Workers' Comp Laws in Arizona

Getting hurt on the job is stressful enough without also trying to decode the paperwork. Workers' compensation is a no-fault benefit: if the injury is job related, you get medical care and, if you lose time from work, wage benefits — no matter who caused the accident. Your employer pays the entire premium, and Arizona law forbids deducting any part of it from your wages. This guide sticks to Arizona's own rules, drawn from the Industrial Commission of Arizona's Workers' Compensation Information for the Injured Worker booklet and the Arizona Revised Statutes.

The Deadlines, Up Front

Three things can cost you your claim. Read this before anything else — and read the exceptions, because Arizona law writes several of them right into the same statutes.

• Report the accident to your employer FORTHWITH. Under A.R.S. § 23-908(E) you must report the accident and the injury to your employer forthwith, and § 23-908(F) says that if it is not reported forthwith by you or your physician, "no compensation shall be paid for the injury claimed to have resulted from the accident." That is a forfeiture, not just a delay. But the same subsection lets the Commission excuse it — see below. A late report is not automatically the end of the claim.
• File a written claim with the Industrial Commission of Arizona within ONE YEAR. Under A.R.S. § 23-1061(A), no claim is valid or enforceable unless it is filed with the Commission in writing within one year after the injury occurred or the right to compensation accrued. The clock starts when the injury "becomes manifest" — when you know, or with reasonable diligence should know, that you have a compensable work-related injury. The same subsection contains two express excuses. The one-year limit does not apply where you delayed filing "because of justifiable reliance on a material representation by the commission, employer or insurance carrier," or where you were "insane or legally incompetent or incapacitated" at the time the injury occurred, at the time the right to compensation accrued, or during the one-year period after. (If the incapacity begins after the year starts running, the remaining time is suspended while it lasts.) If an adjuster strung you along, or you were hospitalized, comatose, or legally incompetent during that year, file anyway and say so — do not assume you are barred.
• Protest any Notice of Claim Status within 90 DAYS. If the insurance carrier denies your claim, cuts off benefits, or changes your status, you have 90 days to request a hearing (A.R.S. § 23-947). Miss it and the decision is final — unless one of the three statutory excuses in § 23-947(B) applies, which are set out in the appeal section below.

What to Do First

1. Get medical care. If it's an emergency, go to the emergency room or call 911. Tell the doctor's office or ER that this was an on-the-job injury.
2. Tell your employer — forthwith. A.R.S. § 23-908(E) requires you to report the accident and the resulting injury to your employer forthwith — as soon as it happens, or as soon as you become aware of the condition, which matters for gradual-onset and repetitive-strain problems. This is more than a paperwork courtesy. Under § 23-908(F), if the accident is not reported forthwith by you or by your physician, "no compensation shall be paid for the injury claimed to have resulted from the accident."
   
   If you already reported late, read this next part. That same subsection gives the Commission the power to "relieve the injured person or that person's dependents from the loss or forfeiture of compensation if the commission believes after investigation that the circumstances attending the failure… to report the accident and injury are such as to have excused them." In other words, the excuse is written into the statute. Report it now, file your claim, and tell the ICA plainly why the report was late — for example, you didn't realize the condition was work related, you were in the hospital, or you were told not to bother. A late report is a problem to explain, not necessarily a dead claim.
   
   Once your employer has notice of the accident, it has ten days to report it to its insurance carrier and to the Commission (A.R.S. § 23-1061(E)).
3. Sign the claim form. At the doctor's office or ER you should be handed the "pink form" — the Worker's and Physician's Report of Injury. Signing it is how you apply for benefits. If you don't get one, the ICA has a Worker's Report of Injury form on its site or at its offices. Telling your employer is not the same as filing a claim; the claim has to reach the Commission.
4. Watch for a letter from the ICA. Once the ICA receives your form, it notifies the correct insurance carrier and sends you a letter naming that carrier. If you haven't received that letter within 14 days of the injury, the ICA says to contact it to check on the status. The carrier then has 21 days from notification to accept or deny the claim.

Arizona's Workers' Compensation Agency

The Industrial Commission of Arizona (ICA) administers the system. It notifies carriers of injury reports, holds hearings to resolve disputes between injured workers and carriers, monitors how carriers process claims, and runs a Special Fund Division that pays benefits to workers hurt while working for an uninsured employer. Its official website is azica.gov, and its Claims Division answers general questions about the process (it does not give legal advice).

