Common Reasons Workers’ Compensation Claims Are Denied
California’s workers’ compensation system is supposed to provide injured employees with prompt medical care and wage replacement benefits, regardless of who was at fault. In practice, however, many legitimate claims are denied—sometimes immediately, sometimes after benefits have already begun. For employees who are thrown out of work and dealing with a painful injury, a denial can be confusing, stressful, and financially devastating. Understanding the most common reasons claims are denied is the first step toward protecting your rights and fighting back.
At Invictus Law, P.C., our Southern California workers’ compensation attorneys routinely represent workers in Orange County and the Inland Empire whose claims were unfairly or unreasonably denied by employers and their insurance companies. In many cases, those denials can be challenged and overturned with proper legal representation.
The Insurance Company’s Incentive to Deny Claims
Workers’ compensation insurance carriers are businesses, and they make the most profits when they limit payouts whenever possible. While California law requires insurers to act in good faith, claims administrators scrutinize every file for reasons to delay, dispute, or deny benefits. A denial does not necessarily mean your claim lacks merit, but it often means the insurer believes the claim can be contested.
Under Labor Code §3600, an injury is compensable if it arises out of and occurs in the course of employment. Most denials revolve around disputing one or more elements of that requirement.
Failure to Report the Injury on Time
One of the most common reasons claims are denied is late reporting. California law requires injured workers to notify their employer of a work-related injury within 30 days. This requirement is found in Labor Code §5400.
Insurance companies frequently argue that late notice prevented them from investigating the claim properly or that the injury must not have been serious if it wasn’t reported immediately. This argument is especially common in cases involving cumulative trauma injuries, occupational illnesses, or injuries that initially seemed minor but worsened over time.
Importantly, the law recognizes that not all injuries are immediately obvious. For cumulative trauma cases, the reporting clock generally starts when the worker knew or reasonably should have known that the condition was caused by work. These cases are often denied initially but later accepted after medical evidence is developed.
Disputes Over Whether the Injury Is Work-Related
Another frequent basis for denial is the claim that the injury did not arise out of employment. Insurers may argue that the injury occurred off the clock, off the employer’s premises, during a break, or while commuting.
While injuries during a normal commute are generally excluded, many exceptions apply. For example, injuries suffered while performing job duties off-site, running errands for an employer, traveling between job locations, or attending required work events may still be compensable. Insurance carriers often take an overly narrow view of work-relatedness, forcing injured workers to prove their case through medical evaluations and hearings.
Allegations of a Pre-Existing Condition
Insurance companies frequently deny claims by asserting that the worker’s symptoms are due to a pre-existing condition rather than a workplace injury. This is particularly common in cases involving the back, knees, shoulders, and repetitive stress injuries.
California law does not prohibit compensation simply because a worker had a prior condition. Under Labor Code §4663, employers are responsible when work activities aggravate, accelerate, or exacerbate an existing condition. A denial based solely on pre-existing issues is often improper, but insurers rely on this argument because it creates confusion and discourages workers from pursuing their claims.
Inconsistent or Incomplete Medical Evidence
Medical records play a central role in every workers’ compensation claim. Claims are often denied when initial medical reports are incomplete, unclear, or inconsistent with how the injury was reported.
For example, if an emergency room record fails to mention work as the cause of injury, the insurer may seize on that omission. Similarly, if a treating physician does not clearly connect the injury to work activities, the carrier may deny liability pending further investigation. These denials can often be resolved through Qualified Medical Evaluations (QMEs) or supplemental medical reporting, but without legal guidance, injured workers may not know how to address these issues effectively.
Missed Filing Deadlines
Beyond the 30-day reporting requirement, California imposes a broader statute of limitations. In most cases, a workers’ compensation claim must be filed within one year of the date of injury, as set forth in Labor Code §5405.
Insurance companies may deny claims they believe are time-barred, particularly in cumulative trauma or occupational disease cases where the date of injury is disputed. Determining the correct date of injury is a legal and medical question, and insurers often choose a date that favors denial. An experienced workers’ compensation attorney can challenge these determinations and establish the correct timeline.
Surveillance and Credibility Challenges
Insurance companies sometimes deny claims after conducting surveillance or reviewing social media activity. If footage or online posts appear to contradict reported limitations, insurers may argue that the worker is exaggerating or fabricating injuries.
These denials are often misleading. Short clips taken out of context rarely show whether an activity caused pain or required recovery afterward. Nonetheless, insurers rely on these tactics to dispute credibility. Legal representation is critical in these situations to ensure that evidence is properly contextualized and challenged.
Drug or Alcohol Allegations
Claims may be denied if the insurance carrier alleges that intoxication was the primary cause of the injury. Under Labor Code §3600(a)(4), injuries caused by intoxication may be excluded from coverage.
However, the burden is on the employer or insurer to prove that intoxication was the proximate cause of the injury, not merely that drugs or alcohol were present. Many denials based on this ground are unsupported by sufficient evidence and can be overturned through litigation.
Employer Misclassification or Coverage Disputes
Some claims are denied because the employer alleges the injured worker was an independent contractor rather than an employee. In California, worker classification is governed by the ABC test under Labor Code §2775, and misclassification is widespread.
Insurance companies may also deny claims by asserting the employer lacked coverage or disputing which carrier is responsible. These issues do not eliminate the worker’s right to benefits but often require legal action to resolve.
What to Do After a Denial
A denied claim is not the end of the road. In fact, many workers’ compensation cases begin with a denial and are later accepted or resolved favorably. Once a claim is denied, the injured worker has the right to challenge the decision through the Workers’ Compensation Appeals Board (WCAB).
This typically involves obtaining medical-legal evidence, such as a QME report, and requesting hearings to address disputed issues. Insurance companies are far more likely to reconsider their position once an experienced applicant attorney becomes involved.
