Oral Parity Legislation Effective January 1, 2026!

After more than a decade of sustained advocacy, oral parity legislation is now in effect as of January 1, 2026. 

In accordance with Michigan Public Act 170 of 2023, the copay and coinsurance for self-administered antineoplastic medications will be limited to $250 per month for a 30-day supply, after the deductible has been met.

Each year, beginning January 1, the Michigan Department of Insurance and Financial Services may adjust this cap based on the prescription drug index of the medical care component of the U.S. consumer price index. This change applies to commercial members with individual coverage or coverage through a fully insured group.

If you encounter patients who are not receiving the benefits required under this law, please reach out to MSHO at mmakarewicz@msho.org so we can address the issue.