Who Is Covered

Arizona's coverage rule is broad. The ICA states that all public and private employers must provide workers' compensation coverage if they employ one or more persons, full time or part time — there is no minimum employee-count threshold like some states use. A.R.S. § 23-902 extends coverage to the state, counties, cities, towns, municipal corporations, and school districts, and to every person who employs workers regularly employed in the same business. Some categories are treated differently:

• Domestic servants in a private home are exempt under § 23-902(A), though their employer may voluntarily come under the Act.
• Casual work is excluded only when it is both casual and not in the usual course of the employer's trade or business (A.R.S. § 23-901).
• True independent contractors — workers who are independent in how the work is executed and not subject to the business's rule or control — are not employees under § 23-902(C). Being labeled a contractor doesn't settle it; the actual control over the work does.
• Workers who opt out. Every employer must post its notice of industrial insurance coverage, and in the same place make available the form a worker signs to reject coverage under the Act. The ICA is emphatic that such a form only counts if it is completed and given to the employer, in duplicate, before an injury happens.

Arizona is not a monopolistic state-fund state. Employers buy coverage from insurance carriers, or — if they meet the ICA's criteria — they may be authorized to self-insure. There is no single government fund every employer must buy from.

If your employer had no coverage at all on the date of injury, you have a choice: file a civil lawsuit against the employer in Superior Court, or file a claim for workers' compensation benefits with the ICA, which are then paid from the ICA's Special Fund. The benefits are the same, but the claim is processed differently — contact the ICA's Special Fund Division.

Medical Care: Who Picks Your Doctor

This is the question injured workers ask about most, and Arizona's answer has two layers.

If your employer is NOT self-insured: you have the right to select the doctor of your choice. The law does let your employer send you to a doctor of its choosing for one visit. Be careful with what comes next — the ICA warns that if you voluntarily go back to that same doctor more than once, you are treated as having officially chosen that doctor as your attending physician.

If your employer IS self-insured and has contracted medical care registered with the ICA, the employer may have the right to direct your medical care for the entire injury, and a change of doctors is approved only on a very limited basis. Roughly 90 employers in Arizona are self-insured. If you aren't sure whether yours is one of them, ask your employer or call the ICA's Claims Division.

Changing doctors later. Once you have chosen your doctor, A.R.S. § 23-1071(B) says you may not change without written authorization from one of three sources: your attending physician, the insurance carrier, or the Commission. If your doctor won't authorize the change, ask the carrier; if the carrier refuses, you can apply in writing to the ICA, which will issue an award approving or denying the change. Don't start treating with a new doctor before approval — the bills may not be paid.

One rule that surprises people: while you still need medical treatment, you may not leave Arizona for more than two weeks without the Commission's written approval, or you risk forfeiting compensation and medical reimbursement for that period (§ 23-1071(A)).

Wage Replacement Benefits

Arizona has two kinds of accepted claims. A medical-only claim pays your medical expenses when the disability doesn't extend beyond seven consecutive calendar days. A time-lost claim pays medical expenses plus temporary compensation for lost wages.

The waiting period. Compensation is not paid for the first seven days after the injury. If the incapacity extends beyond seven days, compensation begins on the eighth day — but if the disability continues for one week beyond that seven days, compensation is computed retroactively from the date of injury (A.R.S. § 23-1062(D)). The ICA's own example: off 10 days, you're paid for days 8, 9, and 10; off 14 days, you're paid going all the way back. Entitlement runs on calendar days, including weekends and holidays.

The percentage. Temporary total disability pays 66⅔% of your average monthly wage (A.R.S. § 23-1045(A)). If you go back on light duty at reduced earnings, temporary partial disability pays 66⅔% of the difference between what you earned before and what you're able to earn now (A.R.S. § 23-1044(A)). That same subsection says in so many words that "unemployment benefits received during the period of temporary partial disability shall be considered wages able to be earned" — so collecting unemployment while on temporary partial disability reduces the difference the 66⅔% is figured on. Total-disability checks are paid at least every two weeks; partial-disability checks monthly.

Your average monthly wage is usually based on your earnings in the 30 days before the injury, though other methods exist. The law caps the wage figure that can be used in that calculation, and that maximum is adjusted annually — so this guide won't print a dollar amount that would go stale. Ask the ICA's Claims Division or your adjuster for the maximum that applies to your date of injury. The carrier proposes the wage on a Notice of Claim Status with a Wage Calculation Sheet; the ICA reviews it and issues the official Notice of Average Monthly Wage. You have 90 days from that notice to protest the wage — and since every later check is a percentage of that number, it is worth reading closely.

Expect the carrier to send you to a doctor of its choosing for a periodic examination. It has the right to do that at a reasonably convenient time and place, and skipping the exam can get your benefits suspended.

Permanent Disability

If your doctor finds your condition stationary (nothing more can be done to improve it) and you're left with a permanent impairment, Arizona compensates it in one of two tracks. Impairment is usually rated using the AMA Guides to the Evaluation of Permanent Impairment, and permanent compensation is generally paid monthly.

