In practice, many head injury claims stall for predictable reasons:
- Delayed symptom recognition: Concussion symptoms can show up or worsen after the initial ER visit—especially after a stressful commute or busy workday.
- Treatment gaps: If follow-up care is missed due to scheduling, transportation, or cost, insurers may argue symptoms were mild or unrelated.
- Mechanism vs. symptoms mismatch: When the accident report is vague (or reporting is inconsistent), adjusters may claim the injury is exaggerated.
- Comparative fault arguments: Iowa allows recovery to be reduced based on your share of responsibility. Even if you believe you’re not at fault, adjusters may try to shift blame.
The common thread: valuation comes down to evidence, not estimates.
