If the ER said "follow up in a few days" and your husband does not, the insurance company will use that gap to argue he was not badly hurt, got hurt somewhere else, or made his condition worse by waiting.

The basic chain is simple: delayed treatment usually means a weaker injury claim, lower settlement offers, and more fights over which medical bills they will pay.

The complications are these:

• Delayed symptoms are real. Whiplash, concussions, back injuries, and shoulder problems often show up a day or two later, especially after a hard stop near a school zone or bus stop. But in Wyoming, the insurer will still ask why he did not go back sooner once pain started.
• Doctor instructions matter. If the Cheyenne ER or urgent care told him to see his primary doctor, get imaging, or start physical therapy, skipping that gives the adjuster a clean argument that he failed to follow medical advice.
• Pre-existing conditions make gaps worse. If he already had neck, back, or knee issues, the insurer may blame everything on the old condition unless the records clearly show the crash made it worse.
• Independent medical exams are not neutral. If treatment drags on or the insurer disputes it, they may send him to an IME doctor. That doctor often focuses on treatment gaps and says further care is unnecessary.
• Bills can pile up fast. Health insurance may pay first, but providers can still seek payment, and any settlement may have to address liens or reimbursement claims.
• Reportable crash rules still exist. If the crash caused injury, death, or $1,000 or more in property damage, Wyoming expects a report to law enforcement, and the Wyoming Department of Transportation may be involved in the crash record.

In Cheyenne, quick follow-up care creates the timeline that proves the crash on I-25, a city street, or a school-zone road caused the injury. Without that timeline, the insurer has room to deny, delay, and discount.
