Money already spent or billed for diagnosis, treatment, and recovery after an injury is called past medical expenses.

These are the medical costs that have already happened by the time a claim is evaluated, not care that may be needed later. They can include ambulance charges, emergency room care, hospital stays, surgery, X-rays, MRIs, prescriptions, follow-up visits, physical therapy, and other treatment that was reasonably necessary because of the accident. After a crash on Highway 55 near the Banks-Lowman stretch, for example, past medical expenses might include the first helicopter transport, trauma care, and weeks of rehab bills that arrive afterward.

These costs matter right away because they are a core part of economic damages and often anchor the value of a settlement. Insurers usually look closely at whether the treatment was necessary, whether the charges were reasonable, and whether records connect the bills to the injury. Gaps in treatment, missing records, or unpaid balances can create disputes. Health insurance payments, provider balances, and liens can also affect what a person actually keeps.

Time is a real issue. In Idaho, most injury lawsuits are governed by Idaho Code § 5-219 (2024), which generally gives two years to file. Idaho's comparative negligence law, Idaho Code § 6-801 (2024), can also reduce recovery if the injured person is found partly at fault.
