Blair-Sherlock backs bill to audit Illinois’ role in 340B Drug Discount Program

Rep. Diane Blair-Sherlock (D-46th) supported HB4327 on May 31, 2026, during the 104th General Assembly, according to the Illinois House. The bill, which calls for an audit of Illinois’ role in the 340B Drug Discount Program, passed the House with a 106-8 vote.

The bill summary states: "AUDITOR GENERAL-340B AUDIT."

Below is a summary based on the actual wording of the legislation, which may feature clarifications for greater understanding.

Essentially, the bill tasks the Illinois auditor general with conducting a full review, after the effective date of the law, of state 340B cover entities’ participation in the federal 340B Drug Discount Program. The audit will examine profits from 340B medications, third-party administrator expenditures, disbursements to pharmacy benefit managers and contract pharmacies, drug ownership models at contract pharmacy sites, standard markups for 340B-priced drugs, and the frequency with which discounts directly reach vulnerable patients at the point of sale. Findings and recommendations are to be presented to the General Assembly.

The legislative action taken on HB4327 was 'Senate Committee Amendment No. 1 House Concurs'.

Blair-Sherlock holds an associate’s degree from the College of DuPage (1985), a bachelor's degree from Northern Illinois University (1987), and earned her JD at John Marshall Law School in 1993.

A member of the Democratic Party, Blair-Sherlock won election to the Illinois State House in 2023, representing District 46 after Deborah Conroy’s departure from the seat.

In Illinois, the progress of bills follows a multi-step legislative process starting with introduction in either chamber, proceeding through committee consideration, debates, and votes in both the House and Senate, then sent to the governor for endorsement or rejection. The General Assembly meets on a biennial timetable, with thousands of bills introduced each session and only a limited portion passed into law.
