Why workers’ comp claims get denied
Denials are not improvised. Insurers contest a short list of things, and the notice you receive almost always names one of them. Each reason below is written the way a state agency describes it, with the state named, because what counts as a valid reason is state law.
The injury was not reported in time
This is the cheapest denial to issue and the hardest to cure. Texas tells injured employees to report the injury to the employer within 30 days of the date of injury and to file the claim with the Division of Workers’ Compensation within one year, and says a work injury not reported or filed on time may not be compensable. Illinois requires notice to the employer as soon as practicable and no later than 45 days after the accident, orally or in writing. New York asks for written notice to the employer within 30 days and warns that failing to give it may cost you your right to benefits.
The insurer says the injury did not come from the job
Texas frames the test as course and scope of employment: at the time of the injury you were doing activities related to the business of your employer and furthering the interests of your employer. Illinois puts the same question to the worker as one of the things the employee has to prove, that the injury arose out of and in the course of employment. A denial on this ground is an argument about where you were and what you were doing, and it is answered with witness statements and the injury report rather than with medical records.
There is not enough medical evidence linking the condition to the work
Texas says outright that an insurance carrier may dispute a claim if it believes there is not enough information to show that your work activities caused an injury, illness or medical condition. Illinois lists causal connection as a separate issue the employee must prove. This is the reason that responds to documents: a treating physician’s report that states, in the doctor’s own words, what the work activity did to the body.
A pre-existing condition is blamed instead
A degenerative spine, an old knee, a prior claim: the insurer argues the job did not cause the problem it found on the imaging. Illinois writes the causation issue as whether the medical condition was caused or aggravated by the alleged accident or exposure, so aggravation is inside what the Illinois act reaches. Whether an older condition reduces an award, and by how much, is a separate state-law question that a licensed attorney in your state can answer for your state.
The employer says you were not its employee
Independent contractor classification, staffing arrangements and casual work all produce this denial. Illinois lists employment as one of the five things the employee must prove: that on the date of the accident a relationship of employee and employer existed between the parties. It is proved with pay records, schedules, instructions you were given and who supplied the tools, not with medical evidence.
An exception to liability applies
Several state acts carve out conduct that takes an injury outside coverage even when it happened at work. Texas lists its exceptions plainly, drawn from Labor Code 406.032: you were intoxicated when you were hurt; you meant to hurt yourself or another person; another person meant to hurt you for reasons unrelated to work; you were hurt during an off-duty recreational, social or athletic activity; the injury was caused by an act of God and you were at no greater risk than the general public; or you were hurt during horseplay. Other states carve differently, so read your own act.
The filing deadline in the statute has already passed
This one ends the claim rather than shaping it. Florida bars a petition unless the employee advised the employer of the injury and the petition is filed within two years after the employee knew or should have known the injury arose out of work performed in the course and scope of employment, with payment of benefits or treatment tolling that period for one year. California allows one year from the date of injury, from the end of a period covered by payment, or from the last date medical benefits were furnished. Texas gives one year from the date of injury to file with the division.
