How to Fill Out and Submit an Accident Insurance Claim Form

To fill out an accident insurance claim form, complete the claimant statement yourself with your policy number and a brief factual description of the accident, have the treating doctor complete and sign the attending physician statement, attach itemized bills and medical records, and submit the package to your insurer by mail, fax, or secure portal within the deadline in your policy. The form has two halves and you cannot fill out the doctor’s half. Get both signed, keep copies of everything, and the check typically arrives in four to six weeks.

What to Gather Before You Start

Pull your documents together before you open the form. Looking for a policy number halfway through a fillable PDF is how fields end up blank.

  • Your policy or certificate number, found on your insurance card, your benefits enrollment confirmation, or the certificate your employer issued when coverage started. Group plans also require a group number.
  • Your full legal name, date of birth, mailing address, and daytime phone number, exactly as they appear on the policy.
  • The date, time, and location of the accident, plus a short description of how it happened.
  • Itemized billing statements. Hospitals bill institutional charges on the UB-04 (CMS-1450) and physician offices bill on the CMS-1500; your insurer may ask for copies of either or both.1Centers for Medicare and Medicaid Services. Institutional Paper Claim Form CMS-1450
  • Medical records: radiology reports, diagnostic results, ER records, operative notes. For a fracture benefit, a radiology report is typically required.2Blue Cross and Blue Shield of Texas. Accident Insurance Claim Form
  • Any accident report: a police report if a vehicle was involved, or an incident report if the injury happened at work, at school, or during a sponsored activity.3Boston Mutual Life Insurance Company. Accident Claim Form

Providers may charge a per-page fee for copying medical records, and the amount varies by state. Budget for it so record retrieval doesn’t hold up your filing.

One more thing before you start: use your carrier’s own current form. Generic or outdated versions often leave out fields the insurer requires. Download the latest version from your carrier’s site or ask for one. Under the NAIC model act adopted in most states, insurers must furnish claim forms within 15 calendar days of a request.4NAIC.

Filling Out the Claimant Statement

The claimant statement is the half you complete. Depending on the carrier it may be labeled “Claimant Statement,” “Employee Statement,” or “Section A.” The content is the same.

Start with identification: full name, policy or certificate number, group number if the policy is employer-sponsored, Social Security number, and contact details. Your name on the form must match your policy exactly. A nickname or a maiden name here triggers a verification delay. If the form asks for your employer’s name, address, and phone, fill those in too; most group accident policies ask.

The accident narrative is the part that matters most. The form gives you a few lines or a small text box to describe how and where the injury occurred.5AIG. Accident Insurance Claim Form Keep it factual: what you were doing, what happened, what body part was injured, and the immediate treatment. Something like “Slipped on wet stairs at work on March 12, fell and fractured left wrist, treated in ER same day” is the right level of detail. Don’t editorialize about fault or stretch the symptoms. The medical records do that work.

Watch for the questions asking whether the injury is work-related or involved a motor vehicle. Answer honestly, because the answers decide whether your accident policy pays first or whether workers’ compensation or auto coverage takes priority. If you check “yes” on the employment question, the insurer will coordinate benefits and may require a workers’ comp denial letter before paying.

Then sign and date it. The signature block almost always includes an authorization letting the insurer pull medical records and coordinate with other insurers. Without that signature, intake stops.

The Attending Physician Statement

The second half of the form is the attending physician statement, or APS, and the licensed provider who treated your injury has to complete it. You cannot fill this out for them. Hand or send the form to the doctor’s office and ask them to turn it around.

A typical APS asks for:6New York Life. Attending Physician Statement for Accident

  • The date of the accident, date of first treatment, and dates of any hospital admission and discharge, including ER, observation, ICU, and rehabilitation stays.
  • Primary and any secondary diagnoses with ICD-10 codes.
  • A narrative describing the diagnosis and how it ties to the accident.
  • Whether surgery was performed, the date, and a description of the procedure.
  • Physician credentials: name, specialty, practice name, address, and signature.

The physician’s signature is as essential as yours. A claim with a complete claimant statement but an unsigned APS sits in limbo until the signed version arrives. If the office is slow with paperwork, follow up. Your filing deadline runs regardless.

Submitting the Completed Form

Once both halves are signed and your supporting documents are organized, you’re ready to send the package in. Carriers generally accept one of three channels.

