According to page 105 of the 2023 Comprehensive Guide to Medicaid Services and Administrative Claiming for the pay and chase method:
“If the probable existence of a third party cannot be established or third-party benefits are not available to pay the beneficiary’s medical expenses at the time the claim was filed, the State Medicaid agency will pay the full amount allowed under their payment schedule. If the existence of a third party is determined after the claim is paid, or benefits become available from a third party after the claim is paid, recovery for reimbursement is sought to the limit of legal liability within 60 days from the end of the month in which the existence of the third party is determined.”
Additionally, States may exempt certain items or services from third-party liability (TPL) requirements when submission of claims for those items or services would always result in denial because the general insurance industry does not cover them. CMS requires the State to have clear and convincing documentation of non-coverage by insurers (this documentation must be updated at least annually). If a State has documentation, there is no need to further verify by submitting claims because there would be no liable third party and Medicaid TPL rules would not come into play. The controlling regulation is found at 42 CFR 433.139(b)(1), which states, “The establishment of third party liability takes place when the agency receives confirmation from a provider or a third party resource indicating the extent of third-party liability.”
When non-coverage has been documented, the State may permit providers to use a specific code on the claim denoting non-coverage by the third party. This code could allow the Medicaid Management Information System (MMIS) to override the cost avoidance edit and pay the claim. The State would have to require providers to maintain documentation to substantiate non-coverage when using override codes and could conduct provider audits to ensure that the provider has appropriate documentation of non-coverage.
Section 1903(c) of the Act permits an exception to the TPL requirements for Medicaid-covered services included in a Medicaid eligible student’s IEP. This means that Medicaid will pay primary, or prior to federal IDEA funds for Medicaid-covered services listed in a student’s IEP. Although the Medicaid program pays first for covered IDEA services, these services are still subject to the TPL requirements applicable to any other services furnished under the State Medicaid program. The State Medicaid agency must still pursue payment for TPL as Medicaid is secondary to all other sources of payment. While this outlines the exception to Federal TPL requirements, States are required to pay and chase when it is cost-effective to do so.
