A federal appeals court revived two doctors’ False Claims Act lawsuit against a medical device manufacturer on Wednesday accused of making faulty hip implants.

The U.S. Court of Appeals for the First Circuit remanded the case to the U.S. District Court for the District of Massachusetts on the allegations that DePuy Orthopaedics, owned by Johnson & Johnson, sold defective hip implants to doctors who then sought government reimbursement through Medicaid and other programs.
