Secondary Claim Billing

Secondary claim billing refers to the process of submitting a claim to a secondary payer after the primary payer has processed the claim. This occurs when a patient has multiple insurance plans, such as Medicare and a supplemental plan, or when a patient's primary plan does not cover certain services. In these cases, the secondary payer may cover some or all of the remaining balance. For instance, if a patient's primary plan pays $500 for a service and the secondary plan covers 80% of the remaining balance, the practice can submit a secondary claim to the secondary payer to recover the additional $400.

The key to successful secondary claim billing is accurate and timely submission of claims. Practices must ensure that they have the necessary information, including the patient's insurance details and the primary payer's explanation of benefits (EOB). They must also follow the correct billing procedures, including using the correct codes and modifiers. For example, when submitting a secondary claim, practices must use the CO-22 code to indicate that another payer is primary. Failure to use the correct codes can result in denied claims and lost revenue.

Identifying crossover claims is crucial to ensuring that practices do not leave money uncollected. One way to identify these claims is to review the primary payer's EOB. The EOB will indicate if there is a balance remaining after the primary payer's payment. Practices can also use claims processing software to identify crossover claims and automate the submission process. For instance, our practice uses a billing software that flags claims that require secondary billing, allowing us to quickly and easily identify and submit these claims.

Another way to identify crossover claims is to review patient insurance information. Practices should verify patient insurance details at each visit to ensure that they have the most up-to-date information. This includes confirming primary and secondary insurance plans, as well as verifying coverage for specific services. By staying on top of patient insurance information, practices can reduce the risk of missed crossover claims and ensure that they are submitting all eligible claims to secondary payers.

Secondary claim billing can be complex and time-consuming, and practices often face several challenges when processing these claims. One common challenge is ensuring that claims are submitted correctly and in a timely manner. Practices must follow the correct billing procedures, including using the correct codes and modifiers, and submitting claims within the required timeframe. For example, if a practice fails to submit a secondary claim within 90 days of the primary payer's payment, the claim may be denied.

Another challenge is handling denials and appeals. If a secondary claim is denied, practices must review the denial reason and take corrective action to resubmit the claim. This may involve providing additional documentation or correcting coding errors. For instance, if a claim is denied due to a missing modifier, the practice must add the modifier and resubmit the claim. By understanding the common challenges in secondary claim billing, practices can develop strategies to overcome these obstacles and ensure that they are recovering all eligible revenue.
