Billing built for Ontario, CA
Ontario sits at the heart of the Inland Empire, where Medi-Cal managed care runs primarily through IEHP and Molina alongside Medicare and commercial plans. Because we are based here, our team works from the current IEHP provider claim resources every day — not a generic playbook — and understands the local plans, provider networks, and referral patterns Ontario practices deal with.
Our office is at 337 N Vineyard Ave, Suite 230, Ontario, CA 91764. Being local means same-time-zone, responsive communication and a partner who knows the Ontario and West-End Inland Empire market — from independent primary care to post-acute providers.
