HB4327 audit bill advances as Rep. Maura Hirschauer votes yes in 340B drug program review

Rep. Maura Hirschauer (D-49th) supported HB4327, legislation requiring an audit of Illinois's 340B Drug Discount Program participation, during the 104th General Assembly on May 31, 2026. According to the Illinois House, the bill passed with a 106-8 vote.

The official bill summary refers to the measure as: "AUDITOR GENERAL-340B AUDIT."

The following information draws from the actual bill language, with added explanation to clarify its content.

The bill tasks the Illinois auditor general with conducting a comprehensive audit, as soon as possible after the effective date, to evaluate 340B covered entities' participation in the federal 340B Drug Discount Program statewide. The review will include an analysis of profits from 340B medications, expenditures on third-party administrators, payments to pharmacy benefit managers and contract pharmacies, contractual drug ownership at contract pharmacy locations, markup averages for 340B-priced drugs, and the frequency with which patient discounts are delivered at the point of sale. A report with findings and recommendations must be submitted to the General Assembly.

The legislative status for HB4327 is recorded as 'Senate Committee Amendment No. 1 House Concurs.'

Hirschauer is a Colby College graduate with a Bachelor of Arts degree.

A member of the Democratic Party, Hirschauer was elected to the Illinois State House in 2021 to serve the 49th House District, succeeding former representative Karina Villa.

In Illinois, proposed bills go through a step-by-step legislative pathway beginning with introduction in either chamber, followed by committee consideration, floor debates, and votes in both the House and Senate before being sent to the governor for signature or veto. The General Assembly convenes biennially, and although legislators introduce thousands of bills each session, only a limited number ultimately become law.
