All DX-rated orders have equal priority with each other and take precedence over DO-rated orders and unrated orders. (For resolution of conflicts among rated orders of equal priority, see § 101.34(c).)
(3) In addition, a Directive regarding priority treatment for a given item issued by the Department of Health and Human Services for that item takes precedence over any DX-rated order, DO-rated order, or unrated order, as stipulated in the Directive. (For a full discussion of Directives, see § 101. 62.
