Late arrival for your scheduled appointment may result in having your appointment rescheduled. Please arrive on time as we are committed to adhering to our schedule as closely as possible.
All commercial insurances will be billed for you, applicable co-pays are due at the time of your visit. If we are not in your insurance company’s preferred network, your insurance benefits may not pay us as they would an in-network provider and you will be responsible for the difference. If you are a self-pay patient, payment is due at the time of service.
We accept most types of insurance at Tri-State Memorial Hospital & Medical Campus.
