Setting Up Open Dental Frequency Limitations

When a patient comes in for a cleaning, you need to know immediately if their insurance will cover it based on their history. If you do not correctly configure open dental frequency limitations, you risk submitting claims that are automatically denied, forcing your front desk staff to spend hours on the phone resolving preventable issues.

Before You Start

Before configuring these limits, ensure you have the patient's insurance plan correctly entered in the Family Module. You should have the specific insurance carrier, group number, and plan type (e.g., PPO, HMO) already saved. It is also helpful to have the patient’s EOB or the insurance plan’s summary of benefits handy, as you will need to know the exact frequency rules (e.g., "twice per benefit year" or "once every six months") provided by the carrier.

Step-by-Step Instructions

Follow these steps to set up frequency rules for a specific insurance plan:

1. Go to the Family Module and select the patient.
2. Double-click on the insurance plan listed in the "Insurance" section to open the Edit Insurance Plan window.
3. Click the Benefits/Coverages button. This opens the Benefits window.
4. Click the Add button to create a new benefit entry.
5. In the Category dropdown, select the procedure category (e.g., "Diagnostic" for exams or "Preventive" for cleanings).
6. In the Benefit Type dropdown, select "Frequency."
7. In the Quantity field, enter the number of times the procedure is allowed (e.g., "2").
8. In the Time Period dropdown, select the appropriate interval (e.g., "Calendar Year," "Service Year," or "Rolling 12 Months").
9. Click OK to save the benefit.
10. Click OK again to close the Edit Insurance Plan window.

Once saved, Open Dental will use these settings to warn you if a procedure is scheduled that exceeds the frequency limit.

Common Mistakes

The most common error is selecting the wrong "Time Period." If you select "Calendar Year" when the insurance actually follows a "Rolling 12 Months" policy, the system will not flag the claim correctly, leading to unexpected denials. Another mistake is applying the frequency limit to the entire "General" category instead of a specific sub-category like "Prophylaxis." This can cause the system to incorrectly block other necessary diagnostic procedures because it thinks the patient has already reached their limit for the entire category.

Related Scenarios

If you need to verify if a patient has already met their frequency limit for a specific procedure, you can check their history in the Account Module.

If a claim is denied due to a frequency limitation, you may need to adjust the claim status or write off the balance.