• Scheduled injuries — specific body parts listed in § 23-1044(B), such as a hand, arm, foot, leg, eye, or hearing in one ear — pay for a fixed number of months set by the schedule. The rate depends on the loss: 55% of the average monthly wage for a separation or complete loss of use; 50% for a partial loss of use (prorated to the degree of loss); and 75% if the loss of use leaves you unable to return to the work you were performing when you were injured.
• Unscheduled injuries — anything not on that list, such as a back, hip, or shoulder injury, an occupational disease, or a combination of impairments — are compensated for loss of earning capacity at 55% of the difference between your average monthly wage and what the ICA determines you are able to earn afterward (§ 23-1044(C)). If you're found permanently and totally disabled, the rate is 66⅔% of the average monthly wage for life (§ 23-1045(B)). The ICA — not the carrier — makes the earning-capacity determination, weighing your age, education, previous occupations, physical limitations, and post-injury wages, and issues a Findings and Award.

You, your employer, or the carrier have 90 days from the issuance of that award to request a hearing. On unscheduled awards, you'll also get an "Annual Report of Income" form from the carrier each year on the award's anniversary — failing to return it can suspend your payments. If your earning capacity later changes, either side may file a Petition for Rearrangement or Readjustment of Compensation.

If Your Claim Is Denied — the Appeal Path

This deadline is unforgiving. Any time the carrier or self-insured employer acts on your claim — denying it, changing benefits, closing it — it sends a Notice of Claim Status, and that notice carries a 90-day protest period. Under A.R.S. § 23-947, if you don't get a Request for Hearing into the Commission's possession within 90 days, the determination becomes final and res judicata.

Three excuses for a late protest — and most people only hear about one of them. Section 23-947(B) says the Commission and the courts may not excuse a late filing unless one of the following applies:

• You did not file on time because of justifiable reliance on a representation by the Commission, your employer, or the carrier — and you made a reasonably diligent effort to verify it. (This is the one for the worker whose adjuster said a hearing wouldn't be necessary.)
• You were suffering from insanity, legal incompetence, or incapacity — including minority — when the notice was sent.
• You show by clear and convincing evidence that the notice was not received.

There is a limit, in § 23-947(C): the late filing will not be excused if you or your legal counsel knew — or with reasonable care and diligence should have known — about the notice at any point during the filing period. Still, if you blew the 90 days because you were told a hearing wasn't needed, or because you were hospitalized or otherwise incapacitated, file the Request for Hearing anyway and explain what happened. Don't assume the door has closed on you.

Here is the path:

1. Request a hearing. You can do it by letter or on the ICA's Request for Hearing form. It must be signed by you or your authorized legal representative, and it must actually be filed with — in the possession of — the Commission within the 90 days.
2. Hearing before an Administrative Law Judge. Your request goes to the ICA's Administrative Law Judge Division. The judges are ICA employees who are attorneys licensed to practice in Arizona, and they decide independently of the insurance carrier. You'll get a Notice of Hearing with the date, place, time, and the judge's name. You must appear unless excused.
3. Request for review — 30 days. After the hearing the judge issues an award. It becomes final and not appealable unless a party files a written request for review at the ICA within 30 days of the award date.
4. Arizona Court of Appeals — 30 days. After the judge rules on the review, the parties have 30 days from that decision to appeal to the Arizona Court of Appeals.

Reopening a closed claim. If a new, additional, or previously undiscovered condition develops, you may file a Petition to Reopen with the ICA, supported by a current medical report tying your present condition to the industrial injury. The carrier has 21 days to accept or deny; a denial carries the same 90-day protest period.

You are not required to have an attorney — you may represent yourself, though you'd be following the same hearing rules while the carrier is represented by counsel. Attorneys for injured workers work on contingency; the ICA notes the agreed percentage is usually 25% of the benefits recovered, and there is no fee if they do not succeed.

A Note on Honesty

Workers' compensation fraud — claiming a loss that didn't happen, or inflating the amount or degree of an injury — is a crime in Arizona and can mean forfeiting future benefits. That cuts both ways: report what happened accurately and completely, and don't let anyone pressure you into minimizing a real injury either. Accurate reporting is what protects the claim.

Where to Get Free Help in Arizona

• ICA Ombudsman's Office: free help understanding the system, your notices, and how benefits are calculated, plus assistance resolving problems between you and the carrier. The Ombudsman cannot give legal advice or represent you. Reach it through the Industrial Commission of Arizona.
• ICA Claims Division: general questions about an open claim, the correct forms, whether your employer is self-insured, and the current maximum average monthly wage.
• ICA Special Fund Division: claims against uninsured employers, and vocational rehabilitation or job retraining if your injury keeps you from returning to your regular work.
• State Bar of Arizona: the ICA suggests contacting the state bar for a list of attorneys who specialize in workers' compensation if you decide you want representation.
