I Googled it. Here is what I found this morning...

Here is an explation. https://old-prod.asco.org/sites/new-www.asco.org/files/content-files/advocacy-and-policy/documents/2021-AccumulatorsPolicyBrief.pdf

And here is a section of this page: https://www.crohnscolitisfoundation.org/managing-the-cost-of-ibd/hot-topic-copay-accumulator-maximizer-programs#:~:text=As%20of%20summer%202023%2C%2019,as%20well%20as%20Puerto%20Rico.

"Some states have banned copay accumulators. As of summer 2023, 19 states have banned copay accumulators: Arizona, Arkansas, Colorado, Connecticut, Delaware, Georgia, Illinois, Kentucky, Louisiana, Maine, New Mexico, New York, North Carolina, Oklahoma, Tennessee, Texas, Virginia, Washington, and West Virginia, as well as Puerto Rico. However, the laws may not apply to the newer copay maximizer programs.
If you live in a state that has NOT banned copay accumulators, be an advocate:
Contact your House Representative
Contact your state's insurance department
Call your insurer to ask questions
Tell your employer! Your employer might not be aware they signed up for this program or how it negatively affects their employees."
