Your doctor ordered surgery, physical therapy, an MRI, or a medication for your work injury - and the insurance company said no. In most systems that is a utilization review denial, and it is important to understand what it is and what it isn't. It is not a ruling that your workers' comp claim is invalid. It is a decision - usually made by a reviewer who never met you - that this one treatment is not medically necessary under the guideline being applied. And where a state provides a route to challenge that decision, it typically runs on its own short clock that you cannot afford to miss.
What utilization review actually is
Utilization review (often shortened to "UR") is a process many states require or allow workers' comp insurers and claims administrators to use before they will authorize certain medical treatment. When your treating doctor requests something - especially something bigger than a routine visit, like surgery, an expensive imaging study, a costly medication, an extended course of physical therapy, or a specialist referral - the request can be routed through a reviewer before it is approved.
That reviewer, typically a physician or nurse working for the insurer or for a utilization review organization it uses, compares the request to a medical treatment guideline that the state has adopted or approved. Those guidelines describe generally accepted, evidence-based care for common work injuries. If the request doesn't line up with the guideline - or if the documentation supporting it is thin - the reviewer can deny it, ask for more information, or approve something narrower than what was requested.
A few things about this process surprise people every time:
The reviewer usually never examines you. The first-level review is generally a paper review: the reviewer reads your records and the request. That is different from an independent medical examination (IME), where a doctor chosen by the insurer or the state actually examines you.
It is a denial of a treatment, not a denial of your claim. Whether your injury arose out of and in the course of your employment - the question at the heart of your claim - is separate. A utilization review denial doesn't undo an accepted claim, and it doesn't touch your wage-replacement benefits directly.
It isn't necessarily personal or final. Denials often happen because the request as submitted didn't include enough documentation to satisfy the guideline, not because the treatment is inappropriate. That is often fixable.
Not every state does this the same way. Formal, guideline-driven utilization review is common but not universal, and the details - who reviews, which guideline applies, what the review deadlines are, and how you challenge a denial - are set by each state.
The challenge path - and why the deadline matters so much
Because a UR denial isn't the end of the story, states generally build in a way to contest it that is faster than a full workers' comp hearing on the merits of a claim. Depending on the state, that can mean asking the claims administrator to reconsider with additional medical documentation; escalating to an independent medical review, in which the dispute goes to an independent reviewer or independent review organization certified or assigned through the state rather than selected by the insurer for your case; or taking the treatment dispute to a workers' comp judge or hearing officer. Some states use more than one of these, in sequence.
Whatever your state's version looks like, the window to act is short, and it varies by state - so find out your specific deadline immediately, not later. The written denial you receive should state the deadline and explain how to contest the decision. Read it the same day it arrives. If it doesn't clearly say, call your state workers' compensation agency or board and ask directly. Don't guess, don't assume you have as long as some other kind of appeal would give you, and don't rely on a deadline you saw described for a different state.
Missing that window can mean losing the chance to challenge that particular denial, even when the treatment was genuinely appropriate. These deadlines are unforgiving precisely because the process is designed to move fast.
What to do when a treatment request is denied
Get the denial in writing and actually read it. The insurer or its utilization review organization should send a written explanation to you and your doctor. Look for the stated reason for denial, which guideline or standard was applied, and - critically - the deadline and process for contesting it.
Call your treating doctor's office right away. Their staff deals with these denials regularly. Ask them to review the stated reason and either supply the missing documentation, request reconsideration, or cite the guideline support for the original request. A denial that says "insufficient documentation" is often the easiest kind to fix.
Calendar the deadline the day you get the letter. Don't wait until you feel ready. If the letter is unclear about the deadline or the process, contact your state workers' compensation agency's information line - most agencies have staff whose job is to answer exactly this question, and many have an ombudsman for unrepresented workers.
Ask whether an independent review step exists in your state. Some states offer independent medical review of medical-necessity disputes; others send them to a judge. Ask your doctor's office or the state agency which applies to you.
Don't stop necessary treatment on your own. If the denial affects care you're currently receiving, talk to your doctor before you stop anything. They can tell you whether a pause is medically reasonable or whether you should continue while the dispute is pending.
Think carefully before paying out of pocket or billing health insurance. It can feel like the only way to keep treatment moving, but it comes with real complications (see below). Ask before you spend.
Consider getting help. A workers' compensation attorney, your state agency's ombudsman or information officer, or a legal aid organization can walk you through your state's specific process and make sure paperwork is filed correctly and on time. Filing and pursuing a claim is a legal right you and your employer paid for - using the appeal process is exactly what it is there for.
