Scheduling an Appointment

Patients are seen by appointment only. Patients should call early in the day to ensure they will be accommodated. For urgent care needs, patients may be seen by their primary care physician. If their primary care physician is unavailable, another physician in the same department designated to see urgent care cases will attend to the patient. Our state-of-the-art electronic medical records system enables physicians to access important patient information in a timely manner.

Should the medical need arise, primary care physicians will refer patients for specialty care.

Contacting Your Physician

Each physician establishes his or her own policies regarding telephone calls. In general, our physicians are not available to take calls during patient hours. Phone calls will be returned promptly by either the physician or a physician representative during breaks in the schedule, or after hours. After-hours calls will be connected to our answering service, which will contact a physician for you.

Medical attention is available 24 hours a day, 7 days a week.

Payment Options

Before your visit, please understand your insurance plan requirements and what services your plan covers, including routine preventive care. Non-covered services are the financial responsibility of the patient.

For patients with participating managed care plans, we require payment of the co-payment at the time of your visit. For patients with commercial insurance plans, full payment of the visit is required.

Mount Sinai Doctors Long Island accepts cash, personal checks, credit cards, and debit cards. Please notify our Central Registration staff of any changes to your insurance plan, as well as changes to your address or telephone number.
