Getting Medical Help after a Car Accident

The adrenaline wears off somewhere around hour six. People walk away from a collision, decline the ambulance because it costs money they had not planned to spend, drive the rental home, and wake up the next morning unable to turn their head. That sequence is close to universal, and it is the single most common way a legitimate injury claim gets weakened before anyone has spoken to a lawyer. Our Denver car accident lawyers at Boesen Law spend a large part of every case rebuilding a medical record that would have built itself if somebody had been seen on day one.

Colorado had 701 traffic deaths in 2025 according to preliminary data from the Colorado Department of Transportation, up from 689 the year before, with 76 of those in Denver. The people who survive far outnumber the ones who do not, and their outcomes turn on decisions made in the first few days. This post covers what those decisions are, who pays for the treatment while a claim is pending, and how insurers read the timeline afterward.

Why the First Days Matter More Than the First Impression

The body is unreliable as a diagnostic instrument immediately after a crash, and the reasons are physiological rather than psychological.

A collision triggers a surge of adrenaline and cortisol that suppresses pain perception, sometimes for hours. Muscle guarding masks range-of-motion loss. Swelling around a disc or a joint builds over a day or two, so the compression that will eventually cause radiating pain has not happened yet. Bleeding inside the abdomen or the skull can progress for a long stretch before it produces symptoms anyone would think to act on. None of that is unusual, and none of it means the person was not hurt at the scene.

An examination on the day of the crash does two things at once. It catches what needs catching, and it creates a dated record tying the complaint to the collision while nobody can argue about what caused it. The second function is invisible until an adjuster starts asking questions six months later, and by then it cannot be recreated.

The Injuries That Announce Themselves Late

Some conditions are obvious at the roadside. These are the ones that are not, and they account for most of the disputes.

• Concussion and traumatic brain injury. Confusion, light sensitivity, difficulty concentrating, and sleep disturbance often begin a day or more after impact, and a person can sustain a traumatic brain injury without ever losing consciousness or striking their head on anything.
• Whiplash and cervical strain. Neck stiffness that appears the following morning is the textbook presentation, and whiplash is the injury insurers challenge more aggressively than any other precisely because it rarely shows on imaging.
• Disc herniation. Back pain that starts as an ache and becomes numbness, tingling, or weakness in an arm or leg over the following weeks.
• Internal bleeding. Abdominal tenderness, dizziness, deep bruising across the seat belt line, or fainting. This is an emergency room symptom set, not a wait-and-see one.
• Fractures that were read as bruises. Hairline fractures in the ribs, wrist, and sternum are routinely missed at the scene and are one reason imaging matters, since broken bones that heal badly cause problems for years.
• Post-traumatic stress and anxiety. Sleep loss, avoidance of driving, and intrusive recall of the crash are compensable and are almost never documented unless the patient raises them.

Telling the treating provider that the symptoms followed a motor vehicle collision, and giving the date, is what converts a chart note into evidence. It costs nothing and takes one sentence.

What a Gap in Treatment Costs You

Insurers do not evaluate pain. They evaluate documentation, and the shape of the treatment timeline is the first thing they look at.

Two patterns get penalized. The first is the delay between the crash and the initial visit, which an adjuster reads as evidence that nothing much happened, or that something else caused the injury in the interval. The second is the gap in the middle of treatment, where a patient attends physical therapy for three weeks, stops for two months because of work or childcare or cost, and then resumes. In a demand negotiation that gap is characterized as recovery, and everything after it is characterized as unrelated.

Neither reading is usually fair. People stop treatment because they cannot take more time off, or because the copays became impossible, or because they were told to see a specialist and the first appointment was ten weeks out. Those are ordinary explanations, and they carry weight, but they have to be documented in the record at the time rather than explained in a letter afterward. If treatment has to pause, saying why to the provider and having it written down protects the claim.

Who Pays for the Treatment Before the Case Resolves

This is the question that actually stops people from going to the doctor, and it usually has a better answer than they expect.

Medical payments coverage. Colorado requires every auto policy issued in the state to include at least $5,000 in medical payments coverage unless the named insured rejected it in writing or in the same medium the application was taken. C.R.S. § 10-4-635 also requires the insurer to keep proof of that rejection for at least three years. This coverage is no-fault, meaning it pays your treatment regardless of who caused the crash, and it does not require you to sue anyone. A large number of Colorado drivers have it and do not know it. Checking the declarations page is worth ten minutes.

Health insurance. Your health plan pays as it normally would, subject to deductibles and copays. The plan will typically assert a subrogation or reimbursement interest against any eventual settlement, which is negotiable and is handled at resolution rather than upfront.

Provider liens and letters of protection. Some Colorado providers will treat on a lien, deferring payment until the claim resolves. This route is useful for people with no coverage of any kind, though the balances have to be negotiated at the end and should be entered into with a clear picture of what is being agreed.

The at-fault driver’s liability insurance. This one pays last, not first. Liability carriers settle the claim in a single payment at the end, and they do not fund treatment along the way. Waiting for them means waiting years.

Much of what a car accident lawyer does in the early weeks is sequencing these sources so treatment can start immediately without the client absorbing the cost.