The bind: paying out of pocket or using health insurance
If you need treatment now and the dispute is going to take time, you may be tempted to pay for it yourself or bill it to your regular health insurance instead of workers' comp. Both options come with tradeoffs worth understanding before you commit:
Paying out of pocket means fronting money you may not have to spare, and reimbursement later depends on how the dispute turns out - it isn't guaranteed.
Using group health insurance can get you treated sooner, but many health plans exclude injuries that are work-related, and a plan that does pay can assert a lien for reimbursement against a later workers' comp recovery. Money you receive down the road could be owed back.
Neither path is automatically wrong, and neither is automatically safe. Ask your doctor's billing office, a workers' comp attorney, or your state agency's information staff what makes sense in your situation before you spend money you're counting on getting back, or bill an insurer that may come looking for reimbursement later.
Where this fits with the rest of your claim
A utilization review denial is a medical-necessity dispute inside a claim. It is different from the insurer disputing that your injury arose out of and in the course of employment; different from a dispute over your temporary or permanent disability benefits; and different from an independent medical examination, where a doctor examines you and may opine on whether you have reached maximum medical improvement. Retaliation for reporting an injury is a separate employment-law problem. And if your injury keeps you out of work long-term, that can intersect with Social Security disability - a different system with its own rules.
If you are a federal employee, a maritime worker, or a railroad worker, you are not in a state comp system at all: FECA, the Longshore Act, the Jones Act, and FELA are separate programs with their own medical-authorization and dispute procedures (and the Jones Act and FELA are fault-based rather than no-fault). The U.S. Department of Labor's Office of Workers' Compensation Programs administers FECA, Longshore, and Black Lung.
The thing to hold onto: this is usually a fixable, procedural problem with a known playbook - get it in writing, get your treating doctor involved, be accurate and complete about your symptoms and history, and move fast on the deadline. Because the details of that playbook - which guideline applies, who reviews it, and exactly how long you have - are set by your state, confirm the specifics with your state workers' compensation agency or board as soon as a denial arrives.

For guidance on your specific claim, contact your state workers' compensation agency or a workers' compensation attorney in your state.
Frequently asked questions
Does a utilization review denial mean my whole workers' comp claim was denied?
No. Utilization review looks at one specific treatment request - a surgery, a round of physical therapy, an MRI, a medication - and decides whether that particular treatment is medically necessary under the applicable treatment guideline. It is not a ruling on whether your injury arose out of and in the course of your employment, or on whether your overall claim is valid. Your claim can be accepted and still have a treatment request denied. Keep the two straight, because the challenge paths for each are different, and they run on different deadlines.
Who actually reviews the request, and do they examine me?
Typically a physician or nurse reviewer working for the insurer or claims administrator, or for a utilization review organization it uses. That first-level reviewer generally works from your medical records - they usually do not examine you in person. That is why a well-documented, specific request from your treating doctor matters so much. Many states then provide a further, independent step, in which the dispute goes to an independent reviewer or independent review organization that is certified or assigned through the state rather than picked by the insurer for your case. Whether that step exists, and what it is called, depends on your state - ask your state workers' compensation agency.
How long do I have to appeal a utilization review denial?
The deadline is short, and it varies by state - there is no single national number, and the clock commonly starts when the written denial is issued or received rather than when the treatment was requested. The denial letter itself should state the deadline and how to challenge the decision. Read it the day it arrives and act on it. If it does not clearly state a deadline, call your state workers' compensation agency and ask. Do not rely on a number you read somewhere else, including here - only your state's rule and your denial letter control.
Should I just pay for the treatment myself or use my health insurance while I appeal?
Ask before you spend. Talk to your doctor's billing staff and, if you have one, your workers' comp attorney or your state agency's ombudsman or information officer. Using group health insurance sometimes works, but many health plans exclude care for work-related injuries, and a plan that does pay may later assert a lien for reimbursement against your workers' comp recovery. Paying out of pocket means reimbursement depends on how the dispute comes out - it is not guaranteed. There is no one-size-fits-all answer.
Can I just stop the treatment my doctor ordered if comp won't pay for it?
Don't make that call alone. Call your treating doctor and explain what happened. They may be able to submit more documentation, request reconsideration, suggest a guideline-supported alternative, or tell you a pause is medically reasonable. Stopping necessary care without medical guidance can hurt your recovery, and gaps in treatment can also complicate your case later.
Does this apply if I'm a federal, maritime, or railroad worker?
Not in the same way. Federal employees are covered by FECA and maritime and railroad workers fall under the Longshore Act, the Jones Act, or FELA - separate systems with their own medical-authorization and dispute procedures, and the Jones Act and FELA are fault-based rather than no-fault. If you are in one of those systems, follow that program's process instead of a state utilization review process. The U.S. Department of Labor's Office of Workers' Compensation Programs administers FECA, Longshore, and Black Lung.
