Do health care providers need to determine if an otherwise uninsured individual is Medicaid eligible?

Providers must verify and attest that to the best of the provider's knowledge at the time of claim submission, the patient was uninsured at the time the services were provided. For claims for COVID-19 testing and testing-related items and services, treatment of positive cases of COVID-19, and/or vaccine administration, this means that the patient did not have any health care coverage. Providers may submit a claim for uninsured individuals before Medicaid eligibility determination is complete. However, if the provider learns that the individual is retroactively enrolled in Medicaid as of the date of service, the provider must return the payment to HRSA.
