Relating to modification of certain prescription drug benefits and coverage offered by certain health benefit plans.

This bill (SB 959) sets rules for how health insurance companies in Texas can change prescription drug coverage under certain plans. It requires insurers to provide 60 days' written notice to the state, plan sponsors, and enrollees before modifying drug benefits, and limits changes to renewal periods with uniform application across similar plans. The bill specifically applies to most standard health benefit plans but excludes Medicare supplements, workers' compensation, dental/vision coverage, and self-funded ERISA plans. It aims to create clearer transparency for consumers about potential changes to their prescription drug coverage.
