The U.S. Department of Justice has declined to intervene in four whistleblower lawsuits accusing a hospice provider of routinely admitting patients who were not eligible for the service under Medicare.

Legal experts, however, warned against reading too much into the DOJ’s decision to not intervene in the case against Heartland Hospice, noting that the agency intervenes in just a small percentage of the more than 700 new whistleblower cases it receives each year.
