The US Department of Health and Human Services, Office of Inspector General (OIG) recently transmitted a memorandum to the Center for Medicaid and CHIP Services detailing the findings of the Massachusetts state auditor's report on the commonwealth’s controls around dual-eligible hospice patients and weaknesses related to election statements and potential MassHealth overpayments for curative items and services related to hospice patients that should have been covered by the hospices.

A longstanding source of frustration among providers facing overpayment determinations is the inconsistent application of statistical sampling and extrapolation by Medicare contractors.
