Appointments and Cancellations

Thank you for choosing Northwest Georgia Oncology Centers for patient-centered care for cancer and blood disorders.

If you were referred to us by another physician, your first appointment may already be scheduled at a location nearest you.

Hospitalization

If a patient is hospitalized, our physicians at this practice have privileges at Wellstar North Fulton Hospital. 

Insurance and Payments
Wellstar works hard to create lasting relationships with medical insurance companies to ensure you’re receiving the best possible care. As you receive cancer care and treatment here by Northwest Georgia Oncology physicians, Wellstar confirms your primary insurance coverage, explains your benefits and files insurance claims with your carrier. If your insurance plan requires a referral for office visits, a referral must be received prior to your visit. Payment is expected at the time of service for office visits and most plans require a co-payment at the time of service. For patients requiring additional financial assistance, an office representative will help develop a payment plan and file your insurance accordingly. If you require hospitalization, we will file primary insurance claims for any physician services provided to you while at the hospital. Our participation in insurance plans is subject to change. Please notify us if you expect a change to your insurance or if your address or phone number changes.
Prescription Refills
To better serve your prescription needs, Wellstar and Northwest Georgia Oncology Centers offer a specialty pharmacy at Wellstar Cancer Center at Kennestone Hospital serving patients from all of our locations to help expedite treatment. The pharmacy is staffed by a pharmacist and pharmacy technicians with expertise in oncology and hematology medications and resources. Specializing in oncology and hematology drugs, most are kept in stock to prevent treatment delay. We provide expedited service at the time of your appointment and checkout.
