• Draft CY 2025 Part D Redesign Program Instructions Errata (February 13, 2024): We have identified a typographical error in an illustrative example in the Draft CY 2025 Part D Redesign Program Instructions. Specifically, in section 40, Policy for Drugs Not Subject to the Defined Standard Deductible, we provided a scenario on page 10 to illustrate how the policy would work. In that example, we incorrectly stated that the hypothetical beneficiary would have $550 in remaining TrOOP-eligible costs before the beneficiary satisfies the defined standard deductible. The correct amount of remaining TrOOP eligible costs is $390, not $550.
