What is coordination of benefits?

When a member has more than one insurance plan, GEHA needs to know so we can determine how to coordinate your coverage to ensure you’re getting the most out of your plan.

One plan becomes your “primary” plan and will process your claims first. The “secondary” plan may pay toward the remaining charges. This process is called coordination of benefits.

I’m a GEHA dental member. Why is GEHA asking for information about my health plan?

The Federal Employees Dental and Vision Insurance Program (FEDVIP) requires the FEHB plan to be primary over the FEDVIP plan. This is known as “coordination of benefits.” Many FEHB plans have limited preventive dental benefits. When GEHA is secondary, our payment will be the lesser of 1) our regular benefit or 2) the remaining balance which when added to the primary carrier's payment will not exceed the dentist billed amount or the negotiated rate. In addition to benefits payable by your FEHB medical plan, you should let GEHA know if you or your covered dependents have other dental coverage.

How is it determined which plan is “primary” or “secondary”?

We apply guidelines from the National Association of Insurance Commissioners (NAIC).

The most common rules for determining the order of payment are the Non-Dependent/Dependent Rule, the Active/Inactive Rule and the Birthday Rule.

  • Non-dependent/Dependent Rule: The plan that covers an individual as an enrollee or subscriber is the primary payer over a plan that covers an individual as a dependent, for example, as a spouse.
  • Active/Inactive Rule: The plan that covers an individual as an active employee or as the dependent of an active employee is the primary payer over the plan that covers the individual as a retired or laid off employee or as the dependent of such an employee.
  • Birthday Rule: This rule determines whether a plan is primary or secondary for a dependent child who is covered by both parents' benefit plans and those parents live together. The plan covering the parent whose birthday (month and day only) falls first in a calendar year provides primary coverage for the child. If both parents have the same birthday, then the plan that has been in effect the longest pays as primary.


A different set of rules applies to a dependent child whose parents are divorced or separated or are not living together, whether or not they have ever been married:

  1. If a court decree states that one of the parents is responsible for the child's health care expenses/coverage ("health care coverage responsibility") and the plan covering that parent has actual knowledge of those terms, that plan is primary. If the responsible parent has no coverage for the child’s health care expenses, but that parent's spouse does, that parent's spouse's plan is the primary plan.
  2. If a court decree states that both parents are responsible for the child’s health care expenses/coverage, the Birthday Rule determines the order of benefits;
  3. If a court decree states that the parents have joint custody without specifying that one parent has health care coverage responsibility, the Birthday Rule determines the order of benefits; or
  4. If there is no court decree allocating health care coverage responsibility for the child, the order of benefits for the child is as follows:
    1. The plan covering the custodial parent;
    2. The plan covering the custodial parent's spouse;
    3. The plan covering the non-custodial parent; and then
    4. The plan covering the non-custodial parent's spouse.
  5. For additional information on NAIC rules regarding the coordinating of benefits, visit the NAIC website.

    How does the coordination of benefits happen?

    If it is determined that GEHA is the secondary plan, copies of the primary carrier’s Explanation of Benefits (EOB) forms will need to be submitted by you or your provider. Once we have a copy of the EOB, GEHA can determine our payment on the remaining balance.

    If the primary plan is a FEHB plan, GEHA will estimate benefits payable if the FEHB EOB is not received. The estimation of benefits is based on the dental benefits listed in the FEHB brochure.

    How does GEHA know who my FEHB carrier is?

    GEHA receives information every Open Season, through BENEFEDS, indicating the 3-digit FEHB Health Plan enrollment code. GEHA may request that you verify your health insurance plan annually or at the time of service. You may call or mail other coverage information or report it online at gehadental.com/cob.

    Can’t the plans just work it out? Why do I have to get involved?

    Most commercial plans only share protected health information with their members or providers.
