I have a question for the group… How are service units determined for DME? I am looking at the CMS website and found an MUE table for the ceiling and floor prices for certain codes however nothing explicitly talking about how to calculate service units for a code, maximum amount of service units for a code, etc. My understanding of DME units is that the provider bills for the amount of days that they expect the member to need the equipment unless otherwise specified. For example, wheelchair use would be billed per day so if the member needed it all year long, the provider would bill 365 for units to cover the year. Am I on the correct track?
