The FDA's June 30 deadline to issue final rules for unique barcodes on all medical devices came and went, with those new regulatory guidelines remaining in limbo. An FDA spokeswoman told ModernHealthcare.com that the rule is under "administrative review." As the story notes, device manufacturers asked for more time to prepare for the rollout, and they have questioned how the new requirements would promote public good. Patient groups say the system will help boost patient safety and reduce medical errors. Last November, AdvaMed told the FDA it wanted changes to make the plan more affordable to industry and more practical for companies, patients and providers. Story
