive any fees, or to defer payment of fees until the patient becomes capable of paying. Consent forms are used in family medicine and general practice, as well as in specialties such as orthopedics and ophthalmology.
