What types of injuries are excluded from workers’ comp coverage?

Generally, injuries resulting from horseplay, self-inflicted injuries, intoxication, and injuries sustained while committing a crime are not covered. For instance, if an employee is injured while engaged in a physical altercation with another employee, it is likely that workers’ comp would not cover their medical expenses. Additionally, injuries caused by a pre-existing medical condition or an illness that is not related to the job may not be covered.
