Under the resource-based system, we have developed practice expense relative value units specific to the facility and non-facility settings. Generally, under the resource-based system, the facility practice expense RVUs will be used for services performed in inpatient or outpatient hospital settings, emergency rooms, skilled nursing facilities, or ambulatory surgical centers (ASCs). The non-facility practice expense relative value units will be used for services furnished in all other settings. We did not develop non-facility practice expense relative value units for some services which, either by definition or in practice, are never (or rarely) performed in a non-facility setting. For example, by definition, the initial hospital care codes (CPT codes 99221-99223) are provided only in the hospital inpatient setting. Also, many major surgical procedures with a 90-day global period are almost always performed in the hospital inpatient setting. These facility-only codes are identified by a “NA” in the “NA Indicator” field.