Practical Steps in the First Two Weeks

1. Be seen within twenty-four hours, even if you feel fine. Urgent care is sufficient where the emergency room is not warranted. The point is a dated examination.
2. Describe every symptom, including the minor ones. A complaint that goes unmentioned at the first visit is treated as one that developed later. Headache, ringing in the ears, tingling in the fingers, trouble sleeping, and irritability all belong in the note.
3. Say that it was a motor vehicle collision and give the date. Providers cannot record a mechanism of injury nobody told them about.
4. Attend every appointment and every referral. A missed specialist referral is used to argue the injury resolved.
5. Follow the restrictions in writing. If work restrictions were issued, give them to your employer and keep the copy, since that document supports a wage loss claim later.
6. Keep a short symptom log. Two lines a day covering pain level, sleep, and what you could not do. It is the only contemporaneous account of the non-economic side of the injury, and juries find it more persuasive than testimony given two years afterward.

The Filing Deadline Is Longer Than the Evidence Deadline

Most motor vehicle injury claims in this state carry a three-year filing window measured from the collision, set by C.R.S. § 13-80-101, which runs a full year longer than the general personal injury period in § 13-80-102. The older version of this article described that period vaguely and connected it to settling with an insurance company, which is not quite right: the three years is the deadline for filing suit, and your own policy’s notice requirements run on a far shorter and entirely separate schedule.

The practical deadline is shorter still. Intersection camera footage is overwritten in days. Business surveillance recordings are recycled within a week or two. Witnesses change phone numbers. Vehicles get repaired or sold before anyone photographs the damage pattern. The statutory windows for Colorado injury claims are generous by comparison with the window in which a case can actually be proven.

An Attorney’s View on Medical Documentation

Jason Carr worked as a claims adjuster handling auto and first-party homeowner claims before earning his law degree at the University of Denver, and he served fourteen years as a commissioned officer in the United States Army Reserve Military Police Corps. He notes:

“When I was on the other side, the first thing I opened was the treatment chronology, and I made a judgment about the file before I read a single medical narrative. Seen the same day, consistent care, no unexplained holes: that file got valued honestly. Nineteen days to the first visit and a six-week hole in the middle: that file got a letter questioning causation, and it was a letter I could write in ten minutes. None of that means those claimants were exaggerating. It means the record was the only thing I had, and the record made the argument for me. My advice to clients now is the advice I would have hated receiving then. Go the first day, go to every appointment, and if you have to stop, tell the provider why so it is written down.”

Layered coverage often exists on top of the at-fault driver’s policy, including medical payments benefits, uninsured and underinsured motorist coverage on your own household policies, and in some cases a commercial policy where the other driver was working. Identifying all of it before anyone discusses settlement is what prevents a serious injury from being measured against a single policy limit.

What Cases Like Yours Have Recovered

Boesen Law recovered $1,025,000 for a client who was rear-ended in a four-car collision, arrived at the hospital with prior spinal injuries made worse and signs of a concussion, and afterward began therapy for depression and anxiety. The firm also recovered $275,000 for a client hurt in a high-speed rear-end collision who experienced concussion symptoms, whiplash, and continuing significant neck pain with numbness and tingling in the hands. Both files depended on medical documentation that tracked the symptoms as they developed. Our case results reflect what disciplined records make possible.

If you were in a collision and have not been seen yet, the most useful thing you can do today is get examined and say plainly that it followed a crash. The second most useful is to find out what coverage you already carry, because there is a good chance treatment is payable now rather than years from now.

FAQs About Getting Medical Help After a Car Accident

How long after a Colorado crash can I wait before seeing a doctor?

Medically, the answer is that you should not wait at all, because internal bleeding and brain injuries are dangerous specifically because they progress quietly. From a claim standpoint, the first twenty-four to seventy-two hours is where the record is strongest. Beyond about two weeks, an insurer will argue that something in the interval caused the complaint. A delay does not destroy a claim, and people who waited still recover, but the gap has to be explained with something concrete such as a documented work schedule, a wait for an appointment, or a lack of transportation.

Will going to the emergency room make my insurance rates go up?

Treating an injury does not raise your health insurance rates, and using medical payments coverage after a crash you did not cause should not raise your auto premium either, since that coverage is no-fault by design. Colorado insurers set rates on a range of factors, and being the injured party in a collision is not the same as being at fault in one. The far more expensive outcome is skipping treatment for an injury that becomes permanent because it was not caught.

The other driver’s insurer offered to pay my medical bills directly. Should I let them?

Be careful with that offer, and read what accompanies it. Liability carriers occasionally offer to pay early bills, and it is frequently packaged with a release, a recorded statement, or a medical authorization broad enough to pull your entire history rather than the records that relate to this crash. Your own medical payments coverage does the same job with none of those conditions attached. If the offer is genuinely unconditional, it may be worth taking, but the document accompanying it is where the terms live.

Can I still recover if I had a prior injury to the same part of my body?

Yes. Colorado follows the principle that a defendant takes the injured person as they find them, so a crash that worsens a pre-existing condition is compensable to the extent of the worsening. Prior degenerative changes in the spine are extremely common and are not a defense on their own. What the case needs is a clear before-and-after picture: prior imaging, prior treatment records, and a treating physician who can describe what changed. Concealing a prior injury does far more damage than disclosing it, because the insurer will find it in the records anyway.

How long do I have to file a Colorado car accident claim, and does treatment affect that?

Three years from the date of the collision for most motor vehicle injury claims under C.R.S. § 13-80-101, which is longer than the two-year period § 13-80-102 applies to personal injury claims generally. Treatment does not extend that deadline, and finishing treatment is not a precondition to filing. What treatment does affect is valuation, since a claim is difficult to value accurately until a physician can say where the recovery has plateaued. Your own policy’s notice requirements are separate and considerably shorter, which is why the insurer should be notified promptly even when litigation is years away.
