Injuries and Medical Treatment

The medical record created in the days after a collision does two jobs. It gets you treated, and it is the evidence that later connects your injury to the crash. Gaps in it are hard to repair afterwards.

The short answer

Get examined promptly even if you feel able to carry on, describe every symptom rather than only the worst one, follow the treatment plan, and keep your own record alongside the clinical one. Delay and gaps in treatment are the two things most often used to argue an injury was not caused by the collision.

Why prompt examination matters twice over

The medical reason is straightforward. Adrenaline masks pain, and several serious conditions, including head injuries and internal bleeding, can present hours or days later. Feeling fine at the roadside is not reassurance.

The second reason is evidential. A medical record created close to the collision links the injury to the collision. One created three weeks later invites the argument that something else caused it. That argument is made routinely, and the answer to it is contemporaneous notes rather than recollection.

Describe everything, not just the worst thing

People instinctively report their most painful symptom and leave out the rest. The consequence is a record that mentions a shoulder and says nothing about the headaches, the disturbed sleep, the numbness in two fingers or the difficulty concentrating.

Months later, when those turn out to be the problems that persist, there is no record that they existed early on. Mention everything, however minor it seems, and mention it each time it is still present.

Gaps in treatment

A gap in treatment is one of the most common arguments used to reduce a claim. The logic offered is that if you had really been injured, you would have kept attending.

Real life produces gaps for entirely ordinary reasons: work, childcare, cost, transport, waiting lists, or simply feeling briefly better. None of that is unreasonable. But if a gap is unavoidable, it helps enormously if the reason is recorded somewhere at the time rather than explained afterwards.

Keep your own record

Clinical notes capture the clinical picture. They do not capture what you could not do. Keep a short, dated note of pain levels, sleep, missed work, tasks you needed help with, and activities you had to give up. A few lines a week is enough.

This is often the only evidence of how an injury actually affected daily life, which is a substantial part of what a claim is about.

Paying for treatment while fault is unresolved

This is where California being a fault state bites hardest. The at-fault driver's insurer will not usually pay medical bills as you incur them; it pays once, at settlement. In the meantime the bills are yours.

The usual routes are your health insurance, medical payments coverage on your auto policy if you have it, and in some cases arrangements where a provider treats on the basis of being paid from any eventual settlement. Each has consequences, including reimbursement rights that reduce what reaches you at the end. It is worth understanding those before committing rather than after.

Keep the paperwork

Every bill, every explanation of benefits, every discharge summary, every prescription receipt, every mileage log for medical travel, every note recording time off work. Claims are quantified from documents. Anything undocumented is difficult to include.

A note on scale

16,638 people suffered a suspected serious injury on California roads in 2023, the most recent year for which an injury figure has been published. California has not published a total covering all injury severities since 2020, which is worth knowing if you see confident-sounding recent totals elsewhere.
