Department of Health

Issued: April 18, 2012
Link to full audit report 2010-S-65

To determine whether the Department of Health's eMedNY system reasonably ensured that Medicaid claims were submitted by approved providers, were processed in accordance with requirements, and resulted in correct payments to the providers. The audit covered the period October 2010 through March 2011.

The Department of Health (Department) administers the State's Medicaid program. Medicaid claims are processed and paid by an automated system, eMedNY, which is overseen by the Department. When Medicaid claims are processed by eMedNY, they are subject to various automated edits. The purpose of the edits is to determine whether the claims are eligible for reimbursement and the amounts claimed for reimbursement are appropriate. During the six-month period ended March 31, 2011, eMedNY processed approximately 174 million claims resulting in payments to providers of about $25 billion.

Key Findings

  • Auditors identified almost $6.3 million in overpayments resulting from:
    • claims that were inappropriately billed because of incorrect Medicare information;
    • claims for inpatient stays for high (intensive) levels of care that should have been based on less costly "alternate" levels of care;
    • claims with questionable payments for durable medical equipment rentals;
    • incorrect neonatal claims; and
    • claims with overpayments for transportation and vision care.
  • Auditors took steps to recoup or stop more than $3.2 million of these overpayments. Auditors also found 6 providers who were charged with abusing Medicaid, Medicare or other health insurance systems. The Department promptly terminated 2 of these providers, but the remaining 4were still under review.

Key Recommendations

  • We made 16 recommendations to the Department to recover the remaining inappropriate Medicaid payments and improve controls in the overpayment areas we identified.
