Medicaid Secondary to Medicare


To ensure the proper procedure is utilized when identifying specific denials received by Medicaid when they are secondary to Medicare.


At the time the claim balance is submitted to Medicaid as the secondary insurance to the primary payer, it is identified that Medicare’s reimbursement rate exceeds the maximum allowable from Medicaid. With this Medicaid will deny for “Payments adjusted due to the impact of the prior payer(s) adjudication including payments and/or adjustments” (OA23).

This will result in a zero ($0) dollar payment from Medicaid and the denial code reason of OA23.

At the time that this denial is identified, Clinicient will adjust the remaining balance as a contractual adjustment.
