[Code of Federal Regulations] [Title 20, Volume 2] [Revised as of April 1, 2006] From the U.S. Government Printing Office via GPO Access [CITE: 20CFR418] [Page 1184] TITLE 20--EMPLOYEES' BENEFITS CHAPTER III--SOCIAL SECURITY ADMINISTRATION PART 418_MEDICARE SUBSIDIES--Table of Contents Subpart D_Medicare Part D Subsidies Sec. 418.3201 Must you file an application to become eligible for a subsidy? Unless you are a person covered by Sec. 418.3105, in addition to meeting other requirements, you or your personal representative must file an application to become eligible for a subsidy. If you believe you may be eligible for a subsidy, you should file an application. Filing a subsidy application does not commit you to participate in the Part D program. Filing an application will: (a) Permit us to make a formal determination on your eligibility for the subsidy and whether you should receive a full or partial subsidy; (b) Assure that you can receive the subsidy for any months that you are eligible and are enrolled in a Medicare Part D plan or Medicare Advantage plan with prescription drug coverage; and (c) Give you the right to appeal if you disagree with our determination.
