Increases the employee threshold for "large employer" classification from 100 to 150 eligible employees, changing the definition from "more than 100" to "more than 150" employees.

Allows employers issued small group health plans before January 1, 2026, with 51-150 employees to remain in the small group market for five years or elect to enter the large group market, with restrictions on switching back.

Requires carriers to submit two rate filings by July 1, 2025, demonstrating the impact on premiums for small group plans with fewer than 51 employees.

Includes a repeal provision if rate filings show that premiums for the majority of individuals in small group plans would increase by more than 3 percent after accounting for normal premium trends.
