Payment Options

We offer convenient payment options. We accept most insurance and will even file all the paperwork for you. We also accept Visa, MasterCard and Discover.

Payment is due when services are rendered, including HMOs, PPOs, Medicare and Medicaid co-payments and/or deductibles. Exceptions to this policy must be arranged in advance with the Patient Accounts Coordinator. Account balances that remain unpaid for over 90 days may be subject to collection efforts.

Insurance Information

We are dedicated to helping you process your insurance claims quickly and efficiently. You can help us immensely by ensuring that you have the following items with you when you arrive for your first visit:

  • Insurance verification or member ID card
  • Insurance carrier contact information
  • Group policy number
  • Co-payment schedule and credit card or cash for payment

As you might know, plans and coverage continually change with each insurance carrier. The more information you know about your plan, the easier it will be for us to verify and process your claim. Please let us know how we can make this process easier for you. Thank you for your cooperation.

We accept many types of insurance plans. Please call our office to verify your particular coverage or eligibility.
