Overpayments for Medicare
Part C Coinsurance Charges (Issued 9/26/12)
To identify Medicaid overpayments made to medical providers for services rendered to recipients enrolled in a Healthfirst Medicare Advantage Plan. The audit covers the period July 1, 2006 through September 30, 2011.
Medicare Advantage Plans, also known as Medicare Part C (or Medicare Managed Care), are health plan options available to Medicare enrollees. Persons who join a Medicare Advantage Plan receive their Medicare benefits through a health plan, which has networks of participating providers that the plan reimburses directly. Medicare Advantage Plan enrollees may be responsible for cost-sharing liabilities such as deductibles and coinsurance. However, these liabilities may be paid by Medicaid if the individual is also enrolled in Medicaid. When this occurs, plan providers bill Medicaid directly for enrollees' cost-sharing liabilities.
Healthfirst is one of the largest Medicare Advantage organizations in New York, offering individuals different health care options under several Medicare Advantage Plans. During the audit period, Medicaid paid about 64,000 Medicaid claims (totaling $5.6 million) for clinic services provided to persons enrolled in a Healthfirst Medicare Advantage Plan.
- Healthfirst misreported the cost-sharing liabilities of Medicaid recipients to some of its healthcare providers. As a result, 14 providers billed excessive amounts of coinsurance on 497 Medicaid claims for clinic services. Because of the excessive claims, Medicaid made overpayments totaling $699,258 to the providers. Healthfirst has taken actions to prevent further errant claims and overpayments.
- As a result of our audit, plan providers submitted claim adjustments to reimburse Medicaid for some of the overpayments we identified. At the time our audit fieldwork was completed, providers submitted adjustments for 126 (of the 497) errant claims, and Medicaid had recovered $195,835.
- Review the remaining 371 errant claims and the related $503,423 in Medicaid overpayments identified in this report and recover funds where appropriate.
