Villa supports HB4327 ordering audit of Illinois' role in federal 340B Drug Discount Program

Sen. Karina Villa (D-25th) cast a Yes vote for HB4327 during the 104th General Assembly on May 31, 2026, which calls for auditing how the state engages with the federal 340B Drug Discount Program, according to the Illinois Senate. The measure received unanimous passage in the Senate with a 57-0 vote.

The text of the legislation summarizes HB4327 as follows: "AUDITOR GENERAL-340B AUDIT."

The summary below interprets the bill’s official language to clarify its primary elements.

The legislation directs the Illinois auditor general to begin, as soon as feasible after enactment, a systemic review of how 340B covered entities in the state engage with the federal 340B Drug Discount Program. Specific areas the audit must address include profits connected to 340B drugs, expenditures for third-party administrators, payments to contract pharmacies and pharmacy benefit managers, structures of drug ownership at contract pharmacy locations, the customary markup on drugs purchased with 340B pricing, and how frequently discounts reach vulnerable patients at the point of sale. The auditor general is required to provide findings and recommendations to the General Assembly.

The official action recorded for HB4327 was 'Third Reading - Passed.'

Villa, a Democrat, began serving in the Illinois State Senate in 2021, succeeding Jim Oberweis in representing the 25th Senate District.

Bills in Illinois progress through a detailed legislative process, starting with their introduction in either chamber, passing through committee discussions, floor debates, and chamber votes, and ending with the governor’s consideration for approval or veto. The General Assembly operates biennially, with thousands of bills introduced each cycle, yet only a select number are enacted into law.
