How is the secondary insurance billed after the primary plan?

Billing the secondary insurance after the primary plan typically involves resubmitting the claim. This process occurs after the primary insurance company has processed the claim and provided an Explanation of Benefits (EOB). The EOB details the amount paid, any adjustments made, and the patient's responsibility.

For the secondary claim, the provider usually needs to submit the claim again with the primary payer’s EOB attached to ensure that the secondary insurer has the necessary information to process the claim appropriately. This resubmission allows the secondary insurance to consider any remaining balances, ensuring the patient receives the appropriate benefits based on their policy.

The other options describe different actions that do not adequately represent the standard procedure for billing secondary insurance. Direct billing and notifying the patient do not effectively facilitate the claims process, while sending a summary notice is not a standard step in preparing a claim for secondary insurance billing.
