S.B. No. 1525 amends the Texas Insurance Code to enhance coverage for prescription drugs related to the treatment of neurodegenerative diseases, alongside autoimmune diseases and certain blood disorders. The bill modifies the heading of Subchapter N, Chapter 1369, to include "neurodegenerative diseases" and updates Section 1369.654 to limit health benefit plan issuers to requiring no more than one prior authorization annually for prescription drugs prescribed for these conditions. Additionally, it allows issuers to require prior authorization for new prescription drugs specifically for neurodegenerative diseases.

The changes in the law will take effect for health benefit plans that are delivered, issued for delivery, or renewed on or after January 1, 2026. Plans that are delivered or renewed before this date will continue to be governed by the previous law. The Act is set to take effect on September 1, 2025.
