The Know the Lowest Price Act of 2018 amends the Social Security Act to stop Medicare Part D and Medicare Advantage prescription drug plans from blocking pharmacies from sharing price information. It requires plan sponsors to allow pharmacies to tell enrollees how the plan’s negotiated price or copayment compares to a lower price the enrollee could get without using insurance. The rule applies to all Medicare prescription drug and MA‑PD plans and takes effect for plan years beginning on or after January 1, 2020.

Key Provisions

  • Adds a new subsection that prohibits Medicare prescription drug plan sponsors and Medicare Advantage organizations from restricting or penalizing pharmacies that inform enrollees about price differences between the plan’s cost and a lower out‑of‑pocket price.
  • Requires that each Medicare Part D or MA‑PD plan ensure pharmacies can share this price information with beneficiaries.
  • The prohibition applies to plan years starting on or after January 1, 2020.
