How to File a
Workers' Comp Claim in Ohio

Why how you file matters more than you think

Every Ohio workers’ compensation claim begins with a single document: the First Report of Injury (FROI). This form is what opens your claim with the Ohio Bureau of Workers’ Compensation (BWC), and the information on it follows your claim for its entire life. In Mike’s experience, more claims are damaged by careless filing than by any employer tactic or legal technicality.

The FROI captures who you are, who your employer is, when and how the injury happened, and — critically — which body parts were injured. If you leave a body part off the FROI, adding it later requires a formal motion to amend the claim, which the employer can contest. Mike has seen workers lose benefits for knee injuries because they only listed their back on the original filing, assuming “the doctor will sort it out later.” The doctor doesn’t sort it out. The FROI does.

Ohio’s workers’ compensation system is an administrative system, not a courtroom system. That means paperwork, deadlines, and procedural compliance determine outcomes more often than the facts of your injury. Filing correctly from day one puts you in the strongest possible position for every decision that follows.

Under R.C. § 4123.84, you have one year from the date of a traumatic injury to file your claim — but waiting even a few weeks weakens your case. Employers and the BWC will argue that if the injury were really serious, you would have filed immediately. In Mike’s decades of practice, he has never seen a case improved by delay.

Step 1: Report the injury to your employer immediately

The moment you are injured at work, report it to your supervisor. Do not wait until the end of your shift, the next morning, or Monday. Every hour you delay gives the employer and their insurance carrier ammunition to argue the injury didn’t happen at work — or didn’t happen at all.

Ohio law under R.C. § 4123.84 requires written or facsimile notice of the specific body parts claimed (though verbal telephone notice may be accepted under certain conditions), and verbal reports are dangerously easy for employers to deny. Mike always advises clients to file a written incident report with their employer and keep a personal copy. Include the date, time, location, what happened, who witnessed it, and every body part that was injured.

Tell a co-worker what happened. If possible, photograph the scene. These small steps take five minutes and can save your entire claim months or years later when memories fade and witnesses become unavailable.

Step 2: Seek medical treatment the same day

Go to a doctor, urgent care, or emergency room the same day you are injured. When you see the physician, describe every symptom and every body part that hurts — even if the pain seems minor. The doctor’s initial notes become the medical foundation of your claim. If a body part isn’t mentioned in the first medical record, the BWC and employer will argue it wasn’t really injured at work.

You have the right to see any BWC-certified physician of your choice — your employer cannot force you to see their company doctor exclusively. Under Ohio’s Managed Care Organization (MCO) system, treatment must be provided by a BWC-certified provider, but the choice of which certified provider is yours.

Step 3: File the First Report of Injury (FROI)

The FROI is the official document that creates your claim in the BWC system. It can be filed by you, your employer, or your treating physician. In practice, the hospital ER or Urgent Care Facility usually files it — but never assume your employer will file on your behalf. Mike has handled hundreds of cases where workers waited weeks for an employer who never filed.

You can file the FROI online through the BWC’s website, by fax, or by mail. The online filing system is the fastest method. You will need your Social Security number, employer information, date and time of injury, a detailed description of how the injury occurred, and every body part affected.

Step 4: Understand the BWC decision process

After the FROI is filed, the BWC assigns your claim two key contacts. The first is a Claims Service Specialist (CSS), a BWC employee who manages the administrative side of your claim — processing paperwork, issuing orders, and coordinating between parties. The second is a Managed Care Organization (MCO), a private company contracted by the BWC to manage your medical treatment.

The MCO is not your health insurance. It operates on a different set of rules, covers only conditions allowed in your claim, and requires prior authorization through C-9 forms for most treatment beyond the initial visit. The MCO has the power to approve or deny medical services, and their denials can be appealed.

The BWC must issue an initial allowance or denial order within 28 days of receiving the FROI. If your claim is allowed, you will receive an Injured Worker ID card from your MCO, which you present to medical providers for treatment related to your allowed conditions. If the claim is denied, you have exactly 14 days from receipt of the denial order to file an appeal to the Industrial Commission.

In Mike’s experience, roughly 30% of initial FROI filings are denied — often for technical reasons that can be corrected on appeal. A denial is not the end. It is the beginning of a fight that an experienced attorney knows how to win.

Common filing mistakes Mike sees every week

After decades of handling Ohio workers’ compensation claims, Mike has identified the filing errors that cause the most damage:

• Listing only the “worst” body part — If your fall injured your back, hip, and wrist, all three must be on the FROI. Leaving one off doesn’t make the claim simpler; it makes that body part unfunded.
• Vague injury descriptions — “Hurt at work” is not a description. Write exactly what happened: “Slipped on wet floor in warehouse while carrying 40-lb box, fell on left side, hit head on shelf.”
• Assuming the employer filed the FROI — Your employer is required to report the injury under R.C. § 4123.83, but many delay or “forget.” Verify the FROI was filed by checking the BWC website or calling the BWC directly.
• Waiting weeks or months to file — Every day of delay gives the employer ammunition to argue the injury didn’t happen at work. File immediately.
• Not keeping personal copies — Keep copies of every document: the incident report, the FROI, medical records, and every piece of correspondence. Your employer’s records may “disappear.”
