defined under section 1935(c)(6) of the Act.

    (6) The PDP sponsor's contract is terminated by the PDP sponsor or

PDP plan is no longer offered in the area when the individual resides.
    (7) The individual is no longer eligible for the PDP because of a 
change in his or her place of residence to a location outside of the PDP 
region(s) in which the PDP is offered.
    (8) The individual demonstrates to CMS, in accordance with 
guidelines issued by CMS, that--

available under the plan;