Mail. The claims mailing address is on the form or in your policy documents. Send it by certified mail with return receipt requested. That gives you a postmarked date proving timely filing and a signed receipt confirming the claims department got it. Photocopy everything before you seal the envelope.

Fax. If the form lists a secure claims fax, this is faster than mail. Keep the transmission confirmation page as proof of the submission date.

Online portal. Many carriers now accept uploads through a secure member portal. Scan your form and attachments as PDFs at a resolution high enough that billing codes and physician handwriting are legible. The portal gives you a confirmation number or transaction ID. Save or screenshot it immediately.

Whichever channel you use, keep a complete copy of every page you send. If the insurer later says it never received an attachment, your copies are your evidence.

Deadlines You Have to Meet

Most accident policies require you to notify the insurer “promptly” or “as soon as practicable” after an injury. Some policies specify a window of 30 days; others use open-ended language. Check the claims-reporting provision in your own policy for the exact wording. The formal proof of loss, meaning the completed claim form with medical documentation, typically has to follow within 90 days of the accident, though some policies give you longer.

Missing the notification deadline doesn’t automatically kill a claim, but it gives the insurer a clean reason to deny. File as soon as you have enough medical documentation to support the claim. Don’t wait on the last bill. You can usually send supplemental records in later.

If the Claim Is for a Fatal Accident

When the insured person dies, the designated beneficiary files instead. The form is similar, but additional documents are required: at least one certified copy of the death certificate,7AVMA Life. Accidental Death Claim Form a coroner’s or medical examiner’s report when cause of death needs verification, the original insurance certificate if you have it (and a written explanation if it’s lost), certified executor appointment papers if the estate rather than a named beneficiary is filing (a will alone isn’t accepted), and court custodianship documents if the beneficiary is a minor. Expect these claims to take longer because the insurer has to verify the chain of authority and confirm the death was from a covered accident.

What Happens After You Submit

Once the claim arrives, the insurer opens a review. The timeline is broadly consistent across states, many of which have adopted a version of the NAIC claims settlement standards.

The insurer should acknowledge receipt within 15 days.8NAIC. Unfair Property/Casualty Claims Settlement Practices Model Regulation After receiving your completed proof of loss, it has a limited window to accept or deny: 21 days under the NAIC model regulation. If accepted, payment follows within 30 days of that determination. In practice, expect roughly four to six weeks from submission to payment when the paperwork is complete.

If something is missing, the adjuster will send a written request listing exactly what they need. Respond quickly. The review clock pauses while the insurer waits, and long silences can get the file closed.

Payment arrives as a paper check mailed to your address on file or as a direct deposit to a bank account you designate. Some carriers let you pick during the claims process; others default to a check.

Common Reasons Claims Get Denied

Accident insurance doesn’t cover every injury. If your situation falls into a policy exclusion, the insurer will deny regardless of how cleanly you filled out the form.

  • Pre-existing conditions. If the injury aggravated something you were already being treated for, the insurer may deny or reduce the benefit. Policies define pre-existing using a look-back period, commonly 90 days to six months before coverage started. Anything diagnosed, treated, or medicated in that window is usually excluded.
  • Intoxication. Injuries sustained while legally intoxicated are excluded under most policies. The insurer may request toxicology results from your records.
  • Illegal activity. Injuries sustained while committing a crime, including driving under the influence, are almost universally excluded.
  • Self-inflicted injuries. Intentional self-harm is excluded. So are injuries from activities the policy specifically names, such as skydiving or bungee jumping under some contracts.
  • Injuries covered elsewhere. If workers’ compensation or auto insurance covers the same injury, the accident policy may not pay, or may pay only the difference after coordination of benefits.

Read the exclusions section before filing. If your situation sits in a gray area, say a sports injury where the policy excludes “extreme sports” but doesn’t define the phrase, file anyway and make your case. The insurer has to point to a specific exclusion to deny you.

Mistakes That Delay Payment

Most problems trace to preventable paperwork errors. A short checklist before you submit:

  • Submit everything at once. A complete package processes faster than one submitted in pieces.
  • Match names and numbers exactly to your policy. Transposed digits or a misspelled name creates a matching failure at intake.
  • Confirm the physician actually signed the APS. An unsigned APS is the single most common reason claims stall.
  • Don’t leave the accident description blank. A blank narrative forces the adjuster to ask for clarification. Two or three sentences will do.
  • Keep copies of every page you send and every confirmation you receive. If a dispute arises months later, your file is your defense.
