conditions of coverage, and benefit levels and limitations with respect to persons
entitled to Medicare on the basis of ESRD, age, or disability for whom Medicare is

potential enrollees; and
• An explanation of the plan's allegation that it does not owe CMS any
amount CMS claims the plan owes as refund for conditional or mistaken Medicare
primary payments. The plan must include all information requested by the A/B
MAC or DME MAC.
