CMS has proposed a series of revisions to its August 2006 quality standards for suppliers of durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS). Among other things, the revised standards would: require suppliers to notify the prescriber within five days if the supplier cannot provide the prescribed equipment; strengthen infection control requirements; require suppliers to take steps to prevent the use of adulterated, counterfeit, or misbranded products; expand documentation requirements for mail-order items; and revise specific power wheelchair and orthotics/prosthetics standards. Comments will be accepted until March 18.
