First: three things to do today
- Find the deadline in the letter. Every denial starts a clock — often measured in weeks, not months. The appeal deadline is printed somewhere in the notice. Find it, write it down, put it in your phone.
- Don't stop treating. A denied claim doesn't mean you stop being injured. Keep your appointments — through health insurance, state programs, or providers who treat on a lien — because gaps in treatment become the insurer's best evidence.
- Don't take it personally, and don't take it as truth. Denials are a routine, high-volume business decision. Some are legitimate. Many are positions taken because the evidence file was thin — which is fixable.
Why claims actually get denied
Almost every denial letter is built from a short list of arguments. Knowing which one you're facing tells you exactly what evidence fixes it:
| The denial says… | What it really means | What typically fixes it |
|---|---|---|
| "Not work-related" (AOE/COE) | They doubt the injury came from work — the most common denial of all. | Medical records connecting the injury to work, witness statements, a treating doctor's causation opinion, a neutral medical-legal exam. |
| "Late reporting" | You told your employer after the deadline — or they claim you did. | Evidence of earlier notice (texts, emails, coworker knowledge), or an exception — many states excuse late reporting when the employer knew or wasn't prejudiced. |
| "Pre-existing condition" | They attribute your problem to age or an old injury. | The aggravation rule: in most states, work worsening a pre-existing condition is covered. Medical comparison of before vs. after is the key evidence. |
| "No medical evidence" | The file lacks records supporting injury or disability. | Often the easiest fix — missing records get gathered, the treating doctor writes a report, an exam gets scheduled. |
| "Not an employee" | They say you're an independent contractor. | The reality test: how much the company controlled your work. Misclassification is common and frequently overturned. |
| "Post-termination claim" | You filed after being fired or laid off, so they doubt the claim. | Evidence the injury or its report predates the termination — one more reason day-one reporting matters. |
A "delay" notice means the insurer is still investigating — it hasn't said no. Deadlines apply to them too: in California, a claim not denied within 90 days of the claim form is presumed covered, and up to $10,000 of treatment must be paid during the delay.
Decode your denial letter
Denial notices are formulaic. Read yours for four things:
- What exactly is denied. The whole claim? One body part? A specific treatment? Partial denials are common — and each piece is disputed separately.
- The stated reason. Match it to the table above; that's your evidence roadmap.
- The deadline and the named process. The letter must tell you how to challenge it — a hearing request, an appeal form, an application to the state board.
- Who signed it. An adjuster made this call — often without ever speaking to your doctor. That's the level of authority you're appealing against, not a judge.
How the dispute process works
Every state runs its own version, but the shape is the same everywhere:
- 1
You file the challenge
A form or application to your state's workers' comp board — in California, an Application for Adjudication with the WCAB; in Texas, requesting a Benefit Review Conference. Filing is usually simple and protects your deadlines.
- 2
The medical evidence gets built
Disputed medical questions go to a neutral or agreed examiner — a QME/AME in California, a designated doctor in Texas. This exam usually decides the case's trajectory, which is why preparing for it properly matters so much.
- 3
Informal resolution is attempted
Most disputes settle at conferences or mediations once real evidence is on the table. Many denials quietly reverse here — the insurer's position was built for a thinner file than the one that now exists.
- 4
A judge decides what's left
Unresolved disputes go to a hearing before a workers' compensation judge — less formal than TV court, decided on medical records and testimony. Further appeals exist beyond that, with short deadlines at every step.
Not on the merits — on the calendar. Missed appeal windows convert weak denials into permanent ones. If you do only one thing after a denial, calendar the deadline and file the challenge. Everything else can be built afterward.
Is this the moment to get a lawyer?
A denial is the single strongest signal that professional help will pay for itself. Denied claims are exactly what workers' comp attorneys do all day: they know which evidence each denial reason requires, the exam process, and what similar cases resolve for. Fees are state-regulated percentages of what they recover, consultations are typically free — and if they recover nothing, you generally owe nothing.
