Patient Policies

Please review these important practice guidelines.

Cancellation Policy: Please give us at least 3 business days’ notice if you are unable to make a scheduled appointment.  When you do not show up, it creates an unused appointment slot that could have been used for another patient; therefore, you will be charged $50 for a no-show.  The no-show charge must be paid by the patient and cannot be billed to insurance.

Children: It is best not to bring children to your appointment in order to avoid distraction and for their safety.  All children under the age of 10 must be accompanied by an adult.

Emergencies: If you have an emergency after hours or on weekends, please call our office and the answering service will connect you with the physician on call. In case of life threatening emergencies, please call 911.

Medicine Refills: Please call for medicine refills during office hours, at least 5 days before you run out. Medicine refills are not called in after hours.  Patients may need an office visit prior to processing a refill. You may also obtain refills from your primary care physician.

Pain Medicines: Lafayette Gastroenterology does not prescribe chronic pain medications. You will need to contact your primary care physician for chronic pain medications.

Payment Policy: Payment is collected at the time of service. We will be glad to bill your insurance. However, if you have a co-payment, unmet deductible, or are responsible for a percentage of the charges, please bring a form of payment with you to your appointment. We accept cash, personal checks, MasterCard and Visa

New Patient Forms

Please print off and complete the New Patient Packet and Health Records Release Authorization  prior to your appointment.  Bring the forms to your appointment.
