AHCCCS patients must provide any other information to the office at time of service. Any insurance plan that is a commercial, private, employer sponsored or exchange plan is considered primary to your AHCCCS plan and AHCCCS requires that we bill that insurance prior to AHCCCS. If we do not bill the primary insurance first, AHCCCS will not pay the patient's claims. Once we bill the primary insurance any amount applied to patient responsibility will be billed to your AHCCCS plan. If it is an AHCCCS covered service, they will pay the balance of the claim on your behalf.
