Enacts the "Louisiana Fair Insurance Modeling and Transparency Act" requiring insurers to disclose catastrophe model details (vendor, version, exposure data, geographic resolution) when filing residential property insurance rates

Mandates sensitivity analysis comparing modeled losses under post-mitigation conditions versus pre-mitigation conditions, with detailed analysis required for coastal regions, flood-prone areas, and areas with significant mitigation investments

Requires insurers to separate catastrophe modeling assumptions into wind-only, flood/storm surge, and combined loss components

Authorizes the Insurance Commissioner to approve or require geographically differentiated risk analysis based on factors including flood protection systems, elevation, drainage capacity, and proximity to water bodies

Requires the Department of Insurance to report to the Legislature every two years beginning January 1, 2027, on how catastrophe models account for mitigation infrastructure, premium impacts, and regional risk disparities
