Medicaid Fraud Control Units (MFCUs) are state agencies that investigate and prosecute health care provider fraud, using billing data to decide who to investigate. In particular, providers that submit a large number of claims for a set of fraud prone services are more likely to be investigated. We study the effect of within-state changes in MFCU spending on enforcement outcomes and hospital treatment intensity for fraud prone health conditions in the Medicaid population. We find that increases in MFCU spending substantially increase fraud enforcement actions (investigations, convictions, recoveries). In contrast, MFCU spending increases do not generate substantial changes in treatment intensity for fraud prone health conditions. We find no evidence that MFCUs with expanded budgets investigate less severe cases on the margin.

我们应该为警察医疗欺诈做更多的事情吗？有关扩大执法的预期和非预期后果的证据

医疗补助欺诈控制单元（MFCU）是州机构，负责调查和起诉医疗保健提供者欺诈，并使用计费数据来决定调查对象。尤其是，针对一组易于欺诈的服务提交大量索赔的提供者更有可能受到调查。我们研究了MFCU支出的州内变化对医疗补助人群中容易发生欺诈的健康状况的强制执行结果和医院治疗强度的影响。我们发现，MFCU支出的增加大大增加了欺诈执法行动（调查，定罪，追偿）。相比之下，MFCU支出的增加并不会在容易发生欺诈的健康状况下对治疗强度产生实质性变化。我们发现没有证据表明预算扩大的MFCU在边缘上调查较轻的案件。
