Things to Know
Generally, we accept walk-in patients from 8:00 to 10:30 a.m. and 1:00 to 3:30 p.m., Monday to Friday. Walk-in patients are seen as soon as possible, however, patients with appointments or emergency situations will take precedence.
If you are a new patient, we ask that you arrive at least 30 minutes before your appointment time (unless your doctor has asked you to come in earlier). This will allow you time to complete necessary documents such as the patient registration form, patient financial agreement, release of information form, privacy disclosure, and healthcare questionnaires.
Please bring the following items with you on your first visit to American Medical Center:
– Valid photo identification such as a driver’s license, passport, or U.S. government issued identification.
– Insurance card
– Immunization record
– List of prescribed medication(s) and dosage (alternatively you can bring all prescribed medication on your visit)
– Recent laboratory results if available
Please bring Form 101a (issued by your employer).
If you are also a new patient, please click on the “New Patient” button for additional requirements.
While we make every effort to ensure that we see you on time for your scheduled appointment, events occur that may cause your medical provider to run late. When this happens, we will inform you and give you the option to:
– Continue to wait for your provider, or
– See another available medical provider, or
– Re-schedule your appointment for the next earliest available opening.
Please call our clinic at least 24 hours in advance if you are not able to make your appointment and to avoid the missed appointment fee.
Same-day appointments may be available; please call our clinic at 8:00 a.m. Monday to Friday, or at 9:00 a.m. on Saturday to schedule a same-day appointment. We will make every effort to accommodate your request.
For a serious emergency, call 911 right away. If you are not sure and you call our clinic, please let the person who answers the telephone know that it is an emergency.
Patients under the age of 18 must be accompanied by a responsible adult or have written permission for treatment from a parent or guardian.
Annual physical exams are an important part of good health maintenance. If you have health insurance, it is a good practice to understand what benefits are covered by your insurance plan since insurance benefits will vary.
If you are scheduled for diagnostic testing such as lab, ultrasound, sleep study, X-ray or other similar type of testing, please schedule a follow up appointment with your primary care provider to review the results. Follow up appointments may be subject to a co-payment depending on your health insurance plan.
Please note the following guidelines regarding prescription medication:
+If you need to call in for a refill, please plan and call several days in advance. Refills require your doctor’s approval – sometimes this approval is obtained the following business day after you call. The best time to get a prescription refill is at your appointment.
+Some medications have potential side effects that must be monitored. We require follow up appointments for these medications. When your follow up appointment is scheduled, it is important to keep the appointment.
+We do not refill chronic narcotic pain medication.
Referrals are handled by our administrative staff. Depending on the nature of the referral and the urgency of the situation, a referral may require a prior authorization from your health insurance company. If a prior authorization is required, you will be contacted by American Medical Center when the prior authorization is received from your health insurance company.
