Concussion After a Car Accident in Arizona: Why ‘Mild’ TBI Claims Are Denied and What to Do About It

Concussion After a Car Accident in Arizona: Why ‘Mild’ TBI Claims Are Denied and What to Do About It

A doctor called it mild, and now an insurance adjuster is using that same word against you. That is the core reason why ‘mild’ TBI claims are denied or lowballed so often. The label sounds minor, so the claim gets treated as minor. A concussion is a real brain injury, and its effects can last long after the scans come back clean.

Right now you are dealing with headaches, fog, and a settlement offer that ignores all of it. That is exhausting.

Marc Bleaman spent years defending injury claims for insurance carriers before he started taking them on. Bleaman Law Firm knows how adjusters decide what a head injury is worth, because he sat on their side of the table first.

Key Takeaways

  • “Mild” is a triage label based on the Glasgow Coma Scale, not a measure of how much a concussion affects your life or your case.
  • A normal CT or MRI is common after a concussion and does not prove your brain is uninjured.
  • Adjusters lean on a few predictable arguments to shrink these claims: delayed symptoms, gaps in treatment, and pre-existing conditions.
  • Steady medical follow-up is your strongest evidence, and every missed appointment becomes the insurer’s best counterpoint.
  • Arizona gives you two years to file most injury lawsuits, and being partly at fault reduces what you recover without erasing it.

If an adjuster has already called your concussion minor, the Tucson traumatic brain injury team at Bleaman Law Firm can look at your claim before you sign anything. Call (520) 323-1808 for a consultation.

What “mild” really means on a brain injury diagnosis

Mild does not describe your symptoms. It describes your Glasgow Coma Scale score at the hospital, a 13 to 15 on a 15-point scale that measures how awake and responsive you were, not how the injury affects your memory, mood, or ability to work. Diagnosis is a clinical call based on symptoms and history, so the word is medical shorthand. A person rated mild can still lose months to headaches and brain fog. Insurers read that shorthand as small, and the gap between the label and the reality is where your claim gets undercut.

Why your normal scan works against you

A standard CT scan is usually normal after a concussion, and the CDC notes that imaging is not even required to diagnose one. CT is good at spotting bleeding and skull fractures. It is not built to show the microscopic stretching of nerve fibers, called diffuse axonal injury, that drives many concussion symptoms.

An adjuster knows this and uses it anyway. The file shows a clean scan, so the argument writes itself: no visible damage, no serious injury, no reason to pay. Meanwhile your symptoms may not have peaked for hours or days after the crash, and some people carry them for months as post-concussive syndrome. A normal image and a damaged brain can coexist. Proving that connection is the real work of a TBI claim.

The arguments insurers use to deny or shrink a concussion claim

Most concussion denials come from the same short list of adjuster arguments:

  • Delayed symptoms: you did not report headaches at the scene, so they claim the injury came from something else.
  • Treatment gaps: you waited a week to see a doctor or skipped follow-ups, so they argue you were not really hurt.
  • Pre-existing conditions: you had prior headaches or an old injury, so they blame that instead of the crash.
  • Subjective symptoms: fog, irritability, and trouble concentrating do not show on a machine, so they call them exaggerated.

None of these arguments prove you are uninjured. They exist to create doubt, and doubt is what lowers an offer. Each one has a documented medical answer, which is exactly why the records you build now matter so much.

Marc Bleaman built his career reading these arguments from the inside, and now an Arizona brain injury attorney at his firm can answer them with the evidence your claim needs. Call (520) 323-1808 before you respond to a denial.

How Arizona law shapes a TBI claim

Two Arizona rules quietly decide how much leverage you have.

The filing deadline

You generally have two years from the date of the crash to file a personal injury lawsuit in Arizona, under A.R.S. § 12-542. Miss it, and the claim is gone no matter how strong it was. Concussion cases make this risky, because symptoms can surface late and people assume the clock has not started. It started at the crash.

How shared fault affects your payout

Arizona follows pure comparative negligence under A.R.S. § 12-2505, which means your recovery drops by your share of fault but never disappears. If you are found 20 percent responsible for a $100,000 claim, you recover $80,000. Insurers use this rule to pin extra blame on you, since every point of fault they assign is money they keep. A Tucson brain injury attorney can push back on an inflated fault percentage before it costs you.

What to do if your mild TBI claim is denied

A denial is a position, not a verdict. You can respond, and the steps below protect the claim while you do:

  1. Get back into consistent medical care and follow every treatment instruction.
  2. Ask your doctor to document the link between the crash and your symptoms in plain language.
  3. Keep a short daily log of headaches, sleep, focus, and mood so the “subjective” symptoms have a record.
  4. Do not give the insurer a recorded statement or accept a fast settlement before you know the full picture.
  5. Get your file reviewed before the two-year deadline closes your options.

Each step turns a symptom the insurer dismisses into evidence it has to address. That shift, from your word against theirs to a documented record, is what shifts an offer.

Frequently Asked Questions

How much is a mild TBI claim worth in Arizona?

There is no fixed number, because value depends on your medical costs, lost income, and how long your symptoms last. Arizona does not cap most personal injury damages under Article 2, Section 31 of its Constitution, so a concussion with lasting symptoms can be worth far more than a first offer suggests. Get a clear prognosis before anyone attaches a dollar figure.

Should I accept the insurance company’s first offer?

Usually not, especially while your symptoms are still changing. Early offers often land before the full cost of a brain injury is known, and once you sign a release you cannot ask for more later. Have someone review the offer against your actual treatment and future care first.

What if my symptoms did not start until weeks after the crash?

Delayed onset is normal and does not sink your claim. The CDC notes that concussion symptoms can appear hours or days after the injury and sometimes last for months. Tell your doctor the timeline clearly so the delay is explained in your records rather than used against you.

Can I reopen my claim after I already settled?

Almost never, because a signed settlement release usually closes the claim for good, even if your symptoms get worse. That is why timing the settlement to your recovery matters so much. If you have not signed yet, get advice before you do.

Do I need an attorney for a concussion claim?

Not for every case, but denied and disputed claims are where legal help matters most. These claims turn on medical causation and documentation, which insurers are trained to contest. A free consultation costs nothing and tells you whether your claim is being undervalued.
