In short

  • The county pays employee medical claims itself. An insurer covers only very large claims.1
  • Medical claims were about $24.9 million in fiscal 2025, up about 6% from the year before (our math).12
  • The county also covers most workers’ injury claims itself.3

Numbers marked “our math” are our estimates, not official figures. The notes show the inputs and the steps.

How it works

  • Self-funded health plan. The county pays claims for its full-time workers and their families. “Stop-loss” insurance covers claims above a set amount. An outside company handles the claims.1
  • Workers’ injury claims. The county pays these itself up to a limit for each incident. Insurance pays above $750,000 for law enforcement, jail and EMS workers, and above $500,000 for others. That has applied since Oct. 1, 2024.3 On Sept. 30, 2025, the county owed $1,012,090 on these claims. That counts claims not yet reported. All of it is due within a year.3
  • Other risks such as lawsuits, theft and storm damage are covered by a mix of self-insurance and regular insurance.3

  • Unpaid injury claims were about $1.0 million on Sept. 30, 2025. That includes an estimate for claims not yet reported.3
  • Settlements stayed within insurance. The report says settlements did not exceed coverage in fiscal 2025.3

The other side

  • Self-funding means the county carries the cost swings. When injury losses are more than the premiums collected, county funds make up the gap.3
  • The county faces a number of lawsuits. Its managers expect no major harm from them, so the report sets nothing aside for losses.4
  • The report does not show the health plan’s reserves or what employees pay toward it.

Questions to ask

  • How much does the county keep in reserve for a high-claims year?
  • How does the county set employee premiums compared with its own share?

What we still don’t know

  • Claims after Sept. 30, 2025.
