The Winston-Salem Journal cites a report that says at least 25 patients had faulty pathology laboratory test results at Wake Forest Baptist Medical Center.
The Centers for Medicare & Medicaid Services review says two patients underwent lumpectomies and radiation and one underwent a lumpectomy and mastectomy before learning they didn't have cancer.
Medicare officials say 19 had erroneous test results that didn't ultimately affect treatment. An initial report had only identified four potentially misdiagnosed patients.
The hospital has until Thursday to submit a corrective plan to CMS. Inpatient Medicare billing privileges could be suspended if issues aren't resolved.
