Gynecologic Surgery

Dr. Parker is a highly skilled gynecologic surgeon. He has spent many years in extensive post-residency training in order to achieve special expertise in advanced laparoscopic and hysteroscopic surgery and he is often called upon to teach these procedures to other gynecologists in the United States and abroad. Our office provides special assistance to help schedule surgery.

How We Help You with Insurance Billing

Whether your surgery or procedure is done in the hospital, surgery center, or in our office, we will bill your insurance company.  We will request a deposit from you before the procedure and then bill you for any balance remaining after payment by your insurance.  Sixty days after we have billed your insurance, we require payment in full of any remaining balance.

Cynthia, our office manager, will obtain pre-authorization for surgery from your insurance company.  She is also available to help you with billing questions, as is Jeanne at our billing company.

For office visits, we ask for payment in full at the time of the visit.  We will give you a form that should be submitted to your insurance company.  The insurance company then reimburses you directly.  

Nurse Practitioners

We are pleased to have certified nurse practitioners as an integral part of our health care team. These highly trained gynecologic health care providers are available for most problems that can be cared for in the office including annual check-ups, breast exams, menopause counseling, contraceptive counseling and vaginal or bladder infections. Appointments with the nurse practitioner are available during regular office hours and Saturday mornings.
