This paper identifies which types of patients and hospitals have abusive Medicare billings that are responsive to law enforcement. For a 20 percent random sample of elderly Medicare beneficiaries hospitalized from 1994-98 with one or more of six illnesses that are prone to abuse, we obtain longitudinal claims data linked with Social Security death records, hospital characteristics, and state/year-level anti-fraud enforcement efforts. We show that increased enforcement leads certain types of types of patients and hospitals to have lower billings, without adverse consequences for patients' health outcomes.
