Federal anti-healthcare fraud programs recovered less money in 2015 because of budget sequestration, according to a new report from the Department of Health and Human Services.

The Health Care Fraud and Abuse Control Program, a joint effort between HHS and the Department of Justice, recovered $2.4 billion in fiscal year 2015 according to the report, released last Friday. That’s nearly $1 billion less than the $3.3 billion recovered the previous year.

The drop can be explained by sequestration of mandatory funding in 2015, which left federal programs with “fewer resources” to combat healthcare fraud and abuse, the report said. The HCFAC program lost $22 million to sequestration in FY 2015, totaling to more than $74 million over the past three years.
