Understanding Your Explanation of Benefits

Your Explanation of Benefits (EOB) is a paper or electronic statement provided by your dental insurance company, which breaks down any dental treatments or services that you have received. 

The EOB is different from a bill. It is sent to you after your dentist visit, and outlines your costs, the treatments that were covered under your dental plan, and treatments that may not have been covered and why.

Why Is Your EOB So Important?

After you receive your EOB, you will know what, if anything, you owe to your dentist. An EOB presents the opportunity to make sure you are being billed for a service or treatment you actually received, and that the amounts listed are within your expectations. Therefore, understanding the different parts of an EOB is critical to finding and avoiding billing errors. 

An EOB provides essential information, including but not limited to, treatments performed, dentist’s fees, insurance payments, amount you may owe for deductibles, co-pays, or procedures not covered by your policy, coordination of benefits information (if applicable), the portion of your annual maximum that has been used, and the amounts you have paid toward the deductible in the current benefit year.

How to Read Your Explanation of Benefits

An EOB from Delta Dental will typically include the following information:

  • Top of Your EOB: You will see a section that contains subscriber and member identification information, dentist name and the claim number. You might need this information to check on the status of a claim status.
  • Tooth #: This refers to the tooth number(s) treated. This ranges from 1-32 for adults and A through T for children.
  • Surface: This identifies the surface of the tooth that was treated. This could include the front side (M: mesial), back side (D: distal) or other areas of a tooth.
  • Date of Service: The date the procedure was performed.
  • Procedure Code: Also referred as the CDT Code (Current Dental Terminology Code), a set of codes used to identify the procedures performed at the dentist’s office.
  • Submitted Amount: This is the dollar amount the dentist submitted to your insurance company for a given procedure.
  • Max Allowable: This is the dollar amount that Delta Dental approved for the services you received based on the dentist’s agreement with Delta Dental.
  • Contract Allowed or Allowed Amount: This amount depends on your employer's contract with Delta Dental, as some employers may place a dollar limit on certain procedures. In most cases, the approved amount and allowed amount will be the same.
  • Deductible: The amount you must pay before your insurance benefit begins. 
  • % Copay or Payment Level %: The dollar amount or percentage your dental insurance plan will cover per procedure.  Tip: This is different than the flat copay that you typically pay during a physician visit for medical insurance.  
  • Patient Balance: The patient/member payment is the dollar amount you pay.
  • Delta Dental Payment: Delta Dental’s payment for the services provided.
  • Reference Code:  Explains any limitation on your insurance coverage for the procedure you received.
Other Terms That Your EOB Might Reference

These terms will not always be used in your Explanation of Benefits, but it is important to know their meaning in case they appear.

  • Procedure Description: Describes the treatments and procedures you received at the dentist’s office.
  • Claim Number: The number assigned to the claim that corresponds to the EOB.
  • Your Other Insurance Paid: The amount paid by any other insurance you may have.
  • Benefit Period: The period of time of your coverage. 
  • Annual Maximum: The maximum dollar amount your dental insurance will pay toward the cost of dental services and treatment. Tip: This is not the most you will pay out of pocket per year that you typically see in medical insurance plans.
  • Annual Maximum Used to Date: The amount of your plan maximum used to date during a benefit period. 
  • Overmax: The amount which exceeds your plan maximum during a given benefit period.
Frequently Asked Questions About Explanation of Benefits

Here are the answers to common questions about EOBs.

Is my explanation of benefits a bill?

No, an EOB is not a bill. On the most basic level, your EOB will provide a breakdown of the dental services that you received, the amount Delta Dental will pay to your dentist, and any portion you will be expected to pay the dental office. A bill for any amounts you may owe will come separately.

When will I receive my EOB?

The dentist will bill your dental insurance company after you’ve received dental treatment, and then you will receive an EOB, typically before you receive a bill from the dental office for any amount you may owe.
