The expensive mistake is assuming the insurance company has to follow your VA doctor's opinion. In Iowa, it does not get to choose your doctor in a regular car-accident claim, but it can dispute whether your treatment was caused by the crash, whether it was reasonable, and whether your symptoms came from an older condition instead.

That means your treatment at the Iowa City VA Health Care System is valid medical care. The adjuster cannot erase it just because it was through the VA. But the insurer will compare those records against prior VA records, outside treatment, imaging, and any gap in care. If you wait weeks to mention neck pain, headaches, numbness, or back pain after a fall deer-season collision on I-80, Highway 1, or around Mormon Trek Boulevard, they will argue the symptoms came from something else.

A common Iowa City example: a veteran swerves at dusk in October to avoid a deer, gets hit, feels "shaken up," and only goes to the VA four days later when shoulder and low-back pain get worse. The insurer then says the delay proves the crash was minor, points to an old VA note about back pain, and asks for an "independent" medical exam. That exam is not really independent in the everyday sense; it is a doctor paid to give an opinion for the defense.

What matters most is documentation:

• tell every provider when symptoms started
• report all body parts hurt, even if symptoms were delayed
• make sure VA records note the crash mechanism
• do not leave long treatment gaps without explanation
• keep records of VA payments, because reimbursement issues can come up later

If another driver was involved, Iowa's 51% bar also matters. If the insurer says you were more than 50% at fault for overreacting to the deer, it is trying to defeat the claim entirely, not just discount your medical bills.
