We are in-network for all commercial insurance plans in our market including: Providence, Healthnet, PacificSource, Atrio, Aetna, BCBS Blue Cross Blue Shield, CIGNA, First Choice Health, Humana, MODA, Pacific Source, Samaritan Choice, United Health Care and all others in this geographical area. If your plan is not listed please feel free to call our Business Office Specialist to confirm acceptance of your plan. Please call Monday thru Thursday between 9am and 4pm with insurance questions.

It is always the patients responsibility to confirm specific coverage for their individual plan as insurance companies offer many plans and the coverage limits are specific to each plan type. Please call your insurance company customer representative to find out if a specific visit type or procedure is covered and what your responsibilities will be. We do require co-pays when applicable at each visit. Our Business Office Specialist can assist with determining what your visit type will be if you have any questions.

Our new patient team is available to help you determine what is required in order to schedule a new patient visit.

Please call our referral desk if you are a self referred patient.



We accept referrals from primary care physicians, other specialists, and self referrals for self pay patients and patients who's insurance does not require a referral to a see a specialist. Our professional staff is happy to answer any questions you may have related to becoming a patient in our practice.

Typically patients are referred by their primary care physician or other specialists by sending us your referral with relevant chart notes and any available lab results. Our providers review all incoming referrals and our scheduling staff coordinates the new visits. If prior authorizations are required by your insurance provider, those must be in place prior to scheduling. 
Patients are seen by appointment only. 

Please call our office to discuss your referral (including self referral), records (records we may request from your primary care or other referring office), insurance coverage (we do accept self-pay patients) and our admission policies and practices.

Existing Patients
Two way communication between clinical staff and patients is achieved by signing up for our secure patient portal. Lab result documents can be sent to you upon request, and non-emergency questions can be sent to the clinical team. We respectfully request that you call the office with any scheduling questions or concerns as we are unable to manage schedule changes thru the patient portal. Any appointment cancellations must be confirmed a minimum of 24 hours prior to your scheduled appointment so that other patients may take available spots.
