Lawsuit Targets 18% Interest Rate Charged by Marshall’s Former Practice
A class-action suit filed in Kansas state court accuses former obstetrics-gynecology practice Heartland Regional OBGYN—co-owned by Republican Sen. Roger Marshall—with charging an 18 percent annual interest rate on unpaid medical bills. The complaint alleges the rate exceeds the 15 percent ceiling set by Kansas law, except where a higher rate is expressly stipulated in a pre-existing contract. The filing also claims the practice’s collection tactics led to a former patient’s arrest on three occasions.
02
Background: From Private Practice to Senate Campaign
Marshall practiced obstetrics-gynecology in private practice before entering politics. During that time, the clinic reportedly charged the 18 percent rate primarily to low-income, uninsured, or underinsured mothers. When the issue first emerged, Marshall described the billing approach as “very common.” An analysis by *The Kansas City Star* of roughly 150 Kansas medical-debt lawsuits found Marshall’s 18 percent rate to be the highest among those practices.
03
Impact on the 2026 Kansas Senate Contest
The lawsuit has become a focal point in what was once considered a safe Republican seat. The controversy coincided with other challenges to Marshall’s candidacy, including questions about his residency, an unpaid bakery bill, and campaign-finance disputes. Early polling showed the Democratic challenger, Rev. Adam Hamilton, gaining a slight edge after the Democratic campaign highlighted the debt-collection allegations in advertising. The story’s resonance was amplified when President Donald Trump and Vice President J.D. Vance traveled to Kansas to campaign for Marshall, yet the effort has not reversed the polling trend.

Official Responses
Marshall’s legal team has maintained that the interest rates and collection methods are lawful and consistent with industry norms. The senator himself has reiterated that his business practices were standard for the region. No court ruling on the merits has been issued yet.
