20 C.F.R. §§ 418.1320–418.1325

An initial determination is binding unless you request a reconsideration within the time period described in §§ 404.909 and 404.911 of this chapter or we revise the initial determination or issue a new initial determination.

If we make an income-related monthly adjustment amount determination for you for the effective year under subpart C of this part (Medicare Prescription Drug Coverage Income-Related Monthly Adjustment Amount), we will apply that income-related monthly adjustment amount determination under this subpart to determine your Part D income-related monthly adjustment amount for the same effective year. Therefore, if you become enrolled in Medicare Part B in the effective year after we make an income-related monthly adjustment amount determination about your Medicare prescription drug coverage, the income-related monthly adjustment amount determination for your Medicare prescription drug coverage will also be used to determine your Medicare Part B income-related monthly adjustment amount. Any change in your net benefit due will be accompanied by a letter explaining the change in your net benefit and your right to appeal the change.

If you are dissatisfied with our initial determination about your income-related monthly adjustment amount, you may request that we reconsider it. In addition, a person who shows that his or her rights may be adversely affected by the initial determination may request a reconsideration. We may accept requests for reconsideration that are filed by electronic or other means that we determine to be appropriate. Subject to the provisions of this section and § 418.1330, when you request a reconsideration, we will use the rules in §§ 404.907 through 404.922 of this chapter.
