Arizona Medical Billing Services for Independent Practices

Matrix Medical Billing is based in Mesa, Arizona, and has been serving practices since 2007. We bill for independent practices across the Phoenix metro and statewide. Our billers work in the United States, you'll know the people on your account by name, and our fee is based on what we collect, not what we bill.

Why Arizona practices work with Matrix

  • Based in Mesa, Arizona, with U.S. billers. Every biller on your account works in the United States. We don't send billing work overseas.

  • Paid on collections. Our percentage is based on what we collect, on a sliding scale. We don't get paid until you get paid.

  • No long-term contract. After an initial 60-day onboarding period, you're month to month. Either side can end the agreement with 30 days' written notice.

  • Your system, not ours. We work in your existing EHR and practice management system.
