We are happy to file dental insurance claims for you. Dental benefit plans can vary from company to company with different procedures covered or not covered. Insurance companies base the amounts that they will pay toward your dental treatment on restricted fee schedules related to premium payments and geographical location. In other words, your insurance plan will pay only what it allows for each service, regardless of what the actual fee might be. Deductibles and co-payments are typically built into most plans and state law strictly regulates their required payment. Both our office and you as the policy beneficiary can be prosecuted if deductibles and co-payments are not collected. Your Employee Benefits Director can usually help you become familiar with your plan and its restrictions.

Financial Options For Our Patients:

  • Cash/Check (5% Discount)

  • Major Credit Card (3% Discount)

  • Payment Plans

  • Care Credit (Nationwide Healthcare Financing)

We Will:

  1. Complete your insurance claim forms and submit them to your carrier within 24 hours of treatment.

  2. Use current American Dental Association coding for correct reporting of procedures.

  3. Accept direct payment from your carrier if allowed under your insurance contract.

  4. If necessary, file your insurance a second time within a 60-day period.

We expect that you will:

  1. Pay fees not covered by your plan at the time of treatment, or establish a payment schedule

  2. Provide Drs. Krueger, Borja, and Minnema with necessary information concerning your insurance coverage to allow to correct filing of claims.

  3. Understand that your plan is a contract between you and your employer and the insurance carrier. We will do all that we can to facilitate claims payment, but we do not have the power to make your plan pay.

  4. Remit to this office within 30 days any payment received by you directly from the insurance carrier.

  5. Pay any account balance not paid by insurance after 2 billing attempts.

We thank you for choosing Preferred Dental Partners. We will do all that we can to help you obtain the benefits specified by your insurance contract.
