{"data":{"id":"us/20-cfr-418.2322","jurisdiction":"us","citation":"20 CFR 418.2322","heading":"How will a Medicare Part B income-related monthly adjustment amount determination for the effective year affect your Medicare prescription drug coverage?","body":"If we make an income-related monthly adjustment amount determination for you for the effective year under subpart B of this part (Medicare Part B 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 obtain Medicare prescription drug coverage in the effective year after we make an income-related monthly adjustment amount determination about your Medicare Part B, the income-related monthly adjustment amount determination we made for your Medicare Part B will also apply to your Medicare prescription drug coverage. 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.","path":["Title 20—Employees' Benefits","CHAPTER III—SOCIAL SECURITY ADMINISTRATION","PART 418—MEDICARE SUBSIDIES","Subpart C—Income-Related Monthly Adjustments to Medicare Prescription Drug Coverage Premiums"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-20.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:24:45Z","sha256":"931351d7d9bc2861782dbc6c217eec698994fcd7f6d36c25ea400e6349401830","source_id":"us-cfr","stale":true,"prev":"us/20-cfr-418.2320","next":"us/20-cfr-418.2325"},"notice":"GroundRules: Original legal text.
