Learn how the AI-generated research projects were createdOverall Conclusion
For our audit period, the Maine Department of Health and Human Services’s FFS Medicaid payments for rehabilitative and community support services provided to children diagnosed with autism included improper and potentially improper payments. Improper payments totaled at least $45.6 million ($28.7 million Federal share) and potentially improper payments totaled about $22.4 million ($14.2 million Federal share). The issues stemmed from a lack of statewide postpayment reviews, insufficient guidance to providers on documentation, and inconsistent adherence to documentation requirements, which could affect the quality of care.
