Office Policies

Privacy Notice

We adhere to strict privacy practices Due to these standards, it is important that you provide us with the preferred communication method where we can leave confidential information. We need permission from you before we can leave a detailed message on your voicemail or send results or answer questions via email. It is also important that you provide us with the names of those who may call on your behalf. We are unable to discuss results with your spouse or children, for example, unless you give us permission to do so.


We can be reached at 650-988-7488 between 9 am and 4:30 pm, Monday through Friday. Please describe the nature of your problem to the person making your appointment. New patients should fill out registration and medical history forms ahead of time and bring a copy of their insurance card and driver’s license or identification card for the initial visit. Whenever possible, medical records should be faxed to our office (650)988-7486. Please bring a list of current medications with you along with any recent labs or radiology results. When you arrive for the appointment, please notify the receptionist if you have had any tests done recently so we can ensure the results will be available for review during your appointment. If you must cancel an appointment, please provide us with as much advance notice as possible.

Physician Assistants

In order to accommodate our patients in a timely fashion, Dr Marcus utilizes Physician Assistants to evaluate patients during their initial consultation. After each consultation, Dr Marcus reviews the notes from the visit and is actively involved in the care of each patient. Because Dr Marcus primarily performs procedures at the surgery center here in our office, he is also available to be brought in to the appointment should the situation arise. Please click here for a more detailed description of the role of a Physicians Assistant.


Office Visits: Our office policy is to require at least 24 hours notice of cancellation of a booked appointment. Failure to provide adequate notice may result in a missed appointment fee from your physican. (Missed new patient appointment: $75. All other visits: $50)

We do make reminder calls for appointments 3 business days in advance. However, since this is done as a courtesy to you, if you do not receive the message or we have incorrect information on file, the cancellation policy will still be in effect.

Procedures: We would like you to be aware that the scheduling process for an endoscopy/colonoscopy procedure involves coordinating the schedules of your physician, the procedure room, and the necessary staff. Due to the high demand for endoscopy procedures, the procedure room is typically booked one month in advance.

In the absence of adequate notice, cancellations result in a waste of key resources as it is often not possible to schedule another case in the same time slot without adequate notice. For this reason you will be asked to sign a statement acknowledging your understanding and acceptance of our cancellation policy. This policy stipulates (apart from exceptional circumstances) that if you cancel/reschedule your procedure with less than a five business day notice or fail to keep your appointment, you will be charged a $200.00 fee. If you cancel your procedure with more than five business day notice no charge will be made.

Insurance Plans:

Apart from HMOs, we have enrolled in numerous managed care insurance plans. However, it is the patient’s responsibility to contact his/her insurance company to determine if our physicians are preferred providers.
Please be advised that insurance companies never guarantee payment or coverage for a procedure. Once the claim has been submitted, it is left to the company’s discretion how much will be paid.
Be sure check with your health insurance plan if you have any questions related to the services we provide. We want you to receive all of the benefits offered by your insurance provider.


Insurance regulations require payment of these encounter fees at the time of service.


If you have a true medical emergency you should call 911. If you feel the problem is urgent, a telephone call to the physician with that statement is best so that the appropriate triage may be performed.

Medical Records

Should you need a copy of your medical records, please fill out our medical records release form to authorize the release of records and designate a recipient. There is a $25 fee for this service.

Medical Forms and Patient-Requested Letters

Charges to complete medical forms (driver’s license, assisted living, insurance, etc.) and patient-requested letters are not covered by insurance and are therefore the responsibility of the patient. Fees vary according to the length and complexity of the form or patient-requested letter and are determined by the physician

Prescription Refills

Please contact the pharmacy for all prescription refills. If authorization from a provider is necessary for the refill, the pharmacy will contact us. It is important that you contact the pharmacy several business days before you run out of medication to ensure enough time for authorization to be acquired and sent back to the pharmacy, and your prescription to be filled.

Telephone Calls

Routine telephone calls should be made between 9:00 AM and 4:30 PM Monday through Friday. The phones will be off during 12:00pm and 1:00pm for lunch. We have an answering service to answer emergency calls after hours. True medical emergencies that can not wait should prompt a 911 call.
