Financial Policy

The role insurance carriers play in the delivery of patient care is a result of today's rapidly changing healthcare environment. Some insurance companies restrict us in certain ways. Examples of such restrictions include the medications we can prescribe, specialists you may be referred to, and the frequency and type of services we provide to you.

It is always the patient's responsibility to know exactly which services are covered by the insurance plan. If you have questions about your insurance provider's coverage, we encourage you to contact the customer service representative at your insurance company prior to your appointment.

Co-payments are required before seeing a physician or having any laboratory procedures performed in our office. Visa, MasterCard, check, and cash payments are accepted at all the family practice facilities.

If you do have insurance coverage, we will submit the claim to your insurance company. You may receive a bill in the mail reflecting any outstanding balance after insurance has paid on your claim. To remain in good standing, this bill should be paid within 30 days of the invoice date.

If you are uninsured at the time of service, you must pay your bill in full at the time services are rendered. If you have an HMO insurance that does not list one of our physicians as your Primary Care Physician (PCP), you must pay for services at the time of your visit. You may contact your customer service representative at your insurance company to change your PCP.

If you need help applying for insurance, please contact one of our Financial Counseling Team members at (585) 396-6720 or (585) 396-6015.

There are also payment options available for self-pay patients. Please ask the secretary how to arrange for these.
