(1) considered to be untrue if the statement or item does not conform to fact in any respect that is or may be significant to an enrollee of, or person considering enrollment in, a health care plan; and

(2) considered to be misleading, whether or not the statement or item is literally untrue, if, in the total context in which the statement is made or the item is communicated, the statement or item may be reasonably understood by a reasonable person who does not possess special knowledge regarding health care coverage as indicating:

(A) the inclusion of a benefit or advantage that does not exist and that is of possible significance to an enrollee of, or person considering enrollment in, a health care plan; or

(B) the absence of an exclusion, limitation, or disadvantage that does exist and that is of possible significance to an enrollee of, or person considering enrollment in, a health care plan.
