Relating to patient data maintained by pharmacy benefit managers.

This bill prohibits pharmacy benefit managers (PBMs) from storing or processing patient data for Texas residents outside the United States. It directly affects PBMs operating in Texas by requiring all such data to remain within U.S. borders, as specified in new Section 4151.1531 of the Insurance Code. The law takes effect September 1, 2025, aiming to keep patient health information under U.S. jurisdiction. This is a security-focused requirement with no exemptions or additional provisions.
