Dual Coverage

Having dual health insurance coverage means you're covered under two health insurance plans simultaneously. This typically occurs when someone has their own insurance through an employer and is also covered as a dependent on a spouse's or parent's plan, or when someone has both Medicare and supplemental coverage.


How Dual Coverage Works

When you have two insurance plans, Coordination of Benefits (COB) rules determine which plan pays first (primary) and which pays second (secondary):

  1. The primary insurance processes your claims first according to its terms.
  2. The secondary insurance then considers what remains unpaid.
  3. The secondary plan typically pays up to what it would have paid if it were primary, but won't exceed the actual charge.
  4. Total payments from both plans combined cannot exceed 100% of the allowed expenses.

Benefits of Dual Coverage

 

Lower Out-of-Pocket Costs

With proper coordination of benefits, dual coverage can reduce or eliminate your out-of-pocket expenses. After your primary insurance pays its portion, your secondary insurance may cover some or all of the remaining costs, including deductibles, copayments, and coinsurance.

Expanded Provider Networks

If the two plans have different networks, you may have access to a wider range of healthcare providers.

Additional Coverage for Services

One plan might cover services that the other doesn't, giving you more comprehensive overall coverage.

Important Considerations

Navigating Dual Coverage

To make the most of dual coverage:

  • Inform both insurance companies that you have other coverage
  • Understand which plan is primary and which is secondary
  • Keep detailed records of all claims and explanations of benefits
  • Double-check that providers submit claims to the correct primary insurer first
  • Review all explanations of benefits carefully to ensure proper coordination
