Sen. Seth Lewis supports HB4327 for full audit of 340B program involvement

Sen. Seth Lewis (R-24th) supported HB4327, which mandates a comprehensive audit of 340B program participation, during the 104th General Assembly on May 31, 2026, the Illinois Senate reported. The bill received unanimous approval in the Senate with a 57-0 vote.

According to the official summary, the measure is titled: "AUDITOR GENERAL-340B AUDIT."

This overview is based on a review of the bill text, with clarifications included as needed.

Primarily, the legislation instructs the Illinois auditor general to promptly undertake a detailed audit examining the participation of 340B covered entities in the federal 340B Drug Discount Program. The evaluation must analyze profits from 340B drugs, expenditures involving third-party administrators, payments to pharmacy benefit managers and contract pharmacies, ownership structures at contract pharmacy sites, typical markups of 340B-priced drugs, and the frequency with which discounts benefit vulnerable patients at the point of sale. Findings and recommendations must be submitted to the General Assembly.

For HB4327, the action recorded was 'Third Reading - Passed.'

Lewis holds a BS from the University of Iowa, earned in 1991.

The Republican senator began serving in the Illinois State Senate in 2023, representing the 24th District after succeeding Suzy Glowiak.

Illinois bills progress through a multi-phase legislative process that involves introduction in the House or Senate, committee evaluation, floor discussions, and votes in both legislative chambers before moving to the governor for possible enactment or veto. The General Assembly meets on a two-year cycle with thousands of bills filed each session, though only a subset advance to become law.
