Analysis: Marshall's 18% Medical Debt Interest Rate Exceeds All Other Kansas Providers

Key points

• The Star’s review of roughly 150 Kansas medical practices found that Marshall’s 18% interest rate was the highest, with most providers charging no more than 12%.
• Court records indicate that 81 former patients were arrested after missing debt collection hearings, and bond money was sometimes turned over to the doctor.
• Marshall co-sponsored the Patients Deserve Price Tags Act, which passed committee 21-1 but was blocked from full Senate adoption by Sen. Rand Paul.
• Legal experts are divided on whether Kansas’s 15% interest cap applies to medical debt, with some arguing it only regulates lenders.
• Marshall’s campaign declined to comment on whether interest rates were disclosed to patients before care was provided.

Background

This story follows earlier coverage of the intense 2026 Kansas Senate race between Marshall and Rev. Adam Hamilton, where debt collection practices have become a central campaign issue. It also follows reports from September 2026 regarding Marshall’s request for Hamilton to apologize for ads highlighting these practices.

Why it matters

The findings highlight a potential conflict between Marshall’s advocacy for healthcare transparency and his own business practices, raising questions about consumer protection laws and the enforcement of medical debt in civil courts.

What to watch

The Senate is currently in recess, delaying a vote on the Patients Deserve Price Tags Act until after the election. Marshall’s campaign has not responded to inquiries regarding the legality of the 18% interest rate or its disclosure to patients.
