How to Establish Care at One of the Primary Care Clinics
If you would like to be seen by one of our campus physicians and have not yet registered, you can start by filling out the New Patient Form and submitting a completed form to the New Patient Coordinator. For your convenience, you can also complete this form over the phone by calling 509.769.2014.
New patients are asked to fully complete a few very important forms so that we have the information we need to give you the best medical care. Once your application has been processed, our staff will send you a welcome packet to complete with the date and time of your appointment. We know your time is valuable; if you would prefer, we will contact you at a convenient time for you by filling out the contact form here.
Your First Appointment
Please bring your medications in the original bottles with you to your first appointment as well. If you need refills, please be prepared to allow 72 hours for our staff to process refill requests.
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. If you have questions if one of our providers is "in network" for your health insurance plan, please contact your insurance company directly or you may contact one of our Patient Financial Counselors at 509.758.4652 (Option 1).
