If you were hurt on the job in Las Vegas, the C-4 form is the most important document in your workers’ compensation case. Officially titled the "Employee’s Claim for Compensation / Report of Initial Treatment," the C-4 formally launches your Nevada workers’ comp claim when it reaches the insurer. Without it, your claim does not exist in the system. Whether you work on the Strip, at a warehouse, on a construction site, or behind a delivery wheel, understanding this form can mean the difference between getting benefits on time and facing delays or denials.
If you have questions about the C-4 form or need help with a denied claim, Shook and Stone is here to help. Call 702-570-0000 or contact us today to speak with our team.
How the C4 Form Workers Comp Process Begins in Nevada
Nevada operates under a no-fault workers’ compensation system, meaning you do not need to prove employer negligence to receive benefits. Because workers’ compensation is an exclusive remedy, employers who provide coverage are generally protected from civil lawsuits for workplace injuries, while injured workers receive medical care and wage replacement without litigation.
The claims process follows a specific sequence of C-Series forms maintained by the Division of Industrial Relations (DIR). It starts with the C-1 (Notice of Injury or Occupational Disease / Incident Report), moves to the C-4 (Employee’s Claim for Compensation / Report of Initial Treatment), and triggers the C-3 (Employer’s Report of Industrial Injury or Occupational Disease). Missing any step can stall your claim. Find all current forms on the DIR workers’ compensation forms page.
💡 Pro Tip: Keep personal copies of every form you complete or sign. If a dispute arises about whether a form was filed or what it contained, your records may be your strongest evidence.
The C-1 Form: Your First Step After a Work Injury
Before the C-4 enters the picture, you must notify your employer about your injury using the C-1 form. Under NRS 616C.015, you must provide written notice to your employer as soon as practicable, but no later than seven days after the accident. Filing the C-1 promptly creates a written record that your injury happened at work, but it does not start your claim.
Why the C-4 Form Is the True Starting Point of Your Claim
Your workers’ compensation claim does not officially begin until the C-4 form is completed and filed with the insurer. You will fill out your part of the C-4 form the first time you visit a medical provider for treatment of your work injury. Your treating physician completes the medical section and sends copies to your employer and the insurer.
The C-4 form was most recently revised in August 2021 (8/21), confirming it remains actively maintained. The C-4A (Release of Medical and Other Information), which previously handled medical release authorizations, was discontinued effective September 13, 2023.
What Information Does the C-4 Contain?
The C-4 form captures both your account of the injury and the physician’s clinical findings. You provide details about how, when, and where the injury occurred, along with your employment information. The physician documents the diagnosis, initial treatment, and any work restrictions.
Who Is Responsible for Filing the C-4?
The treating physician or chiropractic physician bears legal responsibility for filing the C-4 with your employer and the insurer within three working days of treatment. Failure to file on time may result in a fine of up to $1,000 per occurrence. While the doctor handles filing, confirm it was sent and keep a copy for your records.
💡 Pro Tip: Ask your doctor’s office to confirm in writing when and where they sent your C-4 form. If the insurer later claims they never received it, this documentation can protect your claim timeline.

Critical Deadlines You Cannot Afford to Miss
Nevada law imposes strict deadlines on every party involved in a workers’ comp claim, and the C-4 form sits at the center of them. Understanding these deadlines helps you hold your employer, your doctor, and the insurance company accountable.
| Form / Action | Who Is Responsible | Deadline |
|---|---|---|
| C-1 (Notice of Injury) | Injured worker | As soon as practicable, but no later than 7 days after the accident (NRS 616C.015) |
| C-4 (Claim for Compensation) | Injured worker + treating physician | Filed with the insurer within 90 days of the accident (NRS 616C.020) |
| C-4 filing with insurer | Treating physician | Within 3 working days of treatment |
| C-3 (Employer’s Report) | Employer | Within 6 working days of receiving the C-4 |
| Claim acceptance or denial | Insurer | Within 30 days of being notified of the accident (NRS 616C.065) |
The 90-day deadline under NRS 616C.020 is particularly important. The claim must be filed within 90 days after the accident, or within 90 days after you first noticed the onset of an occupational disease. Missing this window can bar you from recovering benefits entirely, though Nevada law recognizes limited exceptions under NRS 616C.025. For a detailed breakdown, review these steps to file your C-4 form within 90 days.
💡 Pro Tip: Do not wait until the end of the 90-day window to see a doctor. The sooner the C-4 is filed, the sooner the insurer’s 30-day decision clock begins, and the sooner you may start receiving benefits.
What Happens After the C-4 Is Filed With the Insurer
Once the insurer is notified through the C-4 form, a 30-day countdown begins. Under NRS 616C.065, within 30 days after being notified, the insurer must accept or deny your claim and send you a written determination. If they accept, they must notify you and begin payment. If they deny your claim, you have the right to appeal.
The C-4 also triggers your employer’s obligation to file the C-3 within six working days after receiving a copy from the treating physician.
What If the Insurer Denies Your Claim?
A denial is not the end of the road. Nevada law provides an appeals process for injured workers whose claims are denied. Common denial reasons include disputes over whether the injury is work-related, late filing, or incomplete documentation. If you receive a denial letter, pay close attention to the stated reason and the appeal deadline, which is generally 70 days from the date the insurer mails its determination.
💡 Pro Tip: If your claim is denied, do not assume the insurer is correct. Denials are sometimes based on incomplete information or administrative errors. Seeking legal guidance promptly can help you understand your options within the appeal window.
Common Mistakes Las Vegas Injured Workers Make With the C-4
Filing errors on the C-4 form are one of the most preventable causes of claim delays in Nevada. Here are mistakes to watch for:
- Waiting too long to see a doctor after the injury, which pushes you closer to the 90-day filing deadline
- Providing incomplete or inconsistent details about how the injury occurred
- Failing to verify that the physician actually filed the C-4 within three working days
- Not keeping personal copies of the completed form
- Assuming the C-1 alone is enough to start the claim
Each of these errors can give the insurer grounds to delay or question your claim. Being proactive about accuracy and follow-up protects your interests. Understanding Nevada’s no-fault workers’ comp framework can also help you recognize when an insurer’s response does not align with the law.
💡 Pro Tip: Before signing the C-4, read both sections carefully. If the doctor’s notes do not accurately reflect your symptoms or how the injury happened, ask for corrections before the form is submitted.
How the C4 Form Workers Comp Claim Connects to Your Benefits
The C-4 form is the gateway to your medical treatment, wage replacement, and other benefits under Nevada law. Until this form reaches the insurer, there is no formal claim for the insurer to act on. No C-4 means no 30-day decision window, no obligation to pay, and no benefits flowing to you. Filing the C-4 quickly and correctly puts the legal process in motion and holds the insurer to its statutory timeline.
