This bill amends Chapter 18, Title 41 of the Idaho Code by adding a new section, 41-1854, which establishes provisions regarding anticancer medications. It defines "anticancer medication" as any drug or biologic used to combat cancerous cells and outlines the requirements for health benefit plans that cover these medications. Specifically, the bill mandates that the copayment, deductible, or coinsurance for orally administered anticancer medications must not exceed that of injected or intravenously administered medications, or that out-of-pocket costs for orally administered medications do not exceed $250 for a 30-day supply.

Additionally, the bill clarifies that health benefit plans are not required to classify anticancer medications as a medical benefit and prohibits plans from increasing costs or reclassifying benefits related to these medications to comply with the new provisions. The bill declares an emergency, making it effective on July 1, 2026.
