June 24th ,2026Industry Policies

Key Changes Under the Inflation Reduction Act

The Centers for Medicare & Medicaid Services (CMS) has released the final guidance for the 2027 Medicare Part D benefit year, implementing several provisions of the Inflation Reduction Act. These changes aim to reduce prescription drug costs for millions of Medicare beneficiaries.

Major Policy Updates

  • $2,000 Annual Out-of-Pocket Cap: Beginning January 1, 2027, Medicare Part D enrollees will have their annual out-of-pocket spending on covered prescription drugs capped at $2,000. Once the cap is reached, the plan pays 100% of covered drug costs for the remainder of the year.
  • Expanded Drug Coverage: Part D plans must now cover a broader range of medications in six protected classes, including immunosuppressants, antidepressants, and antiretroviral drugs, with limited use of prior authorization and step therapy.
  • Monthly Payment Option: Beneficiaries can opt to pay their out-of-pocket costs in monthly installments rather than all at once at the pharmacy counter.
  • Insulin Price Cap: The $35 monthly cap on insulin costs, which took effect in 2024, will continue through 2027 and beyond.

Impact on Community Pharmacies

Pharmacies will need to update their point-of-sale systems to accommodate the new cap calculation and installment payment options. We also anticipate increased patient inquiries about plan coverage and formulary changes.
