OMB has given final regulatory clearance to CMS’s long-awaited final rule expanding the requirements suppliers of durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) must meet to establish and maintain Medicare billing privileges. The text of the rule is not available yet, but it could reach the Federal Register at any time. The rule will finalize CMS’s January 25, 2008 proposed rule that most notably would bar DMEPOS suppliers from sharing a practice location with another Medicare supplier, including physicians or other DMEPOS suppliers. The proposed version also would set minimum business hours for suppliers, require suppliers to obtain oxygen from a state-licensed oxygen supplier in applicable states, and prohibit suppliers from having tax delinquencies. The proposed rule also called for changes to current requirements, including: clarifying that the DMEPOS supplier itself must be licensed to provide licensed services; establishing additional physical facility standards and specifying that “closed door” businesses (i.e., suppliers providing services only to nursing home residents) must meet these standards; and excluding the use of cell phones and pagers to receive public calls during business hours.
