The measure passed the House and Senate last month with bipartisan support.
The current out-of-pocket limit for a 30-day supply of insulin has been $100 since January 2021, under a law passed by the Washington Legislature in 2020. That law is set to expire on Jan. 1, 2023, which is when the new law takes effect.
The new limit would end on Jan. 1, 2024. The extension is meant to give more time for a work group created in 2020 to finish its work to come up with a long-term solution for insulin costs.
