Overall Conclusion

The audit concluded that eMedNY reasonably ensured Medicaid claims were submitted by approved providers, processed in accordance with Medicaid requirements, and paid correctly overall. However, improvements were needed in the processing of certain claim types, with over $11.5 million identified as improper payments during the 6-month period ended September 30, 2024; DOH recovered more than $2.6 million and was urged to continue to recover the remaining amount and strengthen controls.

Audit Scope

The audit covered the Department of Health’s eMedNY Medicaid claims processing system and its administration of the State’s Medicaid program, focusing on whether Medicaid claims were submitted by approved providers and processed in accordance with Medicaid requirements, and whether payments to providers were correct. The scope includes the 6-month period ended September 30, 2024 (April 1, 2024 through September 30, 2024) and certain claims going back to January 2022. During the period, eMedNY processed almost 249 million claims with payments totaling nearly $50.6 billion, in weekly cycles averaging about 9.6 million claims and $1.9 billion in payments. The audit examined both fee-for-service and managed care claim processing, the disenrollment and premium payment processes, and various policy areas such as primary payer designation, supplemental capitation payments for newborns and maternity, and the handling of provider sanctions. The audit employed non-statistical sampling (2,010 judgmental claims totaling about $170 million; 78 random pharmacy claims totaling about $2.9 million; and all claims related to comprehensive third-party coverage) and relied on data from the Medicaid Data Warehouse and eMedNY, among other sources.

AI Scope Summary

Assess the Department of Health’s eMedNY Medicaid claims processing controls to ensure claims are submitted by approved providers, processed per Medicaid rules, and paid correctly, for the 6-month period April 1–September 30, 2024 (with certain claims back to January 2022), and evaluate actions taken to recover improper payments and sanction noncompliant providers.

AI-Generated Insight

The Medicaid claims processing audit highlights the importance of robust, end-to-end controls across enrollment, eligibility, and claims adjudication systems. While the eMedNY platform largely functions as intended, targeted weaknesses in disenrollment timing, retroactive coverage, and data reporting for newborn and maternity claims generated substantial improper payments. The findings underscore the value of timely cross-system reconciliations, proactive monitoring of third-party payer interactions, and ongoing collaboration between DOH, OMIG, NYSOH, and investigative authorities to safeguard program integrity and maximize recoveries.
