How Coordination of Benefits Works

Coordination of benefits helps determine how eligible claims are handled when a person has coverage under more than one plan. It does not mean the person can be reimbursed twice for the same expense. The submission order and documentation depend on the applicable rules.

When Two Benefits Plans May Apply

An employee may have workplace coverage and access through a spouse or another arrangement. Each plan still applies its own eligible-expense and maximum provisions. Having a second plan does not make an excluded expense automatically eligible under either contract.

Claim Submission Order and Plan Rules

Ask the insurers or administrators which plan should receive the claim first. The answer can depend on who incurred the expense and their relationship to each plan. Avoid relying on a general rule without checking unusual household, dependent or custody circumstances.

Spousal and Dependent Coverage

Coverage for spouses and children may involve different submission rules from claims for the employee. Keep dependent information current. If family circumstances change, notify the relevant providers promptly so claims are not processed using outdated records.

Reimbursement Limits and Remaining Balances

After the first plan assesses a claim, the second may consider an eligible unpaid balance under its own rules. Total reimbursement is limited by the applicable arrangements and expense. A claim remaining partly unpaid does not prove the second plan must cover the rest.

What Employees Should Ask Their Insurers

Employees should ask about order of submission, required explanation-of-benefits documents, electronic coordination and deadlines. The employer can provide contacts and general instructions without collecting the underlying clinical information.
