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

HB 4674 modifies Texas health benefit plans' prescription drug coverage rules. It allows health plan issuers to change drug coverage only at renewal time, requires uniform application across similar plans, and mandates 60 days' written notice to the commissioner, plan sponsors, and enrollees before changes take effect. The bill specifically affects health benefit plans offering prescription drug coverage, excluding certain exceptions like disease-specific plans, dental/vision coverage, Medicare supplements, workers' compensation, and self-funded plans. These changes aim to standardize how coverage modifications are implemented while providing notice to affected parties. The bill is currently in the Insurance Committee for review.
